Answer:
Average power output of athlete = 11025 Watts
Explanation:
Work done is defined as the product of force applied and the displacement perpendicular to the force.
Work =
Power is defined as work done per unit time.
Power =
Here the person lifts 900 kg.
Height = 2.5 m
Time interval = 2 seconds
Force =
=
= 8820 N
Work done =
=
= 22050 J
Power =
= 11025 Watt
I believe the answer for 1) is
PEgrav = mass • g • height
PEgrav = m *• g • h
Answer:
2 atoms of oxygen in carbon dioxide
Explanation:
The mass of water moving around on Earth’s surface causes the amount of gravitational force.
Answer:
A) Concentration of A left at equilibrium of we started the reaction with [A] = 2.00 M and [B] = 2.00 M is 0.55 M.
B) Final concentration of D at equilibrium if the initial concentrations are [A] = 1.00 M and [B] = 2.00 M is 0.90 M.
[D] = 0.90 M
Explanation:
With the first assumption that the volume of reacting mixture doesn't change throughout the reaction.
This allows us to use concentration in mol/L interchangeably with number of moles in stoichiometric calculations.
