The average speed of the car is
(the mile marker he passes at the end of the 1.75 h) minus 115
divided by
(1.75 hours) .
The unit is 'miles per hour'.
Answer:a force of attraction exerted by each particle of matter in the universe on every other particle
Explanation:gravitation describes the attractive force between any two masses
Four electrons are placed at the corner of a square
So we will first find the electrostatic potential at the center of the square
So here it is given as

here
r = distance of corner of the square from it center



now the net potential is given as


now potential energy of alpha particle at this position

Now at the mid point of one of the side
Electrostatic potential is given as

here we know that



now potential is given as


now final potential energy is given as

Now work done in this process is given as



Answer:
Explanation:
First of all, we analyze the system of blocks before starting to move.
Hence, the incline angle θ for which both blocks begin to slide is 10.20°.
Now, if we do a free body diagram of block A we have that after the block moves, the spring force must be taken into account.

Where:



Therefore, the required stretch or compression in the connecting spring is 0.10 ft.
I hope it helps you!
