How do the linear equation and quadratic equation are differ? What do we suffer on earth? What if we would live on the moon /sun
2 answers:
A quadratic equation is a parabola and a linear equation is a straight line.
- Quadratic Equation is an equation in which the power of variable mostly x is two.
- Standard quadratic equation is
- Any linear equation have form like
- The moon has no atmosphere, no weather and no oceans of water. Its surface is in a perpetual vacuum.
- Because the moon's gravity is only one-sixth that of the Earth's gravity, Apollo astronauts had to risk of stumbling or falling.
- Astronauts on the moon were protected from the extreme temperatures by their spacesuits. The suits had several layers of insulating material covered by a highly reflective outer layer.

Answer:
Assume that ;
.
Density of the disk: approximately .
Weight of the disk: approximately .
Buoyant force on the disk if it is submerged under water: approximately .
The disk will sink when placed in water.
Explanation:
Convert the dimensions of this disk to SI units:
- Diameter:
.
- Thickness
.
The radius of a circle is 1/2 its diameter:
.
Volume of this disk:
.
Density of this disk:
.
indicates that the disk will sink when placed in water.
Weight of the object:
.
The buoyant force on an object in water is equal to the weight of water that this object displaces. When this disk is submerged under water, it will displace approximately of water. The buoyant force on the disk will be:
.
The size of this disk's weight is greater than the size of the buoyant force on it when submerged under water. As a result, the disk will sink when placed in water.
