On the periodic table, atomic radius generally decreases as you move from left to right across a period (due to increasing nuclear charge) and increases as you move down a group (due to the increasing number of electron shells). In a group, the size of an atom increases as one proceeds from top to bottom. This is due to the successive addition of shells as one move from one period to the next in a group.
The speed of a boat is that of the current of water is 40:3. The boat goes along with the current in 3 hours 8 minutes. It will come back in
A boat can cover 200 km in downstream in 10 hours and 150 km in upstream in 15 hours. Find the distance travelled by the boat in still water in 5 hours.
