Answer:
u need to explain more !!
Explanation:
Answer:
F = 0.075 N
Explanation:
given,
diameter of ping pong ball = 2.55 cm
average density of the ball = 0.116 g/cm³
Force require to hold the ball completely submerged= ?
Volume of the ball


V = 8.63 cm³
density of water = 1 g/cm³
force required to keep the ball submerged is equal to


F = 7.63 x 9.8 x 10⁻³
F = 0.075 N
Force required to keep the ball inside the water is equal to 0.075 N
As the artic fox has very small ears it helps prevent the heat from his body from escaping quickly.
The bigger the ears the faster the heat escapes basically.
I think it is 18(c.m)2 but their is no unit for the length,width,height
