The ratio of T1 : T2 is 1.6
<h3>
What is Simple Harmonic Motion ?</h3>
SHM is the periodic motion of a particle along a line such that the acceleration of the body is directed toward a fixed point and proportional to its displacement.
Given that a pendulum of length 130.0 cm has a period of oscillation, T₁.
Then, The period T₁ = 2
T₁ = 2 x 3.142 
T₁ = 6.284 x 0.36
T₁ = 2.266
But if T = 0
then, m
/r = mg
the m will cancel out
Then v = 
where r = 50/100 = 0.5m
Substitute into the formula
v = 
v = 2.24 m/s
Also, given that the bob is pulled and released to move in a horizontal circle of radius 50.0 cm and the period of rotation is T2,
w = 2f
w = 2/T
but v = wr
w = v/r
Therefore,
v/r = 2/T
Substitute all the parameters into the formula
2.24/0.5 = (2 x 3.1423) /T
T = 6.284/4.472
T = 1.405 = 
The ratio T₁: T2 will be 2.266/1.405
The ratio is 1.6

Explanation:
Let i, j and k represents east, north and upward direction respectively.
Velocity due north, 
Velocity of the crosswind, 
Velocity of downdraft, 
(downward direction)
(a) Let v is the position vector that represents the velocity of the plane relative to the ground. It is given by :
(b) The speed of the plane relative to the ground can be calculated as :
v = 66 m/s
Hence, this is the required solution.
Answer:
there are two main type of root systems.
From the outside is it’s shell, and on the inside is the nucleus (on the middle) which is made or protons (positive charge) and neutrons (neutral charge which is negate and positive) and Lastly there are electrons (negative charge) that orbit the nucleus like planets orbiting the Sun. The shell gets made as the electrons orbit the nucleus.
How do atoms differ from eachother?- their atoms might have different elections, neutrons, and/ or protons inside of it. Plus the location of the elections might be different too.
