Answer:
It Crashed Because it was speeding LOL
Explanation:
It was speeding so cops put spices and truck Crashed
Answer: The dog is pull the stick away from the boys hand
the boy is also pulling if the boy lets go of the stick the dog will fall due to law of action and reaction
The man is pushing the horse cart up the hill to do so he has to apply force
Explanation:
<h3><u>Answer;</u></h3>
Position A: Maximum potential and minimum kinetic energy
Position B: losing potential and gaining kinetic
Position C: Maximum kinetic and minimum potential energy.
Position D: is losing kinetic and gaining potential
Position E: Maximum potential and minimum kinetic energy.
<h3><u>Explanation;</u></h3>
- Position A is a point of maximum potential energy and minimum kinetic energy since it is the highest point of the pendulum.
- Position B, which is half way between A and C, the ball is losing potential energy and gaining kinetic energy. This occurs as the ball descends from the highest position to the lower position thus looses potential energy and gains kinetic energy.
- Position C is the point of maximum kinetic energy and minimum potential energy. Because this is the lowest point of the pendulum and a point where the ball has maximum velocity.
- At position D which is half way between C and E, the potential energy is increasing as the kinetic energy is decreasing. At this point the ball has half of its maximum potential energy.
- At position E, he potential energy of the pendulum reaches its maximum value and is neither increasing nor decreasing at that point.
Answer:
UV light is more powerful as it has greater energy.
Explanation:
The energy propagated by electromagnetic waves ( light ) through vacuum or medium is known as electromagnetic radiation.
The frequency/wavelength range of electromagnetic radiation is known as electromagnetic spectrum. The electromagnetic spectrum ranging from gamma ray to radio waves.
Frequency range of UV light = ( 8 x 10¹⁴ to 3 x 10¹⁶ ) Hz
Frequency range of Microwaves = ( 300 x 10⁶ to 300 x 10⁹ ) Hz
Ratio of UV light to Microwaves = (
to 
)
= ( 2.66 x 10⁶ to 1 x 10⁸ )
Energy of electromagnetic radiation is given by the relation:
E = hν
Here h is plank's constant and ν is frequency.
UV light is more powerful than Microwaves as frequency of UV light is greater than frequency of microwaves. Thus, by the above equation, the energy of UV light is more than energy of Microwaves.
