Answer:
C) Pnew=Poriginal/9
Explanation:
From the given conditions:
Original area, 
New area of the barrel bottom panel after increasing by a factor of 3:

On increasing the radius the area now becomes:


As we know that there will be no increase in the down-force since the height remains constant.
Pressure is given as:

∴New pressure:


Answer:
A 1.56 see below
Explanation:
I will assume the 45 degree force is upward
vertical component = 600 sin 45 = 424.26 N
added to the other vertical force will total 824.26 N
F = ma
824.26 = 100 * a shows a = 8.24 m/s upward
Now we have to assume the mass is ALSO acted on by gravity and this value is given as 9.8 ( so downward is positive)
9.81 - 8.24 = 1.56 m/s^2
Answer:
Burning match represents exothermic reaction.
Explanation:
Exothermic reaction:These are the reaction which releases energy into the surroundings.
Endothermic reaction:These are the reaction which absorbs energy from the surroundings.
Burning of the match stick is an Exothermic reaction.This is because amount of energy required to burn the match is very less than of the energy given out by the match on burning.
Input Energy < Output Energy
