Answer:
Gravitational potential energy,
Explanation:
Mass of an Egyptian pyramid,
It is placed 19 m above the surrounding ground, h = 19 m
We need to find the gravitational potential energy store in the pyramid. This energy is possessed by an object due to its position. It is given by :
So, the gravitational potential energy store in the pyramid is . Hence, this is the required solution.
The answer is d) The 1.5 kg ball because it has more momentum.
Momentum = Impulse = Mass + Velocity
= 2 * 10 = 20 kg*m/s
= 1.5 * 20 = 30 kg*m/s
hence the 1.5 kg ball has greater momentum and impulse.

According to the statement of OHM's Law,
The current in an electric circuit is directly proportional to the voltage across that circuit. This means, larger the voltage , more will be the current flow. Mathematically this can be stated as:
I = V/R
Here 1/R is the constant of proportionality and R represents the Resistance of the circuit.
This equation is also stated in texts as:
V = IR
So, the correct answer is option A. Voltage

F=uR
where U is constant of friction and R=mg
F= mgcos 36
