Answer:
Current X has a lower potential difference than Current Y.
Explanation:
The table is as follows:
Current Volts (V)
W 9.0
X 1.5
Y 3.0
Z 4.5
There are two quantities represented in the table:
1) Current: the current is the rate of flow of electric charge in a circuit. It is given by
where q is the amount of charge that passes a given point of a circuit in a time t. It is measured in Ampere (A).
2) Potential difference: the potential difference is the difference in electric potential between two points of a circuit. The potential difference is responsible for "pushing" the electrons through the circuit and producing a current. It is measured in Volts (V).
From the table, we see that
Current X has a lower potential difference (1.5 Volts) than Current Y (3.0 Volts)
So the correct choice is
Current X has a lower potential difference than Current Y.
Hello!
A stretched spring has 5184 J of elastic potential energy and a spring constant of 16,200 N/m. What is the displacement of the spring?
0.57 m
0.64 m
0.80 m
1.25 m
Data:
For a spring (or an elastic), the elastic potential energy is calculated by the following expression:
Where k represents the elastic constant of the spring (or elastic) and x the deformation or displacement suffered by the spring.
Solving:
Answer:
The displacement of the spring = 0.8 m (or 0.80 m)

Answer:
294J
Explanation:
The work done by gravity is independent of the horizontal distance. It is only dependent on the vertical height of 15m above its initial position.
The work done against gravity is given by
Given;
m = 2.0kg
Hence;
