In order to persuade the electrons in the wire to flow, you need
a potential difference between the ends of the wire. Then the
electrons will want to get away from the more-negative end and
go to the more-positive end. If both ends of the wire are at the
same potential, then the electrons have no reason to go anywhere,
and they just stay where they are.
Choice-d says this.
Explanation:
We assume kinetic and potential energy changes are negligible and there is no work interactions.
a) Taking tank as a system, The energy balance can be define as
The mass balance could be written as
The final pressure in the tank could be defined as following
from standard steam table we know at
b)
From steam table at
initial mass in the tank could be define as
Final mass in the tank could be define as
The amount of steam that has entered the tank
c)
The internal energy in final state could be defined as following
The heat transfer could be defined as following
Answer:
$25
Explanation:
The computation of the intrinsic value of the stock is shown below:
As we know that
Intrinsic value or Price = Dividend ÷ (Cost of equity - growth rate)
where,
Cost of equity or ke is
= Risk free rate of return + beta × (Market rate of return - risk free rate of return)
= 6% + 0.75 × (14% - 6%)
= 12 %
So the intrinsic value is
= $1.50 ÷ (12% - 6%)
= $25
Answer: An object is in motion when its distance from another object is changing . A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. You assume that the reference point is stationary, or not moving
