sergiy2304 [10]

Answer:

F = 7,916,955.0N

Explanation:

According to newtons second law

Force = mass * acceleration

Given

mass = 52.0kg

distance S = 22.0m

time t = 17.0 ms = 0.017s

We need to get the acceleration first using the formula;

S = ut+ 1/2at²

22 = 0 + 1/2 a(0.017²)

22 = 0.0001445a

a = 22/0.0001445

a = 152,249.13m/s²

The magnitude of the average force exerted will be;

F = ma

F = 52 * 152,249.13

F = 7,916,955.0N

A dog of mass 4 kg runs up a hill of height 8 m. How much gravitational potential energy does the dog gain?
Genrish500 [490]
A. 314 because when you use the formula for the GPE ; GPE=MGH or means mass times gravity time height (4x8x9.8) and thats equivalent to 313.6 which rounds up to 314. Hope it helps

A hydrogen atom that has lost its electron is moving east in aregion where the magnetic field is directed from south to north. I
Kitty [74]

Answer:

a. up

Explanation:

As per the rule of Fleming left hand, the three fingers should be places in a perpendicular manner i.e. mutually also.

The fore finger depicts the field direction

The middle finger depicts the velocity

And, the thumb finger depicts the force direction that experienced on that particle i.e. charged

So the electrons would be deflects to up

Hence, the correct option is a.

What is the mathematical equation for calculating the internal energy of a<br> diatomic gas? <br> -
Mariulka [41]

Answer:

U = 5/2 NkT.

Explanation:

A diatomic molecule = H₂, O₂, N₂ .....etc

A diatomic molecule has 5 degrees of freedom.

  • 3 transnational modes = x, y, z
  • 2 rotational modes = ωx , ωy

So,  the internal energy for diatomic gases is :

U = 5/2 NkT.
