Which has more kinetic energy, a 40 kg cheetah running at 25 m/s or a 4,000 kg elephant moving at 2 m/s? How much more energy do

denis23 [38]

Answer:

1st case; mass=40 kg

v=25m/s

K.E.=1/2[40][25]^2=12,500 J

2nd case; mass=4,000 kg

v=2 m/s

K.E.=1/2[4000][2]^2=8000J

in case 1 Kinetic energy is greater.

A conducting coil of 1750 turns is connected to a galvanometer, and the total resistance of the circuit is 30 Ω. The area of eac

Sati [7]

Answer:

0.31 T

Explanation:

N = 1750

R = 30 ohm

A = 5 x 10^-4 m^2

B1 = 0 T

q = 9 x 10^-3 C

Let the magnetic field is B ad the time is t.

B2 = B

Use the Faraday's law of electromagnetic induction

e = dФ / dt

i R = N x A x (B2 - B1) / t

i x R / t = N x A x B

q x R = N x A x B

9 x 10^-3 x 30 = 1750 x 5 x 10^-4 x B

B = 0.31 T

When decreasing electromagnetic radiation there is a(n)_______relationship between wavelength and frequency and the greater the

IceJOKER [234]

Answer:

Inverse proportion, greater

Explanation:

The relation between wavelength (λ) and frequency (ν) is given by

$\nu = \frac{c}{\lambda }$

Where $c$ speed of light in vacuum.

We can see from this equation that wavelength and frequency are related inversely.

Now,

$E= h \nu$

Where 'E' is energy of electromagnetic radiation and 'h' is Planck's constant.

We can see from this equation that greater frequency (ν) will give greater electromagnetic radiation (E). As they are directly proportional.

Hence,

When decreasing electromagnetic radiation there is a(n) Inverse proportion relationship between wavelength and frequency and the greater the frequency, the greater energy the electromagnetic radiation has
