Answer:
The power dissipated by the resistor can be calculated as .
Explanation:
- Joules heating law states that any conductor passed with the electric current produces heating effect which is the electric power loss.
- The given circuit has,
resistor (the unit is wrong i question because resistor's unit is ohm not Ampere).
- Current flowing through the circuit is
.
- By using joules heating theory,
,
,
.
- So the power dissipated by the resistor in the circuit is 300 W.
Answer:
v₀ₓ = 28.6 m / s
Explanation:
This is a missile throwing exercise
y = t - ½ g t²
as the dart is thrown horizontally the vertical velocity is zero (I go = 0)
y = - ½ g t²
t =
let's calculate
t =
t = 0.175 s
the expression for horizontal displacement is
x = v₀ₓ t
v₀ₓ = x / t
v₀ₓ = 5.00 / 0.175
v₀ₓ = 28.6 m / s
