Comparing and contrasting two organisms is comparative anatomy. (A)
Answer:
N = 25795 loops
Explanation:
The magnetic field of a solenoid can be calculated by using the following formula:
where,
N = No. of loops = ?
B = Magnetic Field = 0.78 T
L = Length of solenoid = 32 cm = 0.32 m
I = Current = 7.7 A
μ = permeability of free space = 4π x 10⁻⁷ N/A²
Therefore,
<u>N = 25795 loops</u>
Answer: B
Explanation: I just took the quiz and got it right
Answer:
It is given that the weight of the person is 102 N
We have the force that shall be needed to being the man out in minimum amount of time shall correspond to the maximum tension that can be developed
Thus using Newton's second law we obtain the acceleration that the man shall attain
Now using second equation of kinematics to obtain time 't' we get
