A rubber duck is 10 percent submerged when taking a bath on planet Earth. What percentage would it be submerged on planet Qwfasu, where the gravitational acceleration is four times stronger, namely 4g? A :5 B: 10 C :20 D :40 E :80 The elephant has a volume of 0.4 m 3 . If it is taking a bath with 69 percent of its volume under water (fresh water, density 1 g/cm 3 ), how much average pressure do its feet exert on the bottom of the pool? (in kPa) Solution A. Submerged fraction does not depend upon aacceleration due to gravity . It only depend on;- a. density of material b. density of fluid c. volume of material . so submerged percentage will remain same answer =10% .

1. A rubber duck is 10 percent submerged when taking a bath on planet Earth. What percentage
would it be submerged on planet Qwfasu, where the gravitational acceleration is four times
stronger, namely 4g?
A :5 B: 10 C :20 D :40 E :80
The elephant has a volume of 0.4 m 3
. If it is taking a bath with 69 percent of its volume under
water (fresh water, density 1 g/cm 3
), how much average pressure do its feet exert on the bottom
of the pool? (in kPa)
A : 18.2 B : 21.3 C : 25.0 D : 29.2 E : 34.2
Solution
A.
Submerged fraction does not depend upon aacceleration due to gravity . It only depend
on;-
a. density of material
b. density of fluid
c. volume of material .
so submerged percentage will remain same
answer =10%
