Answer:
20 5/6 sec
Explanation:
To find the solution we divide 5000 by 240
However, when you see a problem, always try to simplify
5000/240=500/24=250/12=125/6
Now the division is much easier
20 5/6 sec

Abiotic components are the non-living components in an ecosystem, like water, minerals, sunlight and air.
Biotic components are the living components that make up an ecosystem, like plants and animals. So bacteria is not an example of an abiotic component.
Answer:
1.75 m/s
Explanation:
k = Spring constant = 490 N/m
m = Mass of object = 5.8 kg
x = Displacement of spring = 0.19 m
v = Speed of object at the equilibrium position
The potential energy of the spring will balance the kinetic energy of the mass
The speed of the mass as it returns to the equilibrium position is 1.75 m/s.
Been a while since i've done a problem like this so i might be wrong in the "work" aspect
your system starts with 1200J
you add 700J of heat-
add 700 to 1200
1200+700
and your system does 400J of work
since work is being done by the system, the energy is leaving the system hence you subtract
1900-400
the result is then 1500
