The coordinates of the event in system K can be found using the Lorentz transformation equations, and they are (10/3 m, 3.5 m, 3.5 m, 8/3 m/c).
The Lorentz transformation equations relate the coordinates of an event in one reference frame to the coordinates of the same event in another reference frame that is moving with a constant velocity relative to the first reference frame.
The equations are as follows:
x = γ(x' + vt')
y = y'
z = z'
t = γ(t' + vx'/c^2)
Where γ is the Lorentz factor, which is given by:
γ = 1/√(1-v^2/c^2)
In this case, v = 0.8c, so γ = 1/√(1-(0.8c)^2/c^2) = 5/3.
Plugging in the values for x', y', z', t', v, and γ into the Lorentz transformation equations, we get:
x = (5/3)(2 m + (0.8c)(0)) = 10/3 m
y = 3.5 m
z = 3.5 m
t = (5/3)(0 + (0.8c)(2 m)/c^2) = 8/3 m/c
Therefore, the coordinates of the event in system K are (10/3 m, 3.5 m, 3.5 m, 8/3 m/c).

c. the motor wave effect
d. the wave frequency effect
Answer:
a
Explanation:
Answer:
The tension in the part of the cord attached to the textbook is 6.58 N.
Explanation:
Given that,
Mass of textbook = 2.09 kg
Diameter = 0.190 m
Mass of hanging book = 3.08 kg
Distance = 1.26 m
Time interval = 0.800 s
Suppose,we need to calculate the tension in the part of the cord attached to the textbook
We need to calculate the acceleration
Using equation of motion
Put the value into the formula
We need to calculate the tension
When the book is moving with acceleration
Using formula of tension
Hence, The tension in the part of the cord attached to the textbook is 6.58 N.
Answer:
Gravitational potential energy is converted into kinetic energy
Explanation:
At the top of the hill, the roller coaster car has gravitational potential energy, which is given by:
where m is the mass of the car, g is the gravitational acceleration, h is the height of the hill.
As the car descends the hill, it gains speed (v), so it also gains kinetic energy, given by:
where v is the speed of the car.
The mechanical energy of the car is the sum of its potential energy and kinetic energy:
In absence of friction, the law of conservation of energy states that the mechanical energy of the car is constant. Therefore, since as the car moves down the hill the potential energy decreases (because the height, h, decreases), it means that the kinetic energy must increase (and this is wy the speed increases). So we can say that gravitational potential energy is converted into kinetic energy.
15.0cm
45.0cm
55.0cm
60.0cm
85.0cm
Answer:
Explanation:
its 85 cm because it just is in meters it would be .8m which would be decent distance to hear it
