Explanation:

CHARGE will be distributed UNIFORMLY on a surface of a BUBBLE if the bubble is CHARGED

Answer:

A potential difference of 100 V is applied across a resistor of RESISTANCE 50 Ω ... Find the heat produced in 1) JOULE 2) calorie ... Resistance of the resistor, R = 50ohms.

Answer:

it is due to ANGLE of INCIDENT is equal to the angle of the REFLECTION

The p-region of the diode are connected to the ends of the secondary coil.

• When the positive HALF cycle of INPUT a.c signal FLOWS through the primary coil and induced emf will be there. The working of the diode hear is that one diode will be in FORWARD biased and other diode in reverse biased.
• During the negative half cycle the first diode will be in reverse biased and the second diode is the forward biased.
• The wave will going to be rectified and we get the positive half cycle.

Answer:

USING formula E=kQ/r^2

Explanation:

Here k=9*10^9 ,Q =CHARGE and r=1 m

E=81N/C

9*10^9  * Q =81

Q= 9*10^-9 coulomb

F=kQ^2/r^2

F=EQ/4

F=7.29*10^-7/4

F=1.83*10^-7N

Explanation:

Intermolecular FORCES (IMF) are the forces which mediate interaction between molecules, INCLUDING forces of ATTRACTION or repulsion which act between molecules and other TYPES of neighboring particles, e.g. atoms or ions.

Answer:

Hot SOUP is better.

Explanation:

When a soup is hot, the surface tension reduces. THEREFORE, the taste buds can easily SENSE the taste easily.

HOPE IT HELPS YOU

ANSWER:

no WAY FORCE F is the CONSERVATIVE

Explanation:

2m × V + 2m × 0 =( 2m+ 2m) v¹

2mv = 4M v¹

v ¹ = v/2

but as you asked VELOCITY of combination of trolleys the collision can't be elastic

It is PERFECTLY inelastic collision

ANSWER:

Its a property of half WAVE rectifier

which is in FORWARD bias

so +cycle passes through this but block the - cycle

Please MARK me brainliest

Answer:

The DOT product a vector with another vector (in this CASE with itself) is always a scalar. That is why the SQUARE of a vector is a scalar.

the UNITE of UNIVERSAL GRAVITATION G CONSTANT =6.023×10^23

aim :To show that light travels in a STRAIGHT line

materials required: a candle ,a opaque tube

,a table

procedure: Light the candle and PLACE it on the table.Keeping an eye closed see the candle through the tube.note your observations.Now,give a LITTLE BENT to the tube and try to see the candle through the tube.

observation: The candle could be SEEN through the straight tube but when the tube was given a little bent the candle was not seen through the tube.

conclusion: This phenomena is thus proved and also known as rectilinear propagation of light

Answer:

EM wave there are four basic laws of which describe the behaviour of electrical and magnetic fields the relation between them and their gee ration by charges AD currents . These laws are as follows.

Explanation:

1. gauss law for electrostatic which is essentially the Columb slaw describe the relationship between STATIC electric charges and the electric field PRODUCED by them

2. faraday's law which gives the relation between electromotive force (emf) induced In a CIRCUIT when the magnetic FLUX linked with the circuit changes

Answer:

The second law of thermodynamics STATES that the total entropy of an isolated system can NEVER decrease over time, and is constant if and only if all processes are reversible. Isolated systems SPONTANEOUSLY evolve towards thermodynamic EQUILIBRIUM, the state with maximum entropy.

The first law of limiting friction states that ;

The direction of limiting force is always OPPOSITE to the motion of the body!

The magnitude of limiting friction always have a constant ratio with a normal reaction force which acts 2 surfaces internally.

also, it does no depend of rugh surfaces

The DISTANCE of object from the lens is 120 cm  

Explanation:

GIVEN as :

For a converging lens

The measure of focal lens = f = 40 cm

The distance of IMAGE from lens = v = 60 cm

Let The distance of object = u cm

According to question

From lens formula

∵      +  =

So,     =  -  

Or,     =  -  

Or,     =

Or,     =

∴     u = 120 cm

So, The distance of object from the lens is 120 cm  . ANSWER

Matters can be charged with THREE

ways,charging by friction, charging by contact

and charging by induction. When you rub

one MATERIAL to another, they are charged by

friction. Material losing electron is positively

charged and material gaining electron is

negatively charged.

Explanation:

ANSWER:

___________YES_____________

Answer:

Explanation:

Q = 100 microcoulombs = 10^-4 COULOMBS

t = 10 s

CURRENT ( I) = q/t

= 10^-4 / 10

= 10^-5 A

Waves involve the transport of ENERGY WITHOUT the transport of matter. In conclusion, a wave can be described as a disturbance that travels through a MEDIUM, TRANSPORTING energy from one LOCATION (its source) to another location without transporting matter.

Monomers are molecules which can be ADDED together in order get a larger molecule called a polymer. Poly means many and mer means segments.

Copolymers are polymers composed of repeatedly joined TWO or more molecules or in other words having two or more monomers. EG Bakelite is MADE up of two SUBUNITS or monomers that is formaldehyde and phenol. Hope this helps

Answer:

Explanation:

FARADAY's and LENZ's Law

This relationship is known as Faraday's law of induction. The units for emf are volts, as is usual. The minus sign in Faraday's law of induction is very important. The minus MEANS that the emf creates a current I and MAGNETIC field B that oppose the change in flux. —this is known as Lenz's law.
