If you add 2 miles from west then 2 miles east then it would 4 miles all together.
Answer:
Approximately
(assuming that the acceleration due to gravity is
.)
Explanation:
Let
denote the first piston's contact area with the fluid. Let
denote the second piston's contact area with the fluid.
Similarly, let
and
denote the size of the force on the two pistons. Since the person is placing all her weight on the first piston:
.
Since both pistons fit into cylinders, the two contact surfaces must be circles. Keep in mind that the area of a square is equal to
times its radius, squared:
.
.
By Pascal's Law, the pressure on the two pistons should be the same. Pressure is the size of normal force per unit area:
.
For the pressures on the two pistons to match:
.
,
, and
have all been found. The question is asking for
. Rearrange this equation to obtain:
.
Evaluate this expression to obtain the value of
, which represents the force on the piston with the larger diameter:
.
The answer is 40 kg. m/s.
Formula for momentum:
p=mv
p=(10 kg.)(4 m/s)
So, therefore, the final answer is p=40 kg. m/s.
I hope this helped answer your question. Enjoy your day, and take care!
The negative charge comes from the electrons.
An ion is negatively charged means it has more number of electrons compared to protons.
Thus, a negatively-charged ion always has more of ELECTRONS.
Answer:
Electrical Conductivity is 3200 
Solution:
As per the question:

Mobility of electrons, 
Mobility of holes, 
Charge, Q = 
Now,
The formula for the conductivity is given by:
