Answer:
Final volumen first process
Final Pressure second process
Explanation:
Using the Ideal Gases Law yoy have for pressure:
where:
P is the pressure, in Pa
n is the nuber of moles of gas
R is the universal gas constant: 8,314 J/mol K
T is the temperature in Kelvin
V is the volumen in cubic meters
Given that the amount of material is constant in the process:
In an isobaric process the pressure is constant so:
Replacing :
Replacing on the ideal gases formula the pressure at this piont is:
For Temperature the ideal gases formula is:
For the second process you have that So:
Answer:
a) There are 100 centimeters in 1 meter.
b)
Explanation:
a) We have the conversion
1 m = 100 cm
So there are 100 centimeters in 1 meter.
b) 1 inch = 2.54 cm
It depends on both of them.
In fact, the projectile begins its motion with an initial velocity of
and an angle of 
. On the y-axis (vertical direction), it is an accelerated motion with acceleration equal to -g (gravitational acceleration). The vertical velocity of the projectile at any time t is given by
and as it can be seen, this depends on both initial velocity and angle.
