Answer:
The tension in the part of the cord attached to the textbook is 6.58 N.
Explanation:
Given that,
Mass of textbook = 2.09 kg
Diameter = 0.190 m
Mass of hanging book = 3.08 kg
Distance = 1.26 m
Time interval = 0.800 s
Suppose,we need to calculate the tension in the part of the cord attached to the textbook
We need to calculate the acceleration
Using equation of motion
Put the value into the formula
We need to calculate the tension
When the book is moving with acceleration
Using formula of tension
Hence, The tension in the part of the cord attached to the textbook is 6.58 N.
Answer:
When the pressure and the temperature are increased the volume is 285.7 ml.
Explanation:
We can find the new volume by using the Ideal Gas Law:
Where:
P: is the pressure
V: is the volume
n: is the number of moles
R: is the gas constant
T: is the temperature
Initially, when V₁ = 200 ml, P₁ = 500 torr and T₁ = 10 °C, we have:
(1)
And finally, when P₂ = 700 torr and T₂ = 20 °C, we have:
(2)
By equating (1) with (2):
Therefore, when the pressure and the temperature are increased the volume is 285.7 ml.
I hope it helps you!
