Answer:
- High internal validity as there is good control over all variables
- Allows for precise control over extraneous variables and IV
- Easy to replicate due to standardised procedure
you can choose one of them
hope this can help you
Their linear inertia is equivalent to their masses. Let the inertia of the first moose be m₁ and the second be m₂.
m₁u + m₂u = (m₁ + m₂) x 1/3 u
3m₁ + 3m₂ = m₁ + m₂
3 m₁/m₂ + 3 = m₁/m₂ + 1
m₁/m₂ = 2
The ratio of their inertias is 2
The answer Is B! Good luck
Answer:
B) with 9/10 submerged
Explanation:
= mass of ice cube
= density of soft drink
= Volume of soft drink displaced
ice cube floats in the soft drink when the force of buoyancy on it balances its weight. Force of buoyancy acting on the cube in upward direction is same as the weight of the soft drink displaced. hence we can write
weight of ice cube = weight of soft drink displaced


we see that the acceleration due to gravity cancel out both side and hence it does affect as astronaut is on earth on in a lunar module.
