Answer:
b)
Explanation:
From the options provided, the only drawback of using digital medical records is that Digital medical records might be impossible to access in a power outage. This is because digital records are saved on a database either locally or remotely. Regardless of which, the records can only be accessed through an authorized computer system that is connected to the database. These are electronic systems that require power to function. Without power you would not be able to use the computer and therefore, would not have access to the medical records. Unlike, paper records which can be accessed regardless of whether there is power or not.
Answer:
Each climber had to eat 72 slices of bread to compensate for the increase of the gravitational potential energy of the system climbers-Earth
Explanation:
Hi
One piece of bread releases about of energy in the body, but efficiency in converting the body's chemical energy into mechanical work is 9.5 %, so .
On the other hand, we need to calculate the total work to reach the top of Mt. Everest
, so
Finally, we have that
Refractive index(n)= speed of light in vacuum/ speed of light in medium.
Since refractive index is 1.11, and usually we know that the speed of light is 300,000km/s, simply divide 300,000km/s over 1.11. That is, 270,270.2703 when simply rounding, its 270,270 km/s.
Answer:
The electric force acting on the raindrop is 100 N.
Explanation:
Given;
charge of the raindrop, Q = 10 mC = 0.01 C
electric field strength, E = 10,000 V/m = 10,000 N/C
The force acting on the raindrop is given as;
Electric Force = electric field strength x charge of the raindrop
F = EQ
F = (10,000 N/C) (0.01 C)
F = 100 N
Therefore, the electric force acting on the raindrop is 100 N.
Answer:
The angle between the electric field lines and the equipotential surface is 90 degree.
Explanation:
The equipotential surfaces are the surface on which the electric potential is same. The work done in moving a charge from one point to another on an equipotential surface is always zero.
The electric field lines are always perpendicular to the equipotential surface.
As
For equipotential surface, dV = 0 so
The dot product of two non zero vectors is zero, if they are perpendicular to each other.
