Answer:

$N=14854.5turns$

Explanation:

Given data

Length L=0.24 m

Magnetic field B=7.0 T

Current I=90 A

To find

Number of turns N

Solution

As we know that magnetic field is given as:

$B=u_{o}I\frac{N}{L}$

Rearrange the equation and solve for N

$B=u_{o}I\frac{N}{L}\\\frac{B}{u_{o}I} =\frac{N}{L} \\N=\frac{LB}{u_{o}I}\\N=\frac{(0.24m)(7.0T)}{4\pi *10^{-7}*(90A)} \\N=14854.5turns$

Vehicle crumple zones are designed to absorb energy during an impact by deforming to reduce energy transfer to the occupants. Ho

rusak2 [61]

Answer:

change in KE = -12.95 Btu

Explanation:

given data

mass = 3000-lbm

velocity of vehicle initial vi = 10 mph = 14ft/s

velocity of vehicle final vf = 0 mph = 0 ft/s

solution

as here for crumple zone to protected zone it will absorb kinetic energy

so change in KE is related here initial and final velocity that is

change in KE = 0.5 × m × (vf² - vi² ) .................1

put here value and we get

change in KE = 0.5 × 3000 × (0² - 14.7² )

change in KE = -324135 × $\frac{1lbf}{32.174\ lb.ft/s^2}$ * $\frac{1Btu}{778.17 ft.lbf}$

change in KE = -12.95 Btu

NASA launches a satellite into orbit at a height above the surface of the Earth equal to the Earth's mean radius. The mass of th

Rzqust [24]

Answer:

a) 3h 59’ b) 5,590 m/s c) 1,910 N

Explanation:

The only force acting on the satellite (neglecting the influence of any other body) is just the attractive force from Earth, which is given by the Universal Law of Gravitation:

Fg = G* ms*me / (res² (1)

where: G = 6.67* 10⁻¹¹ N.m² / kg² ms = 780 kg, me= 5.97* 10²⁴ kg, and

res = 2* 6.38* 10⁶ m (distance between the center of the Earth and the satellite).

Fg = 1,910 N (answer c)

At the same time, this force, is the centripetal force that keeps the satellite in orbit, and that can be written as follows:

Fg = ms * v² / res (2)

By definition of velocity, we can say that the constant speed at which the satellite orbits, can be expressed as the quotient between the distance travelled around the Earth once, and the time needed to do that, which is called the period of the orbit:

v = 2*π*res / T (3)

We can solve for v first, taking the right sides of (1) and (2), as follows:

G* ms*me / (res)²= ms * v² / res

v = √(G*me/r) = 5,590 m/s (answer b)

Once obtained the value of v, we can replace in (3), and solve for T:

T = 2* π*res / v = 3 h 59 min (answer a)

1. Describe the differences in the ways the sand castle is changed by an ocean wave and by Dylan stomping on it

Snezhnost [94]

A sand castle that was changed by the ocean waves would be slowly taken away from by the waves and would just become a smooth mound of sand. If Dylan stomped on it then it would still have all of the same sand as before but in a different shape. It would also become a mound of sand but it would have all the same sand as before.

(I don't know if I was supposed to talk about fancy physics stuff so I just gave a basic explanation. I don't know if my answer is really right or not... hope it helped though :))
