Find the uncertainty in a calculated electrical potential difference from the measurements of current and resistance. Electric p

german

Answer:

The value is $\Delta V = 11.5 \ V$

Explanation:

From the question we are told that

The formula for the Electric potential difference is $V = IR$

The current is $I = 9.3 \ A$

The uncertainty of the current is $\Delta I = 0.3 \ A$

The Resistance is $R = 19.7\ Ohms$

The uncertainty of the Resistance is $\Delta R = 0.6 \ Ohms$

Taking the log of both sides of the formula

$log V= log(IR)$

=> $log V= logI+ logR$

differentiating both sides

$\frac{\Delta V}{V} = \frac{\Delta I}{I} + \frac{\Delta R}{R}$

Here V is mathematically evaluated as

$V = 9.3 * 19.7$

$V = 183.21 \ V$

So from

$\Delta V = V * [\frac{\Delta I}{I} +\frac{\Delta R}{R} ]$

$\Delta V = 183.21 [ \frac{0.3 }{9.3} + \frac{0.6}{19.7}]$

=> $\Delta V = 11.5 \ V$

g what process must occur to define an object as a true star? are there any objects that are sometimes placed on an h-r diagram

lesya692 [45]

There must be the presence of Deuterium to define stars. Deuterium fusion, commonly known as deuterium burning, is a nuclear fusion event in which a proton and a deuterium nucleus fuse to generate a helium-3 nucleus in stars and some substellar objects.

The main characteristic that distinguishes genuine stars from ordinary gas-filled balls, or brown dwarfs as they are frequently referred as, is the presence of nuclear fusion at the core. The temperatures are therefore high enough for nuclear fusion to take place, resulting in the fusion of protons to create help. Other items on the h r diagram that aren't necessarily actual stars would be things like white dwarfs and brown dwarfs. Other particles are accepted in the process, but that's kind of the general notion. Particularly for brown dwarfs, they don't actually have fusion taking place. You can plot a star as a point on the H-R diagram once you know its brightness and temperature (or color). With brighter stars positioned higher on the y-axis, plot luminosity.

When a 100-N force acts horizontally on an 8.0-kg chair, the chair moves at a constant speed across the level floor. Which state

TiliK225 [7]

Answer:

The applied force is greater than the frictional force.

Explanation:

the chair moves at a constant speed therefore, the answer is not A or C.

if there is no friction then the chair would accelerate and it would not be at a constant speed.

hence, the only possible answer is B.
