If an object is projected with vertical speed given as
now the time of flight of the object that time in which it comes back on ground
now here we will have
now the range of projectile is given as
now here we know that
now the range is given as
now in order to have maximum range we can say
so we will have
so now we can say
so both speed must be same to have maximum horizontal range
Answer:
Noble gases because they have a full outer shell of electrons.
Explanation:
Noble gases usually called inert gases are generally non reactive gases. They belong to group 18 elements.They tend to not gain the electron or not give up a electron as they have full valence shells. Because they already have full valence shell and therefore full outer energy level, they are very stable and hardly react with any other elements.
D determined by its temperature
Answer:
The correct option is A: 121.5 MHz
Explanation:
If a pilot is not receiving ATC services at any point in time, the best frequency in the event of an emergency is 121.5 MHz. Various providers of ATC and enroute airliners constantly monitor this frequency and in case of an emergency, can quickly relay an information provided or even provide direct assistance to the caller.
