Difference between universal law of gravitation and acceleration due to gravity​

Physics
1 answer:
marishachu [46]3 years ago
7 0

Explanation:

The acceleration on an object due to the gravity of any massive body is represented by g (small g). The force of attraction between any two unit masses separated by unit distance is called universal gravitational constant denoted by G(capital g). The relation between G and g is not proportional. That means they are independent entities.

G and g

In physics, G and g can be related mathematically as –

\(g=\frac{GM}{R^{2}}\)

Where,

1=g is the acceleration due to the gravity of any massive body measured in m/s2.

2=G is the universal gravitational constant measured in Nm2/kg2.

3=R is the radius of the massive body measured in km.

4=M is the mass of the massive body measured in Kg.

Explanation:

(a)

Considering the short transition line diagram.

Apply kirchoff's voltage law to the short transmission line.

Write the equation showing the relations between the sending end and the receiving end quantities.

Compare the line equations with the A,B,C,D parameter equations.

(b)

Determine the receiving-end current for 0.9 lagging power factor.

Determine the line-to-neutral receiving end voltage.

Determine the sending end voltage of the short transition line.

Determine the line-to-line sending end voltage which is the sending end voltage.

nalin [4]

Answer:

Atlanta is at 596.0 km from the house.

Explanation:

The distance between Atlanta and the house can be found using the following equation:

v = \frac{d}{t}   (1)

Where:

v: is the speed = 80 km/h

t: is the time = 7.45 h

By solving equation (1) for d and entering the above values we have:

d = v*t = 80 km/h*7.45 h = 596.0 km = 596000 m

Therefore, Atlanta is at 596.0 km from the house.

I hope it helps you!

Akia is balancing the equation Na + H2O NaOH + H2. He tries to find the coefficients that will balance the equation.
Pepsi [2]
<h3><u>Answer;</u></h3>

A: by counting up each individual atom and make sure the atom numbers are the same in the reactants and the products

<h3><u>Explanation;</u></h3>
  • <em><u>According to the law of conservation of mass, the mass of reactants should always be the same as the mass of the products in a chemical equation. </u></em>Therefore, <em><u>the number of atoms of each element in a chemical equation should always be the same on both sides of the equation, </u></em>that is the side of reactants and side of products.
  • Thus, <em><u>any chemical equation requires balancing to ensure that the number of atoms of each element is equal in both sides of the equation</u></em>. Balancing is a try and error process that ensures that the law of conservation of mass holds.
  • In this case, the balanced equation would be;                                               2Na +2H₂O → 2NaOH +H₂
