While falling, both the sheet of paper and the paper ball experience air resistance. But the surface area of the sheet is much more than that of the spherical ball. And air resistance varies directly with surface area. Hence the sheet experiences more air resistance than the ball and it falls more slowly than the paper ball.
Hope that helps!
Answer:
to the left the first answer can be "Consumer" and under it can go "plant"
to the right the first answer on the top can be "Carnivore" under it can go "Herbivore" and under it can go "Producer"
I just had this question and its right
F=ma
F= 4x1.2
F= 4.8 N
F= 4gsin30 - Friction
Friction= 19.6 - 4.8 N
Friction= 14.8 N
Friction= u x 4gcos30
14.8 / 4gcos30 = u
u= 0.43596...
u= 0.44
coefficient is 0.44
Answer:
d) kinetic energy transformed to mechanical energy
Explanation:
Wind energy comes from its movement, so kinetic energy
Em = K = ½ m v²2
This energy spins the mill aspadle that this movement of the rotor within a magnetic field creates electricity in accordance with Faraday's law.
Consequently, from the above we should make a graph of the wind speed (kinetic energy) according to the electricity produced
The correct answer is d
