Answer: They have different rigidities.
Explanation:
B.because electromagnetic waves transmit energy without compressing the particles of the medium
Answer:
gather the data needed to make the forecast
Answer:
Speed of the electron will be
Explanation:
We have given that charge on electron
Mass of electron
Potential difference =
Now according to energy conservation
Given:
m = 70 kg, mass
F = 650 N, force
t = 0.8 s, time
Calculate the acceleration.
a = F/m = (650 N)/(70 kg)
= 9.2857 m/s²
Because the initial velocity is zero, the final velocity (after time 0.8 s) is
v = a*t = (9.2857 m/s²)*(0.8 s)
= 7.43 m/s
Answer: 7.43 m/s (nearest hundredth)
