Answer: The global warming is affecting even the most cold places on earth, where we can find the polar ice caps and the glaciers. These places belong to the arctic glacial ocean.

Explanation: In the pass of time, due the human action on the enviroment, the desappear of the polar ice cover are increasing day after day. We, people, are loosing the prime earth air condicioner sistem, which helps to regulate the climate sistem since the entire history of humanity.

In the year of 2018, researches estimated that the total volume of Arctic sea ice in late summer declined, by two estimates, by 75 percent in half a century.

We must know that the decrease of the arctic sea ice have deep effects on the climactic sistem of earth and, considering the polar ice caps desappearence, the sea temperature will increase a lot, due the reflection of ultraviolet rays on the blue ocean, (not anymore on the white ice), transforming what should be the earth air condicioner sistem to a strong heater.

pentagon [3]

Answer:

No, it is independent

Explanation:

As we know that car is moving horizontally

so the vertical component of the speed is zero initially

so in order to hit the ground we know that

\Delta y = v_y t + \frac{1}{2}at^2

so here we know that

h = 0 + \frac{1}{2}gt^2

on solving above equation for time

t = \sqrt{\frac{2h}{g}}

so we will say that it will not depends on the initial horizontal speed

Ford used to make a 7.0 liter engine. Calculate how many many cubic inches would be the same size engine.
Anestetic [448]

Answer : The volume of engine in cubic inches is, 427.166\text{ inch}^3

Explanation :

As we are given that the volume of engine is, 7.0 liters. Now we have to calculate the volume of engine in cubic inches.

Conversion used :

1\text{ liter}=1000cm^3

So, 7\text{ liter}=7000cm^3

1\text{ inch}=2.54cm

or,

1cm=\frac{1}{2.54}\text{ inch}

1cm^3=(\frac{1}{2.54}\text{ inch})^3

As,

1cm^3=(\frac{1}{2.54}\text{ inch})^3

So,

7000cm^3=\frac{7000cm^3}{1cm^3}\times (\frac{1}{2.54}\text{ inch})^3=427.166\text{ inch}^3

Thu, the volume of engine in cubic inches is, 427.166\text{ inch}^3

A woman sits on a spinning piano stool with her arms extended. When she folds her arms, which of the following occurs? Question
iogann1982 [59]

Answer:

The correct option is that (She decreases her moment of inertia, thereby increasing her angular speed.)

Explanation:

When an object is in circular motion, the vector that describes it is known as angular momentum. Angular momentum is conserved or constant when an object is spinning in a closed system and no external torques are applied to it. An example of conservation of angular momentum is seen when a woman is sitting on a spinning piano stool with her arms extended. Her angular momentum is conserved because the net torque on her is negligibly small as the friction is exerted very close to the pivot point.

When she folds her arms,her rate of spin increases greatly decreasing her moment of inertia. The work she does to pull in her arms results in an increase in rotational kinetic energy( that is, increase in her angular speed). I hope this helps, thanks!

A sound wave with a power of 8.8 × 10–4 W leaves a speaker and passes through section A, which has an area of 5.0 m2. What is th
statuscvo [17]
The intensity of the sound wave is defined as the ratio between the power of the wave and the area through which the wave passes:
I= \frac{P}{A}
where
I is the intensity
P is the power
A is the area

If we use the data of the problem, P=8.8 \cdot 10^{-4}W and A=5.0 m^2, we find the intensity of the sound wave:
I= \frac{P}{A}= \frac{8.8 \cdot 10^{-4} W}{5.0 m^2}=1.76 \cdot 10^{-4} W/m^2
