<span>Circumference = 2 * pi * r
62.8318 = 2 * 3.14159 * 10 cm
62.8318 * 15 rotations / 42 seconds = 22.44 cm / second
22.44 cm / 100 cm per meter = .2244 m / s</span>
Answer:
An object at rest will stay at rest and an object in motion will stay in motion unless it is acted upon by an unbalanced/external force.
The Cosmic Ray is a natural way for nuclear fission and nucleosynthesis to occur. It refers to the formation of chemical elements from the impact of cosmic rays on an object.
<span>Weight of the skydiver m = 500 N
Terminal velocity V = 90 km/h
Here the weight of the person acts as the force, so based on the Newton's third law the applied is the force what we but in the opposite direction making the resistance. So the air resistance exerted on Suzie will be her weight that is 500N</span>
I think it's The fossil record. The same animal fossil is in Africa and South America. The animal could have not swim across so its the fossil record
