Which of the following natural disasters are meteorologists able to predict?

Gelneren [198K]

Answer:

Hey, how you doing.

I think (warning I said think not to know!) that it is A because of the following:

Eruptions can be predicted if you have a good history of their activity. you also need to have lots of equipment constantly monitoring. Tsunamis can't really be predicted because earthquakes can't (that's why B is wrong). But however, if there is a giant asteroid impact you can predict that it will cuase i giant tsunamis.

A is the only one with 1 correct answer so I would go with it.

A voltmeter has an internal resistance of 10 000 Ω and is used to measure the voltage across a 47.0-Ω resistor that, without the

otez555 [7]

Answer:

b. 5.6 mA

Explanation:

As the voltmeter is connected to the resistor in parallel. The new resistance of the systems is

$\frac{1}{R} = \frac{1}{r_1} + \frac{1}{r_2} = \frac{1}{10000} + \frac{1}{47} = 0.0214$

R = 1/0.0214 = 46.78 Ω

The voltage is

$U = r_2 I_1 = 47 * 1.2 = 56.4 V$

So the new current now of the system is

$I_2 = U/R = 56.4/46.78 = 1.2056 A$

So about 1.2056 - 1.2 = 0.0056 A or 5.6mA is drawn away.

What is the acceleration of a softball if it hits the ground with a force 0.50 kg and hits the catchers glove with a force of 25

Rom4ik [11]

Acceleration of the ball is $50 m/s^2$

Explanation:

The acceleration of the ball can be found by using Newton's second law of motion, which states that the net force acting on an object is equal to the product between the mass of the object and its acceleration:

$F=ma$

where

F is the net force

m is the mass

a is the acceleration

For the ball in this problem, we have

m = 0.50 kg (mass)

F = 25 N (force)

thereofre, the acceleration of the ball is

$a=\frac{F}{m}=\frac{25}{0.50}=50 m/s^2$

What is the overall effect of Earth's global atmospheric circulation?

yulyashka [42]

Atmospheric Circulation is the large-scale movement of air by which heat is distributed on the surface of Earth.
The wind belts and the jet streams girdling the planet are steered by three convection cells: the Hadley cell, the Ferrel cell, and the Polar cell.
While the Hadley, Ferrel, Polar cells are major players in global heat transport, they do not act alone.
Disparities in temperature also drive a set of longitudinal circulation cells, and the overall atmospheric motion is known as the zonal overturning circulation.
