Answer: 2.878 parsecs
Explanation:
To convert astronomical units (AU) to parsecs (pc), you can use the following relationship:
1 parsec (pc) = 206,265 AU
Now, you can simply divide 594,000 AU by this conversion factor:
594,000 AU / 206,265 AU/pc ≈ 2.878 parsecs
So, there are approximately 2.878 parsecs in 594,000 astronomical units.
Answer:
a = 2 m/s²
Explanation:
Given: 20 g, 40N
To find: Acceleration (a)
Solution: To find the acceleration (A), divide the force by the weight
A = F ÷ m
= 40 ÷ 20
= 2 m/s²
Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.
B. compounds
C. Molecules
D. atoms
Molecules collide and create a movement of heat called conduction.
Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules ,
When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:
1) heat conduction
2) electrical conduction
3)sound conduction

Answer:
c.
Explanation:
Answer:
diameter ≅ 3 inches
Explanation:
Use a constant factor, k
Let Hp = horsepower
Let s = speed in rpm
Let d = diameter in inches
to find constant k, using
Hp=46
S=100
d=3 in
To find diameter when;
Hp=74
S=175
k=0.017
d=d inches
d≅ 3 inches
Importanceofozonelayer:
Explanation:
Formationofozonelayer:ozone at the higher level of the atmosphere is a product of UV radiations acting on oxygen O2 molecule. The higher energy UV radiations split apart some molecular oxygen( O2) into free oxygen (O) atoms.
Depletionodozonelayer:The amount of ozone in the atmosphere began to drop sharply in the 1980's . This decrease has been linked to synthetic chemicals like cholorofluorocarbons ( CFC's ) which are used as refrigerants and in fire extinguishers.
