Una rueda desde reposo y rot con aceleración angular de 12.0rad/s en 3.00s. Encuentre la magnitud de la aceleración angular de la rueda y b) el ángulo en radianes que gira en este tiempo

nah.   i'm just sleepy.

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
