it is generated by two objects pushing against each other with equal/almost equal force, therefore contracting against each other
The type of conversion that is taking place when natural gas is
burned to heat water is referred to as chemical conversion. In this
conversion thermal energy is produced.
Answer:
Explanation:
mass of the astronaut including the spacesuit, 
distance of astronaut from the spaceship, d = 13 m
mass of the oxygen tank, m = 3 kg
Speed of tank with respect to spaceship, 
a)
<u>Using the conservation of linear momentum:</u>
total momentum before collision = total momentum after collision



b)
She mush hold her breath until she reaches the spaceship, i.e.



Answer:
if one bulb burns out the other will also turn off because they are connected to each other.
Answer:
t = 1.10 h
Explanation:
For this exercise we must calculate the intensity that reaches the cell with the polarizers, for this we use Malus's law
I = I₀ cos² θ
Let's calculate
I = I₀ cos² 60
I = I₀ 0.907
This is the intensity that reaches the cell
To find time, use an inverse proportion rule or rule of three, the intensity Io in
t = I₀ / (0.907 I₀) 1 h
t = 1.10 h
