Assuming the system is in equilibrium, calculate the missing distance d
Answers
Answer:
d=3.4m
Explanation:
From principle of equilibrium,
TOTAL C.WISE MOMENTS = TOTAL A.C.WISE
10N×d = 2N ×2m + 6N×5m
10Nd =4Nm+ 30Nm
10Nd=34Nm
10N 10N
d=3.4m
The system is in equilibrium, calculate the missing distance d=3.4 m.
What is Displacement?Displacement is defined as the change in position of an object. It is a vector quantity and has a direction and magnitude.
From principle of equilibrium,
TOTAL C.WISE MOMENTS = TOTAL A.C.WISE
10 N×d = 2 N ×2 m + 6 N×5 m
10 Nd = 4 N m+ 30 N m
10 Nd = 34 N m
d = 3.4 m

A wave vibrates up and down 22 cycles in 7 seconds with a wave speed of 57. Calculate the
wavelength. (Round to the 2nd number after the decimal)
Answers
Answer:
18.14m
Explanation:
Given parameters:
Frequency = [tex]\frac{22}{7}[/tex]cycles/s
Speed of wave = 57m/s
Unknown:
Wavelength = ?
Solution:
The speed of a wave is related to frequency and wavelength using the expression below;
V = f x λ
V is the speed of the wave
f is the frequency
λ is the wavelength
Insert the parameters and find λ;
57 = [tex]\frac{22}{7}[/tex] x λ
λ = 57 x [tex]\frac{7}{22}[/tex] = 18.14m

When a 3.0 kg mass is hung from a vertical massless spring, the spring is stretched 40 cm. What is the spring constant of the spring?
Answers
Answer:
0.74 N/cm
Explanation:
The following data were obtained from the question:
Mass (m) = 3 Kg
Extention (e) = 40 cm
Spring constant (K) =?
Next, we shall determine the force exerted on the spring.
This can be obtained as follow:
Mass (m) = 3 Kg
Acceleration due to gravity (g) = 9.8 m/s²
Force (F) =?
F = mg
F = 3 × 9.8
F = 29.4 N
Finally, we shall determine the spring constant of the spring. This can be obtained as follow:
Extention (e) = 40 cm
Force (F) = 29.4 N
Spring constant (K) =?
F = Ke
29.4 = K × 40
Divide both side by 40
K = 29.4 / 40
K = 0.74 N/cm
Therefore, the spring constant of the spring is 0.74 N/cm

A net force of 1 newton causes an object to accelerate at a rate of 5.0 meters per second per second. What is the mass of the object?
Answers
The mass of the object is equal to 0.2 Kg when it accelerates at 5.0 m/s².
What is acceleration?Acceleration of an object can be defined as the rate at which the object changes its velocity w.r.t. time. The acceleration can be expressed as the second derivative of position w.r.t. time and is a vector parameter.
The force exerted on an object is equal to the multiplication of the mass (m) and acceleration (a) according to Newton's 2nd law of motion.
F = ma
And, a = F/m
The mass and acceleration have an inverse relationship.
Given, the net force acting on an object, F = 1 N
The object is accelerating at a rate, a = 5.0 m/s²
The mass of the object can be determined by using the given information as follows:
m = F/a
m = 1/ 5.0
m = 0.2 Kg
Therefore, the mass of the object is equal to 0.2 Kg.

A baseball bat is a lever. Which of the following explains how a baseball bat differs from a lever like a pry bar?
Answers
Complete question is;
A baseball bat is a lever. Which of the following explains how a baseball bat differs from a lever like a pry bar?
A) In a baseball bat, effort force is smaller and is applied over a large distance, while the resistance force is smaller and is applied over a long distance.
B) In a baseball bat, effort force is smaller and is applied over a large distance, while the resistance force is smaller and is applied over a short distance.
C) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a long distance.
D) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a short distance.
Answer:
C) In a baseball bat, effort force is larger and is applied over a short distance, while the resistance force is smaller and is applied over a long distance.
Explanation:
The correct answer is option C. This is because unlike in a pry bar, the effort force when swinging a baseball bat is larger and it is applied over a short distance; and in return the resisting force is smaller and it's applied over a long distance.

Black widow (m=57000 g) shovels snow, holding the shovel at a 40 degree angle above the ground. If she uses a constant force of 180. N and pushes the snow 5.00 m. How much work does she do on the snow?
Answers
Answer:
She does a work of 689.44 J in the snow.
Explanation:
A force is said to do work when it alters the state of motion of a body. The work of the force on that body will be equivalent to the energy needed to move it.
In other words, Work is a form of energy transmission between bodies. In order to carry out work, a force must be exerted on a body and it must move.
The work is equal to the product of the force times the distance and the cosine of the angle that exists between the direction of the force and the direction that the moving point or object travels:
W= F*d* cos Ф
Work W is measured in joules (J), force is measured in newtons (N), and displacement in meters (m).
In this case:
F= 180 Nd=5 mФ= 40 degreesReplacing:
W= 180 N*5 m* cos 40
Solving:
W= 689.44 J
She does a work of 689.44 J in the snow.

Its velocity remains constant.
It covers unequal distances in equal intervals of time.
Its velocity changes
None of the above
Answers
Answer:
Its velocity changes
Explanation:
When the truck changes direction, its velocity changes.
Velocity is a vector quantity that specifies the magnitude of motion and direction it is taking.
When direction changes, the velocity of a body will also change. This is unlike speed which is a scalar quantity.
Velocity is the displacement divided by time taken.

Erica (39 kg ) and Danny (46 kg ) are bouncing on a trampoline. Just as Erica reaches the high point of her bounce, Danny is moving upward past her at 4.6 m/s . At that instant he grabs hold of her.
Answers
Answer:
V = 2.79 m/s
Explanation:
Momentum before = momentum after
Erica's momentum = 0
Danny momentum = 49 kg * 4.9 m/s = 240.1 kg-m/s
240.1 + 0 = (37 + 49) kg * V
86 V = 240.1
V = 2.79 m/s
