Charge= Protons- electrons
Charge= 35p-37e= -2
This Ion will have a charge of -2<span>. </span>
1 watt = 1 joule per second = 1 newton meter per second = 1 kg m2 s-3
Answer:
E) d/sqrt2
Explanation:
The initial electric force between the two charge is given by:

where
k is the Coulomb's constant
q1, q2 are the two charges
d is the separation between the two charges
We can also rewrite it as

So if we want to make the force F twice as strong,
F' = 2F
the new distance between the charges would be

so the correct option is E.
Answer:5
Explanation:
Decimal :2
Significant notation :2.4632× 10^2
Answer:
500 Pa
Explanation:
Convert given units to SI:
100 dyne = 0.001 N
0.02 cm² = 2×10⁻⁶ m²
Pressure = force / area
P = 0.001 N / (2×10⁻⁶ m²)
P = 500 Pa
