Answer:
The density of the metal is 5200 kg/m³.
Explanation:
Given that,
Weight in air= 0.10400 N
Weight in water = 0.08400 N
We need to calculate the density of metal
Let be the density of metal and be the density of water is 1000kg/m³.
V is volume of solid.
The weight of metal in air is
.....(I)
The weight of metal in water is
Using buoyancy force
We know that,
....(I)
Put the value of in equation (I)
Put the value of Vg in equation (II)
Hence, The density of the metal is 5200 kg/m³.

Answer:
v = 349.23 m/s
Explanation:
It is required to find the orbital speed for a satellite from the center of mass.
Mass of Mars,
The orbital speed for a satellite is given by the formula as follows :
So, the orbital speed for a satellite is 349.23 m/s.
