Answer:
(a) 
(b) 
Explanation:
It is given that,
Force acting on the particle, F = 12 N
Displacement of the particle, 
Magnitude of displacement, 
(a) If the change in the kinetic energy of the particle is +30 J. The work done by the particle is given by :
is the angle between force and the displacement
According to work energy theorem, the charge in kinetic energy of the particle is equal to the work done.
So,
(b) If the change in the kinetic energy of the particle is (-30) J. The work done by the particle is given by :
Hence, this is the required solution.
Answer:
P = 3800 W
Explanation:
Power is equal to energy divide by time P = E/t
plug in 4560000 J for energy
convert 20 minutes to seconds
20 * 60 = 1200 seconds
plug in 1200 seconds for time
P = 4560000/1200
P = 3800 W

Explanation:
Just took the test haha
You can drink it nothing will happen you caN BOIL ME SOME EGGS IF YOU WANT TOO
I believe it’s the mass of the box but I don’t no if I’m right
Hope this helped
