The first four planets in our solar system are rocky. How does that relate to Newton’s law of universal gravitation?
Serhud [2]

Explanation:

According to Newton law of gravity, the strength of gravitational pull between two objects is related to their masses, directly, and inversely by the distance between them;

F = G * (M₂ – M₁) / d where;

F – the force of gravity

G – gravitational constant

M₂ – the mass of one object

M₁ – the mass of the other object

d – the distance between the two objects

The rocky planets have a higher mass than the gas planets hence will be strongly ‘feel’ the gravitational pull of the star in the solar system revolves about.  This is why rocky planets are closer to their star while gas planets are towards the outer edges.

CaCl2<br> Ca +<br> CI2<br> Balance this equation
Elis [28]

To balance Ca + Cl2 = CaCl2 you'll need to be sure to count all of atoms on each side of the chemical equation.

Once you know how many of each type of atom you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation for Calcium + Chlorine gas.

Calculate the final temperature of the system: A 50.0 gram sample of water initially at 100 °C and a 100 gram sample initially a
katrin2010 [14]

Answer:

The final temperature of the system is 42.46°C.

Explanation:

In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.

q_1=-q_2

m_1\times c\times (T_f-T_1)=-(m_2\times c\times (T_f-T_2))

where,

c = specific heat of water= 4.18J/g^oC

m_1 = mass of water sample with 100 °C= 50.0 g

m_2 = mass of water sample with 13.7 °C= 100.0 g

T_f = final temperature of system

T_1 = initial temperature of 50 g of water sample= 100^oC

T_2 = initial temperature of 100 g of water =13.7^oC

Now put all the given values in the given formula, we get

50.0 g\times 4.184 J/g^oC\times (T_f-100^oC)=-(100 g\times 4.184 J/g^oC\times (T_f-13.7^oC))

T_f=42.46^oC

The final temperature of the system is 42.46°C.
