What are two ways that convention currents in the ocean distribute the suns energy ?

1 answer:

8 0

The ocean distributes heat and soluble nutrients from the sun's energy to around the world. This is from the constant cyclical motion of the water (that's also found in air and other substances). As warm water rises, cold water takes its place so it can be heated. The process repeats.

What is the force of gravity on a dog in a space suit that's running around on the moon? The dog's body has a mass of 20 kilogra

gulaghasi [49]

Answer:

32.4 N

Explanation:

The force of gravity acting on the dog is equal to its weight on the Moon, which is given by

$W=mg$

where:

m is the mass of the dog

g is the acceleration of gravity on the moon

In this problem, we have:

m = 20 kg

g = 1.62 m/s^2 (acceleration due to gravity on the moon)

Substituting numbers into the equation, we find

$W=(20 kg)(1.62 m/s^2)=32.4 N$

A wind is blowing a small ice fishing shed along the ice to the east with a 800N force. The shed weighs 2,200N. What would the l

Answer:

0.36

Explanation:

The maximum force of friction exerted by the surface is given by:

$F_f = \mu N$ (1)

where

$\mu$ is the coefficient of friction

N is the normal reaction

The shed's weight is 2200 N. Since there is no motion along the vertical direction, the normal reaction is equal and opposite to the weight, so

N = 2200 N

The horizontal force that is pushing the shed is

F = 800 N

In order for it to keep moving, the force of friction (which acts horizontally in the opposite direction) must be not greater than this value. So the maximum force of friction must be

$F_f = 800 N$

And substituting the values into eq.(1), we can find the maximum value of the coefficient of friction:

$\mu = \frac{F_f}{N}=\frac{800}{2200}=0.36$

Which of these statements best proves that electromagnetic forces are weaker than strong nuclear forces? Neutrons do not repel o

musickatia [10]

Answer: <span>Protons do not move out of the nucleus of atoms although they repel each other.

Reasoning:

Remember that protons are particles with positive charge and they held together in the nucleus of the atom which is a tiny tiny region. As you know, like charges repel each other, which means that the protons exert a repulsion force.

That repulsion force tends to destabilize the atom. The only reason why the atom does not explode is because there is a there exists a force of attraction that exceeds the repulsion of the like charged protons. That is the strong nuclear force. Therefore, the strong nuclear forces are stronger than the electromagnetic force that tends to get the protons apart.
