Two blocks of masses 20 kg and 8.0 kg are connected togetherby
OleMash [197]

Answer:

14 N

Explanation:

The tension in the second string is puling both the masses of 20 kg and 8 kg with acceleration of 0.5 m s⁻²

So tension in the second string = total mass x acceleration

= 28 x .5 = 14 N . Ans..

Choose the correct statement regarding energy production in the interior of a star and energy production in a power plant. A sta
sergij07 [2.7K]

Answer:

A star uses fusion as an energy source by building larger atoms from smaller atoms.

Explanation:

Nuclear fission and fusion are two processes at which an atomic nucleus is changed to produce energy. Fission is the process splitting heavy atomic into lighter atomic nuclei.

So, fusion is the combination of smaller atoms to form larger atoms and star uses this as source of energy.

Fusion is the process at which light atomic nuclei are merged or fused together to form heavier nuclei.

The energy source for all stars is nuclear fusion. In a nuclear fusion reaction, the nuclei of two atoms combine to create a new atom. Most commonly, in the core of a star, two hydrogen atoms fuse to become a helium atom.

Calculate the speed of a proton after it accelerates from rest through a potential difference of 380 v .
nikitadnepr [17]

The magnitude of the change in potential energy is equal to the kinetic energy,

\left | \Delta U \right |= K

or                        

qV=\frac{1}{2} mv^{2}    

Here, V is potential difference, q is charge, m is mass and v is velocity.

We can also write,

v=\sqrt{\frac{2qV}{m} }

Given  V=380 V

Substituting this value with mass of proton, m=1.672\times10^{-27}  kg and charge of proton,q= 1.6\times10^{-19} C we get

v=\sqrt{\frac{2\times1.6\times10^{-19}C \times 380V}{1.672\times10^{-27}  kg} }\\\\v= 727.27\times10^{8} m/s =7.27\times10^{6}m/s

Therefore, the speed of proton is 7.27\times10^{6}m/s.

A circular coil (800 turns, radius = 0.063 m) is rotating in a uniform magnetic field. At t = 0 s, the normal to the coil is per
bija089 [108]

Answer:

0.000099T

Explanation:

For a circular coil the flux through a single turn changes by :

∆ = BAcos45° - BAcos90°

= BA cos 45°

During the interval of ∆t = 0.0165s

For N turn, Faraday's law gives the magnitude of emf as follows :

/E/= / -N BAcos45°/ ÷ ∆t

Since the loops are circular the area A of each loop is equal to πr square

B = /E/ ∆t ÷ Nπr square cos45°

= 0.042V × 0.0165/ 800 × 3.142 × 0.063^2 cos 45°

= 0.000693/7

= 0.000099T

= 9.9×10^-5T
