Answer:


Explanation:
(a)
- mass of baby,

- mass of father,

- distance between father and baby,

<u>Now, the gravitational force on baby due to father:</u>



(b)
- distance between baby and Jupiter,

- We have mass of Jupiter,

<u>Now, the gravitational force on baby due to planet Jupiter:</u>



We find that the gravitational force due to Jupiter is considerably greater than the force due to mass of father.
Answer:
Isaac Newton came up with the 3 Laws of Motion
In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. ... In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels.
Answer:
Explanation:
To solve this problem we have to take into account that the energy consumed per second is the power. Hence, by multipling the power and the time spent to arrive to the lab we obtain the total energy consumed.
But first we have to calculate the time

Now we use E=W*t for both times

A. Hence, by running the energy consumed is lower.
B.
E1=1008000J
E2=1392000J
C. Because the more intense exercise is made in a lower time in comparison with the less intense exercise, and higher the time, more energy is consumed.
The answer should be C.
Ratio it has two radioactive isotopes is compared by overtime.
Hope it helped you.
