A toddler rolls off of his bed and hits the floor with a thud 0.53m below. If he lands 0.2m away from the base of the bed, how long did he fall for? t = ?
dy = ?
dx = ?
ax = ?
ay = ?

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

d

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)

the answer is b, have negligible mass
