Answer:

The resultant vector is \vec R = \vec A + \vec B = 7.196\,i + 6.464\,j.

Explanation:

First, each vector is determined in terms of absolute coordinates:

6-meter vector with direction: 30º north of east.

\vec A = (6\,m)\cdot (\cos30^{\circ} \,i + \sin 30^{\circ}\,j)

\vec A = 5.196\,i + 3\,j

4-meter vector with direction: 30º east of north.

\vec B = (4\,m)\cdot (\cos 60^{\circ}\,i + \sin 60^{\circ}\,j)

\vec B = 2\,i + 3.464\,j

The resultant vector is obtaining by sum of components:

\vec R = \vec A + \vec B = 7.196\,i + 6.464\,j

The resultant vector is \vec R = \vec A + \vec B = 7.196\,i + 6.464\,j.

Climate and weather are related but different. Which of the following describes the climate of a place?
iren2701 [21]

Climate. What does it mean?

<em>Climate is a long-term weather, or recurring every time. Examples of climate? </em><u><em>Every day, the desert is hot the day and cold in the night.</em></u><em> This won't change, at least for hundreds, thousands, millions of years. This is climate.</em>

Weather. What does it mean?

<em>Weather is short-term, usually not recurring every time. Examples of weather? </em><u><em>Today is very sunny.</em></u><em> This will change-for all we know, tomorrow will be cloudy and rainy!</em>

<em />

This is why your answer will <u>NOT</u> be a meteorologist predicts that tomorrow will be sunny and warm. This is weather, because it is only <em>tomorrow.</em>

<em />

This is why your answer will <u>NOT</u> be fertile soil makes farms in the region very productive. This does not relate to weather, or climate.

This is why your answer will <u>NOT</u> be the temperature dropped below freezing every night last week. This will only be "last week", not the week right now or the week after this week.

<em><u>Therefore, your answer is "Thunderstorms frequently occur in the summer. </u></em>This is because that's the climate in that part- thunderstorms always happen.

1. When does raising the temperature of a gas increase its pressure? when volume is increased and the number of particles is con
Neporo4naja [7]

Answer:

when volume and the number of particles are constant

Explanation:

Gay Lussac law states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Gay Lussac's law is given by;

PT = K

\frac{P1}{T1} = \frac{P_{2}}{T_{2}}

The ideal gas law is the equation PV = nRT

Where;

P is the pressure.

V is the volume.

n is the number of moles of substance.

R is the ideal gas constant.

T is the temperature.

Generally, raising the temperature of an ideal gas would increase its pressure when volume and the number of particles are constant.

This ultimately implies that, when volume and the number of particles are held constant, there would be a linear relationship between the temperature and pressure of a gas i.e temperature would be directly proportional to the pressure of the gas. Thus, an increase in the temperature of the gas would cause an increase in the pressure of the gas at constant volume and number of particles.
