You got the formulas on the sheet on the top :) So just use those, exchanging v (as in velocity, expressed in m/s) and the d (in meters) and t (in seconds). Hope you will manage it.
Answer:
2.30 atm
Explanation:
Using Boyle's law :-
This can be written as:-
Given ,
For Bulb 1
Pressure = 7.25 atm
Volume = 51.0 mL
For Bulb 2
Pressure = 1.18 atm
Volume = 250 mL
For Bulb 3
Volume = 45.0 mL
Pressure = 5.96 atm
Given that the volume of the tubing = 47.0 mL
Volume of the whole system = Sum of the volume of the three bulbs + Volume of the tubing
Also, Total volume, V = 51.0 + 250 + 45.0 +47.0 mL = 393 mL
Using above equation as:
We get, Total pressure, P = 2.30 atm

my name jeff hahahhahahahahahhahhahhahhahhahhah the correct a
Explanation:
Answer: a) 335.8 μm; b) keeping the same radius, the new has double potential, V=1340V so if teh radius is also double the potentail is the same (V=670V).
Explanation: In order to explain this problem we have to consider the potential given for sphere respect to infinity ( V=0) in the form:
V=k*Q/R the we have
R=k*Q/V= 9*10^9*25*10^-12/670=335.8 *10^-6 m
When two drop join to form a single drop (considering with the same radius) we have:
V=k*2Q/R
So the new V is double the original,
V=9*10^9*2*25*10^-12/335.8*10^-6=1340V
if the final single drop has a 2R of radius so
V=k*2Q/2R= 670 V
It has the same original potential.
Answer:
Mass = 30.46 kg
Explanation:
Given the following data;
Spring constant = 45 N/m
Acceleration = 1.3 m/s²
Extension = 0.88 m
To find the mass of the box;
First of all, we would determine the force acting on the spring.
Force = spring constant * extension
Force = 45 * 0.88
Force = 39.6 N
Next, we find the mass using Newton's second equation of motion.
Force = mass * acceleration
39.6 = mass * 1.3
Mass = 39.6/1.3
Mass = 30.46 kg
