Answer:
0.014 kg
Explanation:
trust me its right i took the assessment and got 100%. :)
As per the question,the current amplitude is given as i= -2.7 micro ampere
i.e -2.7 ×
as per the question the time is given as t=1.15s
we know that 
hence q=i×t
hence the total charge passing through this point is given as
q= -2.7×
× 1.15
= -3.105×
we know that q=ne where n is the number of electrons and e is the charge of electron
we have e= -1.602×
coulomb
hence number of electrons n=
= 3.105×
×
=1.93820×
<span>Physicists use certain units to measure heat energy and electrical energy:
- Joule (Watt sec )
- Watt - hour
- Kilowatt- hour
- Calorie
Hope this helps!

Distance = velocity (or speed) x time
so, distance = 0.30 meters.min x 15 mins
distance = 4.5 meters
Answer:
No.
Explanation:
The force that two particle experience is inversely proportional to the sqare of the distance, this is:
for a distance D
If we move them so that D is doubled:
= 
Then the force they experience is one fourth of the original.
