Explanation:
Density is mass divided by volume:
D = M / V
Given V = 79000 cm³ and D = 13.6 g/cm³:
13.6 g/cm³ = M / (79000 cm³)
M = 1,074,400 g
M = 1,074 kg
Round as needed.
2/1 i think because if you start with the example of 4 then from air to water makes it 3 and then to glass makes it 2. Therefore you decrease from 4 to 2 which breaks down in the ratio 2:1
The force that the spring exerts is 1.31 N.
<h3>What is Spring force?</h3>
- The displacement (compression or expansion) and force constant of the specific spring determine the spring's force.
- It always takes action to get mass back to where it should be for equilibrium.
- The force applied to the spring and the energy it has stored are shown in the formulas below:
F = kx
Where,
x = displacement in the spring
k = spring force constant
<h3>Calculation of spring force:</h3>
Given,
k = 8.75 n/m
x = 0.150 m
Force exerted by the spring, F = kx
putting the values,
F = 8.75 x 0.150
= 1.3125 N
Hence, the force that the spring exerts is 1.31 N.
