Basic truss bridge types found in North Carolina (source: HAER) A truss bridge can be characterized by the location of its traffic deck. At a pony truss, the travel surface passes along the bottom chords of trusses standing to either side that are not connected to each other at the top.
Answer:
Depends on the capacity of battery. Mostly our phones flashlight can be used up to 8 to 10hrs continuosly
Explanation:
Capacity of the battery is level to which battery is charged, & amount of current drawn by the flashlight, you can calculate the answer yourself if u know the capacity of that light.
Moreover you can calculate this by using equation,
E =Pt
So, for time
t=E/P
Batteries are rated in Amp hours, like 10 amp hours will supply us 1 amp for 10 hours
2 amps will give us 5 hours

Answer:
λ₂ = 1.8 m
Explanation:
given,
wavelength of the string 1 = 0.90 m
frequency of the string 1 = 600 Hz
wavelength of string 2 = ?
frequency of the string 2 = 300 Hz
we now,
now,
λ₂ = 2 x 0.9
λ₂ = 1.8 m
Hence, the wavelength of the second string is equal to λ₂ = 1.8 m

Centripetal force is modeled by the equation:
F = MV^2/R
where
F = force
M = Mass
V = Velocity
R = Radius
I will assume the shark is swimming in a circle with a radius of 14 m / 2 = 7 m. The actual radius will be smaller, but I'll assume that the question is simply poorly worded. So we need to calculate the velocity of the shark. The circumference of the circle is pi*14m = 43.98229715 m. And since velocity is defined as distance over time, we have a velocity of 43.98229715 m / 80 s = 0.549778714 m/s.
Now substitute the known values into the equation for centripetal force.
F = MV^2/R
F = 681 kg * ( 0.549778714 m/s)^2 / 7m
F = 681 kg * 0.302256635 m^2/s^2 / 7m
F = 205.8367683 kg*m^2/s^2 / 7m
F = 29.40525261 kg*m/s^2
F = 29.40525261 N
Rounding to 2 significant figures gives a force of 29 Newtons.</span>
