Answer:
45000 Kg.m/s
Explanation:
change in momentum = m( v¹-vi)
=3000(25-10)
= 45000
Answer:
Explanation:
A ) weight of air + weight of tank = 013.5 + 3.2
= 16.7 kg
volume of air
= 3.2 / 1.225 = 2.61 m³
= volume of water displaced = 2.61 m³
weight of water displaced = 2.61 x 1025
= 2675.25 kg
buoyant force = 2675.25 kg
buoyant force = weight of displaced sea water
= volume of displaced sea water x density
= 15.7 x 10⁻³ x 1025
= 16.0925 kg
net force = buoyant force - weight
= 2675.25 - 16.7
= 2658.55 kg
B ) net force will be in downward direction as weight is higher .
C ) weight of tank + weight of water in it
= 13.5 + 15.7 x 10⁻³ x 1025
= 13.5 + 16.0925
= 29.5925 kg
buoyant force = 16.0925 kg
net force = 29.5925 - 16.0925
= 13.5 kg
D ) net force down wards
To solve this problem it will be necessary to apply the interference principle. Under this principle interference is understood as a phenomenon in which two or more waves overlap to form a resulting wave of greater, lesser or equal amplitude. In this case, if both are at the same point, the result of the total displacement will be the sum of the individual displacements, therefore
Therefore the resulting displacement above equilibrium is 140cm
I think it would be a theory because it's a experiment that can be repeated and get the same or similar results
