Explanation:
The expression is :
A =[LT], B=[L²T⁻¹], C=[LT²]
Using dimensional of A, B and C in above formula. So,
Comparing the powers both sides,
2n+m=1 ...(1)
2m-n=1 ...(2)
Now, solving equation (1) and (2) we get :
Hence, the correct option is (E).
Answer:
The particle A will strike on the screen to the right (in -y₀). The particle B will strike to the left of the screen (in y₀), at the same distance than particle A from the x-axis but in the opposite direction. The particle C will strike to the right of the screen (in -y₁), the same direction than particle A, but nearer to the x-axis (see attached image)
The exact positions in the screen are (the point [0,y,0]):
Explanation:
The electric charges that move throw a region of space with a magnetic field will suffer a magnetic force (explain by Lorentz Force law). This force will force the particle to change direction but won't change its speed module. Therefore magnetic force act as a centripetal force.
The Lorentz Force law can be written as:
For particle A:
For particle B:
For particle C:
The force applied in each particle in the module is the same as you can see. Nevertheless, their directions are not. In the case of particles A and C, the force has a negative direction in the y-axis while in case B has a positive direction in the y-axis.
Knowing that the magnetic force is a centripetal force, we can find the radius of curvature:
For particle A:
For particle B:
For particle C:
Now we can obtain the exact point in the screen where the particle will strike. We can see than particle A and C are affected by the same force (same module and direction), but the radius of curvature of particle C is twice the one of particle A. Therefore the particle C will strike nearer to the x-axis than particle A.
In each case we can use Pythagoras Theorem to determine the point Y where the particles strike:
and in the triangle form
Therefore:
Answer:
A combustion reaction is a major class of chemical reactions, commonly referred to as "burning." In the most general sense, combustion involves a reaction between any combustible material and an oxidizer to form an oxidized product. It usually occurs when a hydrocarbon reacts with oxygen to produce carbon dioxide and water. Good signs that you're dealing with a combustion reaction include the presence of oxygen as a reactant and carbon dioxide, water, and heat as products. Inorganic combustion reactions might not form all of those products but remain recognizable by the reaction of oxygen.

Answer:
28.0 cm
Explanation:
Displacement is final position minus initial position.
Δx = xf − xi
Δx = -64.9 cm − -92.9 cm
Δx = 28.0 cm
