The wheel and axle is a simple machine that reduces the friction involved in moving an object, making the object easier to transport. ... Once the object is moving, the force of friction opposes the force exerted on the object. The wheel and axle makes this easier by reducing the friction involved in moving an object.
In addition to reducing friction, a wheel and axle can also serve as a force multiplier, according to Science Quest from Wiley. If a wheel is attached to an axle, and a force is used to turn the wheel, the rotational force, or torque, on the axle is much greater than the force applied to the rim of the wheel.
Answer:
I think the answer is b but i cannot confirm cuz this is a challenging question
Answer:
Radius in mm will be 4.425 mm
Explanation:
We have given given escape speed of earth is equal to speed of the light as
Gravitational constant
Mass of the earth
We have to find the radius of the earth
We know that escape speed is
So
Squaring both side
So radius in mm will be 4.425 mm
