A mechanical wave moves through all matter
Answer:
For carbon 12
ΔV1 = 2265.31 V
ΔV2 = 362.5 V
For carbon 14
ΔV1 = 1941.7 V
ΔV2 = 310.67 V
Explanation:
The complete explanations are given in the attachment below. The formulae for the accelerating potential ΔV1 and ΔV2 are derived and the necessary parameters are substituted into the derived equations.
Answer:

Explanation:
When a suspended string makes and angle of 25 degree while aircraft is accelerating on runway then we can use force equations to find the acceleration of the aircraft
So we will have


now from above two equations we have



now if it took 18 s to take off we can have final speed of the aircraft given by



Answer:
1. I notice nothing because is no picture it probably didnt work
2. idk
Answer:
the right answer is reflection
