Answer:
p₁ = - p₂
the moment value of the two particles is the same, but its direction is opposite
Explanation:
When a nucleus divides spontaneously, the moment of the nucleic must be conserved, for this we form a system formed by the initial nucleus and the two fragments of the fission, in this case the forces during the division are internal and the moment is conserved
initial instant. Before fission
p₀ = 0
since they indicate that the nucleus is at rest
final moment. After fission
= m₁ v₁ + m₂ v₂
p₀ = p_{f}
0 = m₁ v₁ + m₂v₂
m₁ v₁ = -m₂ v₂
p₁ = - p₂
this indicates that the moment value of the two particles is the same, but its direction is opposite
Hello!
Your answer is all of the above. Science is a very broad field, and it is the thing which has engineered most, if not all, of our technology today. Take for example microwave ovens. These could not have been possible without science, as it was science that realized that "microwaves" (a type of wave length) even existed.
Hope this helps!
Answer:
Explanation:
A rain drop has diameter given as
so the radius of the rain drop will be
now the volume of the rain drop is given as
now weight of the rain drop is given as
now this weight of the rain drop is counterbalanced by force due to electric field
so we have
Answer:
a = 0.16 [m/s²]
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
Vf = final velocity = 3.2 [m/s]
Vo = initial velocity = 1.1 [m/s]
t = time = 13 [s]
a = acceleration [m/s²]
Now replacing:
![3.2=1.1+a*13\\2.1=13*a\\a=0.16[m/s^{2} ]](https://tex.z-dn.net/?f=3.2%3D1.1%2Ba%2A13%5C%5C2.1%3D13%2Aa%5C%5Ca%3D0.16%5Bm%2Fs%5E%7B2%7D%20%5D)
Answer:
An aircraft flying at sea level with a speed of 220 m/s, has a highest pressure of 29136.8 N/m²
Explanation:
Applying Bernoulli's equation, we determine the highest pressure on the aircraft.
where;
P is the highest pressure on the aircraft
is the density of air = 1.204 kg/m³ at sea level temperature.
V is the velocity of the aircraft = 220 m/s
P = 0.5*1.204*(220)² = 29136.8 N/m²
Therefore, an aircraft flying at sea level with a speed of 220 m/s, has a highest pressure of 29136.8 N/m²
