Answer:
15 V
Explanation:
Electric potential is given as the product of Electric field and distance. Mathematically:
V = E * r
Where E = Electric field
r = distance = 6m
Electric field, E, is:
E = F / q
Where F = Electric force = 5N
q = Electric charge = 2C
Therefore, electric potential will be:
V = (F * r) / q
V = (5 * 6) / 2
V = 15V
Answer:
Explanation:
Time to cover first 100 km = 1 hour.
time remaining = 3.15 - 1 = 2.15 hour .
Time to cover next 42 km = 1 hour .
Time remaining = 2.15-1 = 1.15 hour.
Distance to be covered = 310 - 142
= 168 km
least speed needed = distance remaining / time remaining
= 168 / 1.15
= 146.08 km / h .
Whenever we move, we alter the rate at which we move into the future. This statement is true.
Answer:
1 ml/second is a small flow
Explanation:
Answer:
The induced current and the power dissipated through the resistor are 0.5 mA and .
Explanation:
Given that,
Distance = 1.0 m
Resistance = 3.0 Ω
Speed = 35 m/s
Angle = 53°
Magnetic field
(a). We need to calculate the induced emf
Using formula of emf
Where, B = magnetic field
l = length
v = velocity
Put the value into the formula
We need to calculate the induced current
Put the value into the formula
(b). We need to calculate the power dissipated through the resistor
Using formula of power
Put the value into the formula
Hence, The induced current and the power dissipated through the resistor are 0.5 mA and .
