Answer:

DC CURRENT to the dry cell and to the POWER house GENERATOR it is AC current

Answer:

5

Explanation:

V1 = 3i + 4J + k

v2 = i - J - k

v1 + v2 = 3i + 4j + k + i - j - k

= 4i + 3j

|v1 + v2| = √(4² + 3²)

= √(25)

= 5

FUNDAMENTAL unit :

A fundamental unit is that which is independent of any other unit or which can neither be changed nor can be related to any other fundamental unit.

Derived unit :

DERIVED unit are those which depend on the fundamental units or which can be EXPRESSED in terms of the fundamental units.

ANSWER:

STAR a

Explanation:

BEACUSE that star is not NEAR

slope of inclined plane , tanθ = 2/25

so, sinθ = 2/√(25² + 2²) = 2/√629

now, weight of car along inclined plane, F = mgsinθ

here, m = 1000kg, g = 10m/s² and sinθ = 2/√(629)

so, F = 1000 × 10 × 2/√(629)

≈ 797.452 N

VELOCITY of car along plane , v = 18km/h

= 18 × 5/18 = 5m/s

so, power of its ENGINE = weight of car along plane × velocity of car along plane.

= F × v

= 797.452 × 5 W

= 3,987.26 W = 3.98726 kW ≈ 4 kW

hence, power of car engine = 4kW

Answer:

It depends on WHETHER the VELOCITY is increasing or decreasing

Explanation:

If velocity is increasing and wavelength is kept same the frequency will INCREASE as more number of waves will pass through a given POINT in a second and vice versa if velocity is decreasing

requirements for good unit

1) A good unit should be correct. The basic REQUIREMENT of unit is to measure correct parameter of different physical quantities. Thus, it should be correct.

2) A good unit should be clear. The units of measurement should be clear, precise and and simple.

3) A good unit should be TESTABLE. The units should be testable because all the physical concept are based on experiments.

4) A good unit should be FEASIBLE. The good unit should be practically and easily available.

ANSWER:

19.6%

Explanation:

The apparent weight of the man in standing elevator, W=mg,

W=60(10)=600N

Now if the elevator is accelerating upwards then the apparent weight of the man, W'=m(g+a)

W'=m(10+1.96)

W'=60(11.96)=717.6

RELATIVE CHANGE in apparent weight=(W'-W)÷W

(717.6-600)÷600=0.196

PERCENTAGE relative change=

Relative change×100

0.196×100=19.6

ANSWER:

Explanation:

Solution :-

We know,

F = GM₁m₂/r²

Let us take m₁ = 6 × 10²⁴ kg

m₂ = 2 × 10³⁰ kg

r = 1.5 × 10¹¹ m

Substituting the VALUE, we get

F = 6.67 × 10⁻¹¹ × 6 × 10²⁴ × 2 × 10³⁰/(1.5 × 10¹¹)²

= 3.6 × 10²² N

Thus, the gravitational force of attraction between the earth and the SUN is very large.

Additional Information :-

MASS of the earth = 6 × 10²⁴ kg

Mass of the sun = 2 × 10³⁰ kg

Distance between the sun and the earth = 1.5 × 10¹¹ m

G = 6.67 × 10⁻¹¹ Nm² kg⁻²

Explanation:

Displacement is defined as the SHORTEST  PATH traveled by a BODY and distance is the actual path length traveled by the body.

Displacement can be equal to the distance but it can never be lesser than it because if it was then it cant the defined as the shortest path anymore.

2) 6.25x10^15

Explanation:

1ma= 1000 x 1 A

=1000 A

When 1000 COULOMB charge flow through a wire in 1 second then the current through the wire is 1000 AMPERE.

I=Q/t

1 Ampere = 1 Coulomb /1 Second

Charge on 1 ELECTRON = 1.6 x 10^-19 Coulomb

By unitary method,

If 1.6 x 10^-19 Coulomb / Second (Ampere) = Current by 1 electron

then, 1( Coulomb / Second) or (Ampere) = 1000 / (1.6 x 10^-19) electrons

i.e, 6.25 x 10^15 electrons.

Friction is the resistance to motion of ONE object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. INSTEAD, scientists BELIEVE it is the RESULT of the electromagnetic attraction between charged particles in two touching surfaces

ANSWER:

he attractive force of gravity is proportional to the mass of the two

objects in question and to the square of DISTANCE.

Mass of the sun: about 2 x 10^30 kg

Sun-moon distance: about 150,000,000 km

The sun's gravitational PULL on the moon is proportional to 2 x 10^30
