How does the see temperature affect hurricane formation?

insens350 [35]

The higher the sea surface temperature, the faster the warm, moist air rises into the atmosphere. This updraft creates a donut shaped vortex that is rising in the middle and going downward on the sides. The more moisture in the air (humidity), the stronger the vortex will become as the moisture rises through convective currents, cools, and falls through convective currents. This eventually causes rotation of the storm mass and you get a tropical cyclone. So, the high sea surface temperatures and humidity are actually the engine that forms a hurricane and causes it to increase in strength.

High level horizontal winds can prevent a hurricane from forming. These are called shear winds and they literally blow the top of the cyclone off, preventing it from forming properly.

Use differentials to estimate the amount of tin in a closed tin can with diameter 3 inch and height 4 inch, if the top and botto

Aloiza [94]

Answer:

dv = 1.03 inch^3

Explanation:

given data:

diameter = 3 inch

radius = 1.5 inch

height 4 inch

top and bottom thickness is 0.02 inch

side thickness = 0.015 inch

we know that volume of the cylinder is given as

$v =\pi r^2 h$

by definition of differential we have

$dv =\frac{\partial v}{\partial r} dr + \frac{\partial v}{\partial h} dh$

where dh = -(0.02 + 0.02) = 0.04 inch [ sum of top and bottom thickness]

the radius is decreased by 0.02 inch, dr = 0.02 inc,

$\frac{\partial v}{\partial r} = 2\pi r h = 37.69$

$\frac{\partial v}{\partial h} = \pi r^2 = 7.06$

dv = 37.69*(0.02) + 7.06*(0.04)

dv = 1.03 inch^3

You place a box weighing 253.1 N on an inclined plane that makes a 39.7◦ angle with the horizontal.

Masja [62]

Answer:

Explanation:

The weight of the box is

W = 253.1N

Weight is on an incline plane

θ = 39.7°

The weight of an object is always acting downward

So, the weight makes an angle of 39.7° with the vertical component

Then, it's horizontal component is

Wx = W•Sinθ

Wx = 253.1 × Sin 39.7°

Wx = 161.67 N

The horizontal component of the weight is 161.67N

This is the force acting down the plane.
