Answer:
Volts/Meter
Newtons/Coulomb
Explanation:
Volts/ Meter and Newtons/Coulomb both are same and the units of Electric field intensity or electric field strength.
Electric field strength E is the force per unit charge. It is measured in Newton/Coulomb in SI unit. It is a vector quantity directed in the direction of force.
Mathematically,
Electric field strength = Force/Charge
E = F / q₀
= Newton / Coulomb = NC⁻¹ 1
We know that
Newton = Joule/meter 2
Also
Volt = Joule/Coulomb 3
So put 3 in 2 we get
Newton = (Volt Coulomb)/meter put in 1
E = (Volt Coulomb)/(meter Coulomb)
= Volt / meter
Hence
Newton / Coulomb = Volt / meter
Answer: A. Transverse
Explanation:
Sound is a mechanical transverse wave, it travels faster in solids than in liquids or gases. This is because the speed of the mechanical waves is determined by a relationship between the elastic properties of the medium in which they are propagated and the mass per unit volume of the medium.
In addition, the speed of sound varies with changes in the temperature of the medium. This is because an increase in temperature means that the frequency of interactions between the particles that transport the vibration increases, hence this increase in activity increases the speed.
Hence:
<h3>Sounds travels in a <u>transverse</u> wave</h3>
Insulators- fur, plastic, lots of non metals
Conductors- metals, wire, most metals
