Answer: The acceleration that is directed radially towards the center of the circle having a magnitude equal to the square of the speed of the body along the curve is divided by the total distance from the center of the circle to the moving body.
Explanation:
Yw and mark me brainiest
Answer: -1.27 m/s^2
Explanation:
a = - V^2 / 2x
a = -(25^2) / 2 x (246) = 1.27 m/ s^2
Therefore the linear acceleration of the wheel is - 1.27 m/s^2
Answer:
c. Both forces have equal magnitudes.
Explanation:
According to Newton´s 3rd Law, the force exerted by a body on another one , is equal and opposite to the one that the second object exerts on the first one.
This does not depend on the masses of the objects, so it doesn´t matter that m₁ be greater than m₂.
As examples of this, we can mention the gravity force, the electrostatic force, the normal force, etc.
So, in this case, taking into account only the magnitudes, we can say:
F₁₂ = F₂₁
The answer is "heat transfer."
