Answer:

\Delta t = (\Delta x)/(v) \n\n

Explanation:

Given the expression v\:=(\Delta x)/(\Delta t), we are to find the value of Δt from the expression. To find Δt, we will make Δt the subject of the formula from the given expression as shown;

v\:=(\Delta x)/(\Delta t)\n\ncross\ multiply\n\nv*\Delta t = \Delta x\n\nDivide \ both\ sides \ of\ the \ resulting \ equation \ by \ v\n\n(v*\Delta t)/(v) = (\Delta x)/(v) \n\n\Delta t = (\Delta x)/(v) \n\n

Hence the equivalent expression for\Delta t = (\Delta x)/(v) \n\n.

Why voltmeter and resistence are parallel in ohm's law.

Answers

Never mind Ohm's Law.  A voltmeter measures the difference in electrical potential
between two points.  So if you want to measure the difference in electrical potential
between two points, you touch one probe of the meter to each point, and somehow
the internal guts of the meter are able to sense the difference in electrical potential
between the two points.

If the two points have non-reactive impedance (a resistance) between them, then the
difference in electrical potential between the two points, as indicated by the meter,
will be close to (resistance between the two points) x (current flowing between them).

Explanation:

Is an object moving in uniform circular motion accelerating?

Answers

Yes.

-- 'Acceleration' does NOT mean 'speeding up'.
It means ANY change in the speed OR direction of motion ...
speeding up, slowing down, or turning.

-- If an object is NOT moving in  straight line at constant speed,
then its motion is accelerated.

-- In circular motion, or even just going around a curve,
the object is accelerating, because its direction is constantly
changing, even if its speed is constant.
