A force of 75 N is exerted on a 45 kg sofa, and the sofa ismoved 5 m. How much work is done moving the sofa?

Answer»

Given:-

  • Force exerted on sofa (F) = 75N.

  • Mass of sofa (m) = 45kg.

  • Displacement (d) = 5m.

To Find:-

  • Work is done moving the sofa (W).

Solution:-

The work done by a force acting on the object is equal to the product of force and displacement of the object in the direction of force.

Work done = Force × Displacement

W = Fd

Put the value which is given above we get,

⟹ W = 75×5

⟹ W = 375 JOULE.

The work is done moving the sofa is 375 J.

More Information!!!

✧ Product of mass and acceleration is CALLED force.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀OR

A push or pull of an object is called force.

✧ SI unit of Force is Newton.

✧ It is denoted by N.

✧ Force is vector QUANTITY i.e., both Magnitude and direction.

✧ SI unit of work done is Joule.

✧ Mathematical term

⟹ Force = Mass×Acceleration

(a) define average speed (b) a bus travel a distance of 120 km with a speed of 40 km/h and reaturn with a speed of 30km/h calculate the average speed for the entire jouy

Answer»

Answer:

hey...

Explanation:

a-  Average speed is calculated by dividing the total distance that something has traveled by the total amount of TIME it took it to travel that distance. Speed is how FAST something is going at a PARTICULAR moment. Average speed MEASURES the average rate of speed over the extent of a trip.

b- T1 = 120/40 = 3hr. Average speed = Total distance covered/Total time taken = 240/7=34.28Km/hr.

Equal heat is given to two objects A and B mass 1 kg temperature of A increases by 3°c and B by 5°c Which object has more specific heat?And by what factor?

Answer»

Answer:

hey...

Explanation:

Let the AMOUNT of the Heat energy transferred to both the objects be Q.

For the Object A,

Mass = 1 g.

Rise in TEMPERATURE = 3 °C

∵ Specific Heat Capacity = Heat Taken/Mass × Rise in temperature.  

  cₐ = Q/1 × 3  

  cₐ = Q/3

Q = 3 cₐ

For the Object B,  

Mass = 1 g.

Rise in temperature = 5 °C.

Specific Heat capacity = Q/1 × 5

= Q/5

∴ Q = 5 cₓ

 ∴ 3 cₐ = 5 cₓ

 ∴ cₐ = 5/3 × cₓ

∵  cₐ >  

Hence, the Specific heat capacity of the Object is more than the B.  

Hope it helps.

Write the function of eardrum inside the ear ​

Answer»

Answer:

EARDRUM is a REALLY important part of your ear. SOUND waves travel through the ear canal to reach the eardrum. The eardrum is a thin flap of skin that is stretched tight like a drum and VIBRATES when sound hits it. These vibrations move the tiny bones of the middle ear, which send vibrations to the inner ear.

10. When do you see a rainbow in the sky?​

Answer» #PHENOMENÅL


Rainbow is defined as the natural phenomenon in which due to dispersion of white light, an arch of seven colors is formed. We see rainbow in the sky only after RAINFALL due to dispersion of sunlight by the TINY water droplets of rain present in the atmosphere. The water droplets ACT like small PRISMS. The rain drops are refracted, dispersed and reflected internally and then refracted again. Due to these phenomena's, we see a rainbow in the sky after rainfall.

What is meant by frequency write it's SI unit ​

Answer»

Answer:-

✧ The number of oscillations of the density of the medium at a place per unit time is called the frequency of sound.

✧ SI unit of Frequency is hertz (Hz).

✧ Frequency is denoted by v (nu).

✧ Relationship between frequency and time period is

V =1/T

Some Related Term:-

Time Period: The time taken to complete ONE oscillation of the density of the medium is called the time period of the sound WAVE.

Wavelength: The minimum distance after which the state of disturbance is repeated in a wave motion is called the wavelength of the wave.

Wave Speed: The speed with which a disturbance propagate in a medium is called wave speed.

Wave Motion: When a source of sound vibrates COMPRESSION and RAREFACTION pulses are produced one after the other pulses TRAVEL one behind the other carrying the disturbance with it. This kind of motion is called wave motion.

Give a reason why mercury is commonly used in the thermometers?

Answer»

Elemental or metallic mercury is used in mercury thermometers and (in combination with silver and other metals) in dental AMALGAM. In China, dental amalgam was used to fill teeth over 1000 years ago (cited in Drexler 1998). Inorganic mercury, e.g. mercury chloride, has been used as a disinfectant.

The reason: Mercury RELEASED into the environment from a broken thermometer is highly poisonous. Pure mercury and its COMPOUNDS can cause neurological problems and other ailments in people exposed to them. ... Federal and state AUTHORITIES have LOBBIED since 2002 for bans on medical mercury thermometers.

For a hydrogen atom what is the excitation energy for the second excited state

Answer»

Answer:

HEY..

Explanation:

The second energy level is -3.4 eV. THUS it would take E2 − E1 = -3.4 eV − -13.6 eV = 10.2 eV to excite the ELECTRON from the ground STATE to the first excited state. If a photon has more energy than the binding energy of the electron then the photon will free the electron from the atom – ionizing it.

Calculate the weight of body mass 5kg

Answer»

ANSWER:

Explanation:

The gravitational force of ATTRACTION due to earth is experienced by all OBJECT on the earth. This force of gravitation on any object is CALLED the weight of that object. Mathematically, the weight of the object of mass  m  is given by the relation,  W=mg, where  g  is the acceleration due to gravity

Here g=10m/s²

so W=mg

W= 5×10

W=50 N

Does pH of solution is depend on temperature .. if yes give formula to calculate pH at given temperature.. do not spam ✌️✌️​

Answer»

Answer:

Temperature plays a significant role on pH measurements. As the temperature rises, molecular VIBRATIONS INCREASE which results in the ability of water to ionise and form more  hydrogen IONS. As a result, the pH will drop. The dissociation of water into hydrogen and hydroxide ion can be represented as:

H2O (l) ⇌ H+ (aq) + OH− (aq)

Please answer fast I will mark you as the Brainiliest​

Answer»

Explanation:

a. I = EMF/ RESISTANCE

= 12 /4

= 3 A.

b. R1 and R2

I¹x 6 = I² x 3

I¹/I² = 1/2

as I = I¹ +I² = 3A

I¹ = 1/3 x 3 = 1A

I² = 2/3 x 3 = 2A

R3, 3A

R4, R5

I⁴x 2 = I⁵ x 2

I⁴/I⁵ = 1

I⁴ = 1/2 x 3 = 1.5A

I⁵ = 1/2 x 3 = 1.5 A

c. PD across AB is

I x R = 3 x 2 = 6V

pd across BC,

Í x R = 3 x 1 = 3V

pd across CD,

I X R = 3 x 1 = 3V

If 'n' number of resistors each equal to R areconnected in series then their equaivalent resistance is(a) nR (b) n²R (c) R/n (d) R/n square​

Answer»

Answer:

The CORRECT OPTION is (a) nR.

Explanation:

Let the number of resistors CONNECTED in series be 3.

Then the effective resistance=R1+R2+R3.

= number of resistors * resistance value.

Here, the number of resistors connected in series is n.

Then the effective resistance = R1+R2+R3+........Rn.

That is also equal to :

number of resistors * resistance value

let the resistance value be R

=n*R

=nR

Therefore the option (a) nR is correct.

The electric field in a region is given by ( ) 3 1 E 2i 3j 10 NC - Ù Ù = + ´rThe electric flux through a rectangular surface 10cm 20cm ´ held parallel to the y z - plane is​

Answer»

EXPLANATION:

Given:

Electric field strength, E⃗ =35E0iˆ+45 E0j⌢,

where E0 = 2.0×103 N/C

The plane of the rectangular surface is parallel to the y-z plane. The normal to the plane of the rectangular surface is ALONG the x axis. Only 35E0i⌢ PASSES perpendicular to the plane; so, only this component of the field will contribute to flux.

On the other hand, 45E0j⌢ moves parallel to the surface.

Surface area of the rectangular surface, a = 0⋅2 m2

Flux,

ϕ=E⃗ .a⃗ =E×aϕ= (35×2×103)×(2×10−1) Nm2/Cϕ=0.24×103 Nm2/Cϕ=240 Nm2/C
