1) nuclear fusion
During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. During this process, radiant energy is released.
Normal force is the force exerted when an object is on an surface. So an example could be a pile of books on top of a table.
Answer:
0.125 volts
Explanation:
The induced emf can be sufficient to stimulate neuronal activity.
One such device generates a magnetic field within the brain that rises from zero to 1.5 T in 120 ms.
We need to find the induced emf within a circle of tissue of radius 1.6 mm and that is perpendicular to the direction of the field. The formula for the induced emf is given by :
![\epsilon=-\dfrac{d\phi}{dt}](https://tex.z-dn.net/?f=%5Cepsilon%3D-%5Cdfrac%7Bd%5Cphi%7D%7Bdt%7D)
Where
is magnetic flux
So,
![\epsilon=-\dfrac{d(BA)}{dt}\\\\=2\pi r\times \dfrac{dB}{dt}\\\\=2\pi \times 1.6\times 10^{-3}\times \dfrac{1.5-0}{120\times 10^{-3}}\\\\=0.125\ V](https://tex.z-dn.net/?f=%5Cepsilon%3D-%5Cdfrac%7Bd%28BA%29%7D%7Bdt%7D%5C%5C%5C%5C%3D2%5Cpi%20r%5Ctimes%20%5Cdfrac%7BdB%7D%7Bdt%7D%5C%5C%5C%5C%3D2%5Cpi%20%5Ctimes%201.6%5Ctimes%2010%5E%7B-3%7D%5Ctimes%20%5Cdfrac%7B1.5-0%7D%7B120%5Ctimes%2010%5E%7B-3%7D%7D%5C%5C%5C%5C%3D0.125%5C%20V)
So, the induced emf is equal to 0.125 volts.
Force required is 100 N
<u>Given that;</u>
Rate of acceleration = 5 m/s²
Mass of object = 20kg
<u>Find:</u>
Force required
<u>Computation:</u>
Force = Mass × Acceleration
Force required = Rate of acceleration × Mass of object
Force required = 20 × 5
Force required = 100 N

Answer:
The potential difference between the places is 0.3 V.
∴ 1st option i.e. 0.3V is the correct option.
Explanation:
Given
Work done W = 3J
Amount of Charge q = 10C
To determine
We need to determine the potential difference V between the places.
The potential difference between the two points can be determined using the formula
Potential Difference (V) = Work Done (W) / Amount of Charge (q)
or
![\:V\:=\:\frac{W}{q}](https://tex.z-dn.net/?f=%5C%3AV%5C%3A%3D%5C%3A%5Cfrac%7BW%7D%7Bq%7D)
substituting W = 3 and q = 10 in the formula
![V=\frac{3}{10}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B3%7D%7B10%7D)
V
Therefore, the potential difference between the places is 0.3 V.
∴ 1st option i.e. 0.3V is the correct option.
