Answer:

0.21632 m

Explanation:

f = Frequency = 260 Hz

\lambda = Wavelength = 0.6 m

v = Velocity = f\lambda

T = Tension = 225 N

m = Mass of string = 2\times 10^{-3}\ kg

L = Length of string

Velocity of wave is given by

v=\sqrt{\dfrac{T}{m/L}}\\\Rightarrow L=\dfrac{v^2m}{T}\\\Rightarrow L=\dfrac{(260\times 0.6)^2\times 2\times 10^{-3}}{225}\\\Rightarrow L=0.21632\ m

The length of the string is 0.21632 m

tino4ka555 [31]

Answer:

The Starship Enterprise is powered by combining matter with antimatter. Suppose 1 kg of each are combined and ejected backward at the speed of light, what is the final speed of the Enterprise starting from rest? Assume that the mass of the Enterprise is 10,000 kg and the spaceship does not reach relativistic speed.

You are in Paris, 60 m up in the Eiffel Tower. If you throw a euro downward at a velocity of 2.0 m/s, how long would it take the
kondor19780726 [428]

Answer:

t = 3.29 seconds

Explanation:

It is given that,

Height of the Eiffel tower is 60 m

Initial speed of a euro, u = 2 m/s

It will move under the action of gravity in the downward direction. Firstly, we can find the final velocity as follows :

v^2-u^2=2ad\\\\v=\sqrt{u^2+2ad} \\\\v=\sqrt{(2)^2+2\times 9.81\times 60} \\\\v=34.36\ m/s

Let t is the time taken by the euro to hit the ground. It can be calculated as :

v=u+at\\\\t=\dfrac{v-u}{a}\\\\t=\dfrac{34.36-2}{9.81}\\\\t=3.29\ s

Hence, it will take 3.29 seconds to hit the ground.
