Answer:

D. The resistance increases.

Explanation:

Resistance of a wire is R = ρL/A, where ρ is the resistivity of the wire, L is the length, and A is the cross sectional area.

As L increases, R increases.

A 10-N force is needed to move an object with a constant velocity of 5.0 m/s. What power must be delivered to the object by the
vagabundo [1.1K]

The power that must be delivered to the object by the force is 50 W

Power is defined as the rate of doing work. The power of an object in relation to the force and velocity is given by the following equation:

Power (P) = Force (F) × velocity (v)

P = F × v

From the question given above, the following data were obtained:

  • Force (F) = 10 N
  • Velocity (v) = 5 m/s
  • Power (P) =?

P = F × v

P = 10 × 5

<h3>P = 50 W </h3>

Thus, the power that must be delivered to the object by the force is 50 W

A proton is confined within an atomic nucleus of diameter 3.60 fm. part a estimate the smallest range of speeds you might find f
Cerrena [4.2K]
The answer for this problem would be:
Assuming non-relativistic momentum, then you have: 
ΔxΔp = mΔxΔv = h / (4) 
Δv = h / (4πmΔx) 
m ~ 1.67e-27 h ~ 6.62e-34,Δx = 4e-15 --> 
Δv ~ 6.62e-34 / (4π * 1.67e-27 * 4e-15) ~ 7,886,270 m/s ~ 7.89e6 m/s 
That's about 1% of the speed of light, the assumption that it's non-relativistic.

The compressor on an air conditioner draws 66.1 a when it starts up. the start-up time is about 0.388 s. how much charge passes
Ierofanga [76]
The current intensity is defined as the amount of charge flowing through a certain point of a wire divided by the time interval:
I= \frac{Q}{\Delta t}
where Q is the charge and \Delta t is the time. Re-arranging the formula, we have
Q=I \Delta t

for the compressor in our problem, the intensity of current is I=66.1 A, while the time is \Delta t= 0.388 s, so the amount of charge that crosses a certain point of the circuit during this time is
Q=I \Delta t=(66.1 A)(0.388 s)=25.65 C
