Answer:
e) None of these is true
Explanation:
Given that
Temperature = 0 K
We know that relationship between kelvin and Farenheit scale
Now by putting the values
So F= - 459.67°F
So we can say that 0 K is equal to - 459.67°F.
So the our option e is correct.
Answer: B. A gravitational field
Explanation:
Surrounding earth is gravitational field. Gravitational field is a region of space were gravitational force can be felt and gravitational force is the gravitational pull on the surface of the earth. The presence of this gravity is what allow us to be able to walk freely without falling. It also make us jump up and be able to land back on the ground. Assuming there are no force of gravity in the surface of the earth, there won't be any possibility of landing back on the ground after jumping.
- Pressure = 5000 Pa
- Contact Area = 0.04 m^2
- Acceleration due to gravity = 9.8 m/s^2
- Let the force be F.
- We know, Force = Pressure × Contact Area
- Therefore, Force = 5000 Pa × 0.04 m/s^2
- or, Force = 200 N
- We know, force = mass × acceleration
- Therefore, mass = force ÷ acceleration
- or, mass = 200 N ÷ 9.8 m/s^2 = 20.4 Kg

Hope you could understand.
If you have any query, feel free to ask.
If John goes running around his neighborhood everyday after work, the health-related factors that he will be improving through this type of training is any factors that involve the improvement of cardiorespiratory systems. This would improve a lot such as his circulation, endurance, stamina, and etc. Hope this helps.
