you push a friend sitting on a swing. she has a mass of 50kg and accelerates at a rate of 4 m/s2. find the force you exerted
Hoochie [10]
Mass of the friend sitting on the swing = 50 kg
Rate of acceleration = 4 m/s^2
The above information's are already given in the question. We need to utilize these information's in such a manner that the answer to the question can be determined easily.
We already know that
Force = Mass * acceleration.
This formula has to be used to find the force exerted.
Then
Force exerted = Mass of the friend * Acceleration
                       = (50 * 4) kg m/s^2
                       = 200 Newton
So the force exerted by me is 200 Newton. I hope the explanation and the procedure is clear to you and you are satisfied with it.

Which of the following reactions is the least energetic? Question 18 options: ATP + H2O → ADP + Pi ATP + H2O → AMP + PPi AMP + H
Mama L [17]

Answer:

The correct answer is AMP+H2O→ Adenosine + pi

Explanation:

The above reaction is least energetic because there is no phosphoanhydride bond present with adenosine mono phosphate.Phospho anhydride bond is an energy rich bond.

As a result hydrolysis of AMP generates very little amount of energy in comparison to the hydrolysis of ATP and ADP.

You are experimenting on the effect of temperature on the rate of reaction between hydrochloric acid (HCl) and potassium iodide
erica [24]

Answer is "B - 700,000".<span>

<span>Kinetic energy of a single particle (atom or molecule)<span> is directly proportional to its temperature according to the following equation.</span></span>
           KE = (3kT)/2

<span>Where </span>KE<span> is the kinetic energy of a single atom/molecule (</span>J<span>), </span>k<span> is the Boltzmann constant (</span>1.381 × 10</span>⁻²³ J/K<span>) and </span>T<span> is the temperature (</span>K<span>) </span><span>

When temperature increases, then the kinetic energy increases.

<span>If kinetic energy of atoms increases, then there will be more motions which create many collisions.</span></span>

In the reaction MgCl2 + 2KOH Mg(OH)2 + 2KCl, if 3 moles MgCl2 are added to 4 moles KOH, what determines how much Mg(OH)2 is made
LenKa [72]
The correct option is C. The amount of MgCl2. we know this because <span>no matter how much you increase KOH, if you dont increase Mgcl2, the amount of Mg(OH)2 remains the same. Hope this works for you</span>
