WEIGHT is nothing but a force W=mg ASTRONAUTS feel lighter on MOON because it has WEAK acceleration due to gravity (g)

Acceleration Due to Gravity Formula                                                                              Near the Earth's surface, the acceleration due to gravity is APPROXIMATELY constant. HOWEVER, at large DISTANCES from the Earth, or around other planets or moons, the acceleration is different. The acceleration due to gravity depends on the mass of the body, the distance from the center of mass, and a constant G, which is called the "UNIVERSAL gravitational constant". Its value is = 6.673 x 10-11 N·m2/kg2.                                                                                       g = acceleration due to gravity (units m/s2)

G = the universal gravitational constant, G = 6.673 x 10-11N·m2kg2

m = mass of a large body (for EXAMPLE, Earth)

r = the distance from the center of mass of the large body

No, displacement can NEVER be greater than distance travelled by the object because displacement is the shorttest path COVERED by a body WHEREAS distance is the TOTAL path covered

Hey MATE!!
you just MISSPELLED the "word" as "wird"

your ANSWER is echolocation

plz MARK BRAINLIEST

Centre of mass can be in EITHER of the directions, as long as it lies on one of the rods.

COM is defined as the point at which we can imagine the whole mass of the body to be concentrated. We can then replace the large complicated OBJECT with the COM of mass EQUAL to the total mass of the body.

The heavier rod in the above QUESTION will have the centre of mass on its side, since their physical features are the same EXCEPT for density of material.

Hey BUDDY,

# Answer- 52.56 micrograms

# Given-

Power = 15W = 15J/s

Time = 10year = 10×365×24×60×60 = 315360000s

# Formula-

Total energy PRODUCED over 10 years is given by

Energy = power × time

Energy = 15 × 315360000

Energy = 4730400000 J

But Energy=mc^2

4730400000=m×(3×10^8)^2

m = 5.256 × 10^−8 kg

m = 52.56 ug

Total mass produced is 52.56 micrograms.

Hope that was useful...

Angle of INCLINATION of a Line. The anglebetween a line and the x-axis. This angle is ALWAYS between 0° and 180°, and is measured counterclockwise from the PART of the x-axis to the RIGHT of the line. Note: All horizontal lines have angle of inclination 0°.

Evaporation cause cooling because When any liquid EVAPORATED it absorves all the heat present on the SURFACE and GET VAPORISE. it is also an exothermic reaction because it absorves the heat hope this will help you and please mark me as brainlist

At। a HEIGHT of 49 m

A neuron (also called neurone or nerve cell) is a cell that carries ELECTRICAL IMPULSES. Neurons are the BASIC units of the nervous SYSTEM and its most important PART is the brain. Every neuron is made of a cell body (also called a soma), dendrites and an axon. Dendrites and axons are nerve fibres.

a SEA diver needs a SPECIAL diver suit because the main motive UNDERWATER is to generate HEAT .so it helps in thermal generation of heat . other reason is that under the water a huge pressure is applied so to counter the pressure suits are worn .

HOPE IT HELPS!!!!

The QUESTION is INCOMPLETE PLZZ COMPLETE it...

Hey buddy,

# Answer- g' = g/9 = 1.09 m/s^2

# Explaination-
Gravitational acceleration due to earth at distance r from earth's CENTRE is GIVEN by
g = GM/r^2

At HEIGHT equal to EARTHS diameter
h = 2R
r = R+h = R+2R = 3R

Gravitational acceleration at h=2R
g' = GM/9R^2
g' = g/9
g' = 9.8/9
g' = 1.09 m/s^2

Gravitational acceleration at height equal to earths diameter is 1.09 m/s^2.

Keep asking...

Given,
m=20kg
u=5m/s
v=2m/s
w=?

w=1/2m(u SQARE -v square)
w=1/2*20(25- 4)
w=10*21
w=210Joule

— HEY HI BUDDY —

» In today's PHYSICS question paper for 1m question they have asked it right !!

> So the question is not n/x it's " ηℓx ".

- It attended it like this :

1. What is ηℓx method ?

2. What is the USE of ηℓx method ?

3. Why do we use ηℓx method only in ATOMIC structure ?

As it is 1m i have created 3 questions on it !!

I don't UNDERSTAND your QUESTION so don't USE shortform

It’s mainly DUE to the number of electrons in their valence SHELL. The ALKALI metals each only have one valence electron, THUS they are the most reactive elements because their nucleus does a POOR job retaining that valence electron. On the other hand, halogens have 7 valence electrons and thus are more electronegative than other elements because they need just one more electron to reach Noble Gas configuration.

Carnot engine is a theoretical thermodynamic cycle proposed by Leonard Carnot. It gives the estimate of the maximum possible efficiency that a heat engine during the CONVERSION process of heat into work and CONVERSELY, working between TWO reservoirs, can possess.

As we KNOW that it isMathematically proven that,
COEFFICIENT of VISCOSITY (η)= Fr/Av    ——- F= tangential Force, AREA, r= distance between the layers, v= velocity.

Dimensional FORMULA of Force = M1L1T-2.
Dimensional Formula of Area= M0L2T0.
Dimensional Formula of distance= M0L1T0.
Dimensional Formula of velocity= M0L1T-1.

Putting these values in above equation we get,

[η]= [M1L1T-2][M0L1T0] / [M0L2T0] [M0L1T-1] = [M1L-1T-1]

Dimensional Formula of Coefficient of viscosity (η)=[M1L-1T-1]
SI unit of Coefficient of viscosity (η) is Pascal-second

✔✔ Hello mate ✔✔

here's your answer  

On gradually INCREASING the load ATTACHED to the wire, the behaviour of the wire changes. At any point in time, we can measure, stress and the corresponding strain.

Initially stress is directly proportional to strain and Hooks law is OBEYED in this region. The region OA is said to be elastic. The point A is called elastic limit.

On further increasing the load attached to the wire, a small increase in stress causes a large increase in strain. This region AA1 is said to be partly elastic and partly plastic.

At the point B called Yield point, the strain begins to increase without the change in stress. The tangent to the point B is parallel to strain.

Next region is called the BREAK down region, where on loading the wire, the wire BECOMES thin and breaks. The point C at which the wire breaks is called breaking point.

Hey dear your answer



In case of NH4CL SALT NH4+ ion coming from base that is NH4OH so that it is a basic Radical and Cl- coming from an ACID HCl so that it is Called Acidic Radical. ... And basic radical is substance left out without a hydroxide ion which is generally a METAL or CATION.'--:-)




The ion formed after removal of Hydrogen ion (H⁺ ion) from an acid is called acid radical. Ex: When HCl loses H⁺ ion, it forms Cl⁻ which is an acid radical.

Key structural differences in the brains of parrots explain the birds' ability to IMITATE sounds and human speech. Scientists have DISCOVERED how parrots TALK, as they believe it's down to the wiring in their brains. ... Parrots are one of the few ANIMALS considered 'vocal learners' meaning they can imitate sounds.

Diamonds exhibit multiple REFLECTION. Light GETS reflected at various angles due to this reason, which In turn CAUSES the diamond to “SPARKLE”.
