When an object is having variable velocity then we can use the definition of acceleration to find it that rate of change in velocity is known as acceleration.

We can define it as

a = \frac{v_f - v_i}{\Delta t}

here

v_f = final velocity

v_i = initial velocity

\Delta t = time interval

now it is given here that final velocity is less than initial velocity after some time which means

v_f < v_i

so here we can say acceleration will have negative value which shows it is opposite to the direction of velocity.

So this is the case of decreasing velocity which is known as <u>deceleration</u>.

So correct answer is

<u>deceleration</u>

Pie

Answer:

The electric bill for June is Rs198000

Explanation:

Convert volt to watt, but in order to do so I need to know the amps and since it is not provided I converted if the amps was 1.

I multiple 50 with 10 then  with 30 so I know how much watt the fan takes at June.

Since there are 2 light bulb I multiple 10 with 2 than with 8 than with 30.

15000 watts for the fan,

4800 watts for light bulb,

add them and then times it by 10.

Rs198000
