Answer:
B) Angular velocity
Explanation:
The equivalent of Newton's second law for rotational motions is
where
is the net torque on a system
I is the moment of inertia
is the angular acceleration
From the formula, we observe that if a constant net torque (=different from zero) is applied to an object, than the angular acceleration of the object 
is non-zero and constant.
But angular acceleration is defined as the rate of change of the angular velocity, 
:
so, a non-zero angular acceleration means that the angular velocity is changing, so the correct answer is B.
Answer:
i think the planet is Uranus
Running because kinetic energey is the engery created by motion
Light year is the unit of distance. It is the distance that an object travels in one year with the speed of light.
In short, Your Answer would be "Distance"
Hope this helps!
Answer:
F = 196 N
Explanation:
For this exercise we will use Newton's second law, we define a reference system with the x axis in the direction of movement of the stones and the y axis vertically
Y axis
N- W = 0
N = mg
X axis
F -fr = ma
In this case, they ask us for the force to keep moving, so the stones go at constant speed, which implies that the acceleration is zero.
F- fr = 0
F = fr
the friction force has the equation
fr = μ N
fr = μ mg
we substitute
F = μ mg
let's calculate
F = 0.80 9.8 25
F = 196 N
