Answer:

Explanation:

The elastic potential energy stored in a sprig is given by

U = \frac{1}{2}Kx^{2}

Where, K is the spring constant and x be the displacement.

Substitute, K = 50 N/m and U = 5 J

5 = \frac{1}{2}\times 50\times x^{2}

By solving, we get

x = 0.44 m = 0.4 m0.4 m

It takes 500 W of power to move an object 96 m in 12 s. What force is being applied to the object?
agasfer [191]

Answer: 125/24 N

Explanation:

The work can be calculated with W = Fs

Where W = work

F = force

and s = displacement

Let's set up the equation:

500w = F * 96m

\frac{500}{96} = 125/24 or roughly 5.2 N of force

The Force Of Gravity Acting On A Childs Mass On Earth Is 490 newtons whats the childs mass
Flauer [41]
Force of gravity on an object is the weight of the object and is given by mass times accerelation due to gravity. The accerelation due to gravity is the accerelation of an object in free fall and is given by 9.8m/s^2. Given that the force of gravity acting on a child's mass on earth is 490 newtns, i.e. F = mg which means that 490 newtons = 9.8 times mass. Therefore, mass of the child is 490 / 9.8 = 50 kg.

Select the correct answer.

The force of a test charge would be doubled if the electric field is doubled.

Answer: Option A

<u>Explanation:</u>

Electric field is the region or range up to which a charge particle will have its influence of electric energy on another charged particles. So the experienced force by the test charge up to a certain range is defined as the electric field of that charged particle.

This means that the electric field strength is inversely proportionate to the test charge and directly proportionate to the force acting on the test charge.  As ,

               E=\frac{\text { Force }}{\text { Test charge }}

So, force will be product of electric field strength with test charge.  Thus,

              \text { Force } \propto \text { Test charge and Force } \propto \text { Electric field }

So, if there is increase in the electric field, then there will be increase in the force of the test charge. Thus, if the electric field is doubled thereby the force of a test charge will also be doubled.

Baby Sadie gets a new rubber ducky for her first birthday! She sees that it floats in the bathtub during bath time. What do you
DIA [1.3K]
The rubber ducky was able to float because it’s density was less than the water. Water has a density of 1, meaning the rubber ducky must have a density lower than 1.
