As a experiment you could use is The affect of light in plants. A study He can do is maybe about Gravity affects and how it works on weight. Also you can do a all time favorite the Mentos and Diet Coke Experiment.
Hopefully one of these ideas will inspire you!
electromagnetic spectrum is consisting of many frequency range which is from gamma rays to radio waves
they are of various wavelength and different energy levels
minimum wavelength will occurs at Gamma rays
and maximum wavelength at Radio waves
the list of increasing order of wavelength is as following
Gamma rays < X rays < Ultraviolet < Visible Light < Infrared Waves < Radio Waves
so least to maximum order is
1. Gamma rays
2. X rays
3 Ultraviolet
4 Visible light
5 Infrared waves
6 Radio waves
Answer:
2m/s²
Explanation:
acceleration is the rate of change of velocity
for velocity to reach 10m/s in 5s,
acceleration= 10/5
=2
It will consume 60wh=0.06kwh
The original vertical velocity = 0 (because the stone was dropped).
Assume that air resistance may be ignored.
Let x = the distance the stone drops in time t.
Then
x = 0*t + (1/2)*(9.8 m/s²)*(t s)²
= 4.9t² m
The height of the stone above ground is
h(t) = 900 - 4.9t² m
Answer: h(t) = 900 - 4.9t²
