Thought Experiment: A monkey escapes from a zoo and climbs a tree. After failing to entice the monkey down, a zookeeper fires a
Andreyy89

Explanation:

When bullet is shot towards the monkey then let say the distance of monkey from the bullet is "d"

so we can find the time to reach the bullet to the monkey

t = \frac{d}{vcos\theta}

Now similarly we can find the vertical displacement of the bullet in the same time

\Delta y = vsin\theta t - \frac{1}{2}gt^2

\Delta y = v sin\theta (\frac{d}{vcos\theta}) - \frac{1}{2}gt^2

so it is given as

\Delta y = d tan\theta - \frac{1}{2}gt^2

here if the monkey is initially at height H above the ground at given angle then we can say

H = dtan\theta

so we can say that

\Delta y = H - \frac{1}{2}gt^2

So if at the same time monkey will fall down then the height of monkey from ground after time "t" is given as

\Delta y = H - \frac{1}{2}gt^2

so here bullet will hit the monkey as both monkey and bullet are at same position.

The emf of a battery is equal to its terminal potential difference: A) under all conditions B) only when the battery is being ch
velikii [3]

Answer:

option (C)

Explanation:

EMF stand for electro motive force. the emf of a battery is the potential between the two electrodes when it is not use in the circuit.

The terminal potential difference is the potential difference between the electrodes of a cell when it is in use.

EMF is only when the current is very large in the battery.

Why aren't the electrons counted in the mass of an atom?
Radda [10]

Answer:

Explanation:

The mass of an electron is small compared to the neutron and proton, so it's negligible. It's like adding zero to a number.
