To solve the problem, we can use Ohm's law, which states that
where
V is the voltage
I is the intensity of current
R is the resistance
Using the data of our problem, I=4 A and
, we find the voltage:
Answer:
F = 2.3 x 10⁻⁸ N
Explanation:
Given,
The mean distance between the electron and the nucleus, x = 1 x 10⁻¹⁰ m
The number of protons present in the nucleus of the hydrogen atom is 1.
The charge of the proton and electron, q = 1.602 x 10⁻¹⁹ C
Since they have opposite charges, the force between them is attractive,
The coulomb law of force between two charges is given by the formula,
<em> </em>
= 9 x 10⁹ Nm²C⁻²
Substituting the values in the above equation
F = 9 x 10⁹ X (1.602 x 10⁻¹⁹)² / (1 x 10⁻¹⁰)²
= 2.31 x 10⁻⁸ N
Hence, the force between the nucleus and electron of hydrogen atom is, F = 2.3 x 10⁻⁸ N
Answer:
Because it is the result of two more fundamental units, a derived unit is termed that. For volume, the cubic meter (m³) is the fundamental unit of area. Any number that cannot be measured directly with any equipment is referred to as a derived unit. For example, we can't quantify a substance's density using a rule, scale, or bucket.

D.) Asteroids
Asteroids are large rocks that orbit the sun. They aren't considered planets since they are smaller.
