Answer:
A d-t graph's slope is equivalent to the speed and direction while a v-t graph's slope is equal to its acceleration. A constant slope for a d-t graph means that the speed is constant. The area underneath a v-t graph would be its distance.
Explanation:
Is there any chemical names listed ?
Answer:
Electromagnetic waves have crests and troughs similar to those of ocean waves. The distance between crests is the wavelength. The shortest wavelengths are just fractions of the size of an atom, while the longest wavelengths scientists currently study can be larger than the diameter of our planet!

particles that make up material B.
Answer:
third charge must be placed at x = -298.11 cm
Explanation:
When two opposite charges are placed in a straight line then the electric field is always zero at a point near to the charge of lesser magnitude
so here let say the point where electric field is zero lie on the left side of 7.00 micro C charge at a distance "x" from it
so we will have net electric field due to both charges will be zero at that point
so electric field of charge 1 must be equal to the electric field of charge 2
so we have
now square root both sides
so third charge must be placed at x = -298.11 cm
