Answer:
A. The force between the wires Is attractive, this is because there are two wires of equal current flowing in the same direction thus using the right hand rule the force vectors of the two wires point to each other.
B: see attached file for explanation
Explanation:
The greatest difference between high and low tide is around New Moon and Full Moon. During these Moon phases, the solar tide coincides with the lunar tide because the Sun and the Moon are aligned with Earth, and their gravitational forces combine to pull the ocean's water in the same direction.
Your answer is B Full moon
Anxiety Disorder is treatable, not curable.
I think it is the last choice because light can travel as waves but it can also travel through a vacuum in an airless space.
Answer:
<h2>A. twice</h2>
Explanation:
Spring potential Energy is expressed as E = 1/2 ke²
k = spring constant
e = displacement of the string
If Spring A has a spring constant of 100 N/m and displacement of 0.2m, the spring potential energy will be;
= 1/2 * 100 * 0.2²
= 50 * 0.04
= 2Joules
If spring B has a spring constant of 200 N/m and displacement of 20m, the spring potential energy will be;
= 1/2 * 200 * 0.2²
= 100 * 0.04
= 4Joules
From the values gotten, it can be seen that the spring potential energy of spring B is twice that of A
