If the resistance doubles while the voltage stays the same, what effect will that have on the power?

Physics

The best formula to use for this question is

             Power = (voltage)² / R

So      Original power = (voltage)² / (original R)
and
           New power  =  (same voltage)² / (2 x original R)

That's equal to            (1/2) (voltage)² / (original R)

which is equal to    (1/2) (original power) .

So I guess the power decreases by half, and that's choice-B .

Suppose that a car weighing 4000 pounds is supported by four shock absorbers Each shock absorber has a spring constant of 6500 l
scoundrel [369]

Answer:

0.43622 seconds

0.9158 foot

-4.43 ffot/sec

Explanation:

we first find the period of oscillation

= 2π√w/gk

= 2π√4000/32x2600

= 2π√0.00481

= 2π0.0694

= 0.43622

b. we find the angular velocity

2π/T

= 2π/0.43622

= 14.41 rad/sec

we find displacement

rom the calculation in the attachment

Ф = -144.1

initial condition

1*cos(-144.1 rad)

= 0.9158 foot

initial velocity of the car

= (-1)(14.41)sin(ω(0)-144.1)

= -4.44 foot/sec

For each situation, identify when sound would travel faster and why?
Rudiy27
A. Outside on a summer day, there are less particles that the sound bounces off of (snow and wind absorb the sound)

B. Water, sound travels faster through denser objects. Water has a higher density than air.

C. High air pressure, sound moves faster through matter that is closer together. This can be said because sound can't travel through space. (There is no atmosphere and consistent particles in space for sound to go through)

D. A piece of steel, It's denser than wood and water.

E. 90% nitrogen and 10% helium, nitrogen is denser than helium so it will move faster
