What do we know that might help here ?
-- Temperature of a gas is actually the average kinetic energy of its molecules.
-- When something moves faster, its kinetic energy increases.
Knowing just these little factoids, we realize that as a gas gets hotter, the average speed of its molecules increases.
That's exactly what Graph #1 shows.
How about the other graphs ?
-- Graph #3 says that as the temperature goes up, the molecules' speed DEcreases. That can't be right.
-- Graph #4 says that as the temperature goes up, the molecules' speed doesn't change at all. That can't be right.
-- Graph #2 says that after the gas reaches some temperature and you heat it hotter than that, the speed of the molecules starts going DOWN. That can't be right.

Answer:
longing for social inclusion.
Explanation:
Ross here is longing for social inclusion.
He decides to campaign for the his fraternity brother not by choice or will but by peer pressure and social inclusion because most of the students campaigned for Henry so he supports Henry as well. Moreover, he did not be feel left out and he did not have a clear preference as well.
Answer: Vb is the vector (-5.37m/s, 8.59 m/s), with a module 10.13m/s
then the ratio Vb/Vr = 10.13m/s/5.37m/s = 1.9
Explanation:
We can use the notation (x, y) where the river flows in the x-axis and the pier is on the y-axis.
We have Vr = (5.37m/s, 0m/s)
Now, if the boat wants to move only along the y-axis (perpendicularly to the shore).
The velocity of the boat Vb will be:
Vb = (-c*sin(32). c*cos(32))
Then we should have that:
5.37 m/s - c*sin(32) = 0
c = (5.37/sin(32))m/s = 10.13 m/s
the velocity in the y-axis is:
10.13m/s*cos(32) = 8.59 m/s
So Vb = (-5.37m/s, 8.59 m/s)
the ratio Vb/Vr = 10.13m/s/5.37m/s = 1.9 where i used Vb as the module of the boat's velocity.
Explanation:
It is given that, Onur drops a basketball from a height of 10 m on Mars, where the acceleration due to gravity has a magnitude of 3.7 m/s².
The second equation of kinematics gives the relationship between the height reached and time taken by it.
Here, the ball is droped under the action of gravity. The value of acceleration due to gravity on Mars is positive.
We want to know how many seconds the basketball is in the air before it hits the ground. So, the formula is :
t is time taken by the ball to hit the ground
is initial speed of the ball
So, the correct option is (A).
Hope it helped you.
My name is Charlie.
Today this question is about science,or chemistry.
A. Acceleration is a correct answer. Acceleration is a rate of change in velocity.
It change in velocity/change in time. Next, to slope will be indicated by the acceleration.
B Change in position is a incorrect answer.
C. Velocity is a incorrect answer. Velocity is a displacement of an object during a specific unit of time. It can used two measurements are needed to determine velocity. It displacement or by the time. Displacement it includes a direction, so the velocity will also includes a direction. It can used speed with direction. Velocity it can be average velocity or an instantaneous velocity.
