The mass on the spring is bouncing.
We would call it a wave-like motion, except that it all stays in the same place. But, just like a wave, moving from the highest position to the lowest position
is one-half of a full wiggle.
(The other half consists of moving from the lowest position back up to the
highest position, where it started from.
So, half of the wave-like motion takes 0.6 seconds.
A full cycle of the wave motion ... the actual period of the bounce,
is double that much time . . .
1.2 seconds.
F = GMm/r^2
So F is proportional to 1/r^2
F2 = 2700 x ( 1 / 3^2 ) = 300N
Answer:
0 is your answereeeeerrrrr
Answer and Explanation:
TRANSPORTATION OF HEAT THROUGH CONVECTION :
- The best example of heat transfer from convection process is fan when there is too hot and we switch on the fan then the air which are produced by fan cools the room this process of removing heat is called connective heat transfer.
- When milk is too hot and we want to drink it then we blow air across milk so that milk will become cool this is also a convection process.
TRANSPORTATION OF HEAT THROUGH RADIATION :
- The best example of heat transfer from radiation from radiation process is Sun from sun we got heat in form of radiation
- When we go on the roof in night in winter days it is so cooled this is also due to radiation process.
Answer:
W = 68 J
Explanation:
On a force vs displacement chart, work is the area under the curve.
The area under the curve can be divided into a rectangle and a triangle
W = Fd = (2 N)(12 - 0 m) + ½(13 - 2 N)(12 - 4 m) = 68 N•m = J
