8.

State Newton's third law of motion?​

Answer»

rd law states that for every action (FORCE) in nature there is an EQUAL and opposite reaction. In other words, if object A exerts a force on object B, then object B ALSO exerts an equal and opposite force on object A. Notice that the forces are exerted on DIFFERENT objects.

A ball is dropped from a height of 20 m. At the same instant another ball is thrown up from the ground with a speed of 20 m/s. When and where will theballs meet?​

Answer»

Choose a FRAME of reference in which the ball thrown upwards is stationary. In other words IMAGINE what it wouldlook like if you were observing from a point on the upward travelling ball. At the START you would be stationary, you would SEE the other ball INITIALLY moving towards you at 20m/s and it would accelerate at g. Use the equations of uniformly accelerated motion (suvat) to find the time it takes for a collision. (s=ut + 1/2 at^2) In this time the upward travelling ball will have covered a distance given by: dist =speed x time =20 x t. This is how far from the floor the collision takes place.Explanation:

The relation between coefficient of absorption, reflection & transmission is a + r + t = 1 * True or false​

Answer»

Absorbance (A) is the flip-side of TRANSMITTANCE and STATES how much of the light the sample absorbed. It is also referred to as “optical density.” Absorbance is calculated as a logarithmic function of T: A = log10 (1/T) = log10 (Io/I). Absorbance to transmittance can also be DETERMINED using this calculator.follow my best friendabidrizvi 5110just click on my FOLLOWING OPTION and follow her

The vi-graph for a non-ohmic conductor is ....linear, non-linear​

Answer»

Not sure about this answerExplanation:Refer to the attachment below for the VI graph of ohmic and non ohmic conductors . ◆Examples of such are, Ohmic conductor - RESISTANCE made of manganin. Non ohmic conductor - Electrolyte. Drawbacks of OHM'S LAW ◆Main drawback of Ohm's law is , when it comes to the terminal of battery or voltage SOURCE, it's not applicable. At terminal of battery, voltage is constant with the RESPECT of current. ◆Only when temperature and given conditions during PROCESS are constant, ohms law is valid.

Answer»

polymeric organic compound has formula (C6H3) (C8H8)nBr3. To Find:If it contains 7.68% bromine, then the value of n will be (approximate)​ ?SOLUTION:since, we know that- formula of the compound = MASS % of the Br, % = 7.68%mass of Br in the compound = 240uNow, LETM = Molecular mass of the compound = 75+104 n +240 = 315+104ntherefore, 7.68% of M =240 u⇒ n ≈ 27Hence, the value of n is 27.

B. What is the relation between pressure,force and area?​

Answer»

When a FORCE is exerted on an object it can change the object's speed, direction of MOVEMENT or shape. Pressure is a measure of how much force is acting upon an AREA. Pressure can be FOUND using the equation pressure = force / area. Therefore, a force acting over a SMALLER area will create more pressure.

Find acceleration of block and tension in strings if m1 =8kg m2= 4kg and take g=10m/s²​

Answer»

TION.=> Mass of block¹ = m¹ = 8kg=> Mass of block² = m² = 4kg=> g = 10m/s²To find the acceleration and tensionin string.=> As we KNOW that first we draw F.B.D of block=> then the block¹ = m¹ moves downward and acceleration is also MOVE downward in the DIRECTION of m¹.=> equation will be written as. => 8G - T = 8a ....... (1) => T - 4g = 4a ....... (2) From equation (1) and (2) we get, => 4g = 12a => 4 X 10 = 12a => 40 = 12a => a = 40/12 = 10/3 m/s²put the value of a = 10/3 in equation (2) we get, => T - 4g = 4 X 10/3 => T - 40 = 40/3 => T = 40/3 + 40 => T = 40 + 120 / 3 => T = 160/3 NTherefore,=> Acceleration = 10/3 m/s².=> Tension = 160/3 N.
