A single element on the periodic table
At it's maximum height the acceleration is still 9.8m/s. On the earths surface, all objects are constantly under acceleration due to gravity. It is perculiar, but true. Under acceleration, only the velocity changes (as a general rule).
Answer:
The eccentricity of an elliptical orbit is defined by the ratio e = c/a, where c is the distance from the center of the ellipse to either focus. The range for eccentricity is 0 ≤ e < 1 for an ellipse; the circle is a special case with e = 0.
Explanation:
Answer:
The speed is 
Explanation:
From the question we are told that
The length of the rod is 
The induced emf is 
The magnetic field is 
Generally the speed is mathematically represented as
=> 
=>
Answer:
All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor. Arranged this way, groups of elements in the same column have similar chemical and physical properties, reflecting the periodic law.
