The Celcius and kelvin scale are related unit for unit. One degree unit on the Celcius scale is equivalent to one degree unit on the kelvin scale. The only difference between these two scales is the zero point.
Answer:
thick wire and cold temperatures
A. W
Explanation:
The wave that would be produced by the interaction of the two waves shown in the diagram is wave W.
There is no wave in the diagram W.
This type of interference is known as destructive interference.
- Destructive interference occurs when two waves out of phase comes together.
- In this way, they cancel out each other and are terminated.
- If the two waves are in phase, they will reinforce one another.
- When waves reinforce one another, a constructive interference has occurred.

Explanation:
Given
Distance putty has to travel is 3.5 m
The initial speed of putty is 9.50 m/s
Using equation of motion to determine the velocity of putty just before it hits ceiling
So, the velocity of putty just before hitting is
