It would be 12W because: 6v is half of 12v so half of 24w would be 12w
Answer: V = 504m/a
F = 4N
Explanation: please find the attached file for the solution
Answer:
Electron
Explanation:
In the picture, the letter A is pointing to an electron.
<h2>Thus the force of friction is 235 N</h2>
Explanation:
When the bear was at the height of 14 m . Its potential energy = m g h
here m is the mass of bear , g is acceleration due to gravity and h is the height .
Thus P.E = 27 x 10 x 14 = 3780 J
The K.E of the bear just before hitting =
m v²
=
x 27 x ( 6.1 )² = 490 J
The force of friction f = P.E - K.E = 3290 J
Because the work done = Force x Distance
Thus frictional force =
= 235 N
