Explanation: The Distance Formula itself is actually DERIVED from the Pythagorean Theorem which is a 2 + b 2 = c 2 {a^2} + {b^2} = {c^2} a2+b2=c2 where c is the longest side of a right TRIANGLE (ALSO KNOWN as the hypotenuse) and a and b are the other shorter sides (known as the legs of a right triangle).

Answer:

Explanation:

Current sensitivity does not depend upon resistance(R), WHEREAS voltage sensitivity does, as evident from their expressions. Current sensitivity can be increased by INCREASING the number of turns of the coil. However, this INCREASES the resistance of the coil also(R is proportional to length of conductor). Since voltage sensitivity decreases with increase in resistance of the coil, the EFFECT of increase in number of turns is nullified in the case of voltage sensitivity. Hence, there is no increase in voltage sensitivity.

Answer:

• If an electric oven , a toaster and a GEYSER with resistance 125 , 50 and 250 ohm respectively are connect in parallel to a 220 V
• Then the equivalent resistance of parallel combination is 1/Rt = 1/125 + 1/50 + 1/250
• 2+5+1/250

=> 8/250

=> Rt = 31.25 ohm

• Also if an electric iron takes as much as current the all
• So FIRSTLY we have to find the TOTAL current of the three => V = IR

=>220 = I × 31.25

=> I = 220/31.25

=> I = 7.04 ampere

• Resistance of electric iron => V = IR

=> 220 = 7.04×R

=> R = 220/7.04

=> R = 31.25 ohm

Answer:

Inertia is a property of matter that CAUSES it to resist changes in velocity (speed and/or direction). According to NEWTON's first law of MOTION, an object with a given velocity maintains that velocity unless acted on by an EXTERNAL force. ... The amount of inertia that an object possesses is PROPORTIONAL to its mass .

Torricelli law expresses that the speed of stream of liquid from a hole is equivalent to the speed that it would accomplish if falling UNRESERVEDLY for a separation equivalent to the tallness of the free surface of the fluid over the opening .

The water won't fall in a PARABOLA like a gun shot. The water won't go up and descend in light of the fact that this is an infringement of the protection of vitality as the work will be managed without the outer power to do chip AWAY at it.

The CONDITION of the speed is for the speed of the coming water independent of the introduction of the opening on the holder which is as an afterthought.

In any case, when the water is falling through the GAP which is in the base of the holder. the water will turn out with consistent speed. Since the speed of the water isn't subject to the water section.

Answer:

Newton's law of universal gravitation is USUALLY STATED that every particle attracts every other particle in the universe with a force which is directly PROPORTIONAL to the product of their masses and inversely proportional to the square of the distance between their CENTERS.

Answer:

Dynamic lift is the force that acts on a body by virtue of its motion through a fluid. ... For example, during the game of cricket, TENNIS, baseball or GOLF,

we have noticed that a spinning ball DEVIATES from its parabolic TRAJECTORY during its motion in the air.

Answer:

To derive :

2nd Equation of motion USING graphical methods.

s = ut + ½at²

Proof:

Lets CONSIDER a velocity-time graph as attached above.

Now we know that displacement is given by the area under the velocity time graph.

Let initial velocity be u , final velocity be v , acceleration be a , time be t and distance be s

Now, area under the curve:

∴ s = Area of the trapezium

=> s = ½ (SUM of parallel sides) × DIST. between them

=> s = ½ (u + v ) × t ......(1)

Now we know that :

v = u + at .....(from 1ST eq. of motion) ......(2)

So putting value of "v" in eq.(1)

∴ s = ½ { u + (u + at)} × t

=> s = ½ { 2u + at } × t

=> s = ut + ½at²

[Hence proved .]

Answer:

The apparent weight of a FLOATING object is zero. This effect is quite different from the ACCELERATING lift EXAMPLES. A floating or immersed object is not accelerating upwards or downwards, so there can be no net force. In fact, buoyancy provides a SUPPORTING force exactly as the GROUND does.

ANSWER:

MARK me as BRAINLIEST. .....

Answer:

potential DIFFERENCE ( v ) = R × I

POTENTIAL DIFFERENCE ACROSS AB=

RESISTANCE (R) = 5 OHMS

CURRENT (I) = 1 AMPERE

SO

V = 1×5

•) V= 5 VOLTS

NOW , ACROSS AC

RESISTANCE (R) = ??

CURRENT (I) = 1

now for TOTAL resistance =

by parallel law -

1/Rp = 1/R2 + 1/R3

1/Rp = 1/10 + 1/15

1/Rp =( 3 + 2)/ 30

Rp = 30 / 5 = 6 ohms ------------ eq 1

now by series law ( from eq 1 )

Rs = R1 + Rp

Rs = 5 + 6

Rs = 11 ohms -------------eq 2

now by eq 2

VOLTAGE ACROSS AC =

11 × 1 = 11 volts

B) now voltage across R2 AND R3

BY EQUATION 1

RESISTANCE= 5 OHMS

CURRENT = 1 AMPERE

HENCE

VOLTAGE = 5 × 1

= 5 volts

now

c) total resistance = 11 ohms ( from eq 2)

Answer:

if you CONSIDER this as the DIAGRAM then the answer would be Fcos60°=F/2 according to VECTORS

LET the MASS of the removed ARC be m. So the moment of inertia of the remaining portion should be,

The length of the arc should be,

since the arc is corresponding to a 90° or a (π/2) radian sector.

Since the ring is assumed to be uniform, the LINEAR density is the same EVERYWHERE. Thus,

Then,

Therefore,

ANSWER:

u = 36 ×1000/3600 = 10 m/s

V = 54×1000/3600 = 15 m/s

v = u + at

15 = 10 + a ×10

15-10 = a ×10

5 = a × 10

a = 2 m/ s ^2

ANSWER:

I HOPE this MAY HELP you

Answer:

Throughout the scientific world where measurements are MADE in SI UNITS, thermodynamic temperature is MEASURED in kelvins (symbol: K).

Answer:

Given:

Equation of SHM has been provided.

x = 5 cos[(2πt) + π/4]

To find:

ACCELERATION at t = 1.5 seconds.

Concept:

Acceleration is obtained by 2nd order Differentiation of the displacement function wrt time.

Calculation:

x = 5 cos[(2πt) + π/4]

∴ v = dx/dt

=> v = 5 × (-2π) sin[(2πt) + π/4]

=> v = (-10π) sin[(2πt) + π/4]

Now acc = dv/dt = d²x/dt²

=> acc. = (-10π)×(2π) cos[(2πt) + π/4]

=> acc. = (-20π²) cos[(2πt) + π/4]

Now putting VALUE of t = 1.5 secs.

we get :

∴ acc. = (-20π²) cos[{2π(3/2)} + π/4]

=> acc. = (-20π²) cos[3π + π/4]

=> acc. = (-20π²) cos[13π/4]

Value of cos(13π/4) = (-1/√2)

=> acc. = (-20π²) × (-1/√2)

=> acc. = (20√2π²)/2

=> acc. = 10√2 π²

=> acc. = 10 × 1.414 × π × π

=> acc. = 139.57728 m/s²

So final answer :
