Answer:
Repel one another
Explanation
I am assuming you meant "two north poles will do this" Or something similar.
because you can't isolate poles, so a magnet wouldn't be just north
ANYWAYS i say repel because like terms repel, opposites attract.
Answer:
Radiation
Explanation:
There are three types of transfer of thermal energy:
- Conduction: conduction occurs when two objects/two substances are in contact with each other, and the warmer object transfers heat to the colder object through the collisions of the particles of the two objects. In this case, therefore, there is transfer of matter, so this is not the correct choice
- Convection: convection occurs in fluids. When a fluid is heated, the part of the fluid closer to the heat source gets warmer, becomes less dense and rises, replacing the colder part of fluid that sinks. Then, this part is heated, and the cycle goes on. In this type of heat transfer, there is transfer of matter, so this is not the correct choice.
- Radiation: radiation occurs when thermal energy is transferred through electromagnetic radiation. Since electromagnetic waves carry energy but not matter, in this type of heat transfer there is no overall transfer of matter. So, this is the correct answer.
We have that the best estimate for the mass of a typical lineman on a high school football team is
![100,000 g=100kg](https://tex.z-dn.net/?f=100%2C000%20g%3D100kg)
From the options
1. 100,000 g
2. 100,000 kg
3. 100,000 mg
Generally
A Typical lineman cannot be as small as
![100000mg=0.1kg=100g](https://tex.z-dn.net/?f=100000mg%3D0.1kg%3D100g)
A Typical linesman cannot be as massive as
as that is unrealistic
With the Average Mass of A Typical linesman can be
![100,000 g=100kg](https://tex.z-dn.net/?f=100%2C000%20g%3D100kg)
In conclusion
The best estimate for the mass of a typical lineman on a high school football team is
![100,000 g=100kg](https://tex.z-dn.net/?f=100%2C000%20g%3D100kg)

The question involves the knowledge of kinematics and dynamics. The answers are;
a) Time taken to stop the car = 10 s
b) The operation that slows the car is Friction
c) The size of the force = 1200 N
<h3>
What is Deceleration ?</h3>
Deceleration is the opposite of acceleration. When an object is going to rest, it will be decelerating and the final velocity will be equal to zero.
Given that the driver of a car moving at 15 m/s along a straight level road applies the brakes. The car decelerates at a steady rate of 3/2 m/s²
a) How long does the car take to stop can be found by using the formula
v = u - at
Where
Substitute all the parameters into the formula
0 = 15 - 1.5t
1.5t = 15
t = 15/1.5
t = 10 s
b) The description of the operation that slows the car down after the brake pedal is pressed is simply friction.
c) If the mass of the car is 800. The size of the force slowing the car down will be F = ma
F = 800 × 1.5
F = 1200 N
Therefore, the time taken to stop the car is 10 s and the force slowing the car down is 1200 N

Global warming is the unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. ... Temperatures are certain to go up further. Despite ups and downs from year to year, global average surface temperature is rising.
