As we know that frequency and wavelength are dependent on each other
and this is given by
here we know that
= wavelength
f = frequency
c = speed of wave
while for energy and intensity of wave we know that
Energy = 
here A = amplitude of wave
so energy directly depends on amplitude of wave
so correct answer will be
<em>A) Energy</em>
Answer:
Curl up test.
Explanation:
The curl up test is done to check the strength of the abdomen muscles and the stability of the core muscles. The strength of the core muscles determines the stability of the body.
The curl up test is done to test the abdomen strength and endurance and the strength of the back muscles.
The test requires the following materials: A flat cushioned surface(clean) and a measuring strip
- The measuring strip is placed on the mat under the students legs so that their fingertips are just resting on the nearest edge of the measuring strip. The feet cannot be held or rest against an object. Keeping heels in contact with the mat, the student curls up slowly, sliding their fingers across the measuring strip until the fingertips reach the other side, then curls back down until their head touches the mat. There should be 20 curl-ups per minute
The moon's orbital plane is different from that of the earth's orbit around the sun due to which lunar and solar eclipses do not occur every month.
<h3 /><h3>What is a solar eclipse?</h3>
When the moon passes in front of Earth and the sun, it creates a solar eclipse and casts a shadow across the globe.
Only during the new moon phase, when the moon travels squarely between the sun and Earth and casts shadows on its surface, can a solar eclipse occur.
Due to the moon's orbit being five degrees off-center from Earth's orbit around the Sun, lunar eclipses do not happen every month and the Moon often passes above or below the shadow.
Lunar eclipses would happen every month if there were no tilt. Eclipses of the sun and the moon happen equally often.
Hence lunar and solar eclipses aren't coming every month.

Answer:
Explanation:The elements that can form basic compounds are;
Rubidium
Arsenic
Silicon
Antimony
Rubidium, Arsenic, Silicon, Antimony are the substances that can for the basic compounds. I think sulfur also play its role somehow in formation of basic compounds.
-- Your foot hits the street.
-- Your foot exerts a force down onto e pavement.
-- The pavement exerts an equal force up against your foot. This is the force that stops you from going any farther down.
