Answer:

Explanation:
give,
Gauge pressure of car, P₁ = 30 psi
temperature,T₁ = 0° C = 0 + 273 = 273 K
Assuming temperature at the noon = 30° C
T₂ = 30 + 273 = 303 K
Pressure at this temperature, P₂ = ?
Using ideal gas equation

taking volume as in compressible V₁ = V₂




Hence, Pressure of the at 30°C is equal to 33.297 psi.

Answer:
DU = 21 KJ
Explanation:
Given the following data;
Quantity of heat = 125 KJ
Work = 104 KJ
To find the change in internal energy;
Mathematically, the change in internal energy of a system is given by the formula;
DU = Q - W
Where;
DU is the change in internal energy.
Q is the quantity of energy.
W is the work done.
Substituting into the formula, we have;
DU = 125 - 104
DU = 21 KJ
Answer:
Vertical Height = 0.784 meter, Speed back at starting point = 10 m/s
Explanation:
Given Data:
V is the overall velocity vector,
and
are its initial vertical and horizontal components

To find:
Max Height
achieved
Calculation:
1) Using the
equation of motion, we know

2) In terms of gravity
height
and the vertical component of Velocity
.
3) As
as at maximum height the vertical component of velocity is zero maximum height achieved

putting values
4) 
5) As for the speed when it reaches back its starting point, it will have a speed similar to its launching speed, the reason being the absence of air friction (Air drag)
