What is Latent heat?Latent heat is energy that a body or thermodynamic system releases or absorbs during a constant-temperature process, typically a first-order phase transition. Latent energy and heat of transformation are other names for it.Latent heat can be thought of as energy that is provided or removed in a concealed form in order to alter a substance's state without altering its temperature. Latent heat of fusion and latent heat of vaporization, which are involved in phase shifts when a substance condenses or vaporizes at a particular temperature and pressure, are two examples. In contrast to latent heat, sensible heat is energy that is conveyed as heat and causes a change in a body's temperature.

a bullet of mass m1 is fired towards a block of mass m2 initially at rest at the edge of a frictionless table of height h as in the figure. the initial speed of the bullet is vi . consider two cases, a completely inelastic one and an elastic one,where the bullet bounces off the block.

Answers

The ratio of time of flight for inelastic collision to elastic collision is 1 : 2.

An inelastic collision is a type of collision in which the kinetic energy does not remain the same before and after the collision, while an elastic collision is a type of collision in which the kinetic energy remains the same before and after the collision.

initial kinetic energy = final kinetic energy(1/2)*m*u² = (1/2)*m*v²

mass of the bullet, = m₁

mass of the block, = m₂

initial velocity of the bullet, = u₁

initial velocity of the block, = u₂ = 0

final velocity of the block = v

When inelastic motion is considered:

final velocity of the b can be calculated by the formula,

m₁u₁ + m₂u₂ = v ( m₁ + m₂)

v = ( m₁u₁ + m₂u₂ ) / ( m₁ + m₂)

According to the equation of motion,

v = u + at

u = o

v = at ( a=g )

t = v/g

t = ( m₁u₁ + m₂u₂ ) / {g*( m₁ + m₂)}

When  elastic motion is considered:

final velocity will be given by ,

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

Since u₂ = 0

m₁u₁ = m₁v₁ + m₂v₂

the block undergoes unidirectional motion,

so u₁ + (-v₁) = u₂ + v₂

v₁ = u₁ - v₂

therefore, m₁u₁ = m₁(u₁ - v₂) + m₂v₂

v₂ = 2m₁u₁ / ( m₁ + m₂)

According to the equation of motion,

v = u + at

u = o

v = at ( a=g ) ( v=v₂) ( t=t₂)

t₂ = v₂/g

t₂ = 2m₁u₁ / g( m₁ + m₂)

Ratio of t₁ and t₂ is  ( m₁u₁ + m₂u₂ ) / {g*( m₁ + m₂)} / 2m₁u₁ / g( m₁ + m₂)

t₁ : t₂ = 1 : 2.

if the plane is flying horizontally and suddenly pulls upward, in which direction does the nose of the plane tend to move?

Answers

If the plane is flying horizontally and suddenly pulls upward, the nose of the plane tends to move upwards as the tail moves downwards.

A plane (formally an airplane) is a fixed-wing aircraft that is propelled forward by the thrust of a jet engine, propeller, or rocket engine.

All flight controls use the same basic lift principles as wings. When the pilot moves the controls, they produce lift of nose either up or down.

When the pilot pulls on the control column, the elevator moves up. This creates a wing-like curve on the surface that pulls the tail down. By moving the tail down, the nose of the aircraft rises.

When the pilot pushes forward on the controls, the elevator points down. The opposite happens and there is a lift that pulls the tail up. Pulling the tail up causes the nose of the plane to drop down.

The vector's magnitude is 5.4m/s²and direction is 56.30°.

Is a vector directional and has a magnitude?

We will talk about vectors and scalars in this section. Quantities called vectors have both a magnitude and a direction. The indication of a vehicle's motion serves as a practical example of a vector.

Given,

ax = 3.0 m/s², ay = -4.5 m/s²

a = [tex]\sqrt{a^{2} _{x} + a^{2} _{y} }[/tex]

a = [tex]\sqrt{3^{2} +-4.5^{2} }[/tex]

a = [tex]\sqrt{9+20.25}[/tex]

a = [tex]\sqrt{29.25}[/tex]

a = 5.4m/s².

A vector's direction can be established by

α = tan⁻¹ y/x

α = tan⁻¹-4.5 / 3.0

α = tan⁻¹(1.5)

α = 56.30°.

The angle that the vector makes with the horizontal axis, or the X-axis, determines the vector's direction. By counterclockwise rotating the vector's angle at its tail toward the east, one can determine the vector's direction.

The vector's direction is therefore 23.375° away from the X-axis, i.e., the vector Ax = 26 m/s², Ay = 10 m/s² points in the direction of the North-East.

a) Determine the speed of the coaster at position B. Friction and air resistance are negligible.

b) If the efficiency of the coaster is 55%, what would be the value of the coaster speed at point B?

Answers

The speed of the coaster at position B is 12mvB2. The value of the coaster speed at point B 3.016 m.

What is speed?

Speed is the rate in which something is traveling.

The speed of the coaster at position B can be determined using the work-energy theorem. According to the theorem, the work done by the gravitational force is equal to the change in kinetic energy. Therefore, the kinetic energy of the roller coaster at point B is equal to the potential energy at point A.

The potential energy at point A is equal to mghA, where m is the mass of the roller coaster, g is the acceleration due to gravity, and hA is the height of point A. Similarly, the kinetic energy at point B is equal to 12mvB2, where vB is the speed of the roller coaster at point B.

Therefore, the speed of the roller coaster at point B can be calculated as follows:

vB = √(2ghA/m) = √(2*9.8*30/m) = 5.48 m/s.

b) The efficiency of the roller coaster is 55%, so the actual speed of the roller coaster at point B would be 55% of the calculated speed. Therefore, the actual speed of the roller coaster at point B would be 5.48 * 0.55 = 3.016 m

A car travelling at 5.0 m/s starts to speed up. After 3.0 s its velocity has increased to 11 m/s. a) What is its acceleration? (Assume it to be uniform.) b) What distance does it travel while speeding up?​

Answers

initially, the car is traveling at 5.0 m/s.

so, we know acceleration for changing velocity is :

a = (v-v[tex]_{o}[/tex])/t ..........(i)

where v is the final velocity

v[tex]_{o}[/tex] is the initial velocity

t is the time taken to change velocity

Now, as per the question :

initial velocity, v[tex]_{o}[/tex]=5.0 m/s

final velocity, v =11 m/s

time taken, t = 3 s

putting the values in equation (i),

a = ( 11-5 )/3

a = 2 m/s²

What distance will a care cover while uniformly accelerating from 12m/s to26m/s in 14 seconds?

Answers

266 m distance will be covered by a car uniformly accelerating from 12m/s to 26m/s in 14 seconds.

Uniform acceleration: If a body is travelling by increasing its velocity in equal intervals of time then that body is said to be in uniform acceleration.

s=ut+1/2 at² where as s= distance , u = initial velocity, t= time

to calculate the uniform acceleration a=[tex]\frac{v-u}{t}[/tex] here v= final velocity u= initial velocity.

we have v=26ms and u=12m/s

a=[tex]\frac{26-12}{14}[/tex] = 1 a=m/s².

now substitute a =1 in formula s=ut+1/2 at²

we get s=12(14)+1/2(1)(14)²= 266m

A body's resistance to being in its condition of rest or uniform motion is known as inertia. Due to its inertia, Maya is also propelled into the air.Newton's second law of motion serves as an example. Force is directly proportional to mass and acceleration, to sum up this law. The second box accelerates more quickly because its mass is lower than that of the first box.Newton's third rule of motion serves as the clearest example of this. According to this concept, there is an equal and opposite reaction to every action. Air is pushed downward by the bird's wind as it flies.

Given that, L/D = 10.5

D = L/10.5 -----(3)

Placing (3) in (1), we have

T = L/10.5 + W sinθ

T = (W cosθ)/10.5 + W sinθ

cosθ + 10.5 sinθ = T/W * 10.5

cosθ + 10.5 sinθ = (2000/8000) * 10.5

cosθ + 10.5 sinθ = 2.625

Solving the above equation, we get θ = 8.97°

Thus, the maximum angle of climb is 8.97°.

Suppose youhave a guitar string playing frequency fo.a) To increase the frequency by 4 octave(s), to 16fo, by what factor would you have toincrease the tension?Tv/To= ?b) To increase the frequency by 4 octave(s), to 16 fo, by what factor would you have todecrease the length?

Answers

To increase the frequency by 4 octave(s), to 16fo, by a factor of 16 we have to increase the tension. To increase the frequency by 4 octave(s), to 16fo, by a factor of 1/16 we have to decrease the length.

Is the frequency doubled at the octave?

An octave is a logarithmic unit for ratios between frequencies in electronics, with one octave equal to a doubling of frequency. For instance, 80 Hz is the frequency one octave above 40 Hz. The phrase comes from the Western musical scale, in which an octave represents a frequency doubling.

Finding octaves between two frequencies: how do you do it?

You can get the number of octaves between two frequencies, such as the upper and lower bounds of a band of noise, by first determining their ratio, then calculating the log of it, and then dividing that by the log of 2.

What is an octave's straightforward definition?

A musical interval is called an octave. Both in terms of music and physics, an octave is defined as An octave is the distance in pitch between a note, such as C#, and the note that follows it with the same name but is either higher or lower.
