A wheel rotates at 36.0 rad/s, it takes approximately 0.17453 seconds for the wheel to complete one revolution, and the wheel completes approximately 45.84 revolutions in 8.00 seconds.

(a) To find out how long it takes for the wheel to complete one revolution, you need to divide the given angular velocity by the total angle in one revolution. The wheel rotates at 36.0 rad/s. One complete revolution is equal to 2π radians (approximately 6.28318 radians).

Step 1: Divide the angular velocity by the angle in one revolution.
Time = (Total angle) / (Angular velocity)
Time = (2π radians) / (36.0 rad/s)

Step 2: Calculate the time.
Time ≈ (6.28318 radians) / (36.0 rad/s) ≈ 0.17453 seconds

So, it takes approximately 0.17453 seconds for the wheel to complete one revolution.

(b) To find out how many revolutions the wheel completes in 8.00 seconds, you need to multiply the angular velocity by the time and then divide by the angle in one revolution.

Step 1: Multiply the angular velocity by the time.
Total angle = (Angular velocity) × (Time)
Total angle = (36.0 rad/s) × (8.00 s)

Step 2: Calculate the total angle.
Total angle = 288.0 radians

Step 3: Divide the total angle by the angle in one revolution.
Revolutions = (Total angle) / (2π radians)
Revolutions ≈ (288.0 radians) / (6.28318 radians)

Step 4: Calculate the number of revolutions.
Revolutions ≈ 45.84

So, the wheel completes approximately 45.84 revolutions in 8.00 seconds.

F = 20 N

m = 250 g = 0.25 Kg

a = ?

Using Newton's 2nd Law

a = F/m

a = 20/0.25

a = 80 m/s²

The acceleration of an object with a mass of 250 grams or 0.250 kg and force applied of 20N is 80m/s².

Acceleration is the rate of change of velocity of an object. Acceleration means the speed of the object is changing, but not always. When an object moves in a circular path at a constant speed rather than variable, it is still accelerating, because the direction of its velocity is changing. It is a vector quantity as it has both the magnitude and direction. The SI unit of acceleration is meter per second (m/s²).

According to the formula,

f = m × a

f = force,

m = mass of the body,

a = acceleration of the body

f = 20N

m = 250 grams = 0.250kg (1kg = 1000grams)

f = m × a

a = f/ m

a = 20N/ 0.250kg

a = 80m/s²

Explanation:

 Here  the answer = 0.0080 .

Based on stokes law,

 v = g * D^2 *(d p - d m) / (18 V)

v = terminal velocity

D =  diameter of particle

V  =  Viscosity

dp =  density of particle

dm =  density of medium.

Here density of ball = 1.42 gm/cc

By substituting,

v = 9.81 x 9.52 x 10^-3 ^2 (1420 - 1300) / 18 x 1.0

=5.92x10^-4

 v(t) =0 .99 x Vtrm

  =0 .99 x  0.0059

  = 0.00059 m/s

  v(t)/Vterm =1-e^(-t/r)

  0.99 = 1 - e ^ (-t / 9.52 x 10^-3)

  e ^ (-t / 9.52 x 10^-3) = 0.01

Taking log

 -t / 9.52 x 10^-3 = -4.6

  t = 0.0438 s

Then smaller ball

v = 9.81 x 2.38 x 10^-3 ^2 (1420 - 1300) / 18 x 1.0

= 0.000037 m/s

v(t) / Vterm = 1-e^(-t/r)

0.99 = 1 - e ^ (-t / 2.38 x 10^-3)

e ^ (-t / 2.38 x 10^-3) = 0.01

Taking log

-t / 2.38 x 10^-3 = -4.6

  t = 0.0109 s

Here Reynolds number is,

According to the uncertainty principle, it is impossible to measure both the position and the velocity of a particle at the same time.

The uncertainty principle is a concept from quantum mechanics, according to which the precise location and momentum of a particle cannot be measured simultaneously.

It is impossible to predict the future behavior of particles or systems with certainty. The uncertainty principle was proposed by German physicist Werner Heisenberg in 1927.

According to the uncertainty principle, measuring the momentum of a particle will disturb its position and measuring its position will disturb its momentum. This is because the act of measurement itself changes the state of the particle.

Explanation:

The maximum velocity with which an electron can eject out when 100 mm wavelength light falls on Cooper's surface is 1.52×10³ km/s.

The longest wavelength that can eject an electron from the copper surface is 243 nm = 243 × 10⁻⁹m.

Speed of light(c) = 3×10⁸ m/s

Plank's constant (h)= 6.626 ×10⁻³⁴ kgm²/s

So, the work function of the metal =

hc ÷ λ = (6.626×10⁻³⁴ × 3×10⁸) ÷ 243 ×10⁻⁹

hc ÷ λ = 8.18 × 10⁻¹⁹ J

When 100 mm wavelength light falls on the copper surface the energy of emitted electron will be;

The energy of 100 mm wavelength = work function of copper metal + energy of the ejected electron

hc/λ = work function + kinetic energy (electron)

6.626×10⁻³⁴ ×3×10⁸/100×10⁻⁹ = 8.18 × 10⁻¹⁹+ kinetic energy

19.87 × 10⁻¹⁹ = 8.18 × 10⁻¹⁹ + Kinetic energy

Kinetic energy (electron) = 19.87×10⁻¹⁹ - 8.18×10⁻¹⁹

Kinetic energy= 10.69 ×10⁻¹⁹ J

Now, the mass of electron= 9.1 ×10⁻³¹ kg

We know that

Kinetic energy = 1/2(mv²)

10.69×10⁻¹⁹ = 1/2(9.1×10⁻³¹ × v²)

V² = 2× 10.69 × 10⁻¹⁹ ÷ (9.1×10⁻³¹)

V² = 2.34 × 10¹² m/s

V = ✓ 2.34 ×10¹²

V = 1.52 ×10⁶ m/s

Since 1 m = 10⁻³ km

Hence, 1.52×10⁶ m/s = 1.52×10⁶×10⁻³ km/s

V = 1.52×10³ km/s

So, the maximum velocity with which an electron can eject out when 100 mm wavelength light falls on Cooper's surface is 1.52×10³ km/s.

As a result, the system's maximum spring potential energy U is given by: U = (2π^2MD^2)/P^2

Potential energy is the energy stored by an item as a result of its location relative to other objects, internal tensions, electric charge, or other reasons. Potential energy is stored energy that is affected by the relative location of various components in a system. When a spring is squeezed or extended, its potential energy increases. A steel ball has higher potential energy when lifted above ground than when it falls to Earth.

Here,

The maximum spring potential energy U can be calculated using the equation:

U = (1/2)kD^2

where k is the spring constant, which can be found from the period of oscillation using the equation:

k = (4π^2M)/P^2

Substituting the expression for k into the equation for U, we get:

U = (1/2)((4π^2M)/P^2) * D^2

To find the formula for the velocity at any time (t) considering air resistance, we can use Newton's second law of motion. The force acting on the body is the gravitational force minus the air resistance force.

The gravitational force is given by:

where m is the mass of the body and g is the gravitational constant.

The air resistance force is given by:

where k is the air resistance coefficient and v is the velocity of the body.

According to Newton's second law, the net force is equal to the mass times the acceleration (F = m * a). Therefore, we can write the equation of motion as:

Substituting the expressions for F_gravity and F_air, we have:

Dividing both sides of the equation by m, we get:

Since acceleration is the derivative of velocity with respect to time (a = dv/dt), we can rewrite the equation as a first-order ordinary differential equation:

To solve this differential equation, we can separate variables and integrate:

Integrating both sides:

where C is the constant of integration.

Taking the exponential of both sides:

Since the velocity cannot be negative, we can ignore the absolute value sign:

Now let's find the limit of this velocity formula as the air resistance coefficient (k) approaches 0:

lim(k→0) v(t) = e^(g - (0/m)) * t * e^C

The exponential term e^C represents the initial condition, which we'll denote as v_0.

Therefore, the limit of the velocity as k approaches 0 is:

Comparing this solution to the equation for velocity when there is no air resistance (k = 0), we can see that the only difference is the presence of the exponential term e^g * t_0. This term represents the effect of air resistance on the velocity, causing it to decrease over time.

The important fact mentioned in the context of the fundamental theorem of ODE and continuous dependence on parameters and initial conditions is that even small changes in the parameters or initial conditions can lead to significant changes in the solution. However, when considering a fixed, finite terminal time (t_0), the variation in the solution due to small changes in the parameters or initial conditions will also be small, as indicated by the continuous dependence on these factors.

When dealing with infinite time intervals or boundary conditions, the final result can vary greatly depending on the initial conditions or parameters. For example, a solution starting with a small positive initial condition may tend to positive infinity, while a solution starting with a small negative initial condition may tend to negative infinity.

Velocity is a vector quantity that indicates how fast an object is moving. The magnitude of this vector is called speed and is expressed in meters per second.
