Assuming conservation of energy:
Energy before = 7000 + 4000 = 11 000 MJ
Energy after = 2000 + Kinetic = 11 000
Therefore Kinetic = 11 000 - 2 000
Kinetic = 9 000 MJ
Not exercising in high-air pollution areas
limiting exercise in hot climates to the early morning and evening
using exercise equipment as it was designed to be used
4.5 Joules. I think it'd be 4.41, but when you round it, it's 4.5.
Answer:
flux=13.92W/m^2
Explanation:
The heat transfer by conduction consists in the transport of energy through particles that are together, that is to say by means of solids, Newton developed an equation that allows to know the heat transported in a flat plate knowing the cross sectional area A, Thickness L, conductivity K and a temperature difference between the internal and external surface.
Q=KA(t2-t1)/L
To know the heat flux we simply divide both sides of the equation by the area.
Flux=K(t2-t1)/L
where
K=0.029w/mk
L=25mm=0.025m
t2-t1=12 ° C
solving
Flux=(0.029)(12)/(0.025)
flux=13.92W/m^2
Answer:
Yes
Explanation:
In the International System of Units (SI), energy is measured in joules. One joule is equal to the work done by a one- newton force acting over a one- metre distance
