Answer:
10 meters
Explanation:
A wave is a natural phenomenon that travels through a material medium but does not have a permanent effect on the particles of the medium. It can either be electromagnetic or mechanical. The propagation of a wave can be represented by a sinusoidal graph, which has crests and troughs.
A crest is the point of maximum displacement, while trough is a point of minimum displacement. The distance between two crests or troughs gives the wavelength of the wave.
From the question, the horizontal distance between a crest to the next trough is 5 meters which is half of the wavelength.
Thus wavelength = 5 × 2
= 10
The wavelength is 10 meters.
When dry sand and water are both exposed to equal amounts of light, you will find that water is cooler than sand.
This is because the amount of heat needed to heat the water is less than that needed to heat sand, thus, sand heats faster.
Its true!!

Answer:
the correct answer is D. LIGHTNING results from the build up of electrical-energy polarity within clouds.
Explanation:
In simple words, Lightning is defined as a flash of light that is caused by the discharge of electricity in the atmosphere. An example of lightning is the flash of light often seen before the thunder is heard
Lightning is a naturally occurring electrostatic discharge during which two electrically charged regions in the atmosphere or ground temporarily equalize themselves, causing the instantaneous release of as much as one gigajoule of energy.
Lightning can be either connect from one cloud to another, or shoot from a cloud down to the ground. Lighting also has different appearances and is always accompanied by thunder. Types of cloud-to-ground lightning include staccato, forked, ribbon, and bead lightening.
