Answer: C. 1000 Newton
Explanation:
Given that :
Weight of moon rover on earth = 6000 newton
Approximate of moon rover on moon will be?
Weight of an object (W) = mass(m) × acceleration due to gravity(g)
To get the mass of moon rover(m) :
m = weight / acceleration due to gravity
g on earth = 9.8m/s²
Hence,
mass of moon rover = 6000/ 9.8
= 612.244kg
Surface gravity on the moon is about 1.6m/s²
Hence ;
Weight of moon rover on the moon :
Mass of moon rover × 1.6m/s²
= 612.244 × 1.6m/s²
= 979.59 Newton
= 1000 Newton (nearest thousand)
Answer:- 3.84 grams
Solution:- Volume of the sample is 44.8 mL and the density is 1.03 gram per mL.
From the density and volume we calculate the mass as:
mass = volume*density
= 46.1 g
From given info, potassium bromide solution is 8.34% potassium bromide by mass. It means if we have 100 grams of the solution then 8.34 grams of potassium bromide is present in. We need to calculate how many grams of potassium bromide are present in 46.1 grams of the solution.
The calculations could easily be done using dimensional analysis as:
= 3.84 g KBr
Hence, 3.84 grams of KBr are present in 44.8 mL of the solution.
The electron configuration that belongs to the atom with the lowest first ionization energy is francium.
<h3>What is ionization energy? </h3>
Ionization energy is defined as the minimum amount of energy required to remove the most loosely electron present in outermost shell.
<h3>Ionization energy across period</h3>
Ionization energy increase as we move from left to right in the period. This can be explained as when we move from left to right along period new electron is added to the same shell which increase the nuclear charge. Hence results int he decrease in size. Due to this decrease in size more energy is required to remove electron from outermost shell.
<h3>Ionization energy along group</h3>
Ionization energy decrease as we move from top to bottom along group. This can be explained as we move from top to bottom new electron is added to new shell. Due to addition of new shell the size of atom increases which results in the decrease in the nuclear charge. Due to this less amount of energy is needed to remove an electron.
Thus, we concluded that the electron configuration that belongs to the atom with the lowest first ionization energy is francium.

Answer:
The correct answer is "increase; faster".
Explanation:
The kinetic energy is defined as the power that an object has result of its movement. The kinetic energy of a substance has a direct relation with the temperature. As the temperature rises, the kinetic energy of the molecules increases, result of an increase in the speed of its movement. A higher temperature causes that the particles vibrate faster, which increases the kinetic energy.
