--vertical from ground to top--
v^2 = u^2 + 2as
with v= 0, a=g, s=u^2/(-2g)
g on the moon is 1/6
u is equal, then it goes 6 times higher on the moon.
v = u + at
with v= 0, a=g, t = u/(-g)
g on the moon is 1/6
u is equal, then it takes 6 times longer on the moon.
--horizontal--
s = vt , v is equal
t on the moon is 6 time longer
it moves 6 times farer on the moon
Answer:
Pu-244 and 94 alpha decay = U -240 and 92
D. They are heterotrophs that digest food internally.
Answer: E = 0.85
Therefore the efficiency is: E = 0.85 or 85%
Explanation:
The efficiency (e) of a Carnot engine is defined as the ratio of the work (W) done by the engine to the input heat QH
E = W/QH.
W=QH – QC,
Where Qc is the output heat.
That is,
E=1 - Qc/QH
E =1 - Tc/TH
where Tc for a temperature of the cold reservoir and TH for a temperature of the hot reservoir.
Note: The unit of temperature must be in Kelvin.
Tc = 300K
TH = 2000K
Substituting the values of E, we have;
E = 1 - 300K/2000K
E = 1 - 0.15
E = 0.85
Therefore the efficiency is: E = 0.85 or 85%
