Answer:
The pressure corresponding to the absolute zero temperature is 0.997atm.
Explanation:
To solve this question, you draw a straight vertical line with the boiling point temperature and pressure on top of the line and the freezing point temperature and pressure on the lower part. The absolute temperature somewhere in the middle of the line with the pressure to be obtained.
So, we have;
0- (-19) / 100 - (-19) = P - 0.9267 / 1.366 - 0.9267
19 / 119 = P - 0.9267 / 0.4393
Cross multiply, we have
19 * 0.4393 = 119(P -0.9267)
8.3467 = 119P - 110.2773
119P = 118.624
P = 0.997 atm
So at 0°C, the pressure of the thermometer is 0.997atm.
Answer:
We will go in the same direction where the car was was moving before applying brakes
Our speed will be same as that of speed of the car before applying brakes i.e. 30 mph
This is due to law of inertia as we are initially moving with speed 30 mph so the due to inertia of motion of our body after applying brakes we move in the same direction.
Explanation:
As we know by Newton's first law that every object moves in its state of motion or state of rest until and unless some external force will act upon it.
Here we know that car is initially moving with speed 30 mph so our body has state of motion so it will have tendency to move in same direction.
Here when brakes are applied in the car then also our body will move with same speed in same direction due to inertia of motion.
So our body will strike with windshield with the speed of 30 mph.
Answer:
white star
Explanation:
because it is the hottest form of a star
Complete Question
(A) What is the maximum tension possible in a 1.00- millimeter-diameter nylon tennis racket string?
(B) If you want tighter strings, what do you do to prevent breakage: use thinner or thicker strings? Why? What causes strings to break when they are hit by the ball?
The tensile strength of the nylon string is 
Answer:
A
T = 471.3 \ N
B
To prevent breakage the thickness of the string is increased
String breakage when the racket hit the ball is as a result of the string not being thick enough to withstand the increase in tension
Explanation:
From the question we are told that
The diameter is 
The tensile strength of the nylon string is 
Generally the radius is mathematically evaluated as
=> 
=> 
The cross sectional area is mathematically represented as
=> 
=> 
Generally the tensile strength of nylon is mathematically represented as
Where T is the tension on the maximum tension on the string
So
=> 
=> 
Form the equation above we see that
So if the tension is increased to prevent breakage the thickness of the string is increased(i. e the cross-sectional area )
String breakage when the racket hit the ball is as a result of the string not being thick enough to withstand the increase in tension
