Answer: 0.5m/s²
Explanation:
Given that,
acceleration of bike (a) = ?
Mass of bike (m) = 20kg bike
(Note that the displacement of the bike is in the northerly direction)
constant unbalanced force (f) = 10 N
According to Newton's second law of motion, the acceleration of the bike will be directly proportional to force acting on it but inversely proportional to the mass of the bike.
Hence, Force α mass x acceleration
f = ma
Make a the subject formula
a = f / m
Now find the acceleration of the bike
a = 10N / 20kg
a = 0.5m/s²
Thus, the acceleration of the bike pedaled in the northerly direction is 0.5m/s²
<span>The width of the physical spectrum is shorter than that of the electromagnetic spectrum. The visible spectrum is the light that can be seen with the human eye, which we see as the colors red, orange, yellow, green, blue, indigo, and violet or ROY G. BIV. However, there are more wavelengths that can be seen beyond that, which are apart of the electromagnetic spectrum. For example, the UV rays, microwaves, and Gamma Rays cannot be seen by the human eye. Therefore, the electromagnetic spectrum is longer than the visible spectrum because there is so much more that humans can not see. The visible spectrum is only 400-750nm. The electromagnetic spectrum is 10 to the -14 to 10 to the 4 meters.</span>
