Answer: Oil )Explanation:
Here Oil is the most viscous liquid.
The liquid with the most intermolecular force is high viscous. viscosity is how smoothly a liquid flows and how hardly the liquid flows it is highly viscous.
Answer:
4m/s approx
Explanation:
Step one
Given data
m1=71kg
m2=65kg
v1=3.4m/s
v2=??
We are required to find the Velocity of the second person
By applying the conservation of momentum principles
P=mv
m1v1=m2v2
Substitute
71*3.4=61*v2
241.4=61v2
Divide both sides by 61
v2=3.95m/s
v2=4m/s approx
Answer:
Either B or D. The answer itself is 2.
Explanation:
The equation for the kinetic energy would be 1/2*mv^2.
When m is doubled, we can plug in 1 and 2 to compare our answers.
Plugging in 1 for mass would give us the answer 1/2*v^2.
Plugging in 2 for mass would give us v^2. This means that the velocity was multiplied by 2, meaning that the answer is it is multiplied by 2.
I am not sure which answer is correct since there seems to be two answer choices with 2 in it, but the answer is either B or D (I will call it ABCD because I do not want to cause confusion by saying 2 multiple times).
