Answer: Visible light makes up just a small part of the full electromagnetic spectrum. Electromagnetic waves with shorter wavelengths and higher frequencies include ultraviolet light, X-rays, and gamma rays.
Answer:
1.24 J
Explanation:
The work done by a force is given by
where
F is the magnitude of the force
d is the displacement
is the angle between the directions of F and d
In this problem,
F = 0.18 N is the average force exerted by the muscles
d = 6.9 m is the displacement
(we assume the direction of the force is parallel to the displacement)
Substituting,
Answer:
Pottasium iodide (KI)
Explanation:
product of this reaction is KI. this product is an ionic compound.
