What does gravitational force depend on?
Gravitational force depends on mass and distance.
Therefore, the formula for calculating gravitational force among two objects with a given distance: G [(mass 1) (mass 2)]/distance squared. G is universal gravitational constant: 6.67x10 raised to -11 power.
A FORCE OF 10I-3J+6K NEWTON ACTS ON A BODY OF 5KG AND IT DISPLACESFROM 6I+5J-3KMETRE TO 10I-2J+7K METRE. THE WORK DONE IS A)100J B)O C)121J D)NONE
A long, straight, current-carrying wire carries a current from west to east. A compass is held above the wire. a. Which direction does the north pole of the compass point? S
Beat period : The time interval among two successive beats is called as beat period. Beat frequency : The number of beats given per second is called as beat frequency.
a) It is a sort of disturbance which goes by a medium. b) Material phase is necessary for the propagation of mechanical waves. c) When a wave motion goes by a phase, molecule
according to the first law of thermodynamics , obtain the relationship between specific hears of gases
Q. In the given circuit, calculate the potential differences across each resistor Solution : i) R s = R 1 + R 2 + R 3 = 10Ω ii) Current in circuit I = V/R s
Discharging: The cell is connected across some load during discharging. As the direction of current by the cell is reversed during discharging the negative ions go in the directio
Moment of Inertia of Rigid Bodies : For a continuous mass distribution like found in a hard object, we remove the summation of Eq. (ii) by an integral. If the object is separated i
Determine the inductance of a solenoid of 2000 turns round uniformly over a length of 50 cm on a cylindrical paper tube 4 cm in diameter. The medium is air.
Wires A as well as wire B are both made out of copper. Wire B is double as long as wire A. The diameter of wire B is doubles that of wire A. Answer: Resistivity is a charac
