Answer: Microwaves.
Explanation: First, we have a trivial answer, and that is the visible light, which is responsible to let the information on the tv to be seen by the user.
Now, TV technology was possible thanks to the microwaves, that are used because these can carry more energy than other types, and these microwaves needed a special technology because they couldn't be handled by the current technology at the time.
You can't.
Work = (force) x (distance) .
You can squeeze distance out of the speed, but there's no way to determine the FORCE being used.
If there's no friction and the car is traveling in a straight line, then NO force is needed to keep it going. It just keeps going. (Newton's 1st law of motion.)
Answer:150Nm
Explanation:
Force=50.0N distance=3.00m
Work=force x distance
Work=50 x 3
Work=150Nm
Answer:Thermal energy is a measure of a substance 's specific heat
Explanation:
<h3>✨ <u>ASSERTION</u> :-</h3>
- Two bodies of masses M and m (M>m) are allowed to fall from the same height . If the air resistance for each be the same then both the bodies will reach the earth simultaneously .
<h3>✨ <u>REA</u><u>SON</u> :-</h3>
- For same air resistance, acceleration of both the bodies will be same .
[A] If both assertion and reason are true and reason is the correct explanation of assertion .
[B] If both assertion and reason are true but reason is not the correct explanation of assertion .
[C] If assertion is true but reason is false
[D] If both assertion and reason are false
✍️ The force acting on the body of mass M are [its weight] ‘<u>Mg</u>’
- Mg are acting vertically downwards
- And air resistance F acting vertically upward .
Hence,
⚡ Now, M > m therefore, the body with larger mass will have greater acceleration and it will reach the ground first .
