Help me please this read and the question is down blow the read there are 6 question i will post more this like this so please a

nswer the question by the reading.
Mr. Crabbs has created a new sauce that he thinks will reduce the production of body gas associated with eating Crabby patties from the Krusty Krab. He recruits 100 customers with a history of gas problems. He has 50 of them (Group A) eat Crabby patties with the new sauce. The other 50 (Group B) eat Crabby patties with sauce that looks just like new sauce but is really just a mixture of mayonnaise and food coloring. Both groups were told that they were getting the sauce that would reduce gas production. Two hours after eating the Crabby patties, 30 customers in group A reported having fewer gas problems and 8 customers in group B reported having fewer gas problems.

question
What is the control group?
What is the Experimental Group?
What is the Independent Variable?
What is the Dependent Variable?
Is the data qualitative or quantitative? Explain why
What should Mr. Krabs’ conclusion be?

Control group is the group that ate the regular sauce
The experimental group is A, the one that tested the new sauce
The independent variable is the new sauce
The dependent variable is the gas reduction
The data is quantities since it’s in numbers
His conclusion should be the sauce helps lower gas accompanied by Keanu patties since over half of group A Reported having less gas

A car starts from rest and undergoes an acceleration of 4.0 m/s/s for a time of 5.0 s. What is the final velocity of the car?
Kruka [31]

Answer:

20m/s

Explanation:

acceleration=final velocity-initial velocity/time

4.0m/s²=v m/s-0m/s/5.0sec

5.0sec×4.0m/s²=v m/s-0m/s×5.0m/s/5.0m/s

20m/s=v

A rigid tank contains 7 kg of an ideal gas at 5 atm and 30c. a valve is opened, and half of mass of the gas can escape. the fin
Readme [11.4K]
The equation of state for an ideal gas is
pV=nRT
where p is the gas pressure, V the volume, n the number of moles, R the gas constant and T the temperature.

The equation of state for the initial condition of the gas is
p_1 V_1 = n_1 R T_1 (1)
While the same equation for the final condition is
p_2 V_2 = n_2 R T_2 (2)

We know that in the final condition, half of the mass of the gas is escaped. This means that the final volume of the gas is half of the initial volume, and also that the final number of moles is half the initial number of moles, so we can write:
V_1 = 2 V_1
n_1 = 2 n_2
If we substitute these relationship inside (1), and we divide (1) by (2), we get
\frac{p_1}{p_2} = \frac{T_1}{T_2}

And since the initial temperature of the gas is T_1 = 30 C=303 K, we can find the final temperature of the gas:
T_2 = T_1  \frac{p_2}{p_1}=(303 K) \frac{1.5 atm}{5.0 atm}=90.9 K
