Answer:
A)Object 1 has the greater magnitude of its momentum.
B)The objects 2 have the greater kinetic energy.
Explanation:
For object 1 :
v₁ = v ,m₁ = 2 m
For object 2 :
,m₂=m
We know that linear momentum given as
P = M V
M=Mass , V=Velocity
For object 1 :
P₁ =m₁ v₁
P₁ =2 m v
For object 2
We can say that object 1 have more momentum.
The kinetic energy
Therefore both the object 2 have higher kinetic energy.
Answer:
Surface tension is the tendency of liquid surfaces to shrink into the minimum surface area possible.
Surface tension is caused by effects of intermolecular forces at liquid interface.
Surface tension increases as intermolecular forces increases.
Explanation:
- Surface tension is the tendency of liquid surfaces to shrink into the minimum surface area possible. It can also be seen as the energy required to increase the surface of a liquid by a unit amount.
- Surface tension is caused by the mediating effects of intermolecular forces at the liquid interfaces. Example in water, surface tension is caused by the mediating effect of the force between hydrogen and oxygen molecules. Liquids tends to reduce their surface area because of inward attarction of the liquid molecules.
- Surface tension increases as intermolecular forces increases. Also, surface tension decreases as intermolecular forces decreases.
Answer:
350N
Explanation:
According to Newton's 3rd law of motion, 2 objects that interact experience an equal and opposite force on each other. So if the bat exerts 350N of force on the baseball, the baseball must exert 350N on the bat.
This, in case you were interested, is what causes the recoil of the bat.
Answer:
3 meters per second
Explanation:
72 divided by 3= 24 meters in 8 seconds
24/8= 3, so 3 meters per second
