Which is the best estimated pressure, represented in units of GPa, of the lower mantle?
IrinaVladis [17]

Answer : The best pressure is 110 GPa of the lower mantle.

Explanation : We know that the pressure in the lower mantle starts at 24 GPa and reach a 136 GPa at the boundary.

So, the best pressure is 110 GPa because 220 GPa, a 305 GPa and 360 GPa are the higher value of  the maximum value 136 GPa of the lower mantle.

Use the exact values you enter to make later calculations. Jack and Jill are on two different floors of their high rise office b
erastovalidia [21]

The part B of the question is missing and it is;

b) What is the height between the two window ledges?

Answer:

A) 20.76 m/s

B) 161.52 m

Explanation:

A) To calculate the initial speed we use the formula from Newton's first law of motion:

v = u + at

Making u the subject gives;

u = v - at

Where;

v is the final velocity which is the speed when Jill sees the pot = 60 m/s

u is the initial velocity which is the speed when Jack sees the pot go by

t is the time between the two observed events = 4 s

a in this question is acceleration due to gravity = 9.81 m/s².

Plugging in the relevant values into the initial velocity equation gives;

u = 60 - (9.81 × 4)

u = 20.76 m/s

B) To get the height difference, we will use the formula;

(y1 - y0) = ut + ½at²

Thus, plugging in the relevant values, we have;

y1 - y0 = (20.76 × 4) + (½ × 9.81 × 4²)

(y1 - y0) = 161.52 m
