Answer:
alkaline earth metals
Group 2 metals, the alkaline earth metals, have 2 valence electrons, and thus form M2+ ions. The halogens, Group 17 , reach a full valence shell upon reduction, and thus form X− ions
Explanation:
Answer:
P=mv 2250*25=56250
Explanation:
p of truck =2250*25 =56250
since p of truck = p of car
then p of car = 56250
therefore p of car = 1210 * v
or, 56520=1210v
or,v= 56520/1210=46.48
so, v of car is 46.48m/s
Answer:
Explanation:
The time taken by a transverse wave to propagate from one end to another depends on the number of oscillation made by the wave itself. If the total number of oscillation of the wave is known, the time taken by the wave to propagate through can be determined.
Note that the term "period" is the time taken by a transverse wave to complete one oscillation. So if we know the number of oscillation made in one second by the wave and the total oscillation made, then we can know determine how long it will take a transverse wave to propagate from one end of the string to the other
