Answer:
0.076 kg
Explanation:
The force created by gravity can be found using mass x (9.8 m/s^2).
mg=0.750 N
m(9.8) = 0.750
Multiply both sides by 9.8: m = 0.076 kg
I would say Option B) because Option C) is wrong since matter cannot be created. A closed system does not exchange matter so it's not Option D). Since an island is an isolated area, Option A) is wrong.
Given the increased current, the strength of the magnetic field around the wire carrying the current increases to 0.008T
<h3>What is the strength of the magnetic field if the current is changed to 40 A ?</h3>
Given that;
First scenario
- Strength of magnetic field B = 0.004T
Second scenario
- Strength of magnetic field B' = ?
First, we determine the strength of the magnetic field.
B/I = B'/I'
0.004T/20A = B'/40A
B' = ( 0.004T × 40A ) / 20A
B' = 0.16AT / 20A
B' = 0.008T
Given the increased current, the strength of the magnetic field around the wire carrying the current increases to 0.008T
