Production is carried out in power STATIONS (also called "power plants"). Electricity is most often generated at a power plant by electromechanical generators, primarily driven by HEAT engines FUELED by combustion or nuclear fission but also by other means such as the kinetic energy of flowing WATER and wind.

ong>Explanation:

What is the NUCLEAR stability? Nuclear stability means that nucleus is stable meaning that it does not spontaneously emit any kind of RADIATION. On the other HAND, if the nucleus is unstable, it has the tendency of emitting some kind of radiation, which makes it radioactive. Therefore the radioactivity is associated with unstable nucleus:

Stable nucleus – non-radioactive

Unstable nucleus – radioactive

We want to know why there is a radioactivity. What makes the nucleus stable? There are no concrete theories to explain this, but there are only general observations based on the available stable isotopes. It appears that neutron to PROTON ratio is the dominant FACTOR in nuclear stability. Then how do we predict the nuclear stability? One of the simplest ways of predicting the nuclear stability is based on whether nucleus contains odd/even number of protons and neutrons:

The slope of a velocity graph represents the ACCELERATION of the OBJECT. So, the value of the slope at a PARTICULAR time represents the acceleration of the object at that instant.

Explanation:

RRSCD IYF

EXPLANATION:

let the distance travelled by the body= 2πr

= 2×22/7×21= 2×22×3= 132METER

hence distance travelled by body= 132meter.

and DISPLACEMENT= 0

-6m/s²

Explanation:

INITIAL VELOCITY : 30m/s

final velocity : 0m/s

Time : 5sec

retardation = v-u/t

= 0-30/5

= -30/5

= -6m/s²

ong>Answer:

m^3.kg^-1.s^-2

Explanation:

the MEASURED values of constant is KNOWN with some certanity to four significant digits . in SI UNIT its value is approximately 6.674 ×10^-11 m^3.kg^-1.s^-2.

Given,

Height of fall, H = 50 m

Acceleration due to gravity, g = 10 m/s2

Mass of WATER, m = 8 × 102 kg

Time taken, t = 1 min = 60 s

power = mgh/t= 8*10^2*10*50/60

THEREFORE, the power given to TURBINE = 6.67 × 10^3W

rong>As OBVIOUS as their name, broader TYRES are SIMPLY tyres that are wider than standard on-road tyres. In both wet and dry weather conditions, broader tyres assist braking distance due to increased rolling resistance. This helps to STOP your car in a shorter distance.

RUPTURE means BURST . OPTION b

Answer:The gravitational FORCE of attraction between the two electrons is very much less than that of the electrostatic repulsive force.. So electrostatic force is greater than gravitational force, while the are repulsive and attractive RESPECTIVELY

In audio signal processing and acoustics, ECHO is a REFLECTION of SOUND that arrives at the listener with a DELAY after the direct sound. The delay is directly proportional to the distance of the reflecting surface from the source and the listener.

The correct option is (D) Live with emotions....

Language not understood SORRY about the INCONVENIENCE you FACED

Let’s review the 4 fundamental kinematic equations of MOTION for constant acceleration (suggest you commit these to memory):

s = ut + ½at^2 …. (1)

v^2 = u^2 + 2as …. (2)

v = u + at …. (3)

s = (u + v)t/2 …. (4)

where s is distance, u is INITIAL velocity, v is FINAL velocity, a is acceleration and t is time.

In this case, we know u = 10m/s, v = 50m/s, t = 10s and we want to find a, so we USE equation (3)

v = u + at

50 = 10 + 10t, so t = (50 – 10)/10 = 4m/s^2

The acceleration is 4m/s^2.

ong>Answer:

NEWTON's universal law of gravitation states that when two body are separated by a DISTANCE r, then both attract each other with a force which is directly proportional to the PRODUCT of their masses (m

1

and m

2

) and inversely proportional to the square of distance between them (r). This force is termed as gravitational force.

Mathematically, gravitation force is given by F=GM1×M2/R2
