1) low pressure systems tend to result in unsettled weather and may present clouds high winds and precipitation. As low pressure intensifies storms or hurricane may be formed

1. because the air continues to cool and the water vapor may condense into precipitation, which results in unsettled weather

2. air is more dense in a region of high pressure, so the air pushes toward less dense regions. the air begins to warm as it descends, gets rid of the formation of clouds

Answer:

C. It decreases by a factor of 4

Explanation:

F1 = kq1*q2/r²

F2 = kq1*q2/(2r)² = kq1*q2/(4r²) = kq1*q2/(r²*4) = F1/4

When you graph an inequality you used a closed dot or a open dot

Naddik [55]

For ≤ and ≥ , use a closed dot to indicate the number itself is part of the solution. For < and >, use an open circle to indicate the number itself is not part of the solution.

H2(g) + Co(g) _CH3OH<br> balance the equation <br>

Tom [10]

Answer:

CO + 2H2 = CH3OH

Explanation:

1. Label Each Compound With a Variable

aCO + bH2 = cCH3OH

2. Create a System of Equations, One Per Element

C: 1a + 0b = 1c

O: 1a + 0b = 1c

H: 0a + 2b = 4c

3. Solve For All Variables (using substitution, gauss elimination, or a calculator)

a = 1

b = 2

c = 1

4. Substitute Coefficients and Verify Result

CO + 2H2 = CH3OH

which two quantities are used to predict gravitational force according to Newton's law of universal gravitation a. mass and spee

NISA [10]

Answer:

(b). Mass and distance.

Explanation:

The gravitational force between two objects is given by Newton's law of universal gravitation. The formula is as follows :

$F=G\dfrac{m_1m_2}{r^2}$

Here,

G is universal gravitational constant

r is the distance between two objects

It is very clear that the gravitational force is directly proportional to the product of masses and inversely proportional to the square of the distance between them.

Hence, the two quantities are used to predict gravitational force according to Newton's law of universal gravitation are mass and distance.
