<h2>
Answer: Pressure</h2>
<u>Pressure</u> is the force
exerted by a gas, a liquid or a solid on a surface (or area)
.
Its unit according to the International System of Units is Pascal
which is equal to
and its formula is:
Answer:
the potential energy will also change
Explanation:
kinetic energy and potential energy are inversely proportional to each other, so if kinetic energy changes, potential energy will also change..
Answer:
The final position is 36 feet.
Explanation:
initial position, d = 330 feet
speed, v = 3 feet per minute
time, t = 30 minute
now the time is 32 minute
time interval = 2 minute
So, the distance in 2 minutes is
d' = 2 x 3 = 6 feet
So, the final position is
D = 30 + 6 = 36 feet
Answer:
Approximately
(approximately
) assuming that the magnetic field and the wire are both horizontal.
Explanation:
Let
denote the angle between the wire and the magnetic field.
Let
denote the magnitude of the magnetic field.
Let
denote the length of the wire.
Let
denote the current in this wire.
The magnetic force on the wire would be:
.
Because of the
term, the magnetic force on the wire is maximized when the wire is perpendicular to the magnetic field (such that the angle between them is
.)
In this question:
(or, equivalently,
radians, if the calculator is in radian mode.)
.
.
.
Rearrange the equation
to find an expression for
, the current in this wire.
