y has an INITIAL velocity u at a point A and then its velocity changes at a uniform RATE from A to B in time t. In other words, there is a uniform ACCELERATION a from A to B, and after time t its final velocity becomes v which is equal to BC in the graph. The time t is represented by OC. To complete the figure, we draw the perpendicular CB from point C, and draw AD parallel to OC. BE is the perpendicular from point B to OE. Now, Initial velocity of the body, u=OA ...(1) And, Final velocity of the body, v=BC ...(2) But from the graph BC=BD+DCTherefore, v=BD+DC ...(3) Again DC=OASo, v=BD+OANow, from equation (1), OA=uSo, v=BD+u ...(4) We should find out the value of BD now. We know the slope of a velocity-time graph is equal to the acceleration, a. Thus, Acceleration, a= slope of line ABor a= ADBD But AD=OC=t, so PUTTING t in place of AD in the above relation, we get: a= tBD or BD=atNow, putting this value of BD in equation(4), we get: v=u+atsolution

nitude of GIVEN TWO vectors are 4 units and 6 units and they act at an ANGLE of 60 ° . So the RESULTANT will be ,

a BODY of MASS m is moving with velocity v. It is BROUGHT to rest by applying a retarding FORCE F. Suppose it traverses a distance s before coming to rest. Kinetic energy of body, KE = Work done by retarding force to stop it.

A CONVEX LENS MADE of glass is IMMERSED in water.As a result,its focal length will increase. 2. Its height MUST be greater than the focal length of lens.

decreases between POINTS O to AEXPLANATION:this is because from A to B the value of the angle (theta) between the graph and the time axis decreases and with DECREASE in the value of theta the value of displacement decreases.

4ij I THINK so this is the ANSWER

deration refers to members taking a step back and evaluating their ENVIRONMENT and their own behavior and then taking STEPS to either CORRECT their behavior or REMOVE themselves from an environment that isn't good for them.

Ethylene is a gasExplanation:This is known as “fruit-ripening hormone.” EVERY fruit has a certain level of ethylene production throughout its lifecycle. However, in some FRUITS, ethylene LEVELS SHOOT up when the fruit starts ripening.

that a floating body is PUSHED up with a force equal to the gravity of the DISPLACED fluid.Now the question is: What volume of water we need to displace in order to generate a force equal to the gravity of the cube?The mass of the cube = V x Density=0,6kgGravity of the cube is approximately 60N so we need to find out what is the height of a water COLUMN with area 0,1 x 0,1 that has a gravity of 60N. ASSUMING water density 1g/cm3 you can calculate the height being 0,06m (6cm). The answer to the question is 4cm.If is not CLEAR I can write down on a piece of paper. Al you need to know to figure it out by yourself is Archimedes formula and Density formula.

Pitch is related to FREQUENCY. CHANGING the number of VIBRATIONS PER second changes the pitch. ... Each fork is stamped with the note it produces (e.g. A) and its frequency in Hertz (e.g. 440 Hz). Shorter prongs produce higher pitch (frequency) SOUNDS than longer prongs.

ve:G = GM / R²Solution:Suppose mass of an object placed on the surface of celestial BODY = m mass of celestial body = Mit's radius (Distance between object and centre of celestial body) = R and, universal gravitational CONSTANT = G then, ➡ Weight of the body = Gravitational force exerted by celestial body on the object [So, Using Newton's second law and Newton's universal law of gravitation]➡ mg = GMm/R²➡ mg/m = GM / R²➡ g = GM / R²That is the expression for acceleration due to gravity on any planet or celestial body with mass M and radius R.

There are DIFFERENT types of specialized HYDROMETERS named after their uses:Lactometer for milk.Alcoholometer for WINES and alcoholsSaccharometer for sugar.A BAROMETER for tanning LIQUIDS in leather-making.Urinometer for urine analysis.Acidometer for acids.Batter hydrometer for lead-acid battery.Salinometer for liquids with salt content.Thermohydrometer for fuel oils like petroleum.Explanation:Hope it helps you..

The ANSWER is BPLEASE THANK my answer

Alpha diversity refers to ONE species, whereas BETA diversity COMPARES between different communities. GAMMA diversity sums up both the alpha and beta diversity of a region. Complete step by step ANSWER: The biodiversity present within the community is said to be alpha diversity

tion:STANDARDS which are used to MEASURE the fundamental quantities are called as fundamental units which are LENGTH, mass, time, temperature, current, luminous INTENSITY, quantity of matter. Hence, magnetic field is not a fundamental quantity.

Every yearThe International Day for Biological DIVERSITY is a United Nations–sanctioned international day for the promotion of biodiversity ISSUES. It is currently held on May 22. The International Day for Biological Diversity falls WITHIN the scope of the UN Post-2015 Development Agenda's Sustainable Development Goals.Hope it's HELPFUL to you

here is your ansExplanation:36 BIODIVERSITY hotspotsAs we have learned, a region with a large number of species is considered to be biodiverse. There are 36 biodiversity hotspots on our PLANET, and these areas are DAZZLING, UNIQUE, and full of life.GOOD QUESTION BRO

;)Explanation:edge effectThe presence of diversity at the junction of terretories of TWO different habitats is known as edge effect. In other words, the POTENTIAL for the ecotone to act as HABITAT for SPECIES found in neither major community is called edge effect

Work done on an object along a given direction of MOTION is EQUAL to the force TIMES the displacement times the COSINE of the ANGLE.

One joule One joule is defined as the AMOUNT of work done when a FORCE of one newton is exerted through a distance of one METER. In the English system of UNITS, where force is measured in pounds, work is measured in a unit CALLED the foot-pound (usually abbreviated ft-lb)Explanation:

tion:Plant SPECIES can also be ENDANGERED. Seed BANKS are a conservation measure for plants. Seeds are carefully stored so that NEW plants may be grown in the future. Seed banks are an example of a gene bank .
