Answer:
Because the bullet is smaller and has a sharp/pointy tip.
Explanation:
The bullet kinda puts the majority of kinetic energy in a small are, whereas the gun butt kinda spreads the energy evenly amongst a larger surface. If more explanation is needed add comment.
Answer: The volume of the diver's at the same depth, at a temperature of 21.0°C and a pressure of 141.20 kPa is 1.66 L
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 101.30 kPa
= final pressure of gas = 141.20 kPa
= initial volume of gas = 2.40 L
= final volume of gas = ?
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
The volume of the diver's at the same depth, at a temperature of 21.0°C and a pressure of 141.20 kPa is 1.66 L
<span>A plane flies along a straight line path after taking off, and it ends up 210 km farther east and 90.0 km farther north, relative to where it started. we should use Pythagoras theorem for this.
distance^2= 210^2 + 90^2.=228.47km, when rounding off this would comes around 230 km</span>
