Answer:
A force is any interaction that causes a mass to change its velocity (accelerate).
Weight is a special case of force. Weight is when a mass is accelerated by gravity.
Answer:
1. Count the atoms of each element in the reactants and the products.
2. Use coefficients; place them in front of the compounds as needed.
Explanation:
Answer:
a)
Explanation:
a) Let consider that disk accelerates and decelerates at constant rate. The expression for angular acceleration and deceleration are, respectively:
Acceleration
Deceleration
Since angular acceleration and deceleration have same magnitude but opposite sign. Let is find the maximum allowed angular speed from maximum allowed centripetal acceleration:
Maximum magnitude of acceleration/deceleration is:
The least time require for rotation is:
