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?
Answers
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.
Answers
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.

What is the speed of a wave that has a frequency of 250Hz and a Wavelength of 1.5 m?
Answers
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.
=

Is the mass of an alpha particle greater than, less than, or equal to the mass of an electron?.
Answers
The mass of an alpha particle greater than the mass of an electron. Hence option A is correct.
What is alpha particle ?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.

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.
Answers
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
