Answer: 3.9 MW
Explanation:
1 W = 1 J/s
260000 J/s (15 s) = 3,900,000 = 3.9 MW
Answer:
1. Police Weren't Able To Find Any Real Leads
2. They Didn't Find Any Clues To The Killer Until 18 Years Later
Explanation:
It was unknown at the time, but it would go on to take 18 years for her killer to be arrested and tried for her death. The initial case went on from 1995 to 1997 but ended up closing when the police department was unable to find any real leads.
Answer:
a) the oscillation of this field is in phase, when the magnetic field goes in the negative direction of y, the elective field goes in the positive direction of the z axis
b) the direction of the magnetic field perpendicular to this electric field and the speed in the negative x the magnetic field goes in the x direction and in the direction (1, - 1.1)
Explanation:
a) the polarization the determined wave oscillates the electric field, which is the z axis
As the wave travels on the negative x-axis and the magnetic field is perpendicular, this field goes on the positive y-axis
the oscillation of this field is in phase, when the magnetic field goes in the negative direction of y, the elective field goes in the positive direction of the z axis
be) in the case of a polarization in the xi plane the magnetic field must go in the direction of the magnetic field perpendicular to this electric field and the speed in the negative x the magnetic field goes in the x direction and in the direction (1, - 1.1)

Answer:
m₁ v = m₂ v
Explanation:
Let's define a system formed by the two objects, for this system the forces during the crash are internal, action and reaction, so that the memento is conserved,
Let's write the initial moment, before shock
p₀ = m₁ v + 0
Final after crash
= 0+ m₂ v
How the moment is preserved
p₀ =
m₁ v = m₂ v
It tells us that peer speed
m₁ = m₂
Since the two masses are the same, it shows that the moment is preserved in this collision.
The kinetic energy is
Initial
K₀ = ½ m₁ v² + 0
Final
= 0 + ½ m₂ v²
K₀ =
½ m₁ v² = ½ m₂ v²
m₁ = m₂
which is true because it indicates that the objects are the same.
