As given the formula of range is

now for the maximum range


now for half of this maximum range we will have


now from above we have

so two possible values for above is given as

so above two angle we will have half of maximum range
In physics<span>, a </span>force<span> is said to do </span>work if, when acting, there is a displacement of the point of application in the direction of the force. For example, when a ball is held above the ground and then dropped, the work done on the ball as it falls is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement). so in the proble, <span>She does NO work since the force she applies to the case is vertical and the direction of motion is horizontal. Work is the force times the parallel distance</span>
Answer:
pretty sure it's true....
Answer:

Explanation:
As we know that EMF is induced in a closed conducting loop if the flux linked with the loop is changing with time
So we can say

now we have

here since magnetic field is constant so we have

now we have


now we have
