Answer:
Coriolis Effect
Explanation:
The Coriolis effect is responsible for the deflection of winds to the right in the Northern hemisphere and to the right in the Southern hemisphere. It is an effect that occurs because of the rotation of the earth around its axis.
The implication of this is that in areas of low pressure in the Northern hemisphere, winds tend to blow in anticlockwise direction, and in areas of high pressure, it blows in a clockwise direction. The opposite of this happens in the Southern hemisphere.
The answer is 4.0 kg since the flywheel comes to rest the
kinetic energy of the wheel in motion is spent doing the work. Using the
formula KE = (1/2) I w².
Given the following:
I = the moment of inertia about the
axis passing through the center of the wheel; w = angular velocity ; for the
solid disk as I = mr² / 2 so KE = (1/4) mr²w². Now initially, the wheel is spinning
at 500 rpm so w = 500 * (2*pi / 60) rad / sec = 52.36 rad / sec.
The radius = 1.2 m and KE = 3900 J
3900 J = (1/4) m (1.2)² (52.36)²
m = 3900 J / (0.25) (1.2)² (52.36)²
m = 3.95151 ≈ 4.00 kg
To my knowledge, it would be the day.
<em><u>one year: earth </u></em><em><u>revolves around the sun</u></em>
<em><u> one</u></em><em><u> month: moon revolution around the earth</u></em>
<em><u>one</u></em><em><u> day: the earth rotation about its axis</u></em>
However, nothing above indicates what day of the week it is; you can tell when a day has passed, but not what day of the week is.
Hope this helps!

To solve this problem it is necessary to apply the concepts related to energy conservation. Therefore, the work done will initially be equivalent to the change in kinematic energy. And this kinematic energy will be equivalent to the sum of energy (work) carried out by force and friction. In this way we have to
Now,
For each one we have
Then at the equation of equilibrium of energy we have,
Therefore the work done by friction on the chair is -833.7J
The correct answer for this would be the third option. Antibiotic medicine. The one that is used to treat a bacterial infection is an antibiotic medicine. Antibiotics inhibit the growth of or destroys microorganisms. Examples of medicine include Penicillin or its derivatives. Hope this answers your question. Have a great day!<span>
