Answer:
energy from excess mass
Explanation:
The correct answer for the given question out of the given options is the option " energy from excess mass ".
This happens due to the fact that some of the matter is converted into the energy during the fusion of atoms.
The relation that can be stated is E = mc²
where,
E is the energy
c is the speed of the light
m is the mass of the matter
7264 Joule
Use the formula K=0.5*mass*velocity^2
Answer:
The bird appears farther
Explanation:
This is because as the light from the bird travels into the water which has a higher refractive index than air, light rays from the kingfisher bird bend towards the normal at the water surface and thus enter the eye of the scuba diver. Now, if we project the light rays from the eyes of the scuba diver into the air, we see that they appear to come from a point farther than that of the actual kingfisher bird perched on the branch.
<u>So, the bird appears to the diver to be farther from the surface than the actual bird</u>
Answer: 3rd option
Explanation: Since it has less mass and same force as other object it will have higher acceleration
Answer:
4) Driving in a straight line at 60 miles per hour
Explanation:
1) Driving 60 miles per hour around a curve
2) Going from 0 to 60 miles per hour in 10 seconds
3) Slamming on the brakes to come to a stop at a stop sign
4) Driving in a straight line at 60 miles per hour
1) The speed is constant here, but in circular motion you have an acceleration that is v^2/r, where v is the speed and r the radius
2) You are accelerating from 0 to 60
3) You are desaccelerating
4) constant speed , no acceleration
