For the least amount of work, the exerting a force angle from horizontal is 76 degree.

Fcosθ−μN=maFcos⁡θ−μN=ma

N+Fsinθ−mg=0N+Fsin⁡θ−mg=0

(Unless Fsin>mgFsin>mg)

The angle is measured from the horizontal, and N is the upward normal force to the surface.

Work is defined as force times distance in the direction of motion... or a shift in energy. You want the man to do the work... guess: whole work. So attempt to accelerate the box (madmad) and against friction (NdNd).

So, how about this:

Minimizing force reduces effort for the same distance. As a result, we want the vertical component of force to be equal to and opposite to the weight. Any higher, and there is extra work propelling the box upwards.

This entirely removes friction, leaving only madness.

The non-relativistic limit of your expression for Fermi energy (ef) is shown in the figure below please convey to that figure.

The Fermi energy is the energy difference between the highest and lowest occupied single-particle states in a quantum system of non-interacting fermions at absolute zero temperature. The lowest occupied state in a Fermi gas is supposed to have no kinetic energy, in contrast to the lowest occupied state in a metal, which is frequently thought to represent the bottom of the conduction band. The term "Fermi energy" is frequently used to refer to the Fermi level, a different but closely related concept (also called electrochemical potential). At least in the context of this article, the Fermi level and Fermi energy differ significantly from one another: The Fermi level is defined at any temperature, but the Fermi energy is only stated at absolute zero. The Fermi level is a total energy level made up of both kinetic energy and potential energy (often corresponding to a kinetic energy). Even in complex interacting systems in thermodynamic equilibrium, the Fermi level is well defined, while the Fermi energy can only be specified for non-interacting fermions.

The initial speed of the bullet should be 159.32 m/s.

Let the initial speed of the bullet be V.

Momentum will be conserved after bullet hits the block . If v₁ be the common velocity of bullet block system

6.00 x 10⁻³ x V + 0 = ( 6 x 10⁻³ + 1.2 ) v₁

= ( 6 + 1200 ) x 10⁻³ v₁

v₁ = (6 / 1206 )  x V

1 / 201 V

Now the moving bullet - block system faces friction force and ultimately they come to rest , so

Kinetic energy of bullet block system = work done by friction

Kinetic energy of bullet block system =

1/2 x ( 6 + 1200 ) x 10⁻³  x ( 1 / 201 V )²

work done by friction

= frictional force x displacement

μ mg x d ( μ is coefficient of friction of surface , m is mass of the bullet block system and d is displacement )

0.16 x ( 6 + 1200 ) x 10⁻³ x 9.8   x .2

1/2 x ( 6 + 1200 ) x 10⁻³  x ( 1 / 201 )² V ² =

V² = 25382.65

V = 159.32  ms⁻¹

The impulse of the friction force produced by the surface during the impact is disregarded when we apply conservation of momentum to the collision. This makes sense given that the force is far less than the forces that the bullet and block will exert on one another when they collide.

There are five phases namely, prophase, prometaphase, metaphase, anaphase and telophase. Final cell division after telophase, cytokinesis is regarded as the sixth phase of mitosis.

Mitosis begins with the prophase.

Chromosomes gather and are made visible. Centrosomes are the origin of spindle fibres.Nucleolus dissolves as nuclear envelope disintegrates.

Second stage of mitosis is known as prometaphase. Chromosomes continue to compact. Centrosomes travel in the direction of their opposite poles as mitotic spindle microtubules attach to kinetochores.

Third phase is metaphase. Each chromosome is in the centre.

The fourth stage is known as anaphase. Sister chromatids which were previously bound together by cohesin proteins, separate and are drawn in opposite directions.

The fifth stage is called telophase. The nuclear envelope material that surrounds each set of chromosomes decondenses as the chromosomes arrive at opposite poles.

The last stage of mitosis is known as cytokinesis. In animal cells, the daughter cells are divided by a cleavage furrow.

The speed of a tsunami depends on the depth of the water it is traveling through. The deeper the water; the faster the tsunami.

What is windspeed?

In meteorology, wind speed, also known as wind flow speed, is a fundamental atmospheric quantity brought on by air shifting from a state of high to low pressure, frequently as a result of temperature changes. Nowadays, an anemometer is frequently used to measure wind speed.

What is tsunami?

A tsunami is a set of waves brought on by a disturbance. Similar to the ripples created when a stone is thrown into a pond, a tsunami can be produced by a disturbance that moves the water vertically (a sudden drop or a sudden rise).

Three factors influence the formation

Windspeed;

Length of time the wind has blown over a given area; and

Distance of open water that the wind has blown over (called fetch).

The speed of a tsunami depends on the depth of the water it is traveling through. The deeper the water; the faster the tsunami. As the water depth decreases, the tsunami slows. The tsunami's energy flux, which is dependent on both its wave speed and wave height, remains nearly constant.

where v is the speed

f is the frequency

From the question

v = 12 m/s

f = 3 Hz

We have;

[tex] \lambda = \frac{12}{3} = 4 \\ [/tex]

We have the final answer as

Given

coefficient of kinetic Friction μ(k) = 0.1

Initial speed u = 3.6

Friction is present so it tries to stop to the object and stops it completely after moving certain displacement let say s

maximum deceleration provided by friction is

a(max) = μ(k) * g

           = 0.1 * 3.6

using equation of motion

v² - u² = 2as

where,

v = final velocity

u = initial velocity

Lifted to the height, R = 15.43 m

Gravitational potential energy at the height R can be calculated as:

What is angular velocity?

The rotation rate of an object, or how quickly it revolves or rotates in relation to another point, is measured vectorially as angular velocity. Angular velocity is simply the rate of rotation or revolving around an axis of an object.

What is magnitude?

Magnitude serves as the common denominator for both vector and scalar quantities. Their definition states that scalar quantities are those that have only magnitude.

Using the second relationship in v = r, vr = v r, and knowing v and r, we can get the angular velocity. To calculate the angular velocity, we will use the formula = vr. = v r.

If an object's radius is r, its linear speed is v, and its angular velocity is measured in radians per second, then v = r.
