When an equation is used to calculate the amount of product that will form during a reaction, then the value obtained is called

bekas [8.4K]

This would be the theoretical yield. This is the amount of product that should be obtained in the end of a reaction, given that none of the reactants are wasted in the creation of the product. This is unlikely to be exactly obtained, however, due to waste products being formed in the process.

Selina drops a golf ball down a deep well. The ball falls with only the force of gravity acting on it. Without any air resistanc

ss7ja [257]

Answer: A. constant

Without any air resistance, as the golf ball falls into the well, its speed is constant.

Explanation:

Given that when the ball is released,there is no air resistance acting on ball. So the ball is freely falling. 

The only force acting on the freely falling body is the gravitational force pulling the body towards the centre of the earth.Here the only acceleration acting on the body is the acceleration due to gravity.

The acceleration due to gravity is $9.8 m/s^2$ . so through out the journey of the ball,the acceleration is $9.8 m/s^2$ . So as the acceleration is constant, the speed is also constant.
