Answer:
Hey mate
Your answer will be <u>5 N</u><u> </u><u>Upwards</u><u>.</u><u> </u>
I will explain this to you.
In the attachment we can see that there are two forces acting on the object from the same side. And we know that when force acts from the same direction. Then the total force
=> sum of all the forces in that particular direction.
I hope you got it :)

Answer:
- The total distance traveled is 28 inches.
- The displacement is 2 inches to the east.
Explanation:
Lets put a frame of reference in the problem. Starting the frame of reference at the point with the 0-inch mark, and making the unit vector pointing in the west direction, the ant start at position
Then, moves to
so, the distance traveled here is
after this, the ant travels to
so, the distance traveled here is
The total distance traveled will be:
The displacement is the final position vector minus the initial position vector:
This is 2 inches to the east.
Answer:
The pressure is
Explanation:
From the question we are told that
The initial pressure is
The temperature is
Let the first volume be Then the final volume will be
Generally for a diatomic gas
Here r is the radius of the molecules which is mathematically represented as
Where are the molar specific heat of a gas at constant pressure and the molar specific heat of a gas at constant volume with values
=>
=>
=>
=>
Answer:
the final speed of the barrier would be 40m/s
Explanation:
Hello, I think I can help you with this.
the momentum is given by:
P=m*v, where P is the momentum, m is the mass of the object and v is the speed of the object.
if the momentum is transferred completely it means that the barrier will have the same amount of momentum, in other terms
momentum of the moped=momentum of the barrier
mass of the moped*speed of the moped=*speed of the barrier
let's isolate the final speed of the barrier
final speed of the barrier is
so, the speed is 40 m/s
