Weight changes due to the gravitational pull in mars,basically gravity
Resistance-1 = (voltage-1) / (current-1) =
(12 V) / (0.185 A) = 64.9 ohms .
Resistance-2 = (voltage-2) / (current-2) =
(90 V ) / (1.25 A) = 72 ohms .
The resistance changed between situation-1 and situation-2 .
How did that happen ?
Power = (voltage) x (current)
Power-1 = (12) x (0.185) = 2.22 watts
Power-2 = (90) x (1.25) = 112.5 watts
The poor resistor dissipated 51 times as much power during
the second trial. It got all heated up, and its resistance went
through the roof.
Carbon resistors behave nicely and reliably, until you try to
toast bread or light up your bedroom with them.
Answer:
34.75m
Explanation:
Parameters given:
Net force, F = 320N
Work done by net force, W = 4700 N
Angle, θ = 65º
Work done at an angle is given as:
W = F * d * cosθ
Where d = distance travelled
θ is the angle between the force and the direction of motion.
Therefore,
4700 = 320 * d * cos65
=> d = 4700/(320 * cos65)
d = 34.75 m
