Which of the following describes what occurs when energy is transferred and work is being done on an object?

1 answer:

5 0

<span>The object moves.. since by definition, work is done when a force is applied and a displacement is produced. It is not D because by rule of physics, the amount of work done is equal to the energy gained, always.</span>

Answer:

$\theta = 15^o \: or\: 75^o$

Explanation:

As we know that the formula of range is given as

$R = \frac{v^2sin2\theta}{g}$

now we know that

maximum value of the range of the projectile is given as

$R_{max} = \frac{v^2}{g}$

now we need to find such angles for which the range is half the maximum value

so we will have

$\frac{R}{2} = \frac{v^2}{2g} = \frac{v^2sin(2\theta)}{g}$

$sin(2\theta) = \frac{1}{2}$

$2\theta = 30 or 150$

$\theta = 15^o \: or\: 75^o$
