Answer:
energy is transformed when your rubbing your hands together because of the mechanical energy of your hands moving together creates both sound energy and heat energy from the friction and chemical energy is created when the atoms and molecules in your hands interact
Explanation:
Answer:
A
Explanation:
More potential energy equals more kinetic
Answer:
weight = 25*10 =250 N
Explanation:
g must be given in units of m/s^2
The weight of any type of body will be the product of his mass by the gravity
where:
m =mass [kg]
F = force [N] or [kg*m/s^2]
g = acceleration [m/s^2]
The charge on the conductor is +24 μC, since the charge is positive, same amount of charge but it will be negative.
That is - 24 μC.
To know the number of electrons, we know that the charge of an electron =
-1.6 * 10^-19 C.
= - 24 μC / (-1.6 * 10^-19 C)
= (-24 * 10^-6) / (-1.6 * 10^-19 C) Use your calculator
= 15 * 10^13
= 1.5 * 10 ^14 Electrons.
here our distance is given with respect to ticket booth
initial distance is given 50 m from the booth
So our initial position is
now after this finally we reach at final position
now change in position is given as
<em>so change in position is 45 m in magnitude and since we are coming closer to the booth so its coming negative in sign</em>
