Energy Transformations Examples. An energy transformation is the change of energy from one form to another. Energy transformations occur everywhere every second of the day. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, electromagnetic, sound, and chemical.

Why do you think there are so many more autotrophs than consumers on Earth?<br> Helppp

goldfiish [28.3K]

There are many Autotrophs than consumers because : Autotrophs are the bases of any food chain/web

<h3>Function of Autotrophs </h3>

Autotrophs capture the energy required for every food chain or web from which sustains other organisms in the food chain form sunlight and chemicals. Also there is always more biomass present in the lower levels of the trophic system as biomass decreases as we move up the food chain.

Since autotrophs are producers, for a healthy food chain there would be more autotrophs than consumers.

Hence we can conclude that There are many Autotrophs than consumers because : Autotrophs are the bases of any food chain/web

The rainbow of visible colors in the electromagnetic spectrum varies continuously from the longest wavelengths (the reddest colo

Bogdan [553]

Answer:

$4.58\times 10^{14}Hz$ $5.825\times 10^{14}Hz$ $6.31\times 10^{14}Hz$

Explanation:

We know that there is a relation between the speed of light ,frequency and wavelength.This relation can be given as $v=\nu \lambda$ where v is speed of light $\nu$ is frequency of light $\lambda$ is wavelength of light

In first case we have given λ=655 nm

so using formula $v=\nu \lambda$

$3\times 10^8=655\times 10^{-9}\times \nu$

$\nu =4.58\times 10^{14}$ Hz

In second case we have wavelength 515 nm so by using above formula

$3\times 10^8=515\times 10^{-9}\times \nu$

$\nu =5.825\times 10^{14}\ Hz$

In third case we have wavelength 475 nm

so $3\times 10^8=475\times 10^{-9}\times \nu$

$\nu =6.31\times 10^{14}Hz$

In an electromagnetics lab, you are studying two coils which have a mutual inductance of M=300 mH. Suppose that the current in t

Firdavs [7]

Answer:

Explanation:

Given that,

The mutual inductance of the two coils is

M = 300mH = 300 × 10^-3 H

M = 0.3 H

Current increase in the coil from 2.8A to 10A

∆I = I_2 - I_1 = 10 - 2.8

∆I = 7.2 A

Within the time 300ms

t = 300ms = 300 × 10^-3

t = 0.3s

Second Coil resistance

R_2 = 0.4 ohms

We want to find the current in the second coil,

The same induced EMF is in both coils, so let find the EMF,

From faradays law

ε = Mdi/dt

ε = M•∆I / ∆t

ε = 0.3 × 7.2 / 0.3

ε = 7.2 Volts

Now, this is the voltage across both coils,

Applying ohms law to the second coil, V=IR

ε = I_2•R_2

0.72 = I_2 • 0.4

I_2 = 0.72 / 0.4

I_2 = 1.8 Amps

The current in the second coil is 1.8A
