Answer:

1) 50 facing towards the right

2) 150 facing right

3) 200 facing right

4) 0- no direction

5) 50- facing left

6) 50 facing right

Explanation:

forces in opposite directions and equal magnitudes counteract each other. in number 2 they face the same direction so they would just be added. in number 4 they oppose each other so would be subtracted

At a distance of 14.0 m from a point source, the intensity level is measured to be 80 dB. At what distance from the source will
Ivan

Answer:

d_2=19.8m

Explanation:

The problem can be solved easily, because the relationship between intensities I_1 and I_2 at distances d_1 and d_2 respectively can be written as:

\frac{I_2}{I_1} =\frac{d_1^2}{d_2^2}

Where:

I_1=Intensity\hspace{3}1\\I_2=Intensity\hspace{3}2\\d_1=Distance\hspace{3}1\\d_2=Distance\hspace{3}2

In this case:

I_1=80dB\\I_2=40dB\\d_1=14m\\d_2=?

Solving for d_2

d_2=\sqrt{\frac{d_1^2 *I_1}{I_2} } =\sqrt{\frac{14^2*80}{40} } =\sqrt{392} =19.79898987m\approx19.8m

The energy of an electromagnetic wave changes proportionally to which
ozzi

Answer:

D. Frequency

Explanation:

The energy of an  electromagnetic wave is proportional to frequency, mathematically it is expressed as;

E ∝ f

E = hf

where;

h is Planck's constant = 6.626 x 10⁻³⁴ Js

The equation above can also be expanded to;

E = hf = h \frac{c}{\lambda}

where;

c is speed of light = 3 x 10⁸ m/s

λ is the wavelength of the electromagnetic wave

Since the speed of light is constant, we can conclude that the energy of the electromagnetic wave is directly proportional to its frequency and inversely proportional to its wavelength.

Therefore, the correct option for direct proportionality is FREQUENCY
