Answer: |F| = 1.28 x 10⁵ N
Explanation:
an impulse results in a change of momentum
FΔt = mΔv
F = m(vf - vi)/t
F = 2000(0 - 32) / 0.5
F = -128,000
|F| = 1.28 x 10⁵ N
Answer:
two separate forces
Explanation:
Electricity and magnetism are two separate forces. However, they come together in a field called electromagnetism. Both types of forces are linked; a moving magnet may push electric charges and trigger electric current. Objects which have both positive and negative charges are mutually repulsive to each other, and those with opposite charges are mutually attractive.
Answer:
a =45 m/s2
t = 2 seconds
Explanation:
Hi, to answer this question we have to apply the next formula:
v^2 = u^2 +2 a d
Where:
v = final velocity = 90 m/s
u = initial velocity = 0 m/s (shots from rest)
a = acceleration (m/s2)
d = distance = 90m
90^2 = 0^2 + 2a(90)
Solving for a:
8,100= 180 a
8,100/180 = a
a = 45 m/s^2
For time:
v = u + at
90 = 0 + 45t
90/45=t
t =2 seconds
The diagram that shows how sunlight is radiated back into the Earth’s atmosphere as heat(infrared radiation) is of the Greenhouse effect.
The greenhouse effect is a natural phenomenon that occurs on Earth and heats up our atmosphere.
The name of this effect is derived from a greenhouse, which is used to grow crops in a special environment.
A greenhouse is basically a house that is made up of glass. The glass allows heat to enter the house but it does not allow the heat to escape to the outside thus keeping the greenhouse warm.
Some gases that are responsible for this effect are known as greenhouse gases. These gases are carbon dioxide, methane, chloro- fluoro carbons, etc.
These gases trap the heat of the sun and raise the temperature of Earth thus causing global warming.
Thus, the diagram that shows how sunlight is radiated back into the Earth’s atmosphere as heat(infrared radiation) is of the Greenhouse effect.
