Two points are given in polar coordinates by : (r, θ) = (2.60 m, 50.0°)

alukav5142 [94]

Answer:

The distance between the 2 points is 4.6558 meters.

Explanation:

The distance between 2 points $(r_1,\theta _1),(r_2,\theta _2)$ is given by

$d=\sqrt{r_{1}^{2}+r_{2}^{2}-2r_1\cdot r_2cos(\theta _2-\theta _1)}$

In our case the given 2 points are $(2.60,50.0^{o}),(3.60,-46.0^{o})$ hence the distance is

$d=\sqrt{2.60^{2}+3.60^{2}-2\cdot 2.60\cdot 3.60\cdot cos(-46.0-50)}\\\\\therefore d=4.6558m$

Which components of static electricity does a photocopier use?

Salsk061 [2.6K]

Answer:

For a photocopier to work, a field of positive charges must be generated on the surface of both the drum and the copy paper. These tasks are accomplished by the corona wires. These wires are subjected to a high voltage, which they subsequently transfer to the drum and paper in the form of static electricity.

. A magnetic field has a magnitude of 0.078 T and is uniform over a circular surface whose radius is 0.10 m. The field is orient

Dmitriy789 [7]

Answer:

The magnetic flux through surface is $2.22 \times 10^{-3}$ Wb

Explanation:

Given :

Magnitude of magnetic field $B = 0.078$ T

Radius of circle $r = 0.10$ m

Angle between field and surface normal $\theta =$ 25°

From the formula of flux,

$\phi = B.A$

$\phi = BA\cos \theta$

Where $\theta =$ angle between magnetic field line and surface normal, $A =$ area of circular surface.

$A = \pi r^{2}$

$A = 3.14 \times (0.10) ^{2}$

$A = 0.0314$ $m^{2}$

Magnetic flux is given by,

$\phi = 0.078 \times 0.0314 \times \cos 25$

$\phi = 2.22 \times 10^{-3}$ Wb

Therefore, the magnetic flux through surface is $2.22 \times 10^{-3}$ Wb

The first law of thermodynamics is sometimes called

Leona [35]

Answer:

d) Law of Conservation of Energy

Explanation:

The first law of thermodynamics states that energy can neither be created nor destroyed; energy can only change from one form to another.

For multiple choice you can use an elimination method. If you remember the law then you know it's not A or C because "energy cannot be created nor destroyed", and it's not B because it has nothing to do with mass.

Hope this helps!
