Answer:

Force is a type of vector quantity in nature. It is categorized as a vector quantity because it is defined by two things,

Explanation:

-its MAGNITUDE and its DIRECTION

It comes under common vector quantity like "displacement, velocity, acceleration and force", Whereas, scalar quantities include "distance, speed, ENERGY and work".

Since force incorporates magnitude and direction, that makes it a vector quantity.

It has the ability to cause an OBJECT with mass to CHANGE its velocity. It is therefore a vector quantity.

Explanation:

bcoz no of electrons is 1.6*1013 which is opposite to flow of CURRENT beta MARK brainliest

Explanation:

Speed is the rate of change of motion, i.e. DISTANCE moved by an OBJECT in a specified time IRRESPECTIVE of direction. Velocity is speed with RESPECT to direction. Speed is a scalar quantity while velocity is a VECTOR.

Answer:

MAY be option (3)1.5 .

answer may be WRONG. I am not SURE.

HEYA MATE !

VECTOR quantity REFERS to the one which is having both MAGNITUDE nd direction.

Scalar quantity refers to the one which is having only magnitude.

Answer:

45

because

the TWO vectors may be i and j

an the EITHER VECTOR is i+j

so,

ANGLE between the vectors is 45

Orbital velocity ::-- In gravitationally BOUND systems, the orbital speed of an astronomical body or OBJECT is the speed at which it ORBITS around EITHER the barycenter or, if the object is much LESS massive than the largest body in the system, its speed relative to that largest body.

ANSWER:

the ADVANTAGES of si system is that we get larger and the perfect units to measure.

LONGER handle for water pump is preferred because, longer the handle less will be the force required.

This FOLLOWS the principle of moment of force, which is the product of force and the perpendicular DISTANCE of line of action of force from the axis of rotation

Hence, more the LENGTH of the handle less will be the effort required

Explanation:

Zero ERROR:

If the POINTER of the ammeter or voltmeter is exactly at zero, when it is not connected to the CIRCUIT, then the instrument has zero error. If the pointer is above the zero mark, the the zero error is negative. The NUMBER of divisions it is above the zero mark are to be subtracted from the READING.

Distance can only becomes ZERO

iff

the body is at the rest.

As distance is the ACTUAL path COVERED by THR body so,

the distance can only become zero if the body doesn't change its position with respect to time.

Answer:

K2CRO4

Explanation:

MOLAR MASS of K2CrO4 is 194.2 g/mol

Cr contributes 52 g

in K2CrO4 Cr = 26.8 %

Molar mass of K2CR2O7 is 294.2 g/mol

Cr contributes 2 atoms or 104g

in K2Cr2O7 Cr = 35.35 %

when you do the CALCULATION correctly you can see that the dichromate has considerably more percentage of Chromium

Answer:

1)A supercritical steam GENERATOR is a type of boiler that operates at supercritical pressure, frequently used in the production of electric pow

2)We MIGHT want to know what this is, its going to affect your electricity rates. Ultra supercritical (USC) steam generation is a derivation on the definitions of the temperature and pressure at which water vapor and liquid water are indistinguishable, aka the “Critical Point.” At that critical point of water some 705 degrees F/3208 psi, the bubbles of boiling disappears and the adding of heat or pressure to the BASIC water pushes a transition from water like to steam like characteristics.

3)A supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power. In contrast to a subcritical boiler in which bubbles can form, a supercritical steam generator operates at pressures above the critical pressure – 3,200 psi or 22 MPa.

ANSWER:

Force can also be called the CHANGE in momentum. BASED on all of this ,it is CLEAR that rate of change of momentum= mass× acceleration.This hold true when there is no EXTERNAL force acting on the system.

Electromotive force is the characteristic of any energy source capable of driving electric CHARGE around a circuit. It is abbreviated E in the international metric system but also, popularly, as emf. Despite its name, electromotive force is not actually a force.

Electromotive Force and Internal Resistance. The electromotive force (e) or e.m.f. is the energy provided by a cell or battery per coulomb of charge PASSING through it, it is MEASURED in volts (V). It is equal to the potential difference across the TERMINALS of the cell when no CURRENT is flowing.

1. Electromotive force, also called emf[1] (denoted and measured in volts), refers to voltage generated by a BATTERY or by the magnetic force according to Faraday's Law, which states that a time varying magnetic field will INDUCE an electric current.[2] Electromotive "force" is not considered a force, as force is measured ...

2. It's neutral. A wire/resistor cannot store CHARGE. Carrying current simply implies that charge carriers that already existed in the metal wire is in motion. And every charge particle that leaves the metal from one END, is compensated by ANOTHER entering the wire through the other end from the battery/voltage-source.

PS: Metals are rich in charge carriers. Existence of charge carriers is no reason to think that the material possess charge. A material possess charge, only if an imbalance in +,- charge carriers exist. In metals the +,- charge carriers are balanced, hence doesn't possess any charge in the first place.  And when its carrying current, the charge carriers that are lost from one end is replenished through the other end of the wire retaining the +,- charge balance.

Answer:

R/4 will be the RESISTANCE.

Explanation:

Given the resistance of the uniform wire is R.

If we cut it into two equal half

Then resistance of the ONE part of wire will be R/2 and that of another part will be R/2

Since these wires are connected in parallel

So, 1/Req = 1/ (R/2) + 1/(R/2)

⇒2/R + 2/R

⇒4/R

Now we have 1/Req = 4/R

So Req = R/4

Force

force is a word which we have all learnt. about when you push or pull some objects EXERT a force on it if you put a body force away from yourself when you pull a force to yourself.when you have you blocked in your hand you insert a large force when you hold a light block exert a small force.

force is an interaction between two objects forces affected by an object A on another object b.

the SI unit for measuring the force is CALLED Newton.

force is a vector quantity and if more than one force is acting on a particle we can find the resultant force USING the laws of vector addition.

If the ERROR in the MEASUREMENT of radius of a SPHERE => ∆r =2% and the error in the determination of volume of the sphere = 3∆r = 6%.

Explanation:

answer is 1600 m

the reason is that U have time =20s

acceleration=8m/s

and initial velocity=o and USING equation of motion

s=ut+1/2 att

on putting VALUES u will get s=1600

which is the required distance

=Most X-rays have a WAVELENGTH ranging from 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×1016 Hz to 3×1019 Hz) and energies in the range 100 eV to 100 keV. X-ray WAVELENGTHS are SHORTER than those of UV rays and typically longer than those of GAMMA rays.✔✔

Explanation:

Temperature COEFFICIENT of resistance (TCR) is the calculation of a relative change of resistance per degree of temperature change. It is MEASURED in PPM/°C (1 ppm = 0.0001%) and is defined as: TCR = (R2– R1)/ R1 (T2– T1).
