Answer:
Option C
Explanation:
From the question we are told that:
Mass 
Radius 
Time 
Generally the equation for Tension is mathematically given by



Therefore
, toward the center of the circle
Option C
Answer:
Stars are forming in the spiral arms so there are high mass, hot, blue stars in the arms.
Explanation:
Answer:
use a reusable source of energy such as hydro power
Explanation:
use renewable energy it saves the environment and does not create global warming
To solve the problem, start by applying the concepts related to current in an RL circuit. The current is defined exponentially and using Ohm's law we can put the initial current in terms of the voltage and resistance. Consecutively with the calculated time constant we can find the respective inductance. For the second part we will apply the electrical potential energy connectors to find the amount of stored energy.
PART A)





Inductance can be defined then,



PART B) Now the energy is given under the terms:



Therefore the energy stored in the coil at this same moment is 0.0002727J
