Answer:

It is a "PERIODIC" comet and returns to Earth's vicinity about every 75 years, making it POSSIBLE for a human to see it TWICE in his or her lifetime. ... The comet is NAMED after English ASTRONOMER Edmond Halley, who examined reports of a comet approaching Earth in 1531, 1607 and 1682.

Answer:

CONDUCTION. Heat is thermal ENERGY. It can be transferred from one place to another byconduction. Metals are good conductors of heat, but non-metals and gases are usually poor conductors. ... Heat energy is CONDUCTED from the HOT end of an object to the cold end.

ANSWER:

ACCELERATION =v-u/t

• v=final POSITION
• u=initial position
• t=time TAKEN

=> Here is your answer....

=> Rotational mechanics

Answer:

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), REPRESENTED by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is ALSO a VECTOR quantity, so it includes both MAGNITUDE and direction.

Answer:

A METEOR is what you see when a space rock falls to Earth. When the meteoroids enter Earth's ATMOSPHERE they are usually going faster than the Earth's escape velocity of 13km/sec or MACH 40. This makes them heat up and usually BREAK apart. When the heat makes them glow, they are KNOWN as meteors.

Explanation:

Self induction:

production of induced EMF in a COIL due to CHANGES in the current in the same coil is called self induction.

↪si unit of self induction is Henry .

↪the self inductance of a coil is EQUAL to the EMF induced in the coil due to the unit rate of change of current in the same coil.

↪ for EXPRESSION refer to attachment.

Answer:

Explanation:

plz mark as brainliest answer , follow me and thx for the BRILLIANT question

Given=R1=R2=2ohms

Internal resistance=r

In parallel CURRENT flows=1.2 A

In series current flows =0.4A

Assuming potential of source remains  constant in both case:

EQUIVALENT resistant in parallel :

Rp=R1R2/R1+R2

=2x2/2+2

=1ohm

Thus , sum of potential drops at individual resistance=total potential difference applied

i(Rp+r)=v

1.2(1+r)=V-----------------1

now for series connection:

Rs=2+2+r=r+4

Thus sum of potential drops at individual resistance=total potential difference applied

iRs=V

0.4x(4+r)=V------------------2

from EQ.  1 and 2

1.2(1+r)=0.4x(4+r)

r=0.5ohms

Answer:

Capacitance of a charged CAPACITOR, C1=4μF=4×10−6F

Supply voltage, V1=200V

Electrostatic energy STORED in C1 is given by,

E1=21C1V12

      =21×4×10−6×(200)2

      =8×10−2J

Capacitance of an uncharged capacitor, C2=2μF=2×10−6F 

When C2 is connected to the circuit, the potential acquired by it is V2.

According to the conservation of CHARGE, initial charge on capacitor C1 is equal to the final charge on capacitors, C1 and C2

∴V2(C1+C2)=C1V1

V2×(4+2)×10−6=4×10−6×200

Answer:

Given:

2 charges are given. There distances are varied and a graph is plotted between Force and Distance .

To find:

The NATURE of the graph

Concept:

The force acting between 2 charges is ELECTROSTATIC Force.

As per Coloumb's Law ,the force is directly proportional to the product of the charges and inversely proportional to the SQUARE of the distance between them

Inserting a constant k:

Since The charges have been SPECIFIED, we can say that the charges are constants . So force will only be dependent on distance between the charges :

So, this EQUATION has the form of a. hyperbola.

Hence Option D) is correct.

ANSWER:

ok

Explanation:

Answer:

Part 1)

Acceleration of A = 2.5 m/s/s

acceleration of B = 10 m/s/s

acceleration of C = 0

so the ascending order of acceleration is

C < A < B

Part 2)

Distance covered by A is 240 m and distance covered by B is 80 m before they meet C

Explanation:

Part 1)

As we know that the acceleration of an object is rate of change in velocity

So here we will have

now we know that if the graph between velocity and time is given then rate of change in velocity is slope of the graph

So we have

acceleration of C = 0

acceleration of A =

acceleration of B =

so the order of acceleration of three are

C < A < B

Part B

Distance covered by B before it meet with C is given by the area under the curve

so we will have

Distance covered by A before it meet with C is given by the area under the curve

so we will have

Anomalous expansion of WATER REFERS to the fact that water, UNLIKE most substances, expands when it freezes. The density of water increases as temperature decreases, but reaches a maximum at 4 degrees C then begins to expand. The significance of this is that ice is less dense than water so it floats in water.

Cyclotron is a device USED to accelerate charged particles to high energies. It was devised by LAWRENCE. ... When a positive ion of charge q and mass m is emitted from the source, it is accelerated TOWARDS the Dee having a negative potential at that instant of time.

The cyclotron frequency of this circular motion is ω c = q B / m and the cyclotron radius is r c = m V ⊥ / q B . Here v⊥ is the magnitude of the particle velocity perpendicular (⊥) to the magnetic field direction.
