Two students below described a part of Earth's innermost layer:
Molodets [167]
The answer to your question is B- They both described the inner part otherwise known as the inner core.

The inner core is hotter than the surface of the sun. The inner core is made out of iron and nickel.  The inner core is extremely hot and is the last layer.  It is a solid because of all the pressure from the other layers putting there weight onto this layer.

1) A force of 157 N is applied to a box 25o above the horizontal. If it is applied over a distance of 14.5 m how much work is do
vfiekz [6]

#1

Work done is given by

W = F.d cos\theta

here we know that

F = 157 N

d = 14.5

\theta = 25^0

now from the above formula

W = (157)(14.5)cos25 = 2063.2 J

#2

By energy conservation

Initial total potential energy of egg = final total kinetic energy of egg

mgh = \frac{1}{2}mv^2

v = \sqrt{2gh}

v = \sqrt{2(9.8)(8.2)}

v = 12.7 m/s

#3

By momentum conservation we know that

m_1v_1 = (m_1 + m_2)v

215(9.5) = (215 + 19.7) v

v = \frac{215 (9.5)}{215 + 19.7}

v = 8.7 m/s

#4

by momentum conservation we know that

m_1v_1 + m_2v_2 = (m_1 + m_2) v

let direction of velocity of Jay Z car motion is positive direction

now we will say

1100(-20) + 1475v = (1100 + 1475)(7)

1475 v = 2575(7) + 1100(20)

v = 27.14 m/s

Yes Jay Z is overspeeding as his speed is more than speed limit

#5

Tension force in the string will be centripetal force

so here we can say

T = \frac{mv^2}{R}

here we know that

m = 0.63 kg

v = 7.8 m/s

R = 0.23 m

T = \frac{0.63 (7.8)^2}{0.23}

T = 166.6 N
