Answer:
0.283m
Explanation:
Speed (v) = wavelength × Frequency (f)
Wavelength = speed/ frequency
Wavelength = 343/ 1210 = 0.283m
Answer:
because they are found freely in nature uncombined so they are highly reactive with other elements
Answer:
centripetal Force
Explanation:
<u>Given:</u>
Mass of the body
Radius of the circle
Time period
The centripetal Force acting on the body is given by F
Hence the centripetal force acting on the body is calculated
Free weights include barbells and dumbbells
