Oksana_A [137]

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.

Francesca, who likes physics experiments, dangles her watch from a thin piece of string while the jetliner she is in takes off f
Tom [10]

Answer:

v_f = 82.3 m/s

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

T sin\theta = ma

T cos\theta = mg

now from above two equations we have

a = g tan\theta

a = (9.81) tan25

a = 4.57 m/s^2

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

v_f - v_i = at

v_f - 0 = (4.57)(18)

v_f = 82.3 m/s
