Answer:
v = 6.72 m/s
Explanation:
Given that,
Vertical height, h = 2.31 m
We need to find the speed at the bottom of the slide. Let the speed be v. We can find it using the conservation of energy such that,
Put all the values,
So, her speed at the bottom of the slide is equal to 6.72 m/s.
Answer:
3 x 10^ 8 m/s
Explanation:
Speed of wave = wavelength/time period
= 30000/0.0001
= 300000000 m/s
Answer:
19.29 m/s
Explanation:
Apply the conservation of linear momentum in north-south direction:
Apply the conservation of linear momentum in east-west direction:
Dividing the two equations:
Thus, the speed of the eagle immediately after it catches its prey is 19.29 m/s.
Answer:
Up And Down
Explanation:
In this case, the particles of the medium move parallel to the direction that the pulse moves. This type of wave is a longitudinal wave. Longitudinal waves are always characterized by particle motion being parallel to wave motion.
