But the Archimedes principle states that the buoyant FORCE is the weight of the fluid DISPLACED. So, for a floating OBJECT on a liquid, the weight of the displaced liquid is the weight of the object. Thus, only in the special case of floating does the buoyant force ACTING on an object EQUAL the object's weight.

tion:Effects of REFRACTION of lightAn object appears to be raised when paced under water. POOL of water appears less deep than it actually is. If a LEMON is kept in a glass of water it appears to be BIGGER when VIEWED from the sides of glass. It is due to refraction of light that stars appear to twinkle at night.

Calculate the DISTANCE at which an object should be placed infront of a CONCAVE lens of focal length 30 cm to obtain an image of half of its size.f1 = 25 cm = 0.25 mp1 = 1/f1 = 1/0.25 = 4Df2 = -10 cm = -0.1mp2 = 1/f2 = 1/-0.1 = -10D(a) Power of the COMBINATION:P = p1 + p2= 4D + (-10D)= - 6 D(b) Focal length of the combination:F = 1/P = 1/-6 = -0.1666m = -16.66cm(c) The combination has negative focal length, so it is diverging.

Image result for Define torque.Explain with two EXAMPLES from daily life. Another common example of torque in everyday life is HINGED doors. When you open a door, the torque applied in the situation ALLOWS it to move around the rotational axis. Here, the PIVOT point is the hinges, and if you apply force near the hinges, you are likely to face difficulty in OPENING it.Explanation:

They are the SIMPLEST mechanisms known that can use leverage (or MECHANICAL ADVANTAGE) to increase force. The simple machines are the inclined plane, lever, wedge, wheel and AXLE, pulley, and screw. Six simple machines for transforming energy into work.

Whenever we DESCRIBE an object’s motion, the first thing we TALK about is the POSITION of the object. Where is the object? It is some DISTANCE from a zero point (the point we call the origin) in a particular direction. EXPLANATION:

(a,0)=(12,0) Vertex :(h,k)=(0,0)Computing the DISTANCE P USING the general formula, we have:p=√(h−a)2+(y−0)2p=√(0−12)2+(0−0)2p=√(12)2p=12Here, we have:(y−k)2=4p(x−h)Substitute GIVEN values in the above formula and simplify it.(y−0)2=4⋅12(x−0)y2=2xThus, the equation of the PARABOLA is y2=2x.

When a 3 phase supply is given to the STATOR winding it sets up a rotating magnetic field in space. This rotating magnetic field has a speed which is known as the synchronous speed.This rotating magnetic field induces the voltage in rotor bars and hence short-circuit currents start flowing in the rotor bars. These rotor currents generate their self-magnetic field which will interact with the field of the stator. Now the rotor field will try to oppose its cause, and hence rotor starts following the rotating magnetic field.The MOMENT rotor catches the rotating magnetic field the rotor current drops to zero as there is no more relative motion between the rotating magnetic field and rotor. Hence, at that moment the rotor experiences zero tangential force hence the rotor decelerates for the moment.Squirrel Cage Induction MotorAfter DECELERATION of the rotor, the relative motion between the rotor and the rotating magnetic field reestablishes hence rotor current again being induced. So again, the tangential force for rotation of the rotor is restored, and THEREFORE again the rotor starts following rotating magnetic field, and in this way, the rotor maintains a constant speed which is just LESS than the speed of rotating magnetic field or synchronous speed.Slip is a measure of the difference between the speed of the rotating magnetic field and rotor speed. The frequency of the rotor current = slip × supply frequency

Mark me as BRAINLIEST Explanation:A computer is a machine that can be instructed to carry out SEQUENCES of arithmetic or LOGICAL operations automatically via computer programming. Modern computers have the ability to FOLLOW generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of TASKS.

It's acceleration is POSITIVE because the VELOCITY of the body is not constant DUE to change in DIRECTION of the MOTION of the body.

The nonrotating Voyagers had CAMERAS that TOOK vivid photos of the PLANETS and their moons. The simpler Pioneers could store only five COMMANDS in memory, and had to be CONSTANTLY commanded from Earth, while the Voyagers were programmable and so could adapt to their longer mission.

After that momentous EVENT, Voyager 1 is now adrift between the STARS. Light-years of essentially nothing between it and … well, nothing else. In about 300 years, the craft will reach the inner boundary of the Oort Cloud, the THIN, diffuse SHELL of frozen debris left over from the formation of the solar system.

Of the four spacecraft sent out to beyond the environs of the solar system in the 1970s, three of them -- Voyagers 1 and 2 and Pioneer 11 -- were all heading in the direction of the solar apex, i.e., the apparent direction of the Sun's travel in the Milky Way galaxy, and thus WOULD be expected to REACH the HELIOPAUSE ...Spacecraft Mass: 1,592 pounds (721.9 kilograms)Mission Design and Management: NASA / JPLLaunch Site: Cape Canaveral, Fla. / Launch COMPLEX 41Launch Vehicle: Titan IIIE-Centaur (TC-7 / Titan no. 23E-7 / Centaur D-1T)

mals and most microorganisms rely on the continual uptake of large amounts of organic compounds from their environment. These compounds are used to provide both the carbon SKELETONS for biosynthesis and the METABOLIC energy that drives cellular processes. It is believed that the first organisms on the PRIMITIVE Earth had access to an abundance of the organic compounds produced by geochemical processes, but that most of these original compounds were used up billions of years ago. Since that time, the vast majority of the organic materials required by LIVING cells have been produced by photosynthetic organisms, INCLUDING many types of photosynthetic bacteria.
