Answer:

I have deduced that the answer is C) "The crust in Item A is found partially below sea level as compared to the crust in Item B."

Explanation:

This is because the crust in picture A has its crust slightly underneath sea level compared to picture B. I'd get more in-depth, but, I'm a bit too lazy. I believe this is to be learnt about in the future anyhow.(I believe)

A jet aircraft is traveling at 262 m/s in horizontal flight. The engine takes in air at a rate of 85.9 kg/s and burns fuel at a

Fittoniya [83]

Answer:

$F_T=60132.52N$

$P=15814852.76W$

Explanation:

From the question we are told that

Velocity of aircraft $V=263m/s$

Engine air intake rate $\triangle M_a=85.9kg/s$

Fuel burn rate $\triangle M_f =3.92kg/s$

Velocity of exhaust gas $V_e =921m/s$

Generally the Mass change rate of Rocket is mathematically given by

$\triangle M = \triangle M_a+\triangle M_f$

$\triangle M= 85.9+3.92$

$\triangle M=89.82kg/s$

Generally the Trust of the rocket is given mathematically by

$F_T=(\triangle M *V_e)-(dM_a/dt)*(V)$

$F_T=(89.82 *921)-(85.9)*(263)$

$F_T=60132.52N$

Generally the Rocket's delivered power is mathematically given by

Delivered power P

$P=V*F_T$

$P=263*60132.52N$

$P=15814852.76W.$

A man pushing a crate of mass

marin [14]

(a) The magnitude and direction of the net force on the crate while it is on the rough surface is 36.46 N, opposite as the motion of the crate.

(b) The net work done on the crate while it is on the rough surface is 23.7 J.

<h3>Magnitude of net force on the crate</h3>

F(net) = F - μFf

F(net) = 280 - 0.351(92 x 9.8)

F(net) = -36.46 N

<h3>Net work done on the crate</h3>

W = F(net) x L

W = -36.46 x 0.65

W = - 23.7 J

<h3>Acceleration of the crate</h3>

a = F(net)/m

a = -36.46/92

a = - 0.396 m/s²

<h3>Speed of the crate</h3>

v² = u² + 2as

v² = 0.845² + 2(-0.396)(0.65)

v² = 0.199

v = √0.199

v = 0.45 m/s

Thus, the magnitude and direction of the net force on the crate while it is on the rough surface is 36.46 N, opposite as the motion of the crate.

The net work done on the crate while it is on the rough surface is 23.7 J.

The speed of the crate when it reaches the end of the rough surface is 0.45 m/s.

What is sunlight composed of

san4es73 [151]

Answer:

Roughly three quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron. The Sun is a G-type main-sequence star (G2V) based on its spectral class.

You are hiking along a trail in a wide, dry canyon where the outdoor temperature is T = 29.5° C. To determine how far you are aw

STALIN [3.7K]

Answer:

<em>The canyon is approximately 314 meters away</em>

Explanation:

<u>Speed of Sound</u>

If we emit sounds in an open space where a large obstacle (like a mountain) is expected to return the sounds, then it will travel forth and back at a given speed for a certain time. We can assume the speed of sound is constant, so we could know the approximate distance of the mountain (or canyon in our case) by the known formula.
