Answer:

v = 800 m/s

Explanation:

Given that,

Distance, d = 2400 m

Time, t = 3 s

We need to find the velocity of a rocket. Distance covered per unit time equals velocity. So,

v=\dfrac{d}{t}\\\\v=\dfrac{2400\ m}{3\ s}\\\\v=800\ m/s

So, the velocity of the truck is 800 m/s.

Vaselesa [24]

Answer:

7.39 m or 3.61 m

Explanation:

\lambda = Wavelength

f = Frequency = 90 Hz

v = Speed of sound = 340 m/s

Path difference of the two waves is given by

s_1-s_2=\frac{\lambda}{2}

Velocity of wave

v=f\lambda\\\Rightarrow \lambda=\frac{v}{f}\\\Rightarrow \lambda=\frac{340}{90}\\\Rightarrow \lambda=3.78\ m

s_1=s_2\pm\frac{\lambda}{2}\\\Rightarrow s_1=5.5\pm \frac{3.78}{2}\\\Rightarrow s_1=7.39\ m, 3.61\ m

So, the location from the worker is 7.39 m or 3.61 m

julia-pushkina [17]
These are the characteristics that apply:

 - In a solution taste sour: which is consequence of the H+ concentration.

- Corrode metals: the H+ ion reacts with the metal producing a salt and water

-Produce hydronium ion in solution: as per the Bronsted - Lowry definition an acid is a substance that donates a proton, H+. This proton will react with H2O to form H3O+ (hydronium), as per this scheme: 

HA + H2O --> A(-) + H3O(+)
