Explanation:
Given
---- Altitude of container in Denver
-- Surface Area of the container lid
--- Air pressure in Denver
--- Air pressure in New Orleans
<em>See comment for complete question</em>
Solving (a): The expression for
Force is calculated as:
The force in New Orleans is:
Since the inside pressure is half the pressure at sea level, then:
Where
--- Standard Pressure
Recall that:
This gives:
Solving (b): The value of
In (a), we have:
Where
So, we have:
Answer: 9.8N
Explanation: The velocity of a sound wave (v), tension on the string (T) and mass per unit length (u) are all related by the formulae below
T = v² * u
Where T is tension in Newton (N), v is velocity of sound waves in meter per seconds (m/s) and u is mass per unit length in kilogram per meter (kg/m)
u = mass of chord / length of chord
u = 0.44/ 8.1
u = 0.1 kg/m
Velocity of sound waves (v) =length of chord / time taken for wave to travel
v = 8.1 / 0.82 = 9.9m/s
Tension is calculated below using the formula
T = v² * u
T = (9.9)² x 0.1
T= 9.8N
Do it in order of the steps, then the ones that are not in the process do the definition and draw a picture. For the steps also draw pictures!
Answer:
Option A is correct.
Explanation:
In the given triangle , x is the base and 14 is the hypotenuse for angle 33°.
cos 33 = base / hypotenuse
Putting the given values
cos 33 = x / 14
.84 = x / 14
x = .84 x 14
= 11.7
Option A is correct.
