Answer:
Equation of Kinematics: These are the various relations between u, v, a, t and s for the particle moving with uniform acceleration where the notations are used as:
Equations of motion can be written as
V = U + at
V2 =U2+ 2as
Where, U = Initial velocity, V = Final velocity, g= Acceleration, t = time, and h= height/Distance covered
Where u = Initial velocity of the particle at time t = 0 sec
v = Final velocity at time t sec
a = Acceleration of the particle
s = Distance travelled in time t sec
CALCULATION:
Given - Initial velocity (U) = 10 m/s, Final velocity (V) = 20 m/s and time (t) = 5 sec
Acceleration can be calculated by using equations of motion
⇒V = U + at
The glass bangle industry has many health hazards. It usually employs small children. It is illegal to employ a very young children is hazardous industries, but certain force is like middleman, moneylenders, police and politicians combine to entrap the poor workers.
Let us first consider the places where bangle makers work. It is a cottage industry. They work in the glass furnaces with high temperatures. The dingy cells are without air and light. Boys and girls work hard during day next to lines of flames of flickering oil lamps.
They weld pieces of coloured glass in two circles of bangles. Their eyes or more adjusted to the dark than to the light outside. That's why, they often end up losing their eyesight before they become adults.
Glass blowing, welding and soldering pieces of glass are all health hazards. Even the dust from polishing the glass of bangles adversely affects the eyes and even adults go blind. Thus, the surroundings, prevailing conditions and the type of job involved all prove risky to the health of workers.
