Dark energy is the energy associated with the motion of particles of dark matter. FALSE

Dark Energy is a hypothetical form of energy that exerts a negative, repulsive pressure, behaving like the opposite of gravity.

Another definition of dark energy is as follows; it is a hypothetical form of energy that produces a force that opposes gravity and is thought to be the cause of the accelerating expansion of the universe.

The force of gravity which force from dark energy opposes is given as;

F = Gm₁m₂/R²

where;

Thus, the force of gravity which is being opposed by the force produced by the dark energy is directly proportional to the mass of two objects in the universe and inversely proportional to the square of the distance between the two objects.

For 500nm the second order maxima 2m away would be 1cm

For 650nm the second order maxima 2m away would be 1.12 cm

Maxima and minima are the maximum or the minimum value of a function within the given set of ranges.

The separation between the second order maxima is: ymax=2cm y max = 2 c m .

Assumption of infinite source distance gives plane wave at  slit. So, all amplitudes are in phase.

Here, sepration between 2nd order maxima will be given by

= 2(yd) = 2 (m+1/2) lamda×D/d

= 2 (2+1/2) lamda D/d = 5 lamda D/d

Here, d= 0.50mm=0.50×10^-3m

D=2m

For lambda = 500nm

Separation = 5 lamda D/d = 5(5×10^-7m)(2m)/(0.5×10^-3m) = 1 CM

For lamda = 650nm

Separation = 5 lamda D/d= 5(650×10^-9m) (2m) /(0.5×10^-3m) = 1.12cm

The voltage supplied determines how strong the electrostatic force is inside a capacitor, and the length among the plates determines how weak it is.

The energy held in the capacitor stays unchanged as plates spacing increases, while capacitance falls. As a result, there is only a potential rise inside the differential here between plates.

By virtue of energy conservation, kinetic energy (KE) must be proportional to the change in potential energy (qV), either conversely. In terms of numbers, the voltage among the plates and the electron's energy in electron-volts are identical. For instance, a 5000-V voltage differential results in 5000-eV electrons. Energy in potential is position-dependent. To put it another way, it varies based here on weight and height of the object. The mass and initial velocity affect the kinetic energy of that object. When we consider a waterfall, we can see that the motionless liquid now at peak of something like the drop possesses potential energy.

The virial theory argued that kinetic energy is equivalent to half of potential energy's negative figure. The double of negative kinetic energy is called potential energy. The kinetic energy's opposite, amount of energy, is the same.

The velocity of the piece b is expressed as vb = (ma×va)/mb.

The Law of Momentum conservation states that the Momentum of particle before collision will be equal to momentum of particles after collision. If we assume that the mass of parent nuclei is M and its velocity is V, then according to law of momentum conservation

MV = - ma×va + mb×vb ( we use negative sign because part a travels left)

Now, the initial velocity of parent nuclei is zero because it was at rest that is V = 0. So, the equation will be

0 = - ma×va + mb×vb

ma×va = mb×vb

False, a personal foul does not necessarily involve illegal entry or excessive timeouts, though they can be part of a personal foul.

A personal foul is a penalty in certain sports, such as basketball and American football, that involves an illegal action by a player. A personal foul occurs when a player has unsportsmanlike conduct, illegal entry, or excessive timeouts. Unsportsmanlike conduct is defined as any action that is not considered to be ethical or respectful within a sporting event. This includes taunting, arguing with a referee, or showing disrespect towards another player or team.

Illegal entry is when a player enters a restricted area without permission or authorization. This can be a violation of the playing rules or a foul against another player. Excessive timeouts are when a team uses all of its allotted timeouts in a game or a player takes an excessive amount of time to make a decision, such as when taking a free throw.

All of these actions, when committed by a player, can be considered a personal foul. A personal foul is a violation of the rules that can result in a variety of consequences, from a warning to a technical foul, to a disqualification from the game.

The moment of inertia (Icm) of the uniform flat disk without the point mass = Icm = MR².

The moment of inertia with respect to point P on the disk without the point mass =  Ip = 3MR².

The total moment of inertia (of the disk with the point mass with respect to point P) = I total = 5MR².

We know from the case, that:

Mass = 2M

Radius = R

Mass at the edge = M₂ = 1/2M

Distance between the centre of mass to point P = p = R

Distance of the point mass to point P = d = 2R

We know that the moment of inertia for an uniform flat disk = 1/2mr².

(a) Then the moment of inertia for the uniform flat disk is:

= Icm = 1/2mr²

= Icm = 1/2(2M)(R²)

= Icm = MR²

(b) Next, we will find the moment of inertia of the disk with respect to point P. We know that point P is positioned at the arc of the disk. Hence,

= Ip = Icm + mp²

= Ip = MR² + (2M)R²

= Ip = 3MR²

(c) Then, the total moment of inertia of the disk with the point mass is:

A bowling ball of mass 7.25 kg and radius 10.8 cm rolls without slipping down a lane at 3.10 m/s. Then the total mechanical kinetic energy of a bowling ball is 48.8 J.

Given that, mass = 7.25 kg

Radius = 10.8 cm = 10.8/100 m = 0.108 m

Velocity = 3.1 m/s

The total mechanical kinetic energy is nothing but the sum of kinetic energy due to rotation and kinetic energy due to translation. It can be written as

KE = 1/2* m* v² + 1/2* I*ω²

where, I is the moment of inertia of the bowling ball about its centre

ω is the angular velocity

As the ball is in rotation, v = r * ω

And I = 2/5 * m * r²

So, the total mechanical kinetic energy is

KE = 1/2* m* v² + 1/2* I*ω² = 1/2* m* v² + 1/5* m * v²

⇒ 7/10 m * v² = 7/10 * 7.25 * 3.1² = 48.77 J ≈ 48.8 J

The substance's density is defined as its mass per unit of volume (volumetric mass density or specific mass). Although the Latin letter D may also be used, the symbol for density that is most usually used is (the lower case Greek letter rho). where V is the volume, is the density, and m is the mass. Weight per unit volume is a common informal definition of density, however this is incorrect scientifically; the actual term is specific weight. The US oil and gas industry serves as one illustration of this. A pure substance's mass concentration in numbers is equal to its density. To make density comparisons between different systems of units easier, it is occasionally replaced by the dimensionless quantity "relative density" or "specific gravity," which is the ratio of the density of the material to that of a standard material, usually water. If a substance's relative density to water is less than one, it will float in it. Temperature and pressure have an impact on a substance's density. This variation is frequently not very noticeable for solids and liquids, but it is very noticeable for gases. As pressure is applied, an object's density rises, which reduces the object's volume. With a few rare exceptions, as temperature increases, a substance's density decreases as its volume grows.
