Katyanochek1 [597]

Answer:

3×10⁹ W

Explanation:

Power = work / time

Power = force × distance / time

Power = force × velocity

P = Fv

P = (10⁶ N) (3000 m/s)

P = 3×10⁹ W

How do convection currents influence plate tectonics

jarptica [38.1K]

Answer and Explanation:

Convection happens when particles with a great deal of warmth vitality in a fluid or gas move and replace particles with less warmth vitality.

Lighter (less thick), warm material ascents while heavier (progressively thick) cool material sinks. It is this development that makes course examples known as convection flows in the environment, in water, and in the mantle of Earth.

Huge amount of pressure and heat inside the earth causes the hot magma to stream in convection ebbs and flows. These flows cause the development of the structural plates that make up the world's outside.

Plates at our planet's surface move in view of the extreme warmth in the Earth's center that causes liquid shake in the mantle layer to move.
It moves in an example considered a convection cell that structures when warm material ascents, cools, and in the long run sink down. As the chilled material sinks off, it is warmed and rises once more.

A student solving a physics problem for the range of a projectile has obtained the expression r= v20sin(2θ)g where v0=37.2meter/

DedPeter [7]

Formula of range is given by

$R = \frac{v_o^2 sin2\theta}{g}$

here given that

$v_0=37.2m/s$

θ=14.1∘

$g=9.80m/s^2$

now by above equation

$R = \frac{37.2^2 sin2*14.1}{9.80}$

R = 66.7 m

so range will be 66.1 m

As a new electrical technician, you are designing a large solenoid to produce a uniform 0.160-T magnetic field near the center o

MariettaO [177]

Answer:

Current = 32.6 A

Explanation:

Magnetic field = B = 0.160 T

No. of turns of coil = N = 4300

Length of the solenoid = L = 1.10 m

Current required depends on the B, L , N and the magnetic permeability μ₀

B = μ₀ N I / L

⇒ Current = I = B L / μ₀N = ( 0.160 ) ( 1.10) / (4π × 10⁻⁷)(4300)

= 32.6 A
