A. is the answer for this
Answer:
The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increase. Potential energy is energy that is stored in an object or substance.
Explanation:
An object can store energy as the result of its position. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly, a drawn bow is able to store energy as a result of its position. When assuming its usual position (i.e., when not drawn), there is no energy stored in the bow. Yet when its position is altered from its usual equilibrium position, the bow is able to store energy by virtue of its position. This stored energy of position is referred to as potential energy. Potential energy is the stored energy of position possessed by an object.
Answer:
The value of the maximum charge the cloud can hold Q = 177.08 coulomb
Explanation:
Given data
Electrical Field E = 4 ×
the maximum charge the cloud can hold is given by
Q = E A x ---- (1)
where A = area = 5 ×
x = electrical Permittivity of air = 8.854 ×
Q = (4 × ) (5 × ) ( 8.854 × )
Q = 177.08 coulomb
This is the value of the maximum charge the cloud can hold.
Answer:
The correct answer is D, V =0
Explanation:
The electrical potential due to a point charge is given by
V = k ∑
Let's apply this equation to our case
V = k (Q / r - Q / r)
V = 0
Since the two charges have the same magnitude and are of opposite signs and the distance from any corner to the center of the square from side to is
r = √2 a/2
Therefore all distances are equal
The correct answer is D
Newton’s Second Law: Force = mass times acceleration.
F = 0.145 * 130
You would multiply to find the force required, not divide. Hope this helps!
