Two bullets are fired simultaneously, horizontally and with different speeds from the same place. Which bullet will hit the ground first ?
(a) the faster one (b) the slower one
(c) both will reach simultaneously
(d) depends on the masses.
The ionization enthalpy of an atom depends on the number of electrons and protons (nuclear charge) of that atom. Now, the isotopes of an element have the same number of...
When two coins are tossed simultaneously, the possible outcomes are(H, H),(H, T),(T, H),(T, T) which are all equally likely. Here (H, H) means head up on the first coin (say on Rs.1) and...
(d) 100 m.
Explanation:
In the first case Range = 50 = (u2 /g) Sin(2x15°) = (u2 /2g) => (u2 /g)=100 In the second case range = (u2 /g) Sin(2x45°) = (u2...
(b) A will go higher than B.
Explanation:
The force of resistance of air will add to retardation of both the body but its magnitude will depend upon mass of the objects...
