The quantity "strain" expressed in terms of the fundamental quantities (mass, length, time) is equivalent to 1.

Strain is a dimensionless quantity that represents the relative deformation of a material under an applied force or stress. It can be expressed as the ratio of the change in length (ΔL) to the original length (L₀) of the material. In terms of fundamental quantities, strain can be written as:
Strain = ΔL / L₀

Since both the change in length (ΔL) and the original length (L₀) have the same dimensions of length (L), their ratio will be dimensionless, meaning that strain has no dimensions in terms of mass (M), length (L), or time (T).

Therefore, the strain is equivalent to:
1 (dimensionless)

The net electric field at the center of the square is directed along the positive y-axis and has a magnitude of kq/2^3/2.

We can choose a coordinate system with origin at center of square, so that the position vectors of the charges are:

[tex]r1 = (1,1) \\r2 = (-1,1) \\r3 = (1,-1)[/tex]

The electric field at the center of square due to each charge can be calculated using Coulomb's law:

[tex]E1 = kq(r1 - r)/(r1 - r)^3 \\E2 = kq(r2 - r)/(r2 - r)^3\\E3 = kq(r3 - r)/(r3 - r)^3[/tex]

Since the charges are all of the same magnitude q, the electric fields have the same magnitude:

|E1| = |E2| = |E3| = kq/2^3/2

To find the direction of the electric field at the center of the square, we need to add the three electric fields vectorially:

When a positively charged rod is brought near a positively charged pith ball that is suspended from an insulating string, the pith ball will be repelled by the rod. This happens because like charges repel each other.

The positively charged rod and the positively charged pith ball both have an excess of positive charges, and therefore, they repel each other.

This can be explained by the concept of electrostatic force. Electrostatic force is the force between two charged objects. Objects with the same charge will repel each other, while objects with opposite charges will attract each other. In this case, the rod and the pith ball have the same charge, and so they will repel each other.

The insulating string that suspends the pith ball plays an important role in this scenario. Since the string is an insulator, it does not allow the charges to flow between the rod and the pith ball. Therefore, the pith ball remains charged and is affected by the repulsive force between it and the rod.

In summary, when a positively charged rod is brought near a positively charged pith ball suspended from an insulating string, the pith ball will be repelled by the rod due to electrostatic force.

The spin on a basketball moving horizontally at 10 m/s, such that it begins rising because of the magnus force is  0.19 revolutions per second.

To determine the spin required for a basketball to begin rising due to the Magnus force, we can use the following equation:

Magnus force = (pi/2) * air density * coefficient of lift * radius^2 * velocity^2

The coefficient of lift is a dimensionless constant that depends on the properties of the ball's surface and the angle of attack of the air flow. For a basketball, it is typically around 0.2.

The Magnus force is perpendicular to the velocity of the ball and in the direction of the spin. Therefore, in order to produce an upward force on the ball, the spin must be in the opposite direction to the velocity of the ball.

First, we can calculate the velocity of the ball relative to the air. Since the ball is moving horizontally, the relative velocity is the same as the velocity of the ball, which is 10 m/s.

Next, we can solve for the spin using the Magnus force equation:

Magnus force = (pi/2) * air density * coefficient of lift * radius^2 * velocity^2

Magnus force = (pi/2) * 1.2 kg/m^3 * 0.2 * (0.12 m)^2 * (10 m/s)^2

Magnus force = 0.0137 N

To produce an upward force of 0.0137 N, the spin must be such that the Magnus force is equal and opposite to the gravitational force on the ball, which is:

Gravitational force = mass * acceleration due to gravity

Gravitational force = 0.59 kg * 9.81 m/s^2

Gravitational force = 5.79 N

Therefore, the spin required is:

Spin = Magnus force / (mass * radius * velocity)

Spin = 0.0137 N / (0.59 kg * 0.12 m * 10 m/s)

Spin = 0.19 s^-1

So the basketball must be spinning at a rate of 0.19 revolutions per second, in the opposite direction to its horizontal velocity of 10 m/s, in order to begin rising due to the Magnus force.

Answer: 2.02 seconds.

Explanation:  Let’s solve this problem step-by-step. When an object is dropped from a height, it falls freely under the influence of gravity. The distance fallen by a freely falling object is given by the equation of motion: s = 1/2 * g * t^2, where s is the distance fallen, g is the acceleration due to gravity (9.8 m/s^2 on Earth), and t is the time taken to fall that distance.

In this case, the body of mass 1500g (which is irrelevant to the problem) is dropped from a height of 20m. So we can plug s = 20m and g = 9.8 m/s^2 into the equation above to find the time taken for the body to reach the ground: 20 = 1/2 * 9.8 * t^2. Solving for t, we get t^2 = 20 / (1/2 * 9.8) = 4.08. Taking the square root of both sides, we get t = sqrt(4.08) ≈ 2.02 seconds.

So, a body of mass 1500g dropped from a 20m high tower will reach the ground in approximately 2.02 seconds.

The person needs to consume approximately 1279 kcal/day to make up for the energy loss to the surroundings. The closest answer choice is C) 1300 kcal.

First, we need to convert 62 W into units of kilocalories per day. We can do this using the following steps:

Convert watts to joules per second (J/s):

62 W = 62 J/s

Convert joules per second to joules per day:

1 day = 24 hours x 60 minutes/hour x 60 seconds/minute = 86400 seconds

62 J/s x 86400 s/day = 5,356,800 J/day

Convert joules to kilocalories (kcal):

1 kcal = 4.186 kJ

5,356,800 J/day ÷ 4.186 kJ/kcal = 1279 kcal/day

Therefore, the person needs to consume approximately 1279 kcal/day to make up for the energy loss to the surroundings. The closest answer choice is C) 1300 kcal.

The force constant k of the spring is approximately [tex]3.125 x 10^8 N/m[/tex].

To determine the force constant k of the spring, we can use the equation for the potential energy of a spring:

[tex]U = (1/2)kx^2[/tex]

where U is the potential energy of the spring, k is the force constant of the spring, and x is the displacement of the spring from its equilibrium position.

When the subway train hits the spring bumper, it compresses the spring by a distance of 0.2 m. We can use the work-energy theorem to find the potential energy stored in the spring:

W = ΔK + ΔU

where W is the work done on the subway train by the spring, ΔK is the change in kinetic energy of the subway train, and ΔU is the change in potential energy of the spring.

At the beginning of the collision, the subway train has a kinetic energy of:

[tex]K1 = (1/2)mv^2 = (1/2)(5.00 x 10^5 kg)(0.5 m/s)^2 = 62,500 J[/tex]

At the end of the collision, the subway train comes to a stop, so its kinetic energy is zero. Therefore, the change in kinetic energy is:

[tex]ΔK = K2 - K1 = 0 - 62,500 J = -62,500 J[/tex]

The potential energy stored in the spring is equal to the work done on the subway train by the spring, so:

[tex]ΔU = W = -62,500 J[/tex]

Using the equation for the potential energy of a spring, we can solve for the force constant k:

The sign of momentum is indeed always in the direction of travel.
Momentum is defined as the product of an object's mass and its velocity. Mathematically, it can be expressed as:
Momentum (p) = mass (m) × velocity (v)

Since velocity is a vector quantity that has both magnitude and direction, the sign of momentum will also depend on the direction of the object's motion. If an object is moving in a positive direction (e.g., to the right or upward), its momentum will have a positive sign. Conversely, if an object is moving in a negative direction (e.g., to the left or downward), its momentum will have a negative sign.

In summary, the sign of momentum is always in the direction of travel because it is directly influenced by the object's velocity, which is a vector quantity with both magnitude and direction.

Force is defined as an action that can change any object's state of motion, either by changing its speed or direction.

When force F is applied to block A, it will experience acceleration, which will result in a net force being exerted on block B due to the frictional force between the blocks.

Let a be the common acceleration of the blocks, which is same for both blocks since they are in contact with each other. Net force acting on block A is F - f, where f is frictional force between the blocks. Net force acting on block B is f.

F - f = ma   ; f = mb * a

ma and mb are the masses of blocks A and B, respectively.

F - f = f  ; F = 2f

F = 2mb * a

F = (ma + 2mb) * a

The "m" is the mass of the steam in kg.

To estimate the specific work done by the piston during the compression process, we can use the First Law of Thermodynamics, which states that the change in internal energy (ΔU) of a closed system is equal to the heat added to the system (Q) minus the work done by the system (W):

ΔU = Q - W

Assuming that the process is adiabatic (no heat transfer) and that there are no significant changes in kinetic and potential energies, we can simplify the equation to:

W = ΔU

Where W is the work done by the system and ΔU is the change in internal energy.

The change in internal energy of the steam can be expressed as:

ΔU = m × c_v × ΔT

Where m is the mass of the steam, c_v is the specific heat at constant volume, and ΔT is the change in temperature.

Since the volume ratio is 4:1, the final volume of the steam is one-fourth of the initial volume. Therefore, the initial and final specific volumes of the steam can be calculated as:

v_1 = V_1/m = 4V_2/m = 4v_2

Where V_1 and V_2 are the initial and final volumes, respectively.

Since the process is adiabatic, we can assume that the specific heat at constant volume is constant. Therefore, the change in internal energy can be expressed as:

ΔU = m × c_v × ΔT = m × c_v × (T_2 - T_1)

Where T_1 and T_2 are the initial and final temperatures, respectively.

Substituting the given values, we get:

ΔU = m × c_v × (600 K - 400 K) = m × c_v × 200 K

The specific work done by the piston can be calculated as:

W = ΔU = m × c_v × 200 K

To estimate the specific work done, we need to know the mass of the steam and the specific heat at constant volume. Assuming that the steam is an ideal gas, the specific heat at constant volume can be calculated as:

c_v = (3/2)R

Where R is the specific gas constant for steam. The value of R depends on the units used, and can be found in thermodynamic tables. For SI units, R = 0.287 kJ/(kg·K).

Substituting the values, we get:

c_v = (3/2) × 0.287 kJ/(kg·K) = 0.431 kJ/(kg·K)

Therefore, the specific work done by the piston is:

W = m × c_v × 200 K = m × 0.431 kJ/(kg·K) × 200 K = 86.2 m kJ/kg
