Answer:

Resistors with high precision have an extra BAND to indicate a third SIGNIFICANT digit. Therefore, the first three BANDS indicate the significant digits, the fourth band is the multiply factor and the fifth band REPRESENTS the TOLERANCE.

Answer:

Newton Metre SYMBOL:- Nm

Explanation:

The newton-metre (ALSO newton metre; symbol N⋅m or N m) is a unit of torque (also called MOMENT) in the SI system. One newton-metre is equal to the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm that is one metre long.

tunnel diode

A tunnel diode exhibits negative resistance CHARACTERISTICS because this diode is construed with heavily doped p and n regions as result there is no BREAK down effect for reverse VOLTAGE and an extremely NARROW regions.

ANSWER:

SPEED of man=Speed of the image

As MIRROR is stationary and hence speed of image w.r.t mirror will be 15m/sec.

It is only when asked with RESPECT to the man, speed of image can be WRITTEN as=15m/sec−(−15m/sec)=30m/sec

nice QUESTION and take 5.5 cm as 10 cm SORRY I didn't take measurements of line so it get 5.5 cm

The exchange of gases occurs as a result of diffusion down a concentration GRADIENT. Gas molecules move from a region in which they are at HIGH concentration to one in which they are at low concentration. Pulmonary ventilation PROVIDES air to the alveoli for this gas exchange PROCESS....

Explanation:

Advantages of Friction:

Friction is responsible for many types of motion

It helps us walk on the ground

Brakes in a car make use of friction to stop the car

Asteroids are burnt in the atmosphere before REACHING Earth DUE to friction.

It helps in the generation of heat when we rub our hands.

Disadvantages of Friction:

Friction produces unnecessary heat leading to the wastage of energy.

The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects.

Forest fires are caused due to the friction between tree branches.

A lot of MONEY goes into preventing friction and the USUAL wear and tear caused by it by USING techniques like greasing and oiling

Explanation:

To man walking a the rate of 3km/h the RAIN appears to fall vertically

When he increases his speed to  

=6km/h it appears to meet him at an angle of 45° with verticl.

Find the velocity the rain.

Solution  

Let

ANSWER:

pls complete the QUESTION .... how can SOMEONE SOLVE without the figure...

Explanation:

<P>ANSWER:

FORCE = 3.33N AND MOMENTUM= 10 kgm/s

Explanation:

FORCE= mass × acceleration

so acceleration= CHANGE in velocity/ time taken

acceleration= 2-0/3-0

= 2/3 m/s²

force = 5×2/3

= 10/3 N = 3.33N

MOMENTUM= M× CHANGE IN VELOCTIY

P= 5×2 = 10 kgm/s

SPEED = distance/time

=35m/7s

= 5m/s

SOLIDS

Solids have a definite shape and occupy a definite SPACE i.e. solids have a fixed volume. Reason- SINCE MOLECULES are closely PACKED in a solid, they have the least intermolecular space and strong intermolecular force of attraction.

Given:-

• Initial velocity(u) = 0m/s
• Final velocity(v) = 20m/s
• Gravitational force (g) = 10m/s²

To find:-

• Height of the tower.

Solution :-

GRAVITY is CAUSE of an object to fall toward the GROUND surface at a faster velocity, the longer the object falls.

There is a relation between velocity and gravity, 2AS = v² - u², where ACCELERATION(a) = gravity(g) and s = h(height).

✏ From 3rd equation of motion,

Therefore, height of tower is 20m.

Answer:

how does the nuclear density depends on the SIZE of an NUCLEUS

Explanation:

EVERY element has a unique atomic number which is EQUAL to number of protons, which leads to the fact that the mass of nucleus will be DIFFERENT and since different mass results in different density hence nucleus of all elements does not have same density. So the density of nucleus more than that of the atom

A powerful converging lens will focus parallel light RAYS closer to itself and will have a SMALLER focal length than a weak lens. The power of a lens is given by the EQUATION P=1f P = 1 f .

EXPLANATION:

SIN A =p/h

p/h=1/3

p=1,h=3,B=?

by PYTHAGORAS THEOREM

9-1=b^2

b^2=8

b=2√2

cos A=b/h

Answer:

5m/s

Explanation:

s =t²+1

DISTANCE after 2 SEC

s=(2)²+1= 5m

distance after 3 sec

s=(3)²+1= 10m

average speed = total distance covered / total time taken

so AVG speed= 10-5/3-2

so ANSWER IS 5m/s

Explanation:

LATENT heat breaks the forces of attraction between the MOLECULES of a substance and therefore leads to change of state. ... Example : When solid changes to liquid heat ENERGY is ABSORBED and it's known as latent heat of fusion. Latent heat does not cause temperature change.

Answer:

In mechanics and physics, simple HARMONIC MOTION is a special type of periodic motion where the restoring force on the moving OBJECT is directly PROPORTIONAL to the object's displacement magnitude and acts towards the object's equilibrium POSITION.

Explanation:

Potential ENERGY(P.E.) of Particle Performing S.H.M.

You know the restoring force acting on the particle is F= -kx where k is the force constant. ... Thus, potential energy is directly PROPORTIONAL to the square of the displacement, that is P.E. α x2. LEARN the Difference between Periodic and Oscillatory Motion.
