Answer:

Gravity

Explanation:

Answer:

Time, t = 0.015 seconds.

Explanation:

Given the following data;

Mass, m = 0.2kg

Force, F = 200N

Initial velocity, u = 40m/s

Final velocity, v = 25m/s

To find the time;

Ft = m(v - u)

Time, t = m(v - u)/f

Substituting into the equation, we have;

Time, t = 0.2(25 - 40)/200

Time, t = 0.2(-15)/200

Time, t = 3/200

Time, t = 0.015 seconds.

Note: We ignored the negative sign because time can't be negative.

Answer:

B(Ambassador)

Explanation:

The president appoints ambassadors to foreign countries to represent the United States.

Explanation:

Given

Mass(M) = 80,000 kg

Acceleration (a) = 35 m/s²

Force (F) = ?

We know we have the formula

F = m * a

= 80000 * 35

= 2800000

= 2.8 * 10 ^ 6 N

The force is 2.8 * 10 ^ 6 N.

Hope it will help :)❤

If a rocket has a mass of 80,000 kg and accelerates at a rate of 35 m/s2.  then the force that provides this acceleration would be 2800000 Newtons.

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

The mathematical expression for Newton's second law is as follows,

F = m*a

As given in the problem we have to find the force that provides the acceleration of 35 meters / second², if the  rocket has a mass of 80,000 kg,

The force acting on the rocket =  80,000 × 35

                                                   = 2800000 Newtons

Thus, the force acting on the rocket would be 2800000 Newtons.

Answer: Will not accelerate.

Explanation: When all the forces acting upon an object balance each other, the object will be at equilibrium; it will not accelerate.

Answer:

1. the rocks at the bottom of the aquarium

2.the fish and maybe the plants (if you use live plants)

3. fish interact with there no living things like how one would hide in the grass or something like that.

4. decorations (like a cave or fake house, tho the aquarium its self is a home)

5.they would die, and rot.

Explanation:

rocks are nonliving

fish are living things and so are plants

fish can hide in the plants

the fish can "live" in the decorations, but the aquarium itself is its home.

if something reaches the end of its life span it dies.

Explanation:

Remember Newton's Second Law.

If the force acting on both bikers is the same, we can look at the relationship between acceleration and mass.

If Biker 1 has a mass of 10kg and Biker 2 has a mass of 20kg, and both are being acted upon by a force of 100 N, let's see what that looks like. [tex]100 = 10*a_1 \rightarrow a_1 = 100/10 = 10[/tex]

[tex]100 = 20 *a_2 \rightarrow a_2 = 100/20 = 5[/tex]

So, given the same force, an object with GREATER mass will have less acceleration.

Answer:

0.05m

Explanation:

Given parameters:

Force constant of the spring  = 40000N/m

Potential energy  = 42J

Unknown:

Extension  = ?

Solution:

To solve this problem, use the expression below:

           E.PE  = [tex]\frac{1}{2}[/tex] k e²  

k is spring constant

e is the extension

              42  =  [tex]\frac{1}{2}[/tex]  x 40000 x e²  

               e  = 0.05m

Rutherford's model of atoms describes the atom as a tiny, dense particle which contains a positively charged nucleus with electrons which are negative charged moving in orbitals.

Rutherford's model of atoms described the atom as a tiny, dense, positively charged core particle which is called a nucleus, in which nearly all the mass of the atom is concentrated, around within the nucleus which the light, negative constituents, called electrons, circulate at some specific distance, much like the planets which are revolving around the Sun.

During the Rutherford's experiment, the alpha particles are bombarded on the thin piece of gold foil. The alpha particles were expected to pass easily through this gold foil. The discovery of the nucleus of atom was a result of the Rutherford's observation in which a small percentage of the positively charged particles that is protons bombarding on the metal's surface.

Answer:

C. Kinetic energy changed to potential energy.

Explanation:

The kinetic energy is converted to potential energy when he reaches the top of the hill.

As with every system, energy is neither created nor destroyed but transformed from one form to another.

This is from the law of conservation of energy.

Kinetic energy is produced when Harry moves the up the hill. As he reaches the top of the hill and comes to rest, potential energy is formed.

Potential energy is the energy due to the position of a body.
