Luda [366]3 years ago

Answer:

B) Decrease

Explanation:

Resistance offered due to inductor in any AC circuit is given as

X_L = \omega L

here we know that

\omega = angular frequency

\omega = 2\pi f

now by ohm's law we know that

i = \frac{V}{X}

here we have

i = \frac{V}{\omega L}

so current is inversely depends on the frequency of AC

so if frequency is increased then the current will decrease

An object is in simple harmonic motion. Find an equation for the motion given that the frequency is 3⁄π and at time t = 0, y = 0
Delicious77 [7]

Answer: y(t)= 1/π^2 sin(6*π^2*t)

Explanation: In order to solve this problem we have to consider the general expression for a harmonic movement given by:

y(t)= A*sin (ω*t +φo) where ω is the angular frequency. A is the amplitude.

The data are: ν= 3π; y(t=0)=0 and y'(0)=6.

Firstly we know that 2πν=ω then ω=6*π^2

Then, we have y(0)=0=A*sin (6*π^2*0+φo)= A sin (φo)=0 then φo=0

Besides y'(t)=6*π^2*A*cos (6*π^2*t)

y'(0)=6=6*π^2*A*cos (6*π^2*0)

6=6*π^2*A then A= 1/π^2

Finally the equation is:

y(t)= 1/π^2 sin(6*π^2*t)

How does genetic variation prevent environmental factors from wiping out a population?
ludmilkaskok [199]
With more genetic variations, the more adaptations will be developed that will help the population survive the changing environment.
For example, if an environment starts to grow lighter fields, a population will start to develop genetic variation that will help camouflage the animal. Like, make the animal start to have lighter skin to camouflage.

If the torque required to loosen a nut on the wheel of a car has a magnitude of 40.0Nm, what minimum force must be exerted by a
abruzzese [7]

Explanation:

Minimum force means that the force should be applied at a 90° angle from the wrench.

40.0Nm / (0.30m) = 133.33N.

The mimumum force is 133.33N.
