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.
Answer:
- You may normally expect a <em>slow</em> reaction if a <em>high</em> activation energy is required.
- Or, You may normally expect a <em>fast</em> reaction if a <em>low</em> activation energy is required.
Explanation:
- To answer this question, we should define firstly the term of activation energy.
- The activation energy is the minimum energy must the reacting molecules have to initiate the chemical reaction.
- Also, we can define it as The energy barrier that the molecules must posses an amount of energy equal or more than the value of this barrier.
- So, as the activation energy be of low value, the possibility that the reacting molecules can have this amount of energy to initiate and proceed the reaction increases and the reaction rate also increases.
- Additionally, as the activation energy be of high value, the possibility that the reacting molecules can have this amount of energy to initiate and proceed the reaction decreases and the reaction rate also decreases.
Thus, we can answer this question as:
- You may normally expect a <em>slow</em> reaction if a <em>high</em> activation energy is required.
- You may normally expect a <em>fast</em> reaction if a <em>low</em> activation energy is required.

Answer:
A source of electricity, a wire coil, and an iron core
Explanation:
An electromagnet has three critical components:
1. A source of electricity
This is often a battery.
It generates the electric current that produces the magnetic field.
2. A wire coil
The wire carries the electric current.
Stacking the wire into loops makes a stronger magnetic field.
The more loops in the coil, the stronger the field.
3. An iron core
An iron core greatly increases the strength of the magnetic field within it and at its ends.
Answer:
Strong acids and bases both denature proteins by severing disulphide bonds and at higher temperatures, can break proteins into peptides, or even individual amino acids.
