Well the options r not well described anyways, the answer goes:
1) Foods rich in carb, sugars, proteins...
2) Lack of activity/exercise
3) Not proper use of medicines
4) Imbalanced hormone
5) Dehydration
6) Stress (in some situations)
7) High intake of unhealthy beverages (i.e, juices, alcohol & alike)
And much more
Hope this was helpful :)
Answer:
The time taken by the airplane to take off, t = 11.46 s
Explanation:
Given data,
The initial velocity of the airplane, u = 24 m/s
The acceleration of the plane, a = 8 m/s
The distance covered until take off, d = 800 m
Using the III equation of motion,
v² = u² +2as
= 24² + 2 x 8 x 800
= 13376
v = 115.65 m/s
Using the first equation of motion,
v = u + at
t = (v-u) / a
= (115.65 - 24) / 8
= 11.46 s
Hence, the time taken by the airplane to take off, t = 11.46 s
I am attaching the missing figure
If we assume 100% efficiency, this means that the input power of the transformer must be equal to the output power
We divide output/input
240,000/12,000 = 20
This means that the transformer has a turns ratio of 1:20
<span>
ns/np = 20/1 = 20
The voltage is amplified 20 times by the transformer, but this also means that the current decreases by a factor of 20, so the total power remains the same.</span>
Opaque materials absorb all the light that shines on them. None of it comes out the other side. That's why they're opaque.
Opaque materials become warmer when light shines on them, because <em>they absorb the energy</em> carried by the light that shines on them. (According to the law of Conservation of Energy, that energy has gotta go somewhere.)
The equation for heat would be q = m*Delta T* S
Where q = the heat absorbed in joules
m = mass
Delta T = change in temperature
s = specific heat capacity of the material
for iron s = 0.450
Delta T = 23 - 13 = 10 degrees Celsius
m is given as 27 grams.
q = 27 * 10 * 0.450 = 121.5 joules
You may need to round the answer depending on what the teacher is looking for.
