What is the weight of a 45 kg box? N

Answers

Answer 1
Answer:

45 kg * 9.8 m/s^2 = 441 N.
Answer 2
Answer:

Answer:

The force of a mass's weight is defined as its mass * acceleration due to gravity.

On Earth, g is about 9.8 m/s^2. This will be the acceleration due to gravity.

Then, 45 kg * 9.8 m/s^2 = 441 N.

What force stops a car from sinking into the road surface?

Answers

Answer:

Explanation:

There are so many factors which works to stop a car from sinking into road surface. One is reaction force other factors are density of material from which the car is made of, mass and shape of car.but the most important force is the reaction force. According to the Newton's 3rd law of motion:- every force have equal force acting in opposite direction.
I believe it's technically referred to as the Normal force.
However I like to think of it as the reaction force, as it is the force that is a result of obeying Newton's 3rd law ("For every action, there is an equal and opposite reaction"). The upward force from the ground is the reaction to the downward force of gravity.

A wet towel is hanging on a clothesline in the sun. What process does the towel dry by?

Answers

by convection radiation...the heat from the sun travels to the towel through air molecules(radiation),the heat is then transfer in the towel through water molecules(convection)..thereby gradually drying up the water molecules in the towel
The towel dries by the process of evaporation. The sun heats up the water and changes it to water vapour.

The breeze during a sunny day at the beach is usually a result of _________________________________________.                                                                          A) the water heating faster than the landB) planes flying overheat with large banners
C) the land heating faster than the water
D) boats passing the shore too closely

Answers

C, Land heats and cools faster than water! 
The answer is (C) The land heating faster than water.

Land always heats and cools down faster than sea. During daytime, land heats faster. During night, land cools down faster than water.
