6 months with no sunrise and the other 6 without a sunset, at some places on Earth, are the result of the orientation of Earth's axis.
FORMULA:
ANSWER:
We are given with mass of car 394kg and velocity of car 15m/s.
Plugging the respective value,
- K.E. = 1/2 × 394 × 15²
- K.E. = 197 × 225
- K.E. = 44,325J
<h2>Right answer: 8 m</h2><h2 />
When two waves propagate in the same medium, in the same or opposite direction, they <u>overlap (superposition</u>), that is, the individual waves are added producing a resultant wave. When the superposition of the waves occurs, they continue to advance after the encounter happens, conserving their properties, such as amplitude, frequency, wavelength and speed.
In this case, we have two water waves travelling in opposite directions with <u>differente amplitude</u>, when both waves encounter each other, at that moment the amplitude of the resultant wave is the sum of both, that is:
5m + 3m = 8 m
Therefore, the correct option is D
Sound waves travel through the air, liquids, and solids. they transfer energy from the source of the sound to its surroundings
Answer:
Given mass = 2kg, height = 1.2m,g = 9.8.
We know that Work done W = FD
= > W = (mg)(D)
= > W = (2 * 9.8)(1.2)
= > W = 23.52 Joules.
