Answer:
W = 750 [J]
Explanation:
The question should be related to work, work in physics is defined as the product of force by distance. In this way, we can use the following equation.

where:
F = force = 30 [N]
d = distance = 25 [m]
W = work [J]
Now replacing:
![W=30*25\\W=750 [J]](https://tex.z-dn.net/?f=W%3D30%2A25%5C%5CW%3D750%20%5BJ%5D)
Xrayssssss because they are the closest to gamma rays, and they have the highest frequency
They both are types or categories of nitrogen containing bases present in nuclei acids of DNA and RNA.
Purines are 2 Ring or Carbon Ring, Nitrogen containing bases. That consist of these 2 rings next placed next to each other. These examples include - Adenine and Guanine.
Pyrimidines are 1 or single Ring Nitrogen containing structures. There are 3 nitrogenous bases that are categorized as pyrimidines. Cytosine, Thymine, and Uracil.
An applied force must be applied to move a load. This applied force must be large enough to overcome any opposing forces in order to move the load.
An average cyclist generates about 183 watts while doing 19 mph or 30.4 kph. Power = force × velocity. Force of a pedalling applied by a human for achieving 30.4 kph = 183/8.44 = 21.68 newtons. This is for upright bicycles.
