First of all, the question is vague as you haven't mentioned the medium of propagation of the wave, which is extremely crucial.

For example light travels at <span>299,792</span> km/second in vacuum, but in certain semiconductors, it travels as slow as 9 km/second. Sound, ocean and seismic waves don't exist in vacuum at all.

If you mean the maximum possible speed any of these options can attain in any medium of choice for the different options, then the answer would be
b. radio waves, which travel exactly at the speed of light in vacuum (299,792 km/second) and with an almost similar(slightly less) speed in air. (Radio waves are nothing but electromagnetic waves with low frequency)

An ion accelerated through a potential difference of 115 V experiences an increase in kinetic energy of 7.37 x 1017 J. Calculate

riadik2000 [5.3K]

Answer: $6.408(10)^{-19} C$

Explanation:

This problem can be solved by the following equation:

$\Delta K=q V$

Where:

$\Delta K=7.37(10)^{-17} J$ is the change in kinetic energy

$V=115 V$ is the electric potential difference

$q$ is the electric charge

Finding $q$ :

$q=\frac{\Delta K}{V}$

$q=\frac{7.37(10)^{-17} J}{115 V}$

Finally:

$q=6.408(10)^{-19} C$

The direction of the magnetic field produced by an electric current will change when the direction of the _ changes.

Scorpion4ik [409]

Answer: Electric current

Explanation :

The direction of the magnetic field produced by an electric current will change when the direction of the electric current changes.

For example :

If a current is flowing in a straight length of wire, the magnetic field is described by a concentric circle (using right-hand rule).

Let the field lines are in the clockwise direction and when the direction of current is reversed then the direction of the magnetic field is in anticlockwise direction.

What force controls the movement of the planets around the sun, holds together stars grouped in galaxies, and galaxies grouped i

JulijaS [17]

Answer:

Gravity.

Explanation:

The force that controls the movement of the planets around the sun, holds together stars grouped in galaxies, and galaxies grouped in clusters is called gravity.

This ultimately implies that, gravity is considered to be a universal force of attraction that acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.

Additionally, the gravity of earth makes it possible for all physical objects to possess weight.

Weight can be defined as the force acting on a body or an object as a result of gravity.

Mathematically, weight is given by the formula;

$Weight = mg$

Where;

m is the mass of an object.

g is acceleration due to gravity.
