Explanation:

Given formula:

ME= $\frac{1}{2}$ mv²+mgh

To make height the subject of the formula, follow the following procedures;

Subtract $\frac{1}{2}$ mv² from both side of equation

M.E - $\frac{1}{2}$ mv² = $\frac{1}{2}$ mv² - $\frac{1}{2}$ mv²+mgh

This gives:

M.E - $\frac{1}{2}$ mv² = mgh

Multiply both sides of the expression by $\frac{1}{mg}$

( M.E - $\frac{1}{2}$ mv² ) x $\frac{1}{mg}$ = $\frac{1}{mg}$ x mgh

h = ( M.E - $\frac{1}{2}$ mv² ) x $\frac{1}{mg}$

Describe how the coriolis effect acts differently based on location on earth

sammy [17]

Explanation:

The Coriolis effect happens when an entity is perceived from a moving reference frame going in a straight path. The changing reference frame makes the object appear as if it were moving along a curved road.

Circulation is counter-clockwise in the northern hemisphere. Circulation is clockwise in the southern hemisphere, and it is the equator, it is straight down without circulation.

A handful of professional skaters have taken a skateboard through an inverted loop in a full pipe. For a typical pipe with a dia

Bingel [31]

Answer

given,

diameter of the pipe is = (14 ft)4.27 m

minimum speed of the skater must have at very top = ?

At the topmost point of the pipe the normal force will be equal to zero.

F = mg

centripetal force acting on the skateboard

$F = \dfrac{mv^2}{r}$

equating both the force equation

$mg = \dfrac{mv^2}{r}$

$v = \sqrt{gr}$

r = d/2 = 14/ 2 = 7 ft

r = 4.27/2 = 2.135 m

g = 32 ft/s² or g = 9.8 m/s²

$v = \sqrt{32 \times 7}$

v = 14.96 ft/s

$v = \sqrt{9.8 \times 2.135}$

v = 4.57 m/s

The Gulf Stream is an ocean current that runs from the southern tip of Florida up the eastern coast of the U.S. And ends in the

dmitriy555 [2]

Answer:

The Northern flowing stream will affect the coast of Europe by making climate of Western Europe and Northern Europe to be warmer than other areas that are located around the same latitude and this is simply because of the North Atlantic Current

Explanation:

The Northern flowing stream will affect the coast of Europe because the North Atlantic current causes the Gulf stream to be split into two ( 2 ) and the Northern stream which is a warm stream crossing over to Northern Europe. <em>The Gulf stream makes climate of Western Europe and Northern Europe to be warmer than other areas that are located around the same latitude and this is simply because of the North Atlantic Current</em>

A train is travelong at 22 m/s when the condutor gets a radio call about a car stalled on the tracks. He hits the emergancy brak

mylen [45]

Answer:

final velocity = 0

because the train stoped

so,

acceleration = (v - u) ÷ t
acceleration = (0 - 22) ÷ 135
acceleration = -22 ÷ 135

acceleration = -0.162 m/s²
