Answer:
2.40 x 10⁻¹³ C
Explanation:
= number of electrons = 6.25 x 10⁶
= charge on electron = - 1.6 x 10⁻¹⁹ C
= number of protons = 7.75 x 10⁶
= charge on proton = 1.6 x 10⁻¹⁹ C
Net charge is given as
Q = +
Q = (- 1.6 x 10⁻¹⁹) (6.25 x 10⁶) + (1.6 x 10⁻¹⁹) (7.75 x 10⁶)
Q = 2.40 x 10⁻¹³ C
Answer:
The example of the center of the gravity is the middle of a seesaw
Explanation:
I hope this will help you and plz mark me brainlist
it has a high density. since density is mass divided by volume, if you are dividing a large mass by a small volume it will have a high density
Answer:
The current in primary coil is 2.08 A.
Explanation:
Given that,
Power = 500 W
Voltage = 16 kV
Number of turns = 80000
We need to calculate the number of current
Using formula of voltage
Put the value into the formula
We need to calculate the current in secondary coil
Using formula of current
We need to calculate the current in primary coil
Put the value into the formula
Hence, The current in primary coil is 2.08 A.
Answer:
current = 2.67 A
Explanation:
we have given,
Q(t) = t³− 2t² + 4t + 1
to find I at t = 0.7s
we know
so,
current at t= 0.7s
I = 2.67 A
hence, current comes out to be 2.67 A
