We know that, CROSS(vector) PRODUCT of two vectors is a third vector whose magnitude is GIVEN by the product of magnitude of given vectors MULTIPLIED by sin ratio of the smaller angle between them. In your case, given two vectors are the same, i.e., A and hence, they are EQUAL in magnitude and angle between them is 0°.

The triboelectric effect causes an electrostatic charge to build up on the FUR due to the CAT's motions. The electric field of the charges results in a slight attraction of the light plastic PIECES to the charged fur. The triboelectric effect is also the cause of static cling in clothes.

When the PENDULUM stops briefly at the top of its swing, the kinetic energy is zero, and all the energy of the system is in potential energy. When the pendulum swings back down, the potential energy is CONVERTED back into kinetic energy. ... The TRULY conserved quantity is the sum of kinetic, potential, and thermal energy.Explanation:please MARK as BRAINLIEST

tion:In parallel connection of RESISTORS there is same POTENTIAL difference at the ends of the resistors. Hence the VOLTAGE in the circuit is equal to V. LET I1, I2 and I3 be the currents flowing through R1, R2 and R3 resistors respectively. Hence, we can write I = I1 + I2 + I3. Hope it helps you. then mark me as a brainliest

It is said that the object is PLACED in front of the MIRROR at a distance of 10cm. THEREFORE, u=−10cm. The focal length of a CONVEX mirror is always positive. Therefore, f=15cm.Explanation:I HOPE IT'S HELPFUL TO

The ANSWER is (III) in the PIC .

In 1st picture it is SEEN that BODY has zero velocity at rest. While in 2nd GRAPH it is seen that it has some velocity at ORIGIN.

Statement : The M.I of a BODY about any axis is EQUAL to the sum of the M.I of the body about a PARALLEL axis passing through its C.G. and the plroduct of the MASS of the body and square of the DISTANCE b/w the two axes. This is called Steiner's theorem.

curved mirror is a mirror with a curved REFLECTING surface. The surface may be EITHER CONVEX or concave. Most curved mirrors have surfaces that are shaped like PART of a sphere, but other shapes are SOMETIMES used in optical devices.

We can measure the diameter of this circle using which we can calculate the area 'A'. If 'v' is the volume of one drop, then the volume of n DROPS of solution is 'nv'. Based on the assumption that the layer is one molecule THICK, we OBTAIN the VALUE of the size of the oleic acid molecule.

tion:PHYSICAL changes are caused by forces like motion, temperature, and PRESSURE. Hence The physical state of a matter depends UPON temperature and pressure. Change in temperature of WATER changes its state. Change in pressure of gas LIQUEFIES it.

The COMPUTATION of PERCENTAGE error INVOLVES the use of the absolute error, which is simply the difference between the observed and the TRUE VALUE. The absolute error is then divided by the true value, resulting in the relative error, which is multiplied by 100 to obtain the percentage error. mark me as brainliest.

General relativity, also known as the general theory of relativity, is the geometric theory of GRAVITATION published by ALBERT Einstein in 1915 and is the CURRENT description of gravitation in modern PHYSICS.

We can calculate the value of force USING Pascal's Law FORMULA. ... A piston of small cross-section A is used to exert a force F directly on the liquid. The pressure P =F/A is transmitted throughout the liquid to the larger cylinder attached with a larger piston of AREA B, which RESULTS in an upward force of P × B.

Cartridge fuses are cylindrical in shape and have contact points at each end. They are rated for circuits over 30 amps and typically 240 volts. There are two BASIC TYPES of cartridge fuses. Ferrule-type fuses are rated up to and INCLUDING 60 amps.Explanation:

ength and vitality REQUIRED for SUSTAINED physical or mental activit.power DERIVED from the utilization of physical or chemical resources, especially to provide light and heat or to work machines.In physics, energy is the quantitative property that must be transferred to a body or physical system to PERFORM work on the body, or to heat it. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not CREATED or destroyed.
