Answer:
FalseA wave with a higher frequency have a shorter wavelength, the higher the sound it, the closer the arcs of the wavelength are, the faster the sound is, the shorter they are.
According to scied.ucar.edu ~ "The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. Light waves have very, very short wavelengths."
Hope this helps
Explanation:
May I have brainliest please? :)
A wave with a higher frequency has a longer wavelength is a false.
Relation of frequency, energy and wavelengthA wave with a higher frequency has a longer wavelength is a false statement because shorter wavelength have higher frequency and also higher energy.
We know that longer wavelength of a wave having shorter frequency and shorter energy while on the other hand, the shorter wavelength of a wave having higher frequency and higher energy so we can conclude that the statement is false.

What happens when the North Pole of one bar magnet is near the south Pole of another bar magnet?
A.Both attraction and repulsion
B.neither attraction nor repulsion
C.attraction
D.repulsion
When the North Pole of one bar magnet is near the South Pole of another bar magnet, they will attract each other. So, the correct option is C, attraction. This is because opposite magnetic poles attract each other, while like magnetic poles repel each other.
What is a magnetic field?A magnetic field is a region in space where a magnetic force can be detected. It is created by the movement of charged particles, such as electrons, protons, and ions. A magnetic field can be produced by a magnet, an electric current, or a changing electric field.
When the North Pole of one bar magnet is near the South Pole of another bar magnet, they will attract each other. This is because the magnetic field lines of the two magnets interact in such a way that they try to align with each other. Since opposite magnetic poles attract each other, the North Pole of one magnet will be attracted to the South Pole of the other magnet.
The magnetic force between the two magnets depends on the strength of the magnetic field and the distance between the magnets. The closer the magnets are, the stronger the magnetic force will be.
Therefore option C, attraction is correct.

which other metal can substitute (in place of) iron explain you answer.. Aluminum, copper or iron?
Answer+Explanation:
Titanium ( in place of iron)
Titanium could be an excellent replacement for iron when it comes to tensile strength versus weight. It would be the first choice as a building material metal and building skeletons/bridges would use titanium instead of iron.
Magnesium alloys (in place of aluminum)
Magnesium alloys potentially met the present demands for lighter and reliable construction. With comparable specific stiffness, higher specific strength and energy absorption magnesium alloys have the potential to replace steel and aluminum alloys.
aluminum (in place of copper)
Most non-copper metal cabling is aluminum, and it is often used in areas where copper is not a likely alternative. However, it is used more now as a replacement than it has ever been. It is cheaper than copper, and its relative density allows for more cable to be made from a ton of aluminum than a ton of copper.

What occurred during Rutherford’s experiment that led to his discovery of the nucleus?
Answer:
Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup." Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on these results, Rutherford proposed the nuclear model of the atom.

Calculate the energy and frequency of red light having a wavelength of 6.55 x 10⁻7m.
Answer:
E = 3.035× 10-¹⁹J = 1.9eV
f = 4.58 × 10¹⁴Hz
Explanation:
wavelength = 6.55 × 10-⁷m
c = 3 × 10⁸m/s
f = ?
E = ?
a) f = c/wavelength
f = 3 × 10⁸/6.55 × 10-⁷
f = 4.58 × 10¹⁴Hz
b) E = hc/wavelength
E = 6.626×10-³⁴ × 3 × 10⁸/ 6.55 × 10-⁷
E = 3.035 × 10-¹⁹J
1ev = 1.6 × 10-¹⁹J
Therefore E = 3.035/1.6 = 1.9eV

Which of the following are properties of ionic compounds?
A. hard solids with high melting and boiling points.
B. soft and good conductors of electricity.
C. both A and B
D. good conductors of electricity, but only when dissolved in water
Answer:a and d
Explanation:
The properties of ionic compounds are hard solids with high melting and boiling points and good conductors of electricity, but only when dissolved in water and the correct options are option A and D.
What are Ionic solids?Ionic solids are made up of ions joined together by ionic bonds. "Ionic bonding" is a type of chemical bond between a positive and a negatively charged ion where the transfer of electrons occurs.
They are too hard, and the ionic solids’ melting point is usually too high due to powerful forces between the anions and cations.
They are known as electrical insulators when they are in a solid-state. Apart from this, the molten salts do behave with electricity since the ions are not closed in the lattice.
Therefore, the properties of ionic compounds are hard solids with high melting and boiling points and good conductors of electricity, but only when dissolved in water and the correct options are option A and D.

Why is magnesium malleable?
Answer:
It is an Alkaline Earth Metal
Explanation:
Metallic bonding results from the delocalization of electrons from the parent metal atom so that positive ions are conceived to swim in a sea of electrons. This view of metallic bonding accounts for the malleability, and ductility of metals, as well as their properties of thermal and electrical conduction.
