What is the current reading on ammeter A

Answer:

Because fluid pressure increases with depth, there is more fluid pressure___outside__ of a submerged object than on the _inside___

Explanation:

As the object is submerged means that it is under water and not on the surface. It tells that water pressure exerting on the object from the outside is higher than inside which is why the object is submerged.

In the other case, the object will not remain submerged if its internal pressure is high, it will float on water.

Answer:

* If there is no friction  U = 0,  K = 200 J

* If there is friction    U = 0,  K = 200 - W

Explanation:

For this exercise we must make an assumption.

* If there is no friction

   The energy of the system is conserved therefore the energy is transformed.

The potential energy is

      U = m g h

at the bottom of the road there is no height therefore

      U = 0

and all the energy has been transformed into kinetic energy

       K = 200 J

* If there is friction, which can come from the internal friction of the car, the friction force between the car and the floor, etc.

in this case there is a loss of energy due to the work of non-conservative forces (friction).

The potential energy at the bottom of the path is hedron because there is no height U = 0

The kinetic energy is

             K = U -W

             K = 200 - W

where W is the work of the friction force.

Answer:

Height of resulting wave = 0.6 meters

Explanation:

Let the higher wave (wave crest) be A while the lower wave (wave trough) be B.

Given the following data;

A = 3.2m

B = 2.6m

To find the height of the resulting wave;

Height = A + B

But the lower wave becomes negative because it is below i.e on the lower trough.

Height = 3.2 + (-2.6)

Height = 3.2 - 2.6

Height of resulting wave = 0.6 meters

Answer: 2- doubled

Explanation:

Given

for m=0.02 kg, v=5 m/s, kinetic energy is 0.25 J

for same velocity and double mass i.e.

m=0.04 kg, v=5 m/s, kinetic energy is 0.50 J

same is with

m=0.08 kg, v=5 m/s , kinetic energy is double to [tex]2\times 0.5=1\ J[/tex]

So, on doubling the mass, kinetic energy is doubled

Answer:

P = 6000 W

Explanation:

The given question is "The motor of a motorcycle gives it a speed of 90 km / h when a force of 240 N is applied to it. What is the power of the motorcycle in watts?"

Given that,

Speed of a motorcycle, v = 90 km/h = 25 m/s

Force applied to the motorcycle, F = 240 N

We need to find the power of the motorcycle. We know that,

Power = Fv

So,

P = 240 N × 25 m/s

= 6000 W

So, the required power of the motorcycle is equal to 6000 W.

Answer:

T = 0.96 seconds

Explanation:

Given that,

The speed of wave, v = 2.6 m/s

The distance between wave crests, [tex]\lambda=2.5\ m[/tex]

We need to find the period of the wave motion. Let T be the period. So,

[tex]v=\dfrac{\lambda}{T}\\\\T=\dfrac{\lambda}{v}\\\\T=\dfrac{2.5}{2.6}\\\\T=0.96\ s[/tex]

So, the period of the wave motion is equal to 0.96 seconds.

The period of the wave motion is 0.96 seconds.  Using the formula:

v = λ / T

where v is the velocity of the wave, λ is the wavelength and T is the period of the wave.

Given that v = 2.60 m/s, λ = 2.5 m, hence:

2.6 = 2.5/T

T = 0.96 s

The period of the wave motion is 0.96 seconds.

Answer:

 θ = 73.6º

Explanation:

To solve this exercise, let's use Newton's second law. Let's set a reference system where the x-axis is parallel to the inclined plane

with trigonometry we can find the components of the weight

           sin θ = Wₓ / W

           cos θ= W_y / W

           Wₓ = W sin θ

           W_ = W cos θ

Y axis  

           N - W_y = 0

           N = W_y

X axis

           Wₓ - fr = m a

            mg cos θ - fr = m a

indicate that friction is zero, fr = 0

            cos θ = a / g

            θ = cos⁻¹  [tex]\frac{a}{g}[/tex]

let's calculate

            θ = cos⁻¹  [tex]\frac{2.77}{9.8}[/tex]

            θ = 73.6º

Speed has no direction.

Answer:

The formula for calculating Density is:

= Mass / Volume

From this formula, we can say that the relationship between Mass and Density is a direct one. In other words, if mass is increasing - all else being equal - then density will increase as well.

If mass however was decreasing, density would have to decrease as well.

For example, assume 3 bricks have masses of 5kg, 10kg and 15kg. Also assume that the bricks all have the same volume of 5 m³.

Density of 5kg brick = 5 / 5 = 1 kg/m³

Density of 10kg brick = 10 / 5 = 2kg / m³

Density of 15kg brick = 15 / 5 = 3 kg /m³

Notice how density increases as mass increases and decreases when mass decreases.

Answer:

The work is done by the force 100 NM.

Explanation:

=5kg * 2 m/s^2

=5* 2 N (kg*m/s^2=N)

=10N

Work done = force* distance

=10N* 10

= 100 NM

For an object of mass 5 kg accelerating at the rate of 2 m/s², then the work done by the force on the object will be 100 Nm.

In physics, the word "work" involves the measurement of energy transfer that takes place when an item is moved over a range by an externally applied, at least a portion of which is applied within the direction of the displacement.

The length of the path is multiplied by the element of a force acting all along the path to calculate work if the force is constant. The work W is theoretically equivalent towards the force f times the length d, or W = fd, to portray this concept.

As per the given information in the question,

Mass of the object, m = 5 kg

Acceleration, a = 2 m/s²

Distance, d = 10 m

W = f × d

W = m × a × d

W = 5 × 2 × 10

W = 100 Nm

The girl's reference frame must be moving with the same speed as the plane.

If an observer is stationary and he watches a car moving he can observe that the car has a momentum and is moving with certain speed. But if the observer is in the car or moving with same speed, the car does not appear to move away form the observer. Likewise, two observers moving with different speed will have different observation about the same car.

Similarly, if the girl describes the plane is not moving that means either she is in the plane or moving with the same speed along with the plane.

Explanation:

The total amount of energy in two cells combined will be:

[tex]Total\ Energy = 40000\ J + 40000\ J\\Total\ Energy = 80000\ J\\[/tex]

Now, we calculate the power of the batteries:
