Answer:
v = 0.713[m/s]
Explanation:
Kinetic energy is defined as the product of mass by the squared velocity of a body. In this way with the following expression we can have the kinetic energy as a function of velocity.
where:
m = mass = 85 [kg]
v = velocity [m/s]
Ekin = kinetic energy = 2.16*10 [J]
![2.16*10 = 0.5*85*v^{2}\\v =\sqrt{0.508} \\v= 0.713[m/s]](https://tex.z-dn.net/?f=2.16%2A10%20%3D%200.5%2A85%2Av%5E%7B2%7D%5C%5Cv%20%3D%5Csqrt%7B0.508%7D%20%5C%5Cv%3D%200.713%5Bm%2Fs%5D)
Answer:
1. Ultraviolet
Explanation:
This is called the Balmer series. Transitions ending in the ground state (n = 1) are called the Lyman series, but the energies released are so large that the spectral lines are all in the ultraviolet region of the spectrum.
Answer:
You can make a magnetic field stronger by doing the following:
1. Increasing the number of turns on the coil.
2. Increasing the current.
3. Placing an iron core inside the solenoid.
