Answer:

v₁ / v₂ = √μ ₂/μ ₁

Explanation:

The speed of a traveling wave on a string is given by

v = √ T /μ

Where v is the speed of the wave, T the tension and μ is the linear density of the string

Let's apply this equation to our case

v₁ = √ T / μ ₁

v2 = √ T /μ ₂

If the voltage of the two systems is the same

T = v₁² μ₁ = v₂² μ₂

We cleared

v₁² / v₂² = μ₂ / μ₁

v₁ / v₂ = √μ ₂/μ ₁

Which electromagnetic wave has wavelengths just longer than visible light? A. infrared radiation B. ultraviolet radiation C. mic

Nady [450]

Answer:

The correct answer is A and B

Explanation:

Light is part of the spectrum of electromagnetic energy along with radio waves, microwaves, infrared, visible light, ultraviolet, X rays and Gamma rays.

Radio waves and microwaves lie on one end of the spectrum, the longer end of electromagnetic energy.

X rays and Gamma rays have very short wavelengths .

I hope it helps!

-What is the potential different drop across an electric hot plate that draws 5A when its hot resistance?

Bumek [7]

Answer:

Potential difference across the plate is 25 R

Explanation:

Let the resistance of he hot plate is R

Current flowing in the plate is 5 A

We have to find the potential difference across the hot plate.

Potential difference across the plate is given by $V=i^2R$ , here i is current and R is resistance

Therefore potential difference across plate

$V=5^2\times R=25R$

A rescue helicopter is hovering over a person whose boat has sunk. One of the rescuers throws a life preserver straight down to

Arturiano [62]

Answer:

13.125 m

Explanation:

b) The quantity which are known as

Initial velocity of life preserver, u = 1.40 m/s

time to reach, t = 1.50 s

final velocity of the life preserver, v = 0 m/s

acceleration due to gravity = 9.8 m/s²

a) height of the preserver above water

using equation of motion

$h = u t + \dfrac{1}{2}gt^2$

$h = 1.4\times 1.50 + \dfrac{1}{2}\times 9.8\times 1.5^2$

h = 13.125 m

Hence, the height from where preserver is thrown is equal to 13.125 m
