Answer:
a The velocity of the third particle is 
b The total kinetic energy increase 
Explanation:
To solve this question we are going to be using the concept of conservation of momentum which is mathematically represented as
From the question
Mass of unstable atomic nucleus 
Mass of x-axis particle 
Velocity of x-axis particle 
Mass of y-axis particle 
Velocity of y-axis particle 
Since the initial mass is known we can obtain the mass of the third particle
Using the conservation of mass mathematical expression
Using the mathematical expression above for conservation of momentum
The above is the vector solution now to obtain the value in numeric form we evaluate the magnitude of the vector
To obtain the total increase in kinetic energy which is mathematically represented as
![E =\frac{1}{2} [(5.20*10^{-27})(6.0*0^{6})^2 + (8.44*10^{-27})(4.00*10^6)^2+\\\\(2.16*10^{-27})(21.285*10^6)^2]](https://tex.z-dn.net/?f=E%20%3D%5Cfrac%7B1%7D%7B2%7D%20%5B%285.20%2A10%5E%7B-27%7D%29%286.0%2A0%5E%7B6%7D%29%5E2%20%2B%20%288.44%2A10%5E%7B-27%7D%29%284.00%2A10%5E6%29%5E2%2B%5C%5C%5C%5C%282.16%2A10%5E%7B-27%7D%29%2821.285%2A10%5E6%29%5E2%5D)
Answer:
C)The side that the charge is on, the top.
Explanation:
As we know that
1)More flux is possible, when the field is perpendicular to the cross sectional area.
2)Electrical field lines are more power full in this side because the charge is near to the top side.
3)Those sides are electric field parallel to area that sides have minimum flux.
So
The side that the charge is on, the top ,have least flux traverse.
Option C is correct.
Answer:
Momentum (P)= 3.15Kg.m/s
Explanation:
Because momentum by definition is the product of mass and velocity, therefore, it's calculated by the formula;
P=mv,,,
where 'P' Is the momentum
'm' is mass in Kilograms, note that mass should be in Kilograms, therefore the 450grams should be converted to kilograms by dividing it with a 1000, i.e (450g×1kg/1000g)= 0.45kg, and now you can substitute in the formula because you have everything you need to find momentum in the right si units.
so P=mv
P=0.45Kg×7m/s
P=3.15Kg.m/s
Answer:
The North American tectonic plate.
Explanation:
recall the formula for momentum: p = m * v
the subatomic particles have very small masses while high speeds, so the product results in values with negative exponents in scientific notation.
Negative exponents also result for the house fly when converting mg into kg (10^-6).
The positive exponents in scientific notation for the momentum come for the gigantic mass of the continental plate which exceeds the negative exponents contributed by the small velocity.
