Answer:
36 N
Explanation:
Velocity of a standing wave in a stretched string is:
v = √(T/ρ),
where T is the tension and ρ is the mass per unit length.
300 m/s = √(T / 4×10⁻⁴ kg/m)
T = 36 N
Answer:
Linear momentum= Mass*Velocity
P=mv
P=60*10
P=600Kg m/s
Answer:
There are no gaps in space between the photons as they travel. If you were to look at a wave then you'd come to a conclusion that indeed that there aren't any gaps unless they are specifically placed.The light from a distance star indeed spreads out and weakens as it travels, but this just reduces the wave strength and does not introduce gaps.

Explanation:
<u>Step 1: Define</u>
<em>Identify</em>
[Function] f(x) = 6x + 1.5
[Given] f(2.5) is <em>x</em> = 2.5 for function f(x)
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(2.5) = 6(2.5) + 1.5
- Multiply: f(2.5) = 15 + 1.5
- Add: f(2.5) = 16.5
