Answer:
Suck up the iron using the electromagnet.
Explanation:
Iron is magnetic and copper is not. So copper will be
unaffected by the magnet. After extracting the iron,
open the switch. The electromagnet will lose its
magnetism and the iron fillings will fall off..
Answer: because the air currents move upwards so the hot air fills up the whole room. Similarly if the air conditioner is placed neer the ceiling because it gives cool air
<span> Weight = mass x acceleration
Earths acceleration is 9.8 m/s*2
1 kg = 2.2 lbs, so 2.0 lbs x 1 kg/2.2 lbs = 0.91 kg
The bag would have a weight of 9.8 x 0.91 = 8.9 N
1. 8.9 x 1/6 = 1.5 N
2. 8.9 x 2.64 = 23.5 N
The mass of the bag at all three locations is 0.91 kg. Mass does not change, the different locations only change its weight. </span>
Answer
given,
capacitance = C = 3.4-µF
inductance = L = 0.08 H
frequency is expressed as
time period
after time T/4 current reach maximum
t = 8.2 x 10⁻⁴ s
t = 0.82 ms
b) using law of conservation
I = 0.010 A
I = 10 mA
