Answer: Rotational kinetic energy is not a vector quantity

Explanation:

Vector A volume that requires both magnitude and direction to be fully defined is called a vector.

Kinetic Energy It's defined as the energy held by a body when it's in stir,i.e haste isn't 0. When haste is 0, Kinetic Energy is basically 0.

Kinetic Energy is given by

K = 1 2 m v 2

where m = mass, v = haste.

Mass is a scalar volume and the haste which is a vector is squared which makes it a scalar volume as well. thus, Kinetic Energy is a scalar.

While much of the mass of our Galaxy lies within the bright spiral arms, the majority of the mass actually lies outside the luminous part of the Milky Way Galaxy.So the correct option is c.

The Milky Way Galaxy is a vast and expansive collection of stars, gas and dust that spans the universe. It is estimated to contain between 200 and 400 billion stars, making it one of the largest galaxies in the universe. The Milky Way is a spiral galaxy, meaning that it is composed of a central bulge surrounded by four main spiral arms. The luminous part of the Milky Way Galaxy, which is visible from Earth, lies within the spiral arms.

However, the majority of the mass of our Galaxy does not lie within the luminous part of the Milky Way Galaxy. Instead, much of the mass of the Milky Way lies outside the visible part of our Galaxy. This mass is found in the form of dark matter, which is an invisible form of matter that does not emit any light. Dark matter makes up around 85 percent of all the matter in the Universe and is believed to be responsible for the structure and evolution of galaxies.

The rest of the mass of our Galaxy is located within the bulge at the center of the Milky Way, as well as between Earth and the Galactic center. This mass is made up of stars, gas, dust and other forms of matter. While much of the mass of our Galaxy is invisible, it is still an important component of the Milky Way. Without this mass, the structure and evolution of the Milky Way would be drastically different.

Elasticity theory is concerned with the relationship between forces applied to an item and the subsequent deformations.

In practice, analyzing a material's elastic behavior is reduced to studying basic deformations and determining the appropriate elastic constants. Our bodily tissues are pliable. This mechanical feature is particularly significant in the lungs, skin, and arteries, because aging produces emphysema, loose skin, and arteriosclerosis. Elastic fibers are extracellular matrix fibers that resemble rubber and are responsible for tissue elasticity. Elasticity refers to an object's or material's capacity to return to its original shape after being stretched or crushed.

What is intensity?

Intensity is the amount of energy a wave carries over a surface of a particular area in a unit of time, and it is the same as the energy density times the wave speed. The most popular unit of measurement is watts per square meter. The strength and size of a wave affect its frequency.

What is earth quake ?

An earthquake is the abrupt release of energy from the earth's crust that causes the earth's surface to shake. Seismic waves, also called S waves, are consequently produced.

I = 11000 J/(m^2 s)

r = 35 km

t = 11 s

a) from the given data

Energy produced by earth quake in 11 seconds

E = I*A*time

= I*4*pi*r^2*t

= 11000*4*pi*(35*10^3)^2*11

= 1.86*10^15 J

using,

log(E) = 4.8 + 1.5*M

log(1.86*10^15) = 4.8 + 1.5*M

==> M = 6.98

b) Energy that can be captured, E_captured = 16% of E

= 0.16*1.86*10^15

The average resistance force exerted on the diver by the water is 2,000 N

According to the law of conservation of energy, the mechanical energy is constant.

Mechanical energy (EM) is equal to the kinetic energy (Ek) + potential energy (Ep).

In the given problem, the diver comes to rest at  2.96 m below the surface of the water. Hence, at this point, his velocity is zero, so is its kinetic energy. Therefore, according to the law of  conservation of energy:

ΔE = - mg (h₂ - h₁)

Where:

m = mass of the diver

g = gravitation due to gravity

h = height

Hence,

ΔE = - 66.9 x 9.8 x (-2.96 - 6.07)

     = 5920.25 Joule

This is equivalent to the work done by the resistance force.

Hence,

W = ΔE = F . s

Work done by each force can be found as  

We know that, work done by a force is given by:

W =F d cosϕ,

where ϕ is the angle between Force and displacement vectors.

F₁ is in the direction of the displacement.

So,

W₁=F₁dcosϕ

     =(5.00N)(3.00m)cos0°

Force  F₂ makes an angle of

ϕ ₂=180°−θ

So,

W₂=F₂dcosϕ₂

      =(9.00N)(3.00m)cos120°

Force  F₃ is perpendicular to the displacement.

So,  W₃=F₃dcosϕ

Net Work done by three forces is  

As work is a scalar quantity, so total work done will be the algebraic sum of all the individual works.

The maximum horizontal distance (range) travelled by the ball is.

x = v2t

V2 = x/t

Wendy must stand 1.19m to the left of the edge of the roof so that the orange just barely passes over her head.

Bob's orange will travel down the slanted roof with a velocity of 4.47 m/s, and it will hit the ground 3.0 m below the edge of the roof. The height of the orange above the ground at the edge of the roof is 1.8 m, and the angle of the roof is 28.5° relative to the horizontal.

To calculate the distance Ar that Wendy has to stand from the edge of the roof, we must first calculate the time it takes for the orange to reach the ground. Using the equation for the vertical displacement of an object with an initial velocity, we can solve for the time, t:

d = v*t - (1/2)*g*t^2

0 = 4.47*t - (1/2)*9.8*t^2

t = 0.938s

Next, we must calculate the horizontal displacement of the orange from the time, t. Using the equation for the horizontal displacement of an object with an initial velocity and a constant acceleration we can solve for the displacement:

x = v*t + (1/2)*a*t^2

x = 4.47*0.938 + (1/2)*0*0.938^2

x = 4.19m

To calculate the distance Ar that Wendy must stand from the edge of the roof, we must subtract the horizontal displacement of the orange from the height of the edge of the roof:

Ar = 3.0 - 4.19

Ar = -1.19m

In a Geiger tube, the total time taken to create a pulse and then let the electrons recombine with the ions to again form a neutral state is about C. 300 μs

As we know that in G. M. Counter, slow positive ion takes 100μs to reach at cathode. If in this time, any other ion enters then no recording of this ion , known as dead time after this time also counter takes 100μs more, known as recovery time.

The sum of these times know as paralysis time of gm counter will be:

= (100+100+100)

= 300 μs.

Based on the information, the correct option is C.

The amount of tension in the back muscle is 3270 N.

Mass of object = 18.2 Kg

Mass of person = 40 Kg

Length = r = 0.5 m

Length at the spine at required position = r' = 0.33 m

Angle = θ = 10 degrees

Tension is defined as the force transmitted through a rope, string or wire when pulled by forces acting from opposite sides. The tension force is directed over the length of the wire and pulls energy equally on the bodies at the ends. Every physical object which is in contact exerts some force on one another.

Torque = Tension = T =

= T = r'sin10 -rmgsin90

= T = (0.5 X 40 X 9.8) / (0.33 X 0.1736)

= T = 3270 N

The complete question:

We will model the spine and upper body as a horizontal rigid rod or uniform density with a length of 50.0 cm and a mass of 40.0 kg. Assume that the person attempts to lift an object with their arms, which we will model as attached at the far end of the rod. Support of the back in this position is provided primarily by the erector spinalis muscle which we will model as being attached at one end to the spine at a point 33.0 cm from the hip at an angle of 10 degrees; the other end of the muscle is attached to the lower body below the hip. The object being lifted has a mass of 18.2 kg. Calculate the tension , in the back muscle for this scenario.

We set the derivative of F with respect to time equal to zero and solve for t since J=F avg t. The outcome is t=1.5103 s.  It is clear that the force, F(t), reaches its maximum at t=0.0015s, with Fmax equal to 4500N.

The formula Force (F) = Mass (M) x Acceleration (A), where the units are F (Newton) = Mass (kg) x Acceleration (m/s2), is used to determine the force of a kick.

The force exerted by the foot on the football during a kick is referred to as the action force. On the other side, the response force is the pressure the ball places on the foot. Because the action force and reaction force are of equal magnitude, no force is stronger than the other.
