ctric flux coming out from any ONE SURFACE is . If the CHARGE is placed on the CENTER of CUBE. Then, the flux through surface of cube is 6∅

Acceleration is the rate of change of VELOCITY with time. ... Any change in the velocity of an object results in an acceleration: INCREASING speed (what people USUALLY mean when they say acceleration), decreasing speed (ALSO called deceleration or retardation ), or changing direction (called centripetal acceleration )EXPLANATION:hope it hlpz thank u

what I didn't KNOW that ANSWER

i THINK so 6 METERS is the ANSWER

e here is your answer:___________________________________→Frictional force ALWAYS ACTS tangent to the surface.Friction is a RESISTING force which acts on a BODY to prevent or retardd its motion. Friction force always acts tan-gent to the surface at points of contact. Friction force always acts opposite to the direction of motion.___________________________________Hope it HELPS you.

tion:Focal LENGTH (f ) = -15 cmDistance of IMAGE (v) = -10 cm1v–1u=1f1/u = -(1/10) – (1/- 15)1/u =1/15 – 1/101/u = -0.033u = -30 cmso the OBJECT is placed 30 cm away from the concave LENS.

TEMPERATURE :a MEASURE of the warmth or coldness of an object or substance with reference to some standard VALUE. The temperature of two systems is the same when the systems are in thermal EQUILIBRIUM. ... the DEGREE of heat in a living body, NORMALLY about 98.6°F (37°C) in humans.Explanation:hope it helps you

Acceleration is the rate of CHANGE of velocity. Usually, acceleration means the speed is CHANGING, but not ALWAYS. When an object MOVES in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

The NEUTRAL TEMPERATURE of athermocouple is 300° C.Plz MARK as BRAINLIEST

fermentation..EXPLANATION:PLEASE follow me thanks me and also MARK me as BRAINLIEST please!!

is the ANSWER3 RD OPTION

your ANSWER is B PLZ MARK me as BRILLIANT

The Sabine FORMULA is REALLY only valid for ROOMS of relatively low absorption α LESS than about 0.3 because it becomes increasingly INACCURATE as the absorption increases [5].

If 2 raise to the power of a times to be a GOOD PERSON to person who has a lot of things to be a good day for 3 and the FACT.

s DEFINED as the ratio of LENGTH of arc to radius. Substituting in the above formula we GET, Dimensional formula of Angle = M0L0T0. We can also SAY Angle is dimensionless QUANTITY

what does it MEAN???.......

If a frictional force ( damping ) proportional to the velocity is also present, the HARMONIC oscillator is described as a damped oscillator. ... NEWTON's SECOND law takes the form F(t)−kx−cdxdt=md2xdt2 F ( t ) − kx − C d x d t = m d 2 x d t 2 .

G = [M1 L1 T-2] × [L]2 × [M]-2 = [M-1 L3 T-2]. THEREFORE, the GRAVITATIONAL constant is dimensionally represented as M-1 L3 T-2.Explanation:

5×10^-20 OK my DEAR FRIENDS this the ANSWER

Heat = 15000J. Explanation:The amount of heat GENERATED can be CALCULATED using the Joule’s law of heating, which is given by the equation➡ H = I²RTSubstituting the VALUES in the above equation, we get,➡ H = (5)² × 20 × 30➡ H = 15000J. The amount of heat developed by the electric IRON in 30 s is 15000J.

Pierre DE Fermat Explanation:Pierre de Fermat, a French mathematician, stated that the path taken between TWO points by a RAY of light is the path that can be traversed in least TIME. This principle is KNOWS as Fermat's principle or the principle of least time.

Uniform VELOCITY doesn't change with TIME, while variable velocity CHANGES with RESPECT to time.

Quite an easy question to answer...EFFICIENCY of heat ENGINE N = (T2 - T1)/T2where T2 is source TEMPERATURE and T1 is the sink temperature....For n = 0.40.4 = (T2 - T1)/T2T1/T2 = 0.6As T1 = 300 K...... T2 = 300/0.6 = 500KCase 2: for efficiency n to be increased 50% of its ORIGINAL efficiency , i.e. n = 0.4( 1+ 0.5) = 0.6 = 60%Source temperature can be calculated by the same formula n = (T2 - T1)/T20.6 = (T2 - 300)/T2 ………( sink temperature is constant)T2 = 300/0.4 = 750KIncrease in source temperatureDel T = (750 - 500) = 250 K....That's your answer....The source temperature should be increased by 250 K so as to increase the efficiency of heat engine by 50 % of its original efficiency.

fore anyone circumnavigated the globe or went into space, the ancient Greeks had figured out that the Earth is ball-shaped, RATHER than flat The well-known rapper B.o.B has been on a mission to convince his Twitter followers that the Earth is flat.   How can a 16-mile distance between two points in a picture look flat, he questioned: "Where is the CURVE? please explain this." A torrent of similar tweets followed. Many people have tried to reason with him, INCLUDING the astrophysicist and broadcaster Neil deGrasse TYSON. B.o.B has not been swayed.   We at BBC Earth wouldn't usually weigh in on CONSPIRACY theories, but we couldn't let this one go. For one thing "Earth" is in our name, and anyway we think it's fun to know how these big facts about the universe got discovered.

There are numerous uses of concave mirrors in daily life. It is used in the aircraft landing to guide the airplane, it is used as a torch to REFLECT the light RAYS, it is used during shaving to get an erect and enlarged image of the FACE, etc. Some concave MIRROR uses are listed in the points below.Explanation:pleaseeee mark me as brainlest
