Answer:
heat and power
Explanation:
is the simultaneous production of electricity and heat both of which are used
Answer:
-18 Nm
Explanation:
Impulse = Change of Momentum
I = ∆p
I = mv2 - mv1
I = 3 x 3 - 3 x 9
I = 9 - 27
I = -18 Nm
Answer:
The time required by the impulse to travel from foot to brain equals 0.019 seconds
Explanation:
For uniform motion the distance, speed, time are related by the equation
In our case since the person is 1.90 meters tall so the nerve impulse will have to cover a distance of 1.90 meters at a speed of 100 m/s.
Hence the time required for the impulse to travel from foot to the brain can be calculated as
Answer:
The thickness of the film is
Explanation:
The relation between the refraction index, and a wavelength is given by
<em>where is the number of fringes, is the wavelength of the incident light, and is the thickness of the film</em>.
<u>From this relation</u>, we have that
wich gives us that
is the thickness of the film.
