CENTIGRADE is not a FUNDAMENTAL UNIT

Answer:

On the surface of the Earth, the escape velocity is about 11.2 km/s, which is approximately 33 times the speed of sound (Mach 33) and SEVERAL times the muzzle velocity of a RIFLE bullet (up to 1.7 km/s). ... An object has REACHED escape velocity when the specific ORBITAL energy is greater or equal to zero.

ANSWER:

Convex mirror is a type of mirror that will shrink every object. So it does not MAKE sense if the object is MAGNIFIED five times. If, however, it is convex LENS, then we can use the lens formula:

1u+1v=1F

If it is magnified 5 times, v=5u, which is derived from similar triangles, not directly from the QUESTION, and thus 1u+15u=1F

So, 1+15=uF

u=6F5

EXPLANATION:

DRIVER can turn a steering wheel by applying a force on its rim. We utilise the turning effect of forces (moments) on a daily basis, for EXAMPLE when we use devices such as LEVERS. HOWEVER, in some circumstances we need to prevent the turning effect of forces by balancing them with an opposing moment.

ANSWER:

total TIME =1hr. 15min.

average Speed=48kh/hr

Explanation:

time T1 to TRAVEL first 30km=distance/time

=30/60=1/2hr

time T2 to travel NEXT 30km=

30/40= 3/4hr

total time of journey=T1+T2=

(1/2)+(3/4)= 5/4hr.

that is = 1hr.15min.

average speed=total distance/total time

=60/(5/4)=48km/hr

CsCl has a BASIC CUBIC STRUCTURE that CONSISTS of an infinite chain of IONS. ... Nacl - NaCl has a cubic unit cell. It is the best thought of as a face centered cubic array of anions with an interpenetrating FCC cation lattice . The cell looks the same whether you starts with anions or cations on the corners .

The chemical formula of limestone is solid CALCIUM CARBONATE...

One molecule of limestone CONTAINS one Calcium atom, one Carbon atom and three Oxygen atoms...

SINCE the total number of atoms in one molecule of limestone is 5,

Hence, the ATOMICITY of limestone is 5

ANSWER:

when t=0

then, SPEED is 0

when t=2

then, speed is 44

Answer:

A current of 1ma flows through a copper WIRE, how many electron will pass a GIVEN point in one SECOND? 1 COULOMB = 6.24 x 10^18 electrons .

Answer:

It WOULD be attracted by it because they have opposite CHARGES. If they didn't attract each other, we wouldn't have atoms because there would be nothing to hold the electrons to the atoms. They would repel each other.

Van de GRAFF Generator.

Theory :

Robert van de Graaff build a generator in 1931 that produce highly energetic charge particles.

Such particles are useful in treatment of cancer.

Principle :

It based on the phenomenon of corona DISCHARGE and that the charge given to a hollow CONDUCTOR get transfer to the outer surface to be distributed uniformly.

Use :

It is a device which used for generation high ELECTRIC potential of an ORDER 10 million volt. And such electric potential are needed to accelerating charge particles to very high speeds.

Thank you

Concept of RELATIVE velocity (for 1-D): If TWO OBJECTS are moving along the same straight line and we are observing the motion from the frame of one object. Then for the relative velocity, it will be subtracted for velocities in same DIRECTION and ADDED for velocities in opposite directions. (Remember: add or subtract them with proper sign conventions).

Explanation:

so it is 9R

Answer:

4.8

Explanation:

On the left SIDE, the resistors are in series i.e. the resistance will be added

6Ω + 2Ω = 8Ω

this series with resistance 8Ω will be then parallel to the middle resistance

hence  we get resistance of 4Ω and the LAST resistance series is in series hence we get 16Ωnow this 16Ω resistor and 4Ω resistor is in parallel hence by the formula used for parallel serie

i.e R1 X R2 /R1 +R2

16 x 4 /16+4

= 4.8

=> ( root 3 - 1) / 2 root (2)

ANSWER:

⭕ Lenz's law states that the INDUCED current will APPEAR in such a direction that it opposes the cause which produce it.

Lenz's Law gives us the direction of induced current in a circuit.

Example :- When the magnet is moved towards the loop , a current is induced in the loop.

⭕ Eddy's currents are the current which induces when there is a CHANGE in magnetic flux of the conductor.

Hey BRAINLY user

Here is your answer

State law of mass action :

The RATE of REACTION is directly proportional to the product of ACTIVE masses or molar CONCENTRATION of reactants

Answer:

Resistance = प्रतिरोध

RESISTIVITY = प्रतिरोधकता

Resistance, R = rho L/A

L = 15 m

Area, A = 6 × 10^-7 m^2

R = 5 ohm

5 = Rho 15 × 10^7/ 6

Rho = 30 × 10^ (- 7) /15

Rho = 2 × 10^-7 ohm.

Answer:

Hi mate.

NEWTON's THIRD law of motion is naturally applied to collisions between two objects. In a COLLISION between two objects , both objects experience forces that are equal in MAGNITUDE and opposite in direction. Such forces often cause one object to GAIN momentum and other object to lose momentum.
