Answer:
0.7
Explanation:
Reasoning The distance between adjacent crests is the wavelength l. Since the speed of each wave is v = 3.00 × 108 m/s and the frequencies are known, the relation v = fl can be used to determine the wavelengths. The equation v = fl applies to any kind of periodic wave.

Explanation:
Answer:
42.99°
Explanation:
= Kinetic friction force
= Pulling force at angle
= Weight of the box = 150 N
Kinetic friction force
Pulling force at angle
N = Pulling force
According to question
Applying Newton's second law in the vertical direction we get
The angle is 42.99°
Explanation:
Work cannot be increased by using a machine of some kind.
