cal substance is a form of matter having CONSTANT chemical composition and characteristic PROPERTIES. Some references add that chemical substance cannot be separated into its constituent ELEMENTS by physical separation METHODS, i.e., without BREAKING chemical bonds

tion:=>voltsIn the International System of Units (SI), electric potential is expressed in units of JOULES per coulomb (i.e., VOLTS), and differences in potential ENERGY are measured with a VOLTMETER.

The PACKET is DROPPED from the height of 176.4mExplanation:Hope this answer was HELPFUL for you. ❤❤❤❤❤❤

While calipers are the most typical USE of VERNIER scales today, they were originally developed for angle-measuring instruments such as astronomical quadrants. In some languages, the vernier scale is called a nonius after Portuguese MATHEMATICIAN, cosmographer PEDRO Nunes (Latin PETRUS Nonius, 1502–1578).

ate here is your answer The component of velocity of MAN in OPPOSITE DIRECTION of the FLOW is 0.5×Cos(180  0 −120  0 )=0.25m/s so the velocity of flow(STREAM) will also be 0.25m/s  so that the person can oppose the stream and in result he will not be drifted by the stream and will reach directly opposite side.the answer is 0.25m/s hope it helps you

Explanation:Halogens share MANY similar PROPERTIES INCLUDING: They all form acids when COMBINED with hydrogen. They are all fairly toxic. They READILY combine with metals to form salts.

c) is RIGHT answer Explanation:hope ITZ helps U no SPAM pls

tion:If both the forces interchange their POSITION as WELL as directions with each other, there would be no change in resultant. As the measure of ANGLE would be same IE ` theta,` the resultant would be UNCHANGED/ same ie.[P^2+Q^2+2PQcos(theta)]^1/2.

A 2-cm-tall object is placed 400 MM from a converging LENS, which is observed to form an image three times the size of the object. To make the image FIVE times the size of the object, the object-lens distance (in mm) must be CHANGED to:Read more on Sarthaks.com - HTTPS://www.sarthaks.com/396622/tall-object-placed-from-converging-lens-which-observed-form-image-three-times-size-objectExplanation:Mark me as brainliest

Let VA be the potential at POINT A and VB be the potential at point B. Therefore, the potential difference between points A and B is 4V. NOTE: Potential difference between TWO points A and B can be DEFINED as the change in amount of potential ENERGY of a charge while moving from point A to point B.hope it helps dear

μ0 = 4π ×10-7 is the VALUE of MUE in SI UNIT.

give up acceleration of body from time zero to t And EQUATION will be: 1/2 (a^2)If had a doubt TRY differentiating such equations as in this CASE DIFFERENTIATION of given answer will COME out to be velocity...

a lot to do with the voice of my FAMILY is that you have a good relationship and a great deal for the doctor who have been there for the doctor who will HELP you have the best of your PICTURE of your child is not just the ONE that is this one and more of you are not just about the voice of the same situation and more INFORMATION about your PICTURE

your ANSWER is in the ATTACHMENT.

A CAR STARTS with an INITIAL VELOCITY 5 m/s andits velocity becomes 15 m/s after 2 sec thenacceleration of car is 75m/s^

tion:The volume of a liquid FLOWING out per SECOND of a pipe of length l and radius r is writtenby a student as v=π8Pr4ηll where P is the pressure difference between the two ENDS of thepipe and η is coefficient of viscosity of the liquid having dimensional formula ML-1T -1 .Check WHETHER the EQUATION is dimensionally correct.

:-HEATER 'A' will generate more heat than heater 'B' .Explanation :-For heater A :-→ Potential difference = 230 V→ Time = 5 MINS = 300 sec→ Resistance = 100 ΩSo, amount of heat generated :-H = V²t/R⇒ H = (230)² × 300/100⇒ H = 52900 × 3⇒ H = 158700 JFor heater B :-→ Potential difference = 230 V→ Time = 300 sec→ Resistance = 1000 ΩAmount of heat generated :-H = V²t/R⇒ H = (230)² × 300/1000⇒ H = 52900 × 0.3⇒ H = 15870 J______________________________Simply, 158700 J > 15870 J .So, heater A GENERATES more heat .

gravity, also called gravitation, in mechanics, the UNIVERSAL force of attraction acting between all MATTER. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass EXERTS on them. Gravity is measured by the acceleration that it gives to FREELY FALLING objects.

You WANT to be at LEAST ONE of the GIRL

In third-class levers the mechanical advantage is ALWAYS less than 1 because the LOAD arm is always longer than the effort arm. In the FORMULA it's MA= effort divided by load which MAKES it less than one.

Explanation:Given values ⇒1.29 1.33 1.34 1.35 1.32 1.36 1.30 and 1.33Now, there are TOTAL of the 8 term.Mean value = Sum of all theobservations/No. of observations.:: Mean value = (1.29 + 1.33 + 1.34 +1.35 +1.32 +1.36 +1.30 + 1.33)/8= 10.62/8= 1.3275= 1.33Now, for ABSOLUTE ERROR in each term,X₁11.33- 1.291 = 0.04X₂ = 11.33 -1.33/ = 0.00X3 = 11.33 1.34/= 0.01X4 11.33 1.35/= 0.02Xs = /1.33 - 132| = 0.01X6 = 11.33 1.36/= 0.03X7 = 11.33 1.30l = 0.03Xg = 11.33 1.33/ = 0.00.: Mean Absolute error = (0.04 + 0.00 + 0.01 +0.02 +0.01 +0.03 +0.03 +0.00)/8:: Mean Absolute error = (0.04 + 0.00 +0.01 +0.02 +0.01 + 0.03 +0.03 + 0.00)/8= 0.14/8= 0.0175= 0.018Vol 49.: Relative Error = Mean absolute error/ Mean Value= 0.018/1.33= 0.135= 0.12:: % Error = 0.12 × 100% Error = 12%Hope it helps. :-)

in FIRST situation ELECTRIC FIELD at centre is not equal to ZERO

= V3 because POTENTIAL DIFFERENCE is same in a PARALLEL CONNECTION.

0.5 MM WOULD be the LEAST COUNT.
