Explain your answer giving reasons.
a carousel starts spinning from rest to 75 radian/s after 5.0s. What is the average angular acceleration of the carousel?
The pressure inside a fire hose is 1.6 x 10^5 Pa and the water inside moves at 0.68 m/s. At the nozzle, the pressure decreases to atmospheric pressure. Using Bernoulli's Principle, determine the velocity of the water exiting the nozzle if there is no change in height
if an object travels around a circle with an angular displacement of 10.5 radians in 3.0 seconds what is its average angular velocity w in (rd/s)
Aleena’s sister who studies in UK coming to Pakistan over winter break. She wants to make a
program that easily calculates the difference between the time of arrival and departure of her
flight.
Write a program that takes in an input from the user for the time of arrival and time of departure
in military format. Using an if/else statement, find the difference in number of hours and minutes
between the two times. Keep in mind that the time of departure is later than the time of arrival
otherwise the program should give an error, “Incorrect Input”.
Zoya parents run a small bakery. They currently do billing manually. Zona decides to help
them by writing a small python program that takes as input the number of each item bought and
prints the total bill amount and change due.
You can create your own 5 items that are sold at the bakery and the price per unit of each item
(get creative!).
The program would ask for the number of each item that the customer is buying, assume that
they will enter 0 for items that the customer is not buying, and print the total amount. Then ask
for the amount the customer hands in and print any change due.
The program should:
● Change any negative numbers input to 0 (for number of item)
● Tell if the amount customer handed in is less than total (and how much the customer still
owes them)
As a air balloon cools down it's composed by the air around it for this process identify the sign of the heat the change in internal energy and the work. Explain your answer
State the first and the second law of thermodynamic in your own word ?
A system undergoes a process consisting of the following two steps
Step 1:the system absorbs 73 J of heat while 35 J of work done is done on it.
Step 2: the system absorbs 35 of j heat while performing 72 J of work
Calculate the change in internal energy for the overall process?
