The length of a minute hand of a clock is 7 cm. Find out the average speed and average velocity (in cm/min) of the tip of the minute hand when it moves during a time interval from 3: 15 pm to 3: 45 pm? fast pls fast​

Answer»

Explanation:

CORRECT option is

C

69.7×10−5

The distance moved by tip of MINUTES hand when it MOVES during a TIME interval from 3 p.m. to 3.45 p.m. is rθ

where, r = LENGTH of minute hand

θ = angle moved by minutes hand

⇒ Distance covered =4×23π=6πcm

⇒distance=6πcm=0.06πm

 ⇒velocity=timedistance 

⇒velocity=45×600.06π=69.7×10−5ms−1

A bus is moving with a velocity 90 km/h. If the bus covers a distance of 625 m before coming to rest, calculate the retardation of the bus.

Answer»

Explanation:

Speed in m/sec. = 90 × 5 / 18 = 25 m/sec.

Using Newton's 3rd law of motion

v^2 - u^2 = 2as

-25^2 = 2 × 625 × a

625 / 2 × 625 = a

a = 1/2

How is CGS unit if density related to SI unit of density​

Answer»

Answer:

The S.I. UNIT of mass is kilogram (SYMBOL kg) and of volume is cubic METRE (symbol m3). Therefore S.I. unit of density is kg/m3 or kg m-3. The C.G.S. unit of mass is gram (symbol g) and of volume is cubic centimetre (symbol CM3). Therefore the C.G.S. unit of density is g/cm3 or g cm-3.

A car travels at a speed of 40 m/s for two hour and then at 60 m/s for 4 hours. What is the average speed of the car (in m/s) during the entire journey?​

Answer»

Answer:

Let the DISTANCE for outward journey = d metre

Time taken to travel the distance d metre at a speed of 40m/s = d/40 second

Time taken to travel distance d on the return journey at a speed of u m/s = d/u second

Total time taken for the outward and return JOURNEYS = (d/40) + (d/u) = d( 1/40 + 1/u) = d [(u + 40)/40 u]

Total distance travelled = d +d = 2 d metre

Average speed = (Total distance travelled) ÷total time taken = 2d ÷ d (u +40)/40 u = 80 u/ u +40 = 48

=> 80 u = 48 u + 48 × 40

=> 80 u - 48 u = 48 × 40

=> 32 u = 48 × 40

=> u = (48 × 40)/32 = 3 × 20 = 60 m/s.

u = 60 m/s.

133.

Calculate the acceleration and distance of the body moving with 15 m/s which comes to rest after travelling for 15 sec?​

Answer»

ANSWER:

here,

u- 15m/s

v- 0

t= 15s

so acceleration is

v-u/t

= -15/15 m/s^-2

= -1m/s^-2

and DISTANCE is EQUAL to (u+v)/2×t

= 15×15/2

=112.5m

What force would be required to accelerate a car of mass 120kg from 5m/s to 25m/s in 2s​

Answer»

Answer:

1200N

Explanation:

Given :

MASS (m) = 120kg

Initial VELOCITY (u) = 5m/s

Final Velocity (V) = 25m/s

Time (t) = 2s

Force = m(v-u)/t

= 120 × (25-5)/2

= 120 × 20/2

= 120 × 10

= 1200N

3) The velocity ofacan at 10:50 am is 60 kmperhour and at10:52 an it is 80kmper hour assumingconstant accelerationwas the given period find the value.​

Answer»

Answer:

Given

▪️Velocity at 10:50 am = 60 km/h

= 60 × 5/18

= 150/9 m/s

▪️Velocity at 10:52 am = 80 km/h

= 80 × 5/18

= 200/9 m/s

▪️Acceleration is constant

Now from above

▪️Time = 2 min = 120 sec

Now as we have

▪️v = U + at

\longrightarrow \dfrac{200}{9}= \dfrac{150}{9} + 120(a)⟶

How can we use liquid pressure

Answer»

ANSWER:

Liquid pressure is the increase in pressure at increasing DEPTHS in a liquid. This pressure increases because the liquid at lower depths has to support all of the WATER above it. We calculate liquid pressure using the EQUATION liquid pressure = mass x acceleration due to g density x depth in fluid.
