<span> For this case, the first thing we are going to do is define variables:
x: size of the radius of the star
Y: size of the solar radio.
Let's write an equation that models the problem:
a star has a size of 0.1 solar radius:
</span>

<span> Clearing y we have:
</span>

<span> Rewriting we have:

Answer: the sun is 10 times larger than this star</span>
Answer:
28.7m
Explanation:
Given parameters;
Work done = 430J
Force applied = 15N
Unknown:
Distance moved = ?
Solution:
Work done is the force applied to move a body through a certain distance.
Work done = Force x distance
So;
430 = 15 x distance
Distance = 28.7m
Answer:
A spring is compressed and held at compression by a person before releasing it
Explanation:
All the other answers are showing things that are at rest and have no energy starting nor going through them. This answer show how the energy is starting and being released.
Answer: The correct answer is option (A).
Explanation:
Momentum of the car with 0.04 kg mass , which travelling with velocity of 2.00 m/s

Then the maximum speed of the another car in order to not to break the eggs will be same as first car:



Speed slightly more than 1 m/s will increase the momentum of second car and the eggs will break. So, from the given options the minimum speed need by the second car will be 1.42m/s.
Answer:
The correct answer is "0.32 mL".
Explanation:
The given values are:
Density of gold bar,
d = 19.3 g/mL
Mass of gold bar,
m = 6.3 grams
Now,
The volume will be:
⇒ 
or,
⇒ 
On substituting the values, we get
⇒ 
⇒
