Impulse equals to the force into the actual time period of the applied force . thus the force here given is 245.300 N and time is 0.05 thus the impulse is 12.265 Ns
Answer:
k=320N/m
Explanation:
Step one:
given data
Let the initial/equilibrum position be x
mass m1= 0.2kg
F1= 0.2*10= 2N
elongation e= 9.5cm= 0.095m
mass m2=1kg
F2=1*10= 10N
elongation e= 12cm= 0.12m
Step two:
From Hooke's law, which states that provided the elastic limits of a material is not exceeded the extention e is proportional to applied Force F
F=ke
2=k(0.095-a)
2=0.095k-ka----------1
10=k(0.12-a)
10=0.12k-ka----------2
solving equation 1 and 2 simultaneously
10=0.12k-ka----------2
- 2=0.095k-ka----------1
8=0.025k-0
divide both side by 0.025
k=8/0.025
k=320N/m
Density of liquid is 1 g/mL.
<h3>What is density of a substance?</h3>
Density is the ratio of the mass and the volume of a substance
Mathematically density of a substance is given as follows:
The density of the substance is:
mass of liquid = 172 - 137 = 35 g
volume of liquid = 35 mL
Density of liquid = 35 g/35 mL
Density of liquid = 1 g/mL
In conclusion, density is obtained as a ratio of mass and volume.

C. Physicalist chemist and biologist conducted experience in gather collection that changed existing scientific knowledge about the oceans
Explanation:
The voyage of Her Majesty's Ship was highly important because it furnished scientists with rich evidence about a lot of phenomenon under study and this changed existing scientific knowledge about the ocean.
- H.M.S II was an expedition to study and map the ocean floor using some sophisticated and newer devices.
- It was through this expedition that the theory of plate tectonics was modified and became a theory
- The bathymetry of the ocean floor was also carried out.
- The mid-oceanic ridge was discovered through the expedition.
- Some rare species of organisms were also obtained from the ocean floor in this process.
- The H.M.S second expedition after the world war was very crucial and helped furthered scientific knowledge about the oceans.
