I cannot see all the questions, what is 18,19 and 21? (:
Answer:
6.77 minutes
Explanation:
172 degree - 78 degree = (185 degree - 78 degree)e−2 k
=> 94 = 107
e−2 k => 94 ÷ 107
k => ln (94÷107) / 2
147 - 78 = (185 - 78)e ^[ln (94÷107) / 2]
=> 69 = 107 e^ [ln (94÷107) / 2]
e^[ln (94÷107) / 2] =69 ÷ 107
=> t = [ln (69 ÷ 107)] ÷ [ln (94÷107) / 2]
t=> -0.4387 ÷ -0.0648
t => 6.77 minutes.
Therefore, the final answer to the question is 6.77 minutes.
It should be an Electrical conductor, since conductors allow for movement of electrons from one point to another.
Answer:
(C) Equal to 1.44 watt
Explanation:
We have given energy dissipated through the resistor = 1.44 watt
We have to find the energy supplied by the battery
From Telegence theorem we know that energy dissipated through resistor is equal to the energy supplied
As energy supplied is given as 1.44 watt
So energy supplied by the battery will be equal to 1.44 watt
So option (c) will be correct answer
