Answer:
The speed of the wave is 3 m/s.
Explanation:
Given that,
Number of waves = 6
Time = 8.0 s
Successive crests
We need to calculate the frequency
Using formula of frequency
Put the value into the formula
We need to calculate the speed of the wave
Using formula of speed
Put the value into the formula
Hence, The speed of the wave is 3 m/s.
An animal might use more than one type of clue to find its way due to change in the way one mechanism used to work.
Different animals have different senses heightened, that lets them use different mechanisms to navigate. Some of the mechanism include remembering landmarks, solar navigation, star navigation, magnetoreception, olfaction, gravity receptors etc.
For example, a bird using landmark to navigate will find it hard to navigate in the same way again if the landmark has been changed. So it has to depend on other senses such as olfaction or magnetoreception to navigate.
Therefore, an animal might use more than one type of clue to find its way due to change in the way one mechanism used to work.

Answer:
static electricity is built up of charges on an object
Answer:
4.9
Explanation:
Velocity half second before maximum height = Velocity half second after maximum height (Return journey)
For downward journey :
Initial velocity u=0 m/s
We have g=9.8 m/s
Time t= ½s
s
Thus velocity after half second v=u+gt
v=0+9.8× ½ =4.9m/s
Answer:
Explanation:
Displacement involves direction and distance. In this case, the deer has walked a distance of 17 + 12 = 29m but because of the South-then-North direction, the net displacement is only 17-12 = 5m.
So the answer is A) 5.0 m, 29.0 m
