The answer is the second one, because in exothermic reactions energy is released.
Answer:
0.026 meter
Explanation:
using distance time equation to determine the time for the puck to move 16.5 meters.
distance 'd' = velocity'v' x time't'
16.5 = 44 x t
t =0.375 second
Here momentum is conserved. Since both objects are initially at rest, the initial momentum is 0.
Next is to determine the puck’s momentum.
Momemtum 'p' = m x v => 0.15 x 44 = 6.6kg⋅m/s
The player momentum is -6.6kg⋅m/s .
In order to determine the player’s velocity, we'll use p=mv
-6.6 = 94v
v= -0.0702 m/s
The above negative sign represents that the player is moving in the opposite direction of the puck.
Lastly, how far does the player recoil in the time it takes the puck to reach the goal 16.5 m away?
d = v x t = 0.0702 x 0.375= 0.026 meter
Answer: (A) a back-and-forth motion on the surface of the earth
Explanation:
Earthquake generates seismic waves which are longitudinal waves.Longitudinal waves travel parallel in the direction of transfer of energy. Meaning that they travel in back and forth motion.
Longitudinal waves consist of compressions and rarefactions. When compressions occur when particles are close together and are regions of high pressure. Whereas, rarefactions occur when particles are further apart and regions of low pressure.
The answer is C since the higher up you go the colder it gets which is why Linda will experience colder climates.
Answer:
Good question
Explanation:
The reason is that walls are made up of more than just atoms. Walls are built up from many things, so with this being said we cannot walk through the walls
PPs why do or should anyone want to walk through walls?
