Answer:
What happens to the wavelength of a wave if you double the frequency?
If the frequency of a wave is increased, what happens to its wavelength? As the frequency increases, the wavelength decreases. 2. If the frequency is doubled, the wavelength is only half as long.

Answer:
B
Explanation:
Friction always eventually stops whatever is in motion.
Answer:
The distance of car form the mirror is 330 cm.
Explanation:
height of object, h = 140 cm
height of image, h' = 14 cm
radius of curvature, R = 60 cm
focal length, f = R/2 = + 30 cm
Let the distance of image is v and the distance of object is u.

Use the formula of focal length

Voltage = (current) x (resistance)
Voltage = (4.00 A) x (330 Ω)
<em>Voltage = 1,320 V (D)</em>
