Answer:
The value is
Explanation:
From the we are told that
The radius of the sphere is
The temperature is
The average temperature of the rest of the universe is
Generally the change in entropy of the entire universe per second is mathematically represented as
Here is the entropy of the rest of the universe which is mathematically represented as
Here Q is the quantity of heat radiated by the star which is mathematically represented as
Here is the Stefan-Boltzmann constant with value
=>
=>
So
=>
Here is the entropy of the rest of the universe which is mathematically represented as
=>
=>
So
=>
Answer:
0.00225 N/m
Explanation:
Parameters given:
Current in first wire, I(1) = 15A
Current in second wire, I(2) = 15A
Distance between two wires, R = 1cm = 0.01m
The force per unit length between two current carrying wires is:
F/L = μ₀I(1)I(2)/2πR
μ₀ = 4π * 10^(-7) Tm/A
F/L = [4π * 10^(-7) * 15 * 15] / (2π * 0.01)
F/L = 2.25 * 10^(-3) N/m or 0.00225 * 10^(-3) N/m
Answer:
Option A
Multiplanar step-up to balance
Explanation:
Resistance training exercises are the exercises that cause the muscles to contract against an external resistance leading to an increase in strength and endurance. Resistance training increases muscle strength by making your muscles work against a weight or force. Considering the options given, it's only Multiplanar step-up to balance which is an example of a strength level resistance training exercise for legs.
the answer is increases concentrations of solids.

The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom. A good comparison of the nucleus to the atom is like a pea in the middle of a racetrack. (10-15 m is typical for the smaller nuclei; larger ones go up to about 10 times that.)
