_______________________

★ Gɪᴠᴇɴ :-

• MASS of body = 2kg
• Work done = 500 J
• Distance = 10 m

__________________________

★ Tᴏ Fɪɴᴅ :-

• Speed of body = ?

__________________________

★ Sᴏʟᴜᴛɪᴏɴ :-

To FIND , speed of the body firstly we NEED to find force ACTING on the body & acceleration acted .

As we know that ,

W = F × S

Where,

• W → work = 500J
• F → force = ?
• S → distance = 10m

Substituting the values we have,

➠ 500 = F × 10

➠ 500 ÷ 10 = F

➠ Force = 50 NF = m × a

➠ 50 = 2 × a

➠ 50/2 = a

➠ acceleration = 25 m/s²

________________________

Now , finding speed of the body Using ,

v² = u² + 2( aₙₑₜ )S

Where,

• v → final velocity = ?
• u → initial velocity = 0 m/s
• aₙₑₜ → net acceleration = 25 m/s²
• S → distance = 10m

Note :- Here , the initial velocity ( u ) will be 0 m/s , because the body is STARTING from rest.

➥ v² = 0² + 2(25)(10)

➥ v² = 500

➥ v = √500

➥ v = 10√5 m/s

Hence , speed of the body is 10√2 m/s

__________________________

t = 2sec

Explanation:

Retardation (a) = -10m/s²

Velocity (v) = 72km/h => 72×5/18 => 20m/s

Initial velocity (U) = 0

Time (t) = ?

We know ,

★ v = u + at ★

➞ 20 = 0 + -10 × t

➞ 20 = -10t

➞ t = 20/10

➞ t = 2sec

A PERSON 'walks along' the “sides of a square FIELD” each side is “100m long”. Then find the MAXIMUM 'magnitude of displacement' of the person in 'any time interval'. Solution: The maximum displacement is equal to the diagonal of the 'square field

ong>Answer:

FOCAL length of the LENS (f) = 5 cm. We know, convex MIRROR always forms the VIRTUAL, upright and diminished.Also, Object distance in the convex mirror is always negative where as IMAGE distance and focal length are positive. so the image distance (v) =3.33cm.

Correct question:-

A bus starting from REST MOVES with UNIFORM acceleration of 0.1m/s² for 2 MINUTES.Find : (i)the speed acquired

(ii)the distance travelled

Given:-

→Initial velocity of the bus=0

→Time taken=2 minutes

→Acceleration of the bus=0.1m/s²

To find:-

→Speed/Velocity acquired(Final velocity)

Solution:-

Here,we can see that the time is given in minutes,so we shall firstly convert the time into seconds.

=>1 minute=60 seconds

=>2minutes=2(60)

=>120 seconds

By using the 1st equation of MOTION,we get:-

=>v=u+at

=>v=0+(0.1)120

=>v=12m/s

Now,by using the 2nd equation of motion,we get:-

=>s=ut+1/2at²

=>s=0×120+1/2×0.1×(120)²

=>s=0.05×120×120

=>s=720m

Thus:-

→Speed acquired by the bus is 12m/s.

→The distance travelled is 720m.

onversion needed , the MAGNITUDE of both the SI UNITS are equal.

It can be proved as follows:-

V=E*d

Let, the unit of 'E' be N/C

Therefore,

V=N*m/C

OR, V/m =N/C

Hence , proved.

ANSWER

(i) Loudness of SOUND is directly proportional to the square of AMPLITUDE i.e.,

Loudness (L)∝a2

Ratio of Loudness =L2L1=a22a12=(4)2(3)2=169=9:16

(ii) CHANGE in amplitude of a sound does not affect its frequency.

∴ Ratio of frequencies remains same =1:1

what is this?

EXPLANATION:

PLEASE tell me

Explanation:

LET Distance between boy and hill = d metres

Total distance traveled by sound = 2d metres

SPEED of sound = 350 m/s

Distance = speed x time

2d = 350 x t

=> d = 175t metres
