Answer:
This is called displacement.
Everything in or on water pushes some water aside, even if it’s just a little bit. This is called displacement.
Answer:
Explanation:
Initially no of atoms of A = N₀(A)
Initially no of atoms of B = N₀(B)
5 X N₀(A) = N₀(B)
N = N₀ 
N is no of atoms after time t , λ is decay constant and t is time .
For A
N(A) = N(A)₀ 
For B
N(B) = N(B)₀ 
N(A) = N(B) , for t = 2 h
N(A)₀ = N(B)₀
N(A)₀ = 5 x N₀(A)
= 5
= 5 
half life = .693 / λ
For A
.77 = .693 / λ₁
λ₁ = .9 h⁻¹
= 5
Putting t = 2 h , λ₁ = .9 h⁻¹
= 5 
= 30.25
2 x λ₂ = 3.41
λ₂ = 1.7047
Half life of B = .693 / 1.7047
= .4065 hours .
= .41 hours .
Answer:
6, 3, 2, 5, 4, 1
Explanation:
Let's describe them from smallest to largest. In fact the size order is not exact as there are exceptions.
An asteroid is a rocky body which lies in the asteroid belt between Mars and Jupiter. They are typically quite small object. The largest asteroid Ceres has been reclassified as a dwarf planet.
A moon is typically a rocky body which is in orbit around a planet. Some moons such as our Moon are quite large and are typically bigger than asteroid. Some moons can actually be smaller than some asteroids.
A planet is a nearly spherical body which is in orbit around the Sun. Planets are larger than moons.
A star is what planets orbit around. It is the source of light and heat. Our Sun is a star which is many times bigger than all of the planets.
A solar system is a star and all of its planets, asteroids, comets and other bodies. It is significantly bigger than a star.
A galaxy, such as our Milky Way Galaxy, is a collection of solar systems orbiting around a central core. Most galaxies have a supermassive black hole at their centres.
Galaxies also form clusters which are large scale structures.
The universe is everything. It contains billions of galaxies.
Answer:
we have τ = I * α as the rotational equation of motion
and we also have τ = F * r
so the torque τ = 5* 0.16 Nm = 0.8 Nm
from your plot of θ vs T^2 , calculate the slope of the line
this slope will be angular acceleration α.
Then you get I = τ/α
