Whenever a current carrying CONDUCTOR is placed in a magnetic field, it experiences a FORCE due to the magnetic field. The direction of force acting on the conductor can be FOUND out using Fleming's Left HAND Rule. ...Fleming's Left Hand Rule is used in electric MOTORS which are used in fans, mixers, printers, etc

Potatoinal difference will be same in electric APPLIANCES due to PARALLEL but they are conected in series then potational difference will be not same due to this all appliances will be not work PROPERLY

The PERCENTAGE ERROR in KE is2+6=8%

LET the vertical component be Bv

Horizontal component, Bh

Given, Bv=root3xBh

THEREFORE, tan THETA=Bv/Bh

=ROOT 3 Bh/Bh

=root 3

therefore theta = 60 degree

It HAPENS DUE to INERTIA of MOTION

The gravitational field in a region is given by E = ( 2 i+ 3 j) N/kg. Show that no work is done by the gravitational field when a particle is moved on the LINE 3 y + 2 x = 5.
[Hint : If a line y = mx + c MAKES angle θ with the X-axis, m = tanθ

X - IRON
Y - Copper Sulphate
Fe + CuSO4(aq) ----> FESO4 + Cu
FeSO4 colour is light green
CuSO4 is blue
and after REACTION copper gets DEPOSITED on remaining iron and form reddish coating..
if u like mark as brainleist..

This is done to PREVENT the oily from oxidizing, which is part of what MAKES them GO STALE.

Radius=50cm=1/2m.

The LEWIS notation of the given elements will be as -

• In Lewis representation, an electron dot diagram is constructed based on the number of VALENCE electrons of the given species.
• Firstly, the symbol of the ELEMENT is written, and then the dots in number equal to that of valence electrons are put around it.
• The number of valence electrons is equal to the number of electrons in the OUTERMOST shell of the atom.
• The lewis notation of BERYLLIUM, calcium, and lithium is attached. Kindly refer to it.

element with atomic no 6 cannot form ionic bond EASILY because for the formation of ionic bond it MUST lose or gain 4 electrons .For this it requires more energy.

Element with atomic no 17 cannot form COVALENT bond easily because for the formation of covalent bond it must share 7 electrons which is HIGHLY impossible.

element with atomic no 11 can form both ionic and covalent bond

Hello


This was quite unknown about how gravitational force came into existence .

But latest scientific RESEARCH stated that :-
According to string theory ( it is hypothetical theory and hasn't been proved yet ) , all the THINGS in this universe is made up of strings and their features are RESULT of the movement of strings in PARTICULAR order .

Strings are the basics of every thing.

& the movement of string causes gravitational force ( according to string theory ) . This particular strings partucles are known as " Gravitons " .

A. FORMATION of sodium chloride (NaCl):
1. Sodium chloride is formed from the elements sodium (Na) and chlorine (Cl).
2. When sodium (Na) atom loses one electron to get octet electron configuration, it
FORMS action (Na+
)
3. Now Na+
gets electron configuration that of Neon (Ne) atom.
Na →Na+
e-
4. Chlorine, has storage of one electron to get octet in its valence shell.
5. So, it gains the electron that was lost by Na to form anion and gets electron
configuration of Argon(Ar)
Cl + e-
→ Cl
-
6. Transfer of electrons between Na and Cl atoms, results in the formation of Na+
and
Cl
-
ions.
7. These oppositely charged ions get attracted towards each other due to electrostatic
forces and forms the compound sodium chloride (Nacl)
Na+
+ Cl
- → NaCl
Formation of Calcium OXIDE (CaO):
1. Calcium (Ca) REACTS with Oxygen (O) to from an ionic compound calcium
Oxide(CaO).
2. Calcium atomic NUMBER is 20. Its electronic configuration is 3. 8, 8, 2.
3. Ca→ Ca+2 + 2e-
i.e., calcium losses 2e-
and becomes Ca+2.
4. Oxygen atomic number is 8. Its electronic configuration is 2, 6.
5. 2
2e O O− ⎯⎯⎯−→ i.e., Oxygen 2e-
and becomes O-2.
6. These oppositely charged ions gets attracted towards each other due to electrostatic
forces and form the compound calcium Oxide (CaO)
Ca+2 + O-2 → CaO

Let total distance be 3X

first 1/3 rd at a SPEED of 10 mph

so, TIME = (3x × 1/3)/10 = x/10 h

second 1/3 rd at a speed of 20 mph

so, time = (3x × 1/3)/20 = x/20 h

third 1/3 rd at a speed of 60 mph

so, time = (3x × 1/3)/60 = x/60 h

So, total time = x/10 + x/20 + x/60

= (6x + 3x + x)/60 = 10x/60 = x/6 h

So, average speed = total distance/total time

= 3x / (x/6) = 18 km/h

Strings of Sitar VIBRATE .

ACTUALLY , sitar player himself makes it to vibrate to produce the MUSIC of WHATEVER he WISH to .

30 m
Taking the case of constant acceleration in parts with constant average VELOCITY gives the same answer.
So the distance travelled in 1st second = 5 m
Distance travelled in 2nd second = 10 m
Distance covered in 3rd second = 15 m
Which makes the total distance travelled = 5m + 10M + 15m = 30 m.

Dear STUDENT,

◆ Answer -

(b) Fluorine (Z=9)

● EXPLANATION -

Given that electronic configuration of the UNKNOWN atom is 2, 8, 7.

Electronic configuration of Fluorine will be 2, 7.

As no of ELECTRONS in last orbit of unknown atom are same as that for fluorine, they will be chemically similar.

Thanks dear. Hope this HELPS you..

It will FLOAT on the mercury because the DENSITY and the MASS of mercury is more than the steel ball

Forces that are equal in SIZE but opposite in direction are calledbalanced forces. Balanced forces do not cause a change in the motion of objects. Forces that cause a change in motion of objects are called unbalanced forces. Unbalanced forcescan change the motion of an object in TWO ways....

I hope it help you..

Introduction:

      Ohm’s law states that,

     

Where V. I, and R represent the voltage in volt, current in ampere, and resistance in ohms, respectively, for a resistor or segment of DC circuit. R is the equivalent resistance if the segment CONSISTS of multiple resistors.

Experiment requirement:

Every group will be provided the same equipment as last week including the resistors drawers, a circuit board, cables, and two mulitmeters.

List 1

Components:

R1, R2, R3, R4, and R5

List 2

Circuit segments:

AB, AC, CB

Build a circuit according to the diagram in figure 1 using resistors with nominal values as R1=100Ω, R2=220Ω, R3=1kΩ, R4=2.2kΩ, and R5=1kΩ. A power supply should be connected to points A and B. Vary the voltage setting on power supply from 10 to 20V with at most 1V increment. Choose three different components/segments (at LEAST one from each category in Lists 1 and 2). From these three components/segments, each group member pick one and measure the relevant variables to produce a V vs. I plot. The data and plot should show if the Ohm’s law is satisfied (or not).

Precaution: pick a dedicated mutlimeter as an ammeter and fix its scale to 200mA. This will avoid a multimeter from switching between ammeter and voltmeter, which can easily blow the fuse. Use the other multimeter when measuring resistance and voltage.

Lab report requirement:

State your procedure clearly. Describe data analysis including uncertainties. Include enough details in your data table(s) and plots. CITE your data and plots to support your conclusion.

Hint:

You can use measured R and I to calculate V, then compare it with measured V, or

You can fit V vs. I plot with linear function, then compare the slope (should be R) with the measured R.

These are two common approaches, but you are not LIMITED to them. For whichever approach you pick, make sure you understand the uncertainties involved.

HW: i need help just writing the procedure .

1. Don't need intro. and theory SINCE it's a simple equation. Don't need circuit diagrams since they are given.

2. Write up your procedure: pick three segments/components as required in lab instruction, describe your data collection/analysis/plot. How can you tell if the Ohm's law is satisfied or not?

3. Application of Ohm's law: calculate V and I for every resistor using resistor's nominal value and 10 V between points A and B in circuit.

HEYA MATE,

HERE IS UR ANSWER.

Thanks for asking this QUESTION.

1.COW dung cake has low calorific value i.e. 3.1kJ/g than the Methane gas (5.5kJ/g), a biogas constituent.

2.Bio gas is a clean fuel that burns WITHOUT smoke and leaves no ash, unlike cow dung.

3.The by-product os biogas PLANTS i.e. the spent slurry, being rich in nitrogen and phosphorus is a good manure.
