Answer:
F = 1000 g cm/s²
Explanation:
Let the weight of 1 ball is 50 gram
Acceleration, a = 20 cm/s²
We need to find the force exerted by a golf ball. We know that,
F = ma
So,
F = 50 g × 20 cm/s²
F = 1000 g cm/s²
So, the required force is 1000 g cm/s².
I didn't see any statements, but here are some similarities of those elements:
They all have the same number of valence electrons, they will become cations, they all will lose 2 electrons, they will behave similarly in chemical reactions, they have similar chemical properties, they all are in the alkaline earth metal family. Hope this helps! :)
Advantages of alloys:
-high strength-to-weight ratios
-a wide range of different alloys, to suit a range of different uses
-low density
Disadvantages of alloys:
-No fatigue limit
-prone to corrosion, so need protective finishes, particularly magnesium alloys
-Many alloys have limited strength, especially at elevated temperatures magnesium alloys have low strength
