Calculate the amount of gravitational potential energy at the top of each hill

Physics
1 answer:
Marizza181 [45]4 years ago
5 0
The gravitational potential energy has the formula:
PE = mgh
where PE is in joules
m is the mass of the object in kg
g is the acceleration due to gravity
h is the height in m

since you did not give the value of h, i cannot fully answer your quesstion.
PE = (58/1000 kg) (9.81m/s2) h
PE = 0.57h
just substitute the value of h in the equation

According to coulombs law, what will happen to the force between two charged particles if the magnitude are increased by 6 times
seropon [69]

Answer: The electrostatic force will be the same

Explanation:

According to Coulomb's Law, when two electrically charged bodies come closer, appears a force that attracts or repels them, depending on the sign of the charges of this two bodies or particles.  

In this sense, this law states the following:

"The electrostatic force F_{E} between two point charges q_{1} and q_{2} is proportional to the product of the charges and inversely proportional to the square of the distance d that separates them, and has the direction of the line that joins them"  

 

F_{E}= K\frac{q_{1}.q_{2}}{d^{2}}  (1)

Being K is a proportionality constant.  

Now, if each q_{1} and q_{2} are increased by 6, and the distance between them as well, we will have the following:

F_{E}= K\frac{6 q_{1}. 6 q_{2}}{(6d)^{2}}  (2)

F_{E}= 36 K\frac{q_{1}. q_{2}}{36d^{2}}  (3)

Simplifying:

F_{E}= K\frac{q_{1}.q_{2}}{d^{2}}  (4)

Comparing (1) with (4) we can see the electrostatic force is the same.

Please Help!<br><br><br>What is inertia? What does inertia depend on?
Lemur [1.5K]
Inertia is that quantity which depends solely upon mass. The more mass, the more inertia. Momentum is another quantity in Physics which depends on both mass and speed.
