Answer:
If you were to inject air into space what would have happen?
Explanation:
In order for air to defy gravity, it would require atmospheric pressure. But air dosen't defy gravity unless it has the support of atmospheric pressure.
I feel like it should be the same since the force is the same
<h3><u>Answer;</u></h3>
All types of
Crystals can have <em><u>all types of</u></em> bonds between their atoms.
<h3><u>Explanation</u>;</h3>
- <em><u>Crystals are solid materials which contains atoms, molecules or ions that are arranged in a complex structure forming a crystal lattice.</u></em>
- <u><em>Crystals may have all types of bonds</em></u>, these includes; <em><u>ionic bonds, formed as a result of transfer between a metallic bond and a non-metal atom, Covalent bond, formed as a result of sharing electrons between non metal atoms, hydrogen bonds, metallic bonds Van der Waals bonds, etc.</u></em>
Answer:
The time rate of change of the electric field between the plates is 
Explanation:
From the question we are told that
The radius is 
The distance of separation is 
The current is 
Generally the electric field generated is mathematically represented as
Where 
is the permitivity of free space with a value
So the time rate of change of the electric field between the plates is mathematically represented as
But 
So
substituting values
Answer:
A.) 4 revolution
B.) 0.2 revolution
C.) 4 seconds
D.) 2.75 m/s
Explanation:
Given that a merry-go-round a.k.a "the spinny thing" is rotating at 15 RPM, and has a radius of 1.75 m
Solution
1 revolution = 2πr
Where r = 1.75m
A. How many revolutions will it make in 3 minutes?
(2π × 1.75) / 3
10.9955 / 3
3.665 RPM
Number of revolution = 15 / 3.665
Number of revolution = 4 revolution
B. How many revolutions will it make in 10.0 seconds?
First convert 10 seconds to minutes
10/60 = 0.167 minute
(2π × 1.75) / 0.167
10.9955 / 0.167
65.973
Number of revolution = 15 / 65.973
Number of revolution = 0.2 revolution
C. How long does it take for a person to make 1 complete revolution?
15 = 1 / t
Make t the subject of formula
t = 1/15
t = 0.0667 minute
t = 4 seconds
D. What is the velocity in m/s of person standing on its edge?
Velocity in m/ s will be:
Velocity = (15 × 2pi × r) / 60
Velocity = 164.9334 / 60
Velocity = 2.75 m/s
