The atom becomes positively charged.
EXPLANATION :
When all the electrons are removed from the atom, the atom contains only protons and neutrons. The neutron is a neutral nucleon. ...
Hence, the correct answer is that atom will be positively charged.
Answer:
4.25 m/s
Explanation:
Force, F = 22 N
Time, t = 0.029 s
mass, m = 0.15 kg
initial velocity of the cue ball, u = 0
Let v be the final velocity of the cue ball.
Use newton's second law
Force = rate of change on momentum
F = m (v - u) / t
22 = 0.15 ( v - 0) / 0.029
v = 4.25 m/s
Thus, the velocity of cue ball after being struck is 4.25 m/s.
Answer:
Explanation:
The Planck Eistein relation, states that the energy of a photon is proportional to its frequency:
h is the Plank constant.The frequency of a photon is defined as the speed of light over its wavelength:
Replacing (2) in (1):
Answer:
2 h
Explanation:
Velocity =Distance/time ⇒ time = distance/speed
= 1440/720
= 2 h
Answer: I only have the answer for A, but still, the answer is 20.07.
- Explanation: Because the number ends in a 15, round to the nearest tenth which is 20. So now the number is 5420.
- To get the Watts (W) you have to take 5420 and divide it by the time in seconds. 4.5 minutes in seconds is 270, so 5420 divided by 270 equals 20.07.
- So 20.07 is the answer.
