Answer:
ø = 53.7º
Explanation:
The measurement of kinetic energy in an object is calculated based on the object's mass and velocity.
KE=1/2mv²
where m is mass
v is velocity
given data
m=0.60 kg
v=4.0 m/s
So
KE = 1/2 . 0.6 . 4^2
KE= 4.8 J
All the KE is converted into GPE ("Gravitational potential energy (GPE) - energy stored in an object when moving the object to a height")
4.8 = 0.6 . 9.8 . ∆h
∆h = 0.816 m
This is the height that the object rises.
cos ø = (2 – 0.816 ) / 2 = 0.592
ø = 53.7º
6.6 * V/m is the electric field amplitude of an electromagnetic wave whose magnetic field amplitude is 2.20 mT
<h3>Given the data in the question:</h3>
Magnetic field amplitude = Bm = 2.20 mT = 2* T
Electric field amplitude = Em = ?
<h3>Electric field:</h3>
An electric field is a field created by electrically charged particles that attracts or repels other electrically charged particles surrounding it.
The greatest strength of the electric and magnetic fields is known as the electric field amplitude.
It can be said to be,
Em = c * Bm
Where, c is the speed of light(c = 3 * m/s)
Bm is the magnetic field amplitude
On substituting the values we get,
Em = c * Bm
Em = 3 * m/s * 2.20 * T
Em = 660000 V/m
Em = 6.6 * V/m

Answer:
your answer is 187=223-323=gang
Explanation:
To develop this problem it is necessary to apply the concepts related to the Dopler effect.
The equation is defined by
Where
= Approaching velocities
= Receding velocities
c = Speed of sound
v = Emitter speed
And
Therefore using the values given we can find the velocity through,
Assuming the ratio above, we can use any f_h and f_i with the ratio 2.4 to 1
Therefore the cars goes to 145.3m/s
