Step-by-step explanation:
Answer:
Option(D)
Step-by-step explanation:
Diameter of the Sun (S) = 1.4 × 10⁶ km
Diameter of a planet mars (M) = 7000 km
≈ 7.0 × 10³ km
Ratio of the diameter of the Sun to the diameter of Mars
= 
= 
= 
= 
= 
Option (D) will be the correct option.
The pressure of the submarine at a depth of 23000 meters is 2.3575 * 10⁸ N/m²
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Pressure = density * acceleration due to gravity (g) * depth
g = 10 m/s², hence:
Pressure = 1025 * 10 * 23000 = 2.3575 * 10⁸ N/m²
The pressure of the submarine at a depth of 23000 meters is 2.3575 * 10⁸ N/m²
