Answer:
Balancing on one finger.
Tossing between hands.
Using a different body part.
Building a tower.
Throwing it high in the air.
Flipping it over.
Switching between fingers.
Going behind the back.
Explanation:
Just stuff I used to do ^^
That's the wave's ' period '.
It's the reciprocal of the wave's frequency.
Well, i would tell the kid that light is electromagnetic radiation which
is visible. The frequency and wavelength is just right so the radiation
becomes visible, and that visible radiation goes away from the star and
reaches earth
It also depends on the age of the child and the comprehension level
Explanation :
Simple machines makes our work easier. Lever is one of the simple machine which consists of rigid rod that is pivoted at a fixed support called as Fulcrum.
There are three classes of lever.
Class 1 : In this type of class, fulcrum is placed in between effort and load. Hence the movement of load is in reverse direction of the movement of effort. (fig 1)
Class 2 : In this type of, the load is between the effort and the fulcrum. Hence, the movement of load is in same direction as that of the effort. (fig 2)
Class 3 : In this type of lever the effort between the load and the fulcrum. Hence, both the effort and load are in same direction. (fig 3)
Hence, when the position of fulcrum is modified the effort force changes.
Answer:
Sure, the frequency is 500Hz
Explanation:
Sure, the frequency can be calculated. The needed information which is the speed and wavelength of the wave are known.
Wavelength is the distance between two successive crest and trough of a wave.
Using the relationship
V = fλ
V is the speed of wave
F is the frequency
λ is the wavelength
f = v/λ
Given v = 100m/s, λ = 10cm/0.5 = 20cm
20cm = 0.2m
f = 100/0.2
f = 500Hertz
