With another person on student A’s side. I’m sorry if I wasn’t able to help. Im trying my best from the information given. :)
Answer: It would take 3.23ms
Explanation: Please see the attachments below
A). period is time
b). amplitude can be almost anything that waves . . . length, voltage, pressure, current etc.
But not hertz.
c). frequency ... "oftenness ... reciprocal time. the only item on this list that CAN be measured in Hertz.
d). wavelength ... length units
Answer:
60 km/h
Explanation:
In the first part of the trip, the speed is
v = 80 km/h
while the time interval is
t = 3 h
So, the distance covered is:
d = vt = (80)(3)= 240 km
The problem states that this distance is half distance between home and the destination - so, the total distance between home and the destination is

The time taken to cover the second part of the trip is 5 h, so the total time taken is
T = 3 h + 5 h = 8 h
Therefore, the average velocity for the entire trip is

Answer:
a)
b)
.
Explanation:
Given that
Boyle's law
P V = Constant ,at constant temperature
a)
Given that


We know that for PV=C

Now by putting the values
PV= 50 x 0.106

Where P is in KPa and V is in 
b)
PV= C
Take ln both sides
So 
lnP + lnV =lnC ( C is constant)
By differentiating

So

When P= 50 KPa

It indicates the slope of PV=C curve.
It unit is
.
Or we can say that
.
