Answer:
move downward
Explanation:
The complete statement of the question is
We fully submerge an irregular 3 kg lump of material in a certain fluid. The fluid that would have been in the space now occupied by the lump has a mass of 2 kg. (a) When we release the lump, does it move upward, move downward, or remain in place
(a)
= Force of buoyancy acting on the irregular lump in upward direction
= mass of irregular lump of material = 3 kg
= mass of fluid displaced = 2 kg
Force of buoyancy on the irregular lump in upward direction is given as the weight of fluid displaced. hence
weight of the irregular lump of material is given as
Since the weight of lump in down direction is greater than the force of buoyancy in upward direction. hence the lump of material moves in down direction
Answer:
7.55 g
Explanation:
Given that:
Heat of fusion = 333kj/kg
Heat capacity, c = 4190 j/kg /k
The Number of grams of ice that will melt can be represented as y:
Number of grams of ice that will melt * heat of fusion = specific heat capacity * temperature change
y * 333 * 10^3 J = (4190) * (6 - 0)
333000y = 25140
y = 25140 / 333000
y = 0.0754954 kg
y = 0.0754954 * 100
y = 7.549 g
Hence, Number of grams of ice that will melt = 7.55 g
Answer:
There is less gravitational force in space.
Explanation:
Gravity doesn't exist as it does on Earth. Earth's gravity is as 6 times stronger as it is on the moon.
35m/s is meters per second.
35x35=1225
it will have gone a total of 1225 meters on thirty five seconds
