In physics, the rate of power in Watts could be determined by multiplying the voltage in volts, by the current in Amperes. In equation, that would be
P = IV
Substituting the values into the equation,
60 W = I*12V
I = 60/12
I = 5 Amperes
Therefore, a current of 5 Amperes is passing through the yellow wire.
Traditional media include the use of billboards, television and other forms of print media. Hence, <em>Dunkin</em><em>'</em><em> </em><em>Donuts</em><em> </em><em>billboard</em><em> </em>is a form of traditional media.
- Traditional media involves advertising channels which have been in use for a very long time.
- Traditional media include the use of radio, television, billboards and posters.
Therefore, the use of billboard to communicate the price of goods and service is a form of traditional media.

Answer:
305.5°
Explanation:
1.76 = (theta/360) × 2 × pi × 0.33
theta/360 = 0.8488263632
theta = 305.5774907
Answer:
D) 31 m, 19 Hz
Explanation:
The equation of the wave in the problem is
In general, the equation of a travelling wave is written as
where
A is the amplitude
is the wave number, with being the wavelength of the wave
is the angular frequency and f is the frequency
By comparing the two equations, we see that for this wave:
So now we can use the two equations for k and to find the wavelength and the frequency of the wave:
The force on the box is:
F = mgsin∅
If we multiply by this with the distance it traveled, we will know the work done by the box.
W = dmgsin∅
This work will be converted to elastic potential energy in the spring which is:
1/2 kx². Equating these and substituting values:
1/2 * 170 * x² = 4 * 13 * 9.81 * sin(30)
x = 1.73 m
The box's maximum speed will at the point right before contact with the spring, when the compression is 0.
