The initial equivalent resistance of the circuit is
which means
Therefore the initial current in the circuit is
When the new resistor of
is added to the circuit in parallel, the new equivalent resistance of the circuit is
from which we find
This means that the equivalent resistance of the circuit has decreased, and the new current is
which means that the current in the circuit has increased.
Answer:
q = -2.19 x 10⁻⁵ C
Explanation:
Given;
mass of the particle, m = 1.5 g = 0.0015 kg
magnitude of electric field, E = 670 N/C
Electric field is given by;
where;
q is the magnitude of the
f is the force of the charge
f = mg
Since the electric field is acting downward, the force on the charge must be acting upward. Therefore, the charge must be negative
q = -2.19 x 10⁻⁵ C
Answer:0.10283 J
Explanation:
Given
mass of block(m)=0.0475 kg
radius of track (r)=0.425 m
when the Block is at Bottom Normal has a magnitude of 3.95 N
Force acting on block at bottom
u=5.583 m/s
At top point
v=3.188 m/s
Using Energy conservation
i.e. 0.10283 J of energy is wasted while moving up.
