Answer:
The <u>Force of Gravity</u> force between each planet and the Sun keeps the planets in orbit around the Sun.
Explanation:
A measured value is expressed as a number along with a corresponding unit. The unit represents the dimension of the measured value.
For example:
- Length of an object can be expressed as, value + dimension. for example 10 m where 'm' is the dimension of length; meters
- Volume can be expressed as, value + dimension, for example, 10 L where L is the dimension of volume; Liters.
Ans C) Dimension
Answer: The Answer is C.
Explanation: The Nucleus only makes up less than .01% of the volume of the Atom. The Nucleus does contain more than 99.9% of the mass of the Atom. I hope that this helps you! Good luck!
Answer:
The new pressure is 3850 torr.
Explanation:
The relation between volume and pressure is inverse as per Boyle's law. Its mathematical form is given by :

Here,



Let
is the new pressure. So using Boyle's law we get :

or

So, the new pressure is 3850 torr.
Answer:
Thus the order of covalent character will be
DG < EG < DF < DE
Explanation:
The electronegativity decides the nature of bond formed between two atoms.
More the difference in electronegativity more the ionic character in the bond formed.
Let us check the electronegativity difference between the elements forming molecules
a) DE :
3.8-3.3 = 0.5
b) DG :
3.8-1.3 = 2.5
c) EG
3.3-1.3 = 2
d) DF
3.8-2.8 = 1.3
So the maximum ionic character will be in DG and minimum in DE
Thus the order of covalent character will be
DG < EG < DF < DE
