The answer is C) a rolling bowling ball because kinetic energy is the energy of movement and potential energy is the energies of the others, since there are not in movement. i hope this helps.
Answer:
b. 0.75 mm
Explanation:
The distance between antinodes d is half the wavelength 
. We can obtain the wavelength with the formula 
, where f is the frequency given (
) and v is the speed of sound in body tissues (v=1540m/s), so putting all together we have:
which is very close to the 0.75mm option.
Answer:
1.41s
5.95m/s
0.2746m
Explanation:
The time period
T = 1/f
= 1/0.709s
= 1.41 seconds
We have
T = 2π√l/g
T² = 4π²l/g
g = 4π²l/T²
g = 4x3.14²x0.300/1.41²
g = 5.95m/s² this is the acceleration due to gravity.
Then the time period of the glide
T2 = 2π√m/k
Length of pendulum = l
Time period T
T2 = 2π√l/g
Then T1 = T2
2π√m/k = 2π√l/g
M/k = l/g
L = g.m/k
L = 5.95x0.450/9.75
L = 0.2746
This must be the length of the simple pendulum
Vs = 34m/s
I don’t have an explanation my apologies.
