Answer:bowling ball has greater kinetic energy
Explanation:
Kinetic energy of bowling ball:
mass=m=5kg
Velocity=v=6m/s
Kinetic energy =ke
Ke=0.5 x m x v x v
Ke=0.5 x 5 x 6 x 6
Ke=90J
Kinetic energy of ship:
mass=m=120000kg
velocity=v=0.02m/s
Ke=0.5 x m x v x v
Ke=0.5 x 120000 x 0.02 x 0.02
Ke=24J
Answer:
10 mph
Explanation:
- Exceeding speed limit is one of the major causes of road accident.
- Crash severity increases with the speed of the vehicle at impact.
- The probability of death, disfigurement, or debilitating injury grows with higher speed at impact.
The above consequences double for every 10 mph over
50 mph that a vehicle travels.
The radiation detector that uses detection of flashes of light is a <u>scintillation counter.</u>
<h3>What is a scintillation counter?</h3>
A scintillation counter detects and measures ionizing radiation by using the excitation action of incoming radiation on a scintillating substance and detecting the light pulses that arise.
One of the most critical considerations for anyone who operate with or near radiation is being aware of the amounts of radiation present.
This is generally performed through the use of several types of radiation detectors.
The radiation detector that uses detection of flashes of light is a scintillation counter.
Hence,scintillation counter is the correct answer.
