We repeat the experiment from the video, but this time we connect the wires in parallel rather than in series. Which wire will n

Lady bird [3.3K]

Answer:

Explanation:

The wire which is connected in series will dissipate the most heat.

The reason behind this fact is that, for the wire connected in series, there is only one path for the flow of electrons that's why electron face more opposition and thus more heat dissipation. However, in parallel connecting wires, alternate paths are available for the flow of electrons. That's why the electrons do not face that much opposition as in series case as the path and the flow is divided.

You can understand this concept by the example of traffic on the roads. If there is a single road, then you have to face the more opposition and you will have the less passage to drive through. However if there are parallel roads, then the traffic will got more space to move. It will become easier for them and opposition will be reduced. Hope you understand it :)

find the upward force in Newton when each of these is under water(density of 1g/cm3) a lump of iron of volume 2000cm3

shutvik [7]

Answer:

Upthrust = 19.6 N

Explanation:

When an object is immersed under water, the upward force it experience is called an upthrust. An upthrust is a force which is applied on any object in a fluid which acts in an opposite direction to the direction of the weight of the object.

Upthrust = density of liquid x gravitational force x volume of object

i.e U = ρ x g x vol

Given: ρ = 1g/ $cm^{3}$ (1000 kg/ $m^{3}$ ), volume = 2000 c $m^{3}$ (0.002 $m^{3}$ ) and g = 9.8 m/ $s^{2}$

So that;

U = 1000 x 9.8 x 0.002 (kg/ $m^{3}$ x $m^{3}$ x m/ $s^{2}$ )

= 19.6 Kg m/ $s^{2}$

U = 19.6 Newtons

The upthrust on the iron is 19.6 N.

Fill in the blank below: In a _______________ digestive system, digestion takes place outside of the cells in a series of tubes.

Elina [12.6K]

Answer : Option D) Complete.

Explanation : In a complete digestive system, digestion takes place outside of the cells in a series of tubes. Food enters through one opening and food remnants exit out of a different opening. It has examples of humans, dogs, horses, spiders and earthworms. This system is complete because it does not occurs inside a cell nor it occurs in sponge kind-off organs and it is also not incomplete digestion as the waste products are removed from the other opening.

Therefore, the correct answer is option D) complete.

A wire is formed into a circle having a diameter of 10.0cm and is placed in a uniform magnetic field of 3.00mT . The wire carrie

Paul [167]

The range of potential energies of the wire-field system for different orientations of the circle are -

θ U

0° 375 π x $10^{-7}$

90° 0

180° - 375 π x $10^{-7}$

We have current carrying wire in a form of a circle placed in a uniform magnetic field.

We have to the range of potential energies of the wire-field system for different orientations of the circle.

<h3>What is the formula to calculate the Magnetic Potential Energy?</h3>

The formula to calculate the magnetic potential energy is -

U = M.B = MB cos $$\theta$

where -

M is the Dipole Moment.

B is the Magnetic Field Intensity.

According to the question, we have -

U = M.B = MB cos $$\theta$

We can write M = IA (I is current and A is cross sectional Area)

U = IAB cos $$\theta$

U = Iπ $r^{2}$ B cos $$\theta$

For $$\theta$ = 0° →

U(Max) = MB cos(0) = MB = Iπ $r^{2}$ B = 5 × π × $( 0.05 ) ^{2}$ × 3 × $10^{-3}$ =

375 π x $10^{-7}$ .

For $$\theta$ = 90° →

U = MB cos (90) = 0

For $$\theta$ = 180° →

U(Min) = MB cos(0) = - MB = - Iπ $r^{2}$ B = - 5 × π × $( 0.05 ) ^{2}$ × 3 × $10^{-3}$ =

- 375 π x $10^{-7}$ .

Hence, the range of potential energies of the wire-field system for different orientations of the circle are -

θ U

0° 375 π x $10^{-7}$

90° 0

180° - 375 π x $10^{-7}$
