1.)the microwaves are absorbed by the water molecules in the cocoa. this causes the water molecules to vibrate very fast.
2.)this fast vibration causes the molecules to heat themselves up by means of bumping into each other (friction).

- A ball is dropped from a height = H
- The total distance covered in last second of its motion is equal to the distance covered in first 3 second .

- The height of the journey .

We have know that,

Where,
- u = initial velocity = 0m/s
[Note :- Here, acceleration is ‛acceleration due to gravity’ .]
=> S = 1/2 × 10 × (3)^2
=> S = 5 × 9
=> S = <u>4</u><u>5</u><u>m</u> -----(1)
✒ If the ball takes ‛n’ second to fall the ground, then distance covered in nth second is,

=> Sn = 0 + 10/2 (2 × n - 1)
=> Sn = 5 (2n - 1)
=> Sn = 10n - 5 -----(2)
Therefore,
=> 10n = 45 + 5
=> n = 50/10
=> n = <u>5</u>
Now put the value of ‛n = 5’ in equation(2), we get
=> Sn = 10 × 5 - 5
=> Sn = 50 - 5
=> <u>Sn</u><u> </u><u>=</u><u> </u><u>4</u><u>5</u><u>m</u>
The height of the journey is “ <u>4</u><u>5</u><u>m</u> ” .
Pretty sure it is A:Light wave
As they say nothing is faster than the speed of light.
Answer: Contact the National Aeronautics and Space Association
Explanation:
The National Aeronautics and Space Association is an independent organization in US which aims to enable a safe, secure, efficient space journey and launch of new satellites, spacecraft beyond the earth's orbit. It can give better information for the space travel already conducted by the astronauts. Thus will help in writing the report as it is the best place to find the information.
