Volcanic islands, Mountain ranges

Explanation:

A convergent margin is plate boundary in which plates comes together. There are different types of interactions that occurs around a place where plate converges.

An ocean-continent convergence creates a subduction zone in which the denser oceanic plate sinks beneath the less dense continental crust.
As the oceanic plate begins to subside, it can melt and form chains of volcanic island within the riding continents.
Also, where two plates of equal densities converge, none of them subsides and this leads to upbuilding.
The product can be seen as extensive mountain ranges on earth like the Andes and Himalayas.

A long solenoid that has 1 200 turns uniformly distributed over a length of 0.420 m produces a magnetic field of magnitude 1.00

Fantom [35]

Answer:

<h2>The current required winding is $2.65*10^-^2 mA$ </h2>

Explanation:

We can use the expression B=μ₀*n*I-------1 for the magnetic field that enters a coil and

n= N/L (number of turns per unit length)

Given data

The number of turns n= 1200 turns

length L= 0.42 m

magnetic field B= 1*10^-4 T

μ₀= $4\pi*10^-^7 T.m/A$

Applying the equation B=μ₀*n*I

I= B/μ₀*n

I= B*L/μ₀*n

$I= \frac{1*10^-^4*0.42}{4\pi*10^-^7*1.2*10^3 }$

$I= 2.65*10^-^2 mA$

There is a small scratch on a disco record located 14.5 cm from the center. When played, the scratch makes the record skip 30 ti

LuckyWell [14K]

Answer:

The linear speed of scratch is 45.55 cm/dec

Explanation:

The scratch located from the center at radial distance = 14.5 cm.

Each minute the skip of scratch when disco record played = 30 times

Since, the scratch on the disc start revolving when disc is played and in one minute the scratch revolve 30 times. Therefore, the revolution = 30 RPM

Below is the calculation of linear speed of the scratch.

$Angular \ velocity, \ w \ = \frac{2 \pi \times RPM}{60} \\$

$w = \frac{2 \pi \times 30}{60} = \pi \ rad/dec \\$

$Linear \ velocity = wr \\$

$r = radial \ distance \\$

$v = \pi \times 14.5 \\$

$v = 45.55 cm/dec$

If nothing is faster than light, how did the dark get there first? O.o

erastova [34]

Nothing is faster than light. Dark is the absence of light, or indeed anything at all. ... Darkness came before light, so light had to be created to get there. It's like turning on s flashlight in a dark room: the darkness is already there, and an outside source (you/the flashlight) needs to create light.
