What planet is famous for the beautiful rings that surround it?.

Conduction

Explanation:

According to online, "thermal energy is just a fancy word for heat energy. It's a form of both potential and kinetic energy. If you remember, the electrons of an atom have potential energy. Once you apply pressure to the electrons, they start to move rapidly, banging into each other, and releasing thermal energy as heat."

Thermal energy transfers occur in three ways: conduction, convection, and radiation

Kinetic energy

Answer:

At the same speed as before

Explanation:

Speed is dependent on the tension in the string, and since the tension isn't changing, the speed of the waves will also not change.

Answer:

the conservation of both matters because without each other the balance of nature will be destroyed it helps in such a way that the food chain will be maintained.

it is as such considered because without matter there would be no energy and the reverse is such.

it is still considered because without one another famous atomic theories wouldn't have been made such as gas, liquid and solid.

in conclusion all these work together to balance the galaxy as a whole

Both the conservation of energy and the conservation of matter is important because, without each other, the natural equilibrium will be disrupted.

According to the Law of conservation of energy. Energy can not be created nor be destroyed it can transfer from one to another form.

The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.

The conservation of both is important because without each other, the natural equilibrium will be disrupted, and it aids in the maintenance of the food chain.

It is seen as such because there would be no energy without matter and vice versa.

Hence both the conservation of energy and the conservation of matter is important

Answer:

Moment of inertia at distance L / 2    from center

I1 = M (L / 2)^2 = M L^2 / 4

I2 = M (L / 6)^2 = M L^2 / 36      at a distance of L / 6

I (1/2 rod) = I1 + I2 = M L^2 (1/4 + 1/36) = M L^2 (9 + 1)/ 36 = 5/ 18 M L^2

I for entire rod = 2 I (1/2 rod) = 5 / 9 M L^2

Question :-

Answer :-

Explanation :-

As per the provided information in the given question, we have been given that the Frequency of the Sound Wave is 250 Hertz. Its Wavelenght is given as 1.5 Meter. And, we have been asked to calculate the Speed of the Wave.

For calculating the Speed , we will use the Formula :-

[tex] \bigstar \: \: \boxed {\sf { \: Speed \: = \: Frequency \: \times \: Wavelenght \: }} [/tex]

Therefore , by Substituting the given values in the above Formula :-

[tex] \Longrightarrow \: \: \sf { \: Speed \: = \: Frequency \: \times \: Wavelenght }[/tex]

[tex] \Longrightarrow \: \: \sf { \: Speed \: = \: 250 \: \times \: 1.5 }[/tex]

[tex] \Longrightarrow \: \: \bf { \: Speed \: = \: 375 }[/tex]

Hence :-

[tex] \underline {\rule {180pt}{4pt}} [/tex]

Speed = Frequency Wavelenght

Speed

Speed

Hence :

Speed of the Wave = 375 m/s.

=

250 x 1.5

The value of the dependent variable is based upon changes in the values of the independent variable.

The term independent variable has to do with the variable that is being intentionally manipulated in an experiment. The dependent variable is the variable that changes in value as the  independent variable is manipulated.

Answer:

[tex]104\; {\rm g}[/tex], assuming that the meter stick is uniform with the center of mass precisely at the [tex]50\; {\rm cm}[/tex] mark.

Explanation:

Refer to the diagram attached. The meter stick could be considered as a lever. The string at the [tex]30\; {\rm cm}[/tex] mark would then act as the fulcrum of this lever.

The [tex]m_{A} = 20\; {\rm g}[/tex] mass at the [tex]80\; {\rm cm}[/tex] mark is at a distance of [tex]r_{A} = 50\; {\rm cm}[/tex] to the right of the fulcrum at [tex]30\; {\rm cm}[/tex].

The weight of the [tex]80\; {\rm g}[/tex] meter stick acts like a weight of [tex]m_{B} = 80\; {\rm g}[/tex] attached to the center of mass of this meter stick. Under the assumptions, this center of mass of this meter stick would be at the [tex]50\; {\rm cm}[/tex] mark, which is [tex]r_{B} = 20\; {\rm cm}[/tex] to the right of the fulcrum at [tex]30\; {\rm cm}[/tex].

Let [tex]m_{C}[/tex] be the mass attached to the meter stick at the [tex]5\; {\rm cm}[/tex] mark. This mass would be at a distance of [tex]r_{C} = 25\; {\rm cm}[/tex] to the left of the fulcrum at [tex]30\; {\rm cm}[/tex].

At equilibrium:

[tex]\begin{aligned} & m_{C}\, r_{C} && (\text{mass on the left of fulcrum})\\ &= m_{A}\, r_{A} + m_{B} \, r_{B} && (\text{mass on the right of fulcrum})\end{aligned}[/tex].

Solve for [tex]m_{C}[/tex], the unknown mass attached to the meter stick at the [tex]5\; {\rm cm}[/tex] mark:

[tex]\begin{aligned}m_{C} &= \frac{m_{A}\, r_{A} + m_{B}\, r_{B}}{r_{C}} \\ &= \frac{20\; {\rm g} \times 50\; {\rm cm} + 80\; {\rm g} \times 20\; {\rm cm}}{25\; {\rm cm}} \\ &= 104\; {\rm g}\end{aligned}[/tex].

It can be assumed that the spring constant will be same.Because the weight applied and the extension is same

The force required to extend or compress a spring by some distance scales linearly with respect to that distance is known as the spring force. Its formula is

F = kx

Two springs are attached to two hooks. When equal weights are suspended from each spring, both stretch the same amount.

Extensions will be greater in spring B than in spring A.Remember that the force constant represents the spring's stiffness,

Hence It can be assumed that the spring constant will be same.Because the weight applied and the extension is same.

The mass of an alpha particle greater than the mass of an electron. Hence option A is correct.

The alpha particle is a positively charged particle that is similar to the nucleus of the helium-4 atom and is spontaneously released by some radioactive substances. It is made up of two protons and two neutrons bonded together and has a mass of four units and a positive charge of two. Ernest Rutherford discovered and named alpha particles (1899), which he and colleagues employed in studies to examine the structure of atoms in thin metallic foils. This investigation produced in the original notion of the atom (1909-11) as a miniature planetary system with negatively charged particles (electrons) circling a positively charged nucleus. Later, in the first artificially created nuclear transmutation (1925), Patrick Blackett blasted nitrogen with alpha particles, converting it to oxygen.

Alpha particle is heavier than the electron cause alpha particle has 2 neutron and two protons which makes it heavier.

Hence option A is correct.

The Schwarzschild radius of a black hole depends on the mass and density of the black hole because volume is the space that an object occupies.

Volume is defined as the amount of space occupied by an object. It can be measured in cubic units. If the black hole has more volume then it has more radius and vice versa.

So we can conclude that the Schwarzschild radius of a black hole depends on the mass and density of the black hole because volume is the space that an object occupies.
