Answer:
amount of work done is
Explanation:
Formula for work done by force field
where
r(t) is parametrization of line
as it is straight line so
thus,
r(t) = (1-t)(-1,1) + t(3,-3)
= (-1+t,1-t) + (3t - 3t)
= (-1+t +3t, 1-t-3t)
r(t) = (4t -1, 1- 4t)
r'(t) = (4,-4)
putting value in above integral
![= 4[ -16 \frac{t^3}{3} + 16\frac{t^2}{2} - 3t]_{0}^{1}](https://tex.z-dn.net/?f=%3D%204%5B%20-16%20%5Cfrac%7Bt%5E3%7D%7B3%7D%20%2B%2016%5Cfrac%7Bt%5E2%7D%7B2%7D%20-%203t%5D_%7B0%7D%5E%7B1%7D)
Answer:
just trace a picture of it.
Answer:
The thyroid gland produces thyroxine (referred to as T4), which is a relatively inactive prohormone. The highly active hormone is triiodothyronine (referred to as T3).
Key actions of adrenaline include increasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, enlarging the pupil in the eye (see photo), redistributing blood to the muscles and altering the body's metabolism, so as to maximise blood glucose levels (primarily for the brain).
Answer: The correct answer is an emission line spectrum.
Explanation:
When the electrons are excited to the higher energy level, the energy is absorbed in this case.
When the electrons in the atom step down to lower energy levels in a thin cloud of hot gas then the radiation will emit.
The electron will lose energy in this case in the form of radiation. There will be an emission line spectrum.
