#3). The wavelengths of the four types of electromagnetic
radiation on that list line up like this:
Longest ... microwaves
next . . . . . infrared waves
next . . . . . visible light waves
shortest ... ultraviolet waves
#4). The word "visible" means "able to be seen". Infrared
light and ultraviolet light are not visible to human eyes.
Answer:
R = V^2 sin 2 θ / g range formula
R is a maximum for θ = 45 and R = V^2 g
g = V^2 / R = 3^2 / 15 = .6 m/s^2
Answer:
your answer is wavelength
Explanation:
the the highest service part of a weight is called the crest and the lowest part is the trough the vertical distance between the crest and the trough is the waist height the horizontal disc distance between two adjacent Crest or troughs is known as wavelengths
Answer:
87000 J ;
200 J
Explanation:
Workdone = mgh
Weight = mg = 290kN = 290 * 1000=290000 N
h = distance = 30 cm = 0.3 m
Workdone = 290000 * 0.3
Workdone = 87000 J
B.)
Workdone = Force * distance
Force = 4000 N
Distance, d = 5 cm = 0.05 m
Workdone by the woman, W = 4000N * 0.05m
W = 200Nm = 200 J
