Answer:
Wsep = Wmix
Explanation:
When Cream and milk up in a bottle they might appear homogeneous but after the bottle must have settled down for a while i.e kept in a position without shaking the bottle. the contents ( cream and milk ) will be separated. this is because Milk and cream do not mix up just like some other liquids that don't mix-up. Wmix represents the weight of the bottle before separation while Wsep represents the weight after separation. but since both liquids are in the same bottle the weight after separation would remain the same
Wsep = Wmix

Answer:
Magnetic flux,
Explanation:
Given that,
Number of turns in the solenoid, N = 250
Current in the solenoid is, I = 9 A
Radius of the solenoid, r = 0.075 m
Length of the solenoid, l = 0.14 m
The magnetic flux is given by :
B is the magnetic field
A is the area of cross section
So, the magnetic flux through the circular cross-sectional area at the center of the solenoid is . Hence, this is the required solution.
Explanation:
In order to calculate the work from r = a to r = b we only need to convert 1000 km into 1,000,000 m.
Since, the given data is as follows.
G =
= 1000 kg
a =
b =
=
Now, we will calculate the work as follows.
W =
=
=
thus, we can conclude that work required to launch the satellite is .
Will also have low frequency
