Why is alpha rays not suitable to scan baggage at the airport?​

Physics
1 answer:
Inga [223]3 years ago
4 0

Answer:

Alpha particles are not used to check baggage in airport as these rays are not penetrated far through matter.

<u>Explanation: </u>

Alpha particles are produced by the <em>decay of a radioactive nucleus.</em> These alpha rays are <em>ceased by paper</em>. The <em>nucleus</em> of the helium atom is made up of <em>two protons and two neutrons</em> is the particle <em>ejected by alpha particle</em>.

As helium is <em>harmless and as an inert gas</em>, so these particles are not dangerous in themselves. The airport baggage security uses only X-ray scanners to inspect. These rays identify the <em>hidden items inside the baggage. </em>

Transformation 3 should Tracy removed from the list. Chemical energy transforms into gravitational potential energy.

<h3> What is the law of conservation of energy?</h3>

According to the Law of Conservation of Energy, energy can neither be created nor destroyed, but it can be transferred from one form to another.

The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.

Transformations that occur as an engine runs to power a car is;

1. Chemical energy of fuel transforms into thermal energy.

2. Thermal energy transforms into electrical energy used to lighten the bulb in a car.

3. Thermal energy transforms into kinetic energy to help to run the car.

Chemical energy transforms into gravitational potential energy is the incorrect energy transformation.

Hence, transformation 3 should Tracy removed from the list.

A motor spins up the flywheel with a constant torque of 50 n⋅m. how long does it take the flywheel to reach top speed?
dimulka [17.4K]

A motor spins upward the flywheel with a persistent torque of 50N⋅m.

What time does it take the flywheel to get to the top speed?
From the equation: 
Tj = J*dω/dt 


you can get the two equations: 
Δt1= J1*Δω/Tj = 240*125.66/50 = 603.17 sec 
Δt2= J2*Δω/Tj = 120*125.66/50 = 301.58 sec
