because it will help it go and funcion more
Explanation:
If a mountain goat starts a rock slide and the rocks crash down the slope 100 m. If the rocks reach the bottom in 5 s, then the acceleration of the rock would be 8 meters/second².
<h3>What is acceleration?</h3>
The rate of change of the velocity with respect to time is known as the acceleration of the object.
As given in the problem a mountain goat starts a rock slide and the rocks crash down the slope 100 m. If the rocks reach the bottom in 5 s,
initial velocity of rock = 0 m/s
displacement = 100 meters
time = 5 seconds
s = ut + 0.5at²
100 = 0 + 12.5a
a = 100/12.5
= 8 meters/second²
Thus, the acceleration of the rock would be 8 meters/second².

Lower. Water expands on lower temperatures, meaning less molecules in 1 m3, thus making it less dense
The bulbs are in parallel.
The picture doesn't show enough of the circuit to tell
whether it's also open or shorted. It may be either, or
it may be neither.
Answer:Sound travel faster in warm room.
Explanation:The speed of sound depends on the temperature of the medium. Mathematically, the relation between the speed of the sound and the temperature is give by:v=
is the ratio of the specific heats
R is the gas constant
T is the temperature of the medium
We know that the temperature of the warm room is more as compared to the cold room.
So, it is clear that the sound travel faster in a warm room. The particles move faster when the temperature is high.
