Answer:

Explanation:
As we know that
PV = nRT
here we have


so we have

T = 290 K
now we have


now the mass of gas is given as



now density of gas when its volume is increased to 3.3 L
so we will have



It's too much I don't understand.sorry
The answer is d hope this helps
Answer:
The angle is 65.6°.
Explanation:
Given that,
Speed = 2.20 m/s
Distance from the shore= 500 m
Distance from the bottom= 1100 m
Speed of boat = 7.30 m/s
According to figure,
We need to calculate the angle with shore
Using formula of angle

Put the value into the formula



We need to calculate the angle

Put the value into the formula


Hence, The angle is 65.6°.
