Answer:
Ocean-floor sediments can also be used to determine past climate. ... Ice cores contain more 16O than ocean water, so ice cores have a lower 18O/ 16O ratio than ocean water or ocean-floor sediments. Water containing the lighter isotope 16O evaporates more readily than 18O in the warmer subtropical regions
Explanation:
Answer:
Silver is a malleable and ductile metal having atomic number 47 and symbol Ag. Gold on the hand has atomic number 79 and symbol Au. It is also ductile and malleable. Both are soft and lustrous in nature. Both are transition metals.
Bronze is an alloy of majority of copper and some amount of tin. Formation of alloy enhances the properties of the metal and its industrial use. Bronze is harder than copper and easily fusible and easy to cast. It is resists corrosion.
Silver and gold have different atomic numbers, different colors. Both are transition elements where as Bronze is an alloy.

Answer:
Explanation:
Given:
- cross sectional area of the wire,
- density of aluminium wire,
- young's modulus of the material,
- wave speed,
<u>We have mathematical expression for strain as:</u>
...............................(1)
and since, 
where, T = tension force in the wire
equation (1) becomes:
............................(2)
<u>Also velocity ofwave in tensed wire:</u>
...................................(3)
where: 
linear mass density of the wire
Now, equation (3) becomes
............................(4)
Using eq. (2) & (4) for tension T
putting the respective values
