Answer: 2a- 0.4167s
Explanation:
Given: distance= 5m, speed= 12m/s
Unknown: time
Equation: t= d/s
Substitution: t=5/12
t=0.4167s
Answer:
(a) 9.65 mH
(b) doubled
Explanation:
A = 6 cm^2 = 6 x 10^-4 m^2, l = 20 cm = 0.2 m, i = 2.8 A, N = 1600
(a) The formula for the self inductance of a solenoid is given by
L = μ0 N^2 A / l
L = 4 x 3.14 x 10^-7 x 1600 x 1600 x 6 x 10^-4 / 0.2
L = 9.65 x 10^-3 H
L = 9.65 mH
(b) As we observe that the inductance is proportional to the area so if the area is doubled, then inductance is also doubled.
Answer:
The DNA in bacteria exists as unpacked blobs.
The DNA in animals and plants are neatly packed.
<h3>EXPLAMATION :</h3>
I don't really have an explanation.
The DNA in animals and plants are neatly packed into chromosomes, whereas the DNA in bacteria exists as an unpacked blob in the cell
Answer: Hand span
Explanation: Hand span is not a standard unit.
Second is the unit of time.
Meter is the unit of length or distance covered by an object.
Gram is the unit of weight of an object.
Hand span is not a standard unit. This is because the size of hand varies from person to person. Hence, the correct option is (c) "hand span".
