The options are missing and they are;
A) the electric force increases because the balloon loses its charge.
B) the electric force increases because the distance increases.
C) the electric force decreases because the distance increases.
D) the electric force decreases because his hair loses its charge.
Answer:
Correct answer is option C - the electric force decreases because the distance increases.
Explanation:
The formula for electric force is;
F = k•q1•q2/r²
Where;
K is coulombs constant
q1 and q2 are particle charges
r is distance
So,looking at the formula given earlier, if we increase the distance, the denominator will increase and thus the Force will decrease.
So the correct option is option C
Answer:
The difference between the Electrolyte and Non-Electrolyte are given in the explanation part.
Explanation:
- ELECTROLYTES are salts or molecules which ionize in solution fully.
- Electrolyte solutions thus conduct electricity readily.
whereas
- NON ELECTROLYTES in water do not dissociate from ions,
- non-electrolyte solutions do not conduct electricity.
Answer:
d = 5.10 m
Explanation:
As we know that here on the plane of the inclined there is no frictional force
So in these cases we can say that total mechanical energy will always remains conserved
so here we can say that
spring potential energy = gravitational potential energy of the block
as we know from the formula
now plug in the values in it
now as we know that the angle of inclination is 60 degree and height raised is 4.42 m
so here maximum distance moved along the inclined plane will be
Answer:
Induced EMF,
Explanation:
Given that,
Radius of the circular loop, r = 5 cm = 0.05 m
Time, t = 0.0548 s
Initial magnetic field, 
Final magnetic field, 
The expression for the induced emf is given by :
= magnetic flux
So, the induced emf in the loop is 0.0143 volts. Hence, this is the required solution.
