Contact- Frictional force (Needs to be rubbing against the toy for it to happen)
Non Contact- Probably…? Gravitational force (Doesn’t need to be touching for it to happen)
Answer:
1 / f = 1 / p + 1 / q
Explanation:
For this exercise we will use two methods, an analytical method which is to use the constructor equation
1 / f = 1 / p + 1 / q
where f is the focal length, positive for converging lenses and negative for diverging lenses, p and q are the distance to the object and the image respectively
m = h’/ h = - q / p
where m is the magnification, h ’and h are the height of the image and the object.
We will also use a graphical method, where three rays will be traded
1) A ray that passes through the center of the lens and should not
2) a ray that passes through the focal length and comes out parallel to the lens
3) A ray that is horizontal and comes out through the focal from the other side
for this second method see the attachment
The torque value is 560 Nm, so the result does not depend on the value of Ф.
Given:
Mass=80.0 g
Radius=20.0 cm
Magnetic field=0.35T
In a magnetic field, a loop of current-carrying wire will experience the following torque:
τ=μ×Β
Here, is the μ magnetic moment and Β is the magnetic field.
τ= 1600 × 0.35 T
τ= 560 Nm
<h3>
What is torque and its SI unit?</h3>
The rotating equivalent of force is torque. It is also known as the moment, moment of force, rotating force, or turning effect depending on the field of research. It serves as an example of how a force can alter a body's rotational motion.
The Newton-metre, or kgm2sec-2, is the SI unit for torque. How did we get to this point? Considering the equation Torque = Force X Distance Torque is measured in newton-meters, whereas distance is measured in meters and force is measured in newtons.

The actual mechanical advantage, the velocity ratio, and the length of the slope if the height of the slope is mathematically given as
<h3>What are the actual mechanical advantage, the velocity ratio, and the length of the slope if the height of the slope is 10 m?</h3>
Question Parameters:
A block of weight 5000 N is pushed up a slope by a force of 250 N.
Generally, the equation for the actual mechanical advantage is mathematically given as
A=Fout/Fin
A=5000/250
A=20
b)
the velocity ratio is given by the distance moved by the effort divided by the distance moved by the load
Therefore
VR=250/5000
VR=0.05
c)
the length of the slope if the height of the slope is 10 m
Assume the slope is at an angle of 30
Hence
sin 30=10/x
x=20m

Answer:
Inertia
Explanation:
The term for the tendency is inertia.
<em>The inertia of a body is the tendency of the body to remain unmoved when at rest and the tendency to keep moving when in motion. In other words, it is the tendency of a body to remain in a state of rest or motion. </em>
A static body will remain in a state of perpetual rest if no force acts on it and a moving body will keep moving in the same direction if no force acts on it. The force that needs to be overcome in order to change the state of the object is otherwise known as inertia force.
