Answer:
Newton's third law of motion states that every action has an equal and opposite reaction. This indicates that forces always act in pairs. Reaction forces are equal and opposite, but they are not balanced forces because they act on different objects so they don't cancel each other out.
<h3>
Answer:</h3>
80 kgm/s
<h3>
Explanation:</h3>
<u>We are given;</u>
- Mass of the Canoe is 32 kg
- Speed of the Canoe is 2.5 m/s
We are required to calculate the momentum of the Canoe?
- We need to know that momentum is the product of mass of an object and its speed.
Momentum = Mass × speed
Therefore;
Momentum = 32 kg × 2.5 m/s
= 80 Kgm/s
Thus, the momentum of the Canoe is 80 kgm/s.
Answer: touch the pan to the burner
Explanation:
There are three modes of heat transfer:
conduction, convection and radiation.
For conduction, the heat transfers from a hot object to a cold object when the two are in contact.
For convection there is bulk motion of fluid occurs which transfers the heat.
For heat transfer by radiation, medium is not required.
Thus, to demonstrate conduction between pan and burner, the pan must touch the burner.
These days, scientists all over the world use a standard system of measurements. It's the SI or metric system.
What about scientists in the United States, Liberia, and Burma ?
These three countries are the only ones in the world that haven't
adopted the metric system. What do THEY do ?
Easy. When scientists in those countries are off work, they use the
inches, yards, feet, quarts, miles and gallons that everybody around
them is using. But when they go to work, they use the same metric
system that everyone else in the world is using.
Answer:
Yes it is balanced
Explanation:
Because 10-10= a net force of 0N
Its equal (balanced)
