The wieght of a sphere in air is 70g in tap water is 60g in strong salt solution is 55g. Find the volume of the sphere?

Dear student,
 
Density = mass/ volume
 
w1 = 70g, w2 = 60g, w3 = 55g
 
1 = 60/volume, volume = 60units ( in tap water)
 
density of air at sea level = 1/800 th density of water, density of tap water is approximately equal to 1.
 
1/800 = 70/volume = 56000 units ( in air)
 
PLease get back to us for further clarifications.
Thankyou

A boy throws a steel ball straight up. Consider the motion of the ball only after it has left the boy's hand but before it touches the ground and assume that forces exerted by the air are negligible. For these conditions, the force(s) acting on the ball is (are): a. A downward force of gravity along with a steadily decreasing upward force b. A steadily decreasing upward force from the moment it leaves the boy's hand until it reaches its highest point on the way down there is a steadily increasing downward force of gravity as the object gets closer to the earth c. Constant downward force of gravity along with an upward force that steadily decreases until the ball reaches it highest point on the way down there is only a constant downward force of gravity d. Constant downward force of gravity only
