Answer:

<h3>U_{2}=4U_{1}</h3><h3>Explanation:</h3>

Let U1 and U2 be the gravitational potential energy of the first and second stone  respectively.

U1 is given by:

U_1 = (m)gh\\

and U2 is given by:

U_2 = (4m)gh  

therefore, comparing the energies we have:

\frac{U_2}{U_1} = \frac{(4m)gh}{(m)gh}= 4

therefore:

U_2=4U_1

When a transformer is step down then
Vera_Pavlovna [14]

Answer:

Hey!

Your answer should be D!

Explanation:

In a transformer Np / Ns is called the voltage ratio. If Ns is less than Np then Vs is less than Vp. This is called a step-down transformer as the voltage is reduced.

The initial momentum and the vertical and horizontal component
tamaranim1 [39]
Momentum = mass * velocity

p = mv

p = 1.5 kg * 40 ms^-1

p = 60 kgm/s

To find components of a vector:

px = p * cos(theta)
px = 60 * cos(30)
px = 51.96 = 52 (rounded to two significant digits)

py = p * sin(theta)
py = 60 * sin(30)
py = 30

He initial momentum is 60kgm/s
The horizontal component is 52 kgm/s
The vertical component is 30 kgm/s
