Given :-

• FOCAL length = - 12cm
• Object distance = - 18cm

To FIND :-

• Image distance
• Nature of image
• MAGNIFICATION

Solution :-

Apply mirror formula

→ 1/v + 1/u = 1/f

→ 1/v + (-1)/18 = -1/12

→ 1/v = 1/18 - 1/12

→ 1/v = 2 - 3/36

→ 1/v = -1/36

→ v = - 36cm

Hence,

• Image Distance is -36cm
• Nature of image = REAL and inverted

★ Magnification of mirror ★

→ m = -v/u = hi/ho

→ m = -v/u

→ m = -(-36)/-18

→ m = -36/18

→ m = - 2

Hence,

• Magnification of mirror is - 2

ANSWER:

Heat, air and moisture are the enemies of whole grains. All whole grains should be stored in AIRTIGHT containers with tight-fitting lids or closures. The type of container is a matter of PREFERENCE. Glass, PLASTIC, and ALUMINUM canisters or zip-top plastic bags can all be successfully used, as long as they are airtight.

Explanation:

• When current flows through a conductor, heat energy is generated in the conductor. The heating effect of an electric current depends on three factors: The resistance, R of the conductor. A higher resistance produces more heat.
• The SI unit of energy is JOULE and its commercial unit is kWh.

The RELATIONSHIP between 1 kWh and SI unit of energy is as FOLLOWS:

1 kWh = 1 kW x 1 h

= 1000 W x 3600 s

1 watt - second = 1 joule

1 kWh = 3600000 J

Here is your answer HOPE it helps PLEASE mark me as a BRAINLIST please

Answer:

property that opposes the motion of an object over another is CALLED FRICTION factor affecting friction are NATURE , surface ' SHAPE, temperature, weight of object.

Explanation:

cause of friction are interlocking og surface and adhesion between two surface.

Answer:

A force involves an interaction between two or more objects, and it causes a push or PULL between the objects. There is always a direction associated with the force. GOOD examples of OPPOSING force INCLUDE drag due to interaction with an AIR mass and the force due to friction between two objects.

Answer:

time t=0,the first particle is 300cm from O and moving toward O at a velocity of 20cm/s.

The distance of this particle to O as a function of time is:

A=300−20t

At the time t=0, the second particle is 400CM from O and moving toward O at a velocity of 20m/s.

The distance of this particle to O as a function of time is:

B=400−20t

The distance between the 2 particles can be found using the cosine rule

=400t

2

−14000t+130000

C=

(400t

2

−14000t+130000)

Now one needs to find t such that C will be minimized.

If C is minimized at a certain t, then also C

2

will be minimized at that t.

So INSTEAD of finding the first derivative of C (which is a square root,

so a lot of work), one can simply find the first derivative of C

(a

quadratic expression, which is a lot LESS work)

=800t−14000

800t−14000=0

t=17.5s

At time t=17.5s the distance between the 2 particles is minimized.

The distance at that time will be:

C=

(400×17.5

−14000×17.5+130000)

Answer:

True Solution is a homogeneous mixture of two or more substances in which SUBSTANCE dissolved (solute) in solvent has the particle size of LESS than 10-9 m or 1 nm. Simple solution of sugar in water is an example of true solution. Particles of true solution cannot be filtered through filter paper and are not VISIBLE to naked eye.

Colloidal Solution is a heterogeneous mixture in which particle size of substance is intermediate of true solution and suspension i.e. between 1-1000 nm. Smoke from a fire is example of colloidal system in which tiny particles of solid FLOAT in air. Just like true solutions, Colloidal particles are small enough and cannot be seen through naked eye.They easily PASS through filter paper. But colloidal particles are big enough to be blocked by parchment paper or animal membrane.

Newton's first law postulates that there is (at LEAST) one inertial reference FRAME for every object, in which said object will continue in uniform motion unless acted UPON by a force. WITHOUT the first law to assert that there is indeed a frame in which F=0 implies a=0, the SECOND law is vacuous.

Force:-

• A force is a push or pull upon an object resulting from the object's interaction with another object.

SI unit force is NEWTON (N).

Example:-

examples of opposing force include drag due to interaction with an air mass and the force due to friction between TWO objects.

Types:-

The four basic forces are the

• gravitational force
• electromagnetic force
• weak nuclear force
• strong nuclear force.

George Lucas created the concept of force.

Force cannot be seen but you can see what it can does.

Force can CHANGE the speed of an object.

Force can change the direction of object moving.

Force can change the size of an object.

Force can be measured using a force meter.

Force EXIST all around as all the time.

Comet is a type of an asteroid which travels in space in a periodic motion.

Explanation:

Comet temperature while travelling in space is around –94° FAHRENHEIT (–70° Celsius). So the chances of survival of the micro organism increases.

But I prefer to that microbes FIRST turned in the earth due to the amino ACIDS as the first type of microbes discovered were anaerobic heterotrophic bacteria (the primordial atmosphere was virtually oxygen-free).

And finally about the Panspermia's theory, those are just an assumption made only the POSSIBILITY of living of Earth.
