Least count of a screw gauge is the minimum length that we can measure using a screw gauge. We can measure the least count of the screw gauge by measuring the pitch of the screw gauge and the number of divisions on the circular scale.

Answer:

The minimum amount of value or number which can be measured by a screw gauge is called its least count or L.C

Explanation:

Answer:

3 seconds

Explanation:

  initial velocity = 0ms

  final velocity = 24ms

  time(1) = 3s

  acceleration = ?

  time (2) =?

 solution:-

                          to find acceleration,

                 a =( vf - vi ) / t

                    = 24-0 /3

                    = 24/ 3

                 a= 8ms^-2

                          To find time(2)

                 t= (vf - vi )/ a

                   = 24- 0 / 8

                   = 24/ 8

                   = 3seconds

Answer: If you are adding heat to a sample at a constant rate , you plot the temperature against time.

The speed of the waves will be 100 cm/s. The speed of a wave is the product of the frequency and wavelength.

When an object vibrates, a pressure wave is created, which produces sound. The particles in the surrounding medium (air, water, or solid) vibrate as a result of the pressure wave.

For one node distance is [tex]\lambda[/tex]

The distance between 4 nodes;

[tex]=\rm \lambda+ \frac{\lambda}{2} \\\\ = \frac{3 \lambda}{2} \\\\[/tex]

The distance between 4 nodes = 15.0 cm.

[tex]\frac{3\lambda}{2} = 15 \times 10^{-2} \\\\ \lambda= \frac{2 \times 15 \times 10^{-2}}{3} \\\\\ \lambda= 10 \times 10^{-2}[/tex]

The given frequency of the source is;

f = 10 Hz

The speed of wave is found as;

[tex]\rm v = f \lambda \\\\ v= 10 \times 10^{-2} \\\\ v=1 \ m \\\\\ v = 10^2 \ cm/sec[/tex]

Hence,  the speed of the waves will be 100 cm/s

Answer:

Explanation:

mass of the water and power of the pump

mass of the water and power of the pump determines the height to which a force pump can lift water​.

To operate the forced pump, the user pushes a lever or handle on the ground. When the handle is pushed, the downhole cylindrical piston is pushed down into the well. As the piston passes through the water, it is pushed around the sides of the piston.

In addition to the fuel, the suction pump also supplies pressure. This allows the injector to pressurize the fuel more efficiently and prevent the engine from "starving". Without a suction pump, the injection pump would have to spend more time drawing fuel from the tank itself and pressurizing it before supplying it to the engine.

The value of the resistance of the series RLC circuit attached to a 120 V/60 Hz power line is 35.57 ohms.

The power factor of RLC series circuit is determined from the ratio of resistance to the total impedance of the circuit.

Pf = R/Z

0.83 = R/Z

where;

Z = V/I

0.83 = R/(V / I)

0.83 = (RI) / (V)

RI = 0.83V

R = 0.83V/I

R = (0.83 x 120) / (2.8)

R = 35.57 ohms

Answer:

Sine they are at right angles to each other, therefore “theta”= 90°. Using our cosine rule to look for our resultant force.

Explanation:

A^2=B^2+C^2 - 2BC COSthetha

A=resultant force; B=3N; C=4N; COS90=0.

A^2=3^2+4^2 - 2×3×4×0

A^2=9+16–0

A^2=25

A=√25

A=5N.

Answer:

The answer would be 25kg.

Explanation:

Because the force is 50 N and the acceleration is 2 meters per second squared and the Newton's Law Triangle is F = m x a or Force = Mass x Acceleration so we have to solve the equation 50 divided by 2 or 50/2 which results in 25kg.

Answer:

(a) 10.20 s (nearest hundredth)

(b) 127.55 m (nearest hundredth)

(c) 883.70 m (nearest hundredth)

Explanation:

Part (a)

At the end of the projectile's flight, its vertical displacement will be zero.

Resolving vertically, taking up as positive:

[tex]s=0\quad u=100 \sin30^{\circ} \quad v=v, \quad a=-9.8, \quad t=t[/tex]

[tex]\begin{aligned}\textsf{Using }\:s & =ut+\dfrac12at^2:\\ 0 & =100 \sin 30^{\circ}t+\dfrac12(-9.8)t^2\\ 0 & = 50t-4.9t^2\\ 4.9t^2 & = 50t\\ 4.9t & = 50\\ t & = \dfrac{50}{4.9}\\ t & = 10.20\:\sf s\:(nearest\:hundredth)\end{aligned}[/tex]

Part (b)

At the maximum height, vertical velocity will be zero.

Resolving vertically, taking up as positive:

[tex]s=0\quad u=100 \sin30^{\circ} \quad v=0, \quad a=-9.8, \quad t=t[/tex]

[tex]\begin{aligned}\textsf{Using }\:v^2 & = u^2+2as :\\ 0^2 & = (100 \sin 30^{\circ})^2+2(-9.8)s\\ 0 & = 2500-19.6s\\ 19.6s & = 2500\\ s & = \dfrac{2500}{19.6}\\ s & = 127.55\: \sf m\:(nearest\:hundredth) \end{aligned}[/tex]

Part (c)

The horizontal velocity of a projectile is always constant, so u = v.

The horizontal component of acceleration is zero.

Resolving horizontally, taking right as positive (and using the value for t we found in part a):

[tex]s=s\quad u=100 \cos30^{\circ} \quad v=100 \cos30^{\circ} , \quad a=0, \quad t=\dfrac{50}{4.9}[/tex]

[tex]\begin{aligned}\textsf{Using }\:s & =ut+\dfrac12at^2 : \\ s & =(100 \cos 30^{\circ})\left(\dfrac{50}{4.9}\right)+\dfrac12(0)\left(\dfrac{50}{4.9}\right)^2\\ s & =50\sqrt{3}\left(\dfrac{50}{4.9}\right)+0\\ s & =883.70\: \sf m\:(nearest\:hundredth)\end{aligned}[/tex]

Hi there!

Recall that the amplitude of an oscillating system occurs at a point of maximum potential energy.

For a spring system, potential energy is given as:
[tex]U = \frac{1}{2}kx^2[/tex]

U = Potential Energy (J)

k = Spring constant (N/m)
x = amplitude (m)

We can rearrange the equation to solve for amplitude more easily.

[tex]U = \frac{1}{2}kx^2\\\\2U = kx^2\\\\x^2 = \frac{2U}{k}\\\\x = \sqrt{\frac{2U}{k}}[/tex]

If we double 'U':
[tex]x' = \sqrt{\frac{2(2U)}{k}} = \sqrt{2}*\sqrt{\frac{2U}{k}}\\\\x' = \sqrt{2} * x[/tex]

Thus, the new amplitude would be √2 times greater, so:

(a) The magnitude of force vector B at the given resultant force is 120 N.

(b) The direction of  force vector A is 142.46°

The resultant forces is calculated as follows;

Acosθ + Bcosθ = 0 --- (1)

Asinθ + Bsinθ = 150 ---- (2)

Acosθ + Bcos60 = 0    

-60 + Bsin60 = 0     (Acosθ = x-component of A = Ax)

Bcos60 = 60

B = 60/cos(60)

B = 120 N

Asinθ + Bsinθ = 150

Ay + Bsinθ = 150

Ay + 120sin60 = 150

Ay = 150 - 120sin60

Ay = 46.1 N

compressibility, pressure, buoyancy, viscosity, and surface tension are characteristic of a fluids.

Fluid is a material which can flow. gas and liquid is called as fluid. If a fluid is not compressible and it has zero viscosity it is considered an ideal fluid.

Fluids have no definite shape.

it has many characteristics,

Compressibility, different fluids have different compressibility, only gas is compressible, liquids are incompressible.  

Pressure - all flued have pressure associated with them, when a gas is enclosed in a box, gas molecule have kinetic energy which collides on the wall of the box and pressurize it. Flowing water have pressure.

buoyancy - when a small object is falling in the flued a force called buoyance force is acted upon it which opposes falling motion.  

Viscosity - it is relative motion between two adjacent layer, each liquid has different viscosity.    

surface tension - it is the force per unit tangential line on the region which acts as stretched membrane.
