The material which suppose Conduction called conductorsIn this heat is transmitted from one thermal to another .Metals are usually good conductors where as non metals are notExplanation:
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
Why burette calibrated from top to bottom?
Answer:
In order to measure the amount of solution added in or drained out, the burette must be observed at eye level straight to the bottom of the meniscus. The liquid in the burette should be completely free of bubbles to ensure accurate measurements.
What is the speed of a wave that has a frequency of 250Hz and a Wavelength of 1.5 m?
Question :-
What is the Speed of a Wave that has a Frequency of 250 Hertz and a Wavelength of 1.5 meter ?Answer :-
Speed of the Wave is 350 m/s .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 :-
Speed of the Wave = 375 m/s .[tex] \underline {\rule {180pt}{4pt}} [/tex]
Speed = Frequency Wavelenght
Speed
Speed
Hence :
Speed of the Wave = 375 m/s.
=
250 x 1.5
375

An 80g meter stick is supported at its 30 cm mark by a string attached to the ceiling. A 20 g mass is hung from the 80 cm mark what mass should be hung at the 5 cm mark on the meter stick to keep it horizontal and in equilibrium?
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].

Explain how the conservation of energy and the conservation of matter might still be considered true when put together in spite of the ability of each to convert into the other.
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.
What is the law of conservation of energy?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

Mr. Ben drove from Town A to Town B. For the first 3 hours, he
traveled at an average speed of 60 km/h, and after that, he drove at another average speed of 70 km/h. If the distance between Town A and B is 460 km, what was the total time for the whole journey?
The total time for the whole journey = 7 hours
Distance = Speed x time
Distance traveled for the first 3 hours
time = 3 hours
speed = 60 km/h
Distance = 60 x 3
Distance = 180 km
180 km was traveled for the first three hours
Total distance traveled = 460 km
Distance traveled at an average speed of 70 km/h = 460 - 180
Distance traveled at an average speed of 70 km/h = 280 km
Speed = Distance / time
70 = 280 / time
time = 280 / 70
time = 4 hours
Mr. Ben traveled 3 hours at an average speed of 60 km/h, he traveled 4 hours at an average speed of 70 km/h.
The total time for the whole journey = 3 hours + 4 hours
The total time for the whole journey = 7 hours

Two springs are attached to two hooks. When equal weights are suspended from each spring, both stretch the same amount. What can be assumed about the force constants of both?
It can be assumed that the spring constant will be same.Because the weight applied and the extension is same
What is spring force?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.

You are generating traveling waves on a stretched string by wiggling one end. If you suddenly begin to wiggle more rapidly without appreciably affecting the tension, you will cause the waves to move down the string.
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.
Four identical particles of mass m are mounted at equal intervals on a thin rod of length l and mass m, with one mass at each end of the rod.
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

Explanation:
Wheat is an anemophilous plant (form of pollination by which wind distributes pollen)They lack petals and sepals (outer whorls of the flower)The female plants consist of an ovary (female reproductive part) from which two styles (connecting stigma and ovary) ariseThe feathery stigma catches the pollen and sends it to the ovary for fertilization(b) wheat
Feathery stigma refers to wind pollinated flowers.
Wind pollinated flowers are smooth, light in weight, dull and does not contain nectar.
Wheat is light and does not contain nectar.

this demonstrate Newton's third law of motion?
Objects with mass, such as your cat's paw and toy string, will require inertia.
Objects in action, such as the string toy, will experience force.
For every motion from your cat's paw, there is unbalanced inertia from the string.
For every action your cat makes, there is an equal and opposite reaction from the string.
