speed is the magnitude of velocity which is given as 90 km/hr and it does not change. only the direction change , the direction at any time is given by the tangent to the circle at that time and location.
from the diagram , at north side, the velocity is directed in west direction
The sodium atom, Na, contains 11 protons, 11 electrons, and 13 neutrons.
formed by the process of glaciation.
Acceleration will always be samei.e.
Acceleration=g= 9.81 m/s^2
If research results can be replicated, it means they are more likely to be correct. Replication is important in science so scientists can “check their work.” The result of an investigation is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.
