Answer:
Explanation:
First, we will calculate the inductance of the solenoid by using the following formula:
where,
L = self-inductance of solenoid = ?
μ₀ = permeability of free space = 4π x 10⁻⁷ N/A²
A = Cross-sectional area = 30 cm² = 3 x 10⁻³ m²
N = No. of turns = 2000
l = length = 65 cm = 0.65 m
Therefore,
Now, we will use Faraday's law to calculate the rate of change of current:
Answer:
There are two main types of graphs in motion, namely displacement-time graph and velocity-time graph.
(GABS) Overnight, all of the particles settled down to the bottom , and the larger particles were on the bottom and the smaller particles were on the top. Therefore, clay was on top, hummus was in the middle, and soil was on the bottom.
Particles dissolve is an unique way
<span>An endothermic reaction takes heat from it's environment. When you increase the temperature of the environment in which the endothermic reaction is taking place, the forward reaction will be favored and more products will form. The answer is B.</span>
