Answer:
"where crests and troughs have their maxima at the same time"
Crests and troughs are 180 deg out of phase and when they have their maxima at the same time and place, their net contribution will be zero"
I think it's A Tsunami. Or an Earthquake
Answer:
s = 27 m
Explanation:
given,
acceleration of the car, a = 6 m/s²
time of the travel, t = 3 s
final speed of the car, v = 0 m/s
using equation of motion
v = u + a t
0 = u - 6 x 3
u = 18 m/s
initial speed of the car = 18 m/s
Again using equation of motion
v² = u² + 2 a s
0 = 18² - 2 x 6 x s
12 s = 324
s = 27 m
Distance travel by the car is equal to 27 m.
Answer:
The answer is A.
Explanation:
The graph would show the unit rate otherwise known as a ratio
According to the conservation of energy
- Potential energy at any given instance is equal to the Kinetic energy as energy can neither be created nor be destroyed
Mass is 2kg=m
#A
h=5m
PE
Now
- KE=98J
- 1/2mv²=98J
- 1/2×2v²=98J
- v²=98J
- v=√98
- v=9.4m/s
#B
h=3.2m
PE:-
Now
- KE=62.7J
- 1/2mv²=62.7
- v²=62.7
- v=√62.7
- v=7.9m/s
#C
h=2m
PE
Now
