"red-sensitive" just means that the nerves are able to see red light
Answer: The speed is 15.5 m/s
Explanation:
The kinetic energy can be written as:
K = (1/2)*m*v^2
where m is the mass and v is the speed.
Then we have that:
18 j = (1/2)*0.15kg*v^2
Now we solve this for v.
√(18*2/0.15) = v
15.5 m/s = v
Answer:
2940.1 joules would you burn in climbing stairs all day.
Explanation:
Work = W = F d
going up stairs would be against force of gravity
W = mgh
where h is the height
the question is not complete because we need speed or distance
h = v t
so assuming 1 step per second
h = 86,400 steps 7inchs/step 0.0254 m/inch
h = 15362 m
so from this
W = 800 N 15362
= 12289600 J
that means YOU need 12289600 J to walk 1 step per second all day
divide that by 4180 J /Kcal
Kcal =
=
= 2940.1 Kcal
if you ran faster you would use more energy 2 steps per second would mean 5880 Kcal.
A high-mass star has layers that are arranged in order of b. Temperature for fusion.
<h3>What is the temperature of fusion?</h3>
The temperature at which a substance transforms from a solid to a liquid is known as its melting point. The solid and liquid phases are in equilibrium at the melting point. Pressure affects a substance's melting point, which is typically reported at a standard pressure such 1 atmosphere or 100 kPa. There are two main categories of fusion reactions: those that maintain the ratio of protons to neutrons and those that convert protons to neutrons. The solid-liquid and liquid-to-gas transitions are connected with the typical heats of fusion and vaporization, respectively, for each substance.
