If the radius of each of the plates is increased by a factor of root2 and their distance of separation decreased to half of its initial value, calculate the ratio of the capacitance in the two cases.

Answer»

4:1 Explanation:Initially,Let the radius be r and DISTANCE between the circular plates be d. Capacitance(C) = When radius is increased by factor √2 and distancs is DECREASED to 1/2. HENCE, Hence, C'/C = 4C/C = 4:1 Required RATIO of the capacitane in the TWO cases is 4 : 1.

38.

What is center of gravity in human body?

Answer»

The centre of gravity (COG) of the HUMAN body is a hypothetical POINT AROUND which the force of gravity appears to act. It is point at which the combined mass of the body appears to be concentrated. Because it is a hypothetical point, the COG need not lie within the PHYSICAL BOUNDS of an object or person.

39.

What is center of gravity in mechanics?

Answer»

The center of gravity is the point through which the FORCE of gravity acts on an OBJECT or SYSTEM. In most mechanics problems the GRAVITATIONAL field is assumed to be uniform. The center of gravity is then in EXACTLY the same position as the center of mass.

40.

Which planets have the least gravity?

Answer»

The gravity of Mars is a natural PHENOMENON, DUE to the law of gravity, or gravitation, by which all THINGS with mass around the planet Mars are brought towards it. It is WEAKER than Earth's gravity due to the planet's smaller mass.Orbits: SUN

41.

Is Gravity present on moon?

Answer»

The Moon's surface gravity is about 1/6th as powerful or about 1.6 METERS PER second per second. ... The Moon's surface gravity is weaker because it is far less massive than EARTH. A body's surface gravity is proportional to its mass, but INVERSELY proportional to the square of its radius.

42.

Why is gravity more at the poles?

Answer»

it is frequently stated that the value of the acceleration due to GRAVITY at the pole is larger than at the EQUATOR because the poles are closer to the center of the EARTH due to the earth's oblateness. ... The measured value is larger because the earth's density is not uniform but INCREASES toward the center.

43.

What is the force of gravity on each planet?

Answer» FACE gravityMercury0.377 gVenus0.905 gEarth1 G (midlatitudes)Moon0.165 7 g (AVERAGE)
44.

How is gravity calculated?

Answer»

We can do this quite simply by using Newton's equation: forcegravity = G × M × mseparation2 . Suppose: your MASS, m, is 60 kilogram; the mass of your COLLEAGUE, M, is 70 kg; your centre-to-centre separation, r, is 1 m; and G is 6.67 × 10 -11 newton square METRE kilogram-2.

45.

Does time cause gravity?

Answer»

Yes, time goes faster the farther away you are from the earth's surface compared to the time on the surface of the earth. ... Gravitational time dilation OCCURS because OBJECTS with a LOT of mass create a strong gravitational field. The gravitational field is really a CURVING of SPACE and time.

46.

Where is gravity the strongest?

Answer» GRAVITY is strongest at the EARTH's surface, and its WEAKEST at the Earth's CORE.
47.

What is gravity exactly?

Answer»

gravity, also called gravitation, in mechanics, the UNIVERSAL force of attraction acting between all MATTER. It is by far the weakest known force in NATURE and THUS plays no role in determining the internal PROPERTIES of everyday matter.

What will happen to the heat developed in a cricute if the resistance is decreased​

Answer»

Rt ,then increasing RESISTANCE means decreasing the heat produced. IMPLIES that the voltage V stays constant. So with V=IR if V stays constant and the resistance R increases then the CURRENT I decreases.
