Electrostatic potential energy of a system of charge is given by
![U = \frac{kq_1q_2}{r}](https://tex.z-dn.net/?f=U%20%3D%20%5Cfrac%7Bkq_1q_2%7D%7Br%7D)
here we have
= two charges of different magnitudes
r = distance between charges
so here we can see that electrostatic potential energy will depends upon the product of two charges and inversely depends upon the distance between the two charges
So here we can say that the electrostatic potential energy of two charges will be same and equal to each other
Assuming the object is on earth the objects weight would be equal to its mass multiplied by the gravitational field constant
mass=22kg
g=9.80665N/kg
weight=(22 kg) (9.80665 N/kg)=215.7463N
generally g is rounded to be 10 N/kg so for any question where it asks the weight given the mass just multiply by 10 and that should suffice. In this case the answer would be 220 N
Answer:
They use noise control, creating a wave that negates outside or ambient sound and replaces it with the desired sound that listeners request.
Explanation:
I hope this helped
Answer:
3.3m/s
Explanation:
You first get the total time (80 + 70 = 150s).
Then you would find the displacement of the truck. To do that you would do component method (vector addition), so since its a right triangle (North and East), displacement is 400^2 + 300^2 = d^2.
d= 500m.
So now that you have displacement and time, you can find the velocity:
v=d/t
v=500/150
v=3.3
Answer:
The object starts away from the origin and then moves toward the origin at a constant velocity. Next, it stops for one second. Finally, it moves away from the origin at a greater constant velocity.
