Answer:
Work done,W= 250J
Displacement , s = 60
We know that, Work done = Force x displacement
i.e , W = Fxs
250 J = F x 60m
F = 250/60
=4.16 N
Hence , 4.16 N of Force is applied on the body.
Answer:
Current in the loop is 0.063 A
Explanation:
Number of turns in the coil N = 150
Radius of the circular loop r = 7.5 cm = 0.075 m
So area ![A=\pi r^2=3.14\times 0.075^2=0.0176m^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2%3D3.14%5Ctimes%200.075%5E2%3D0.0176m%5E2)
Magnetic field B = 1.5 T
Maximum torque is given ![\tau =0.25Nm](https://tex.z-dn.net/?f=%5Ctau%20%3D0.25Nm)
We have to find current in the coil
Torque on circular coil in magnetic field is equal to
![\tau =BINA](https://tex.z-dn.net/?f=%5Ctau%20%3DBINA)
![0.25=1.5\times I\times 150\times 0.0176](https://tex.z-dn.net/?f=0.25%3D1.5%5Ctimes%20I%5Ctimes%20150%5Ctimes%200.0176)
I = 0.063 A
Explanation:
H₂ + Cl₂→ 2HCl chemical reaction
In a chemical reaction, a chemical change occurs when new kinds of products are formed. The products contains the atoms that are combining together and they obey the law of conservation of matter.
In a chemical reaction, elements, compounds and molecules are involved.
The reaction depicted is a typical combination or synthesis reaction in which two species reacts to form products. New compounds are formed
H + H → He + n nuclear reaction
In a nuclear reaction, nuclides combines or they are disintegrated due to their instability.
The above reaction is a typical nuclear fusion reaction in which light hydrogen atoms combines to form a heavy nuclide of helium. The reaction involves the transmutation and production of new element.

Answer:
![0.62\:\mathrm{s}](https://tex.z-dn.net/?f=0.62%5C%3A%5Cmathrm%7Bs%7D)
Explanation:
Since the universal SI unit for velocity is meters/second, let's convert ft/s to m/s:
![10\:\mathrm{ft/s}=3.048\:\mathrm{m/s}](https://tex.z-dn.net/?f=10%5C%3A%5Cmathrm%7Bft%2Fs%7D%3D3.048%5C%3A%5Cmathrm%7Bm%2Fs%7D)
We can use the following kinematics equation to solve this question:
![v_f=v_i+at](https://tex.z-dn.net/?f=v_f%3Dv_i%2Bat)
What we know:
- The initial velocity,
, is
- (physics concept) The final velocity must be equal in magnitude but opposite in direction to the initial velocity (
) - Acceleration,
, is acceleration due to gravity at about
Solving for
:
![-3.048=3.048+(-9.8t),\\-6.096=-9.8t,\\t=\frac{-6.096}{-9.8}\approx \boxed{0.62\:\mathrm{s}}](https://tex.z-dn.net/?f=-3.048%3D3.048%2B%28-9.8t%29%2C%5C%5C-6.096%3D-9.8t%2C%5C%5Ct%3D%5Cfrac%7B-6.096%7D%7B-9.8%7D%5Capprox%20%5Cboxed%7B0.62%5C%3A%5Cmathrm%7Bs%7D%7D)
