Answer:
At the center of the earth if the ball is dropped in the hole then it's mass will be the same but the weight of the ball will be zero. As the gravity at the center of earth will be zero. As,
W = mg
However at the surface of earth the ball will have the maximum weight.
Explanation:
Answer:
all of the particles are at rest (v = 0)
Explanation:
Therefore, since nothing is moving, the total momentum of the system must also be zero.
- Mass of the truck (m) = 30000 Kg
- Velocity (v) = 25 m/s
- Let the momentum be p.
- We know, momentum = mass × velocity
- Therefore, the momentum of the truck (p)
- = mv
- = (30000 × 25) Kg m/s
- = 750000 Kg m/s

The concentration of a solution is a measure of the amount of solute that has been dissolved in a given amount of solvent or solution. A concentrated solution is one that has a relatively large amount of dissolved solute. A dilute solution is one that has a relatively small amount of dissolved solute.
The glucose molecules in the intestine might be in a higher concentration than in the intestinal cells and blood – for instance, after a sugary meal. At this point it will diffuse from high concentration in the intestine to a lower concentration in the blood. This doesn't require energy.
