Answer:The FitnessGram PACER Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The test is used to measure a student's aerobic capacity as part of the FitnessGram assessment. Students run back and forth as many times as they can, each lap signaled by a beep sound.
Explanation:
Answer:
We will use the combined gas equation.
The final volume V₂=931.74 mL
Explanation:
The combined gas equation shows the interrelationship between the volume, the pressure and the absolute temperature of a fixed mass of an ideal gas,
P₁V₁/T₁=P₂V₂/T₂
Because we are looking for the volume after the initial conditions havre been varied, we will call this volume, volume 2 ( V₂)
Let us make it the subject of the equation.
V₂=(P₁V₁T₂)T₁P₂
P₁=1.50 ATM
P₂=1.20 ATM
V₁=800 mL
V₂=?
T₁=(20+273)K=293 K
T₂=0+273 K=273 K
V₂=(1.50 ×800×273)/(293×1.2)
V₂=931.74 mL
Answer:
The empirical formula of the oxide is CuO
Explanation:
Copper(II) oxide or cupric oxide is the inorganic compound with the formula CuO
The law of conservation of energy states that energy cannot be created nor destroyed, but it transforms from one form to another.
this also applies in a food chain, for energy is decreased by 90% when moving down to the next animal (or trophic level), but it is not created nor destroyed, for the first source of energy in a food chain is always the sun, and the sun is an infinite source of energy
