Exothermic is the answer to your question
Answer:
Install sound absorbers such as foam or acoustical panels
Explanation:
They could install some sound absorbers such as foam or acoustical panels in the walls, floors, and ceiling of the conference room.
The nucleus is a Negative charge I believe
Answer:
The total resistance is 5000 N. So the net force left for acceleration is 7 000 N (12 000 - 5 000).
7000 N applied to 2x700 kg gives a maximum acceleration of
a = F/m = 7000/1400kg = 5 m/s^2
At 5m/s^2, it will take 8 s to reach 40 m/s. In 8 second the distance covered will be
d = 1/2 at^2 = 1/2 x 5 x 8^2 = 160 m
Because each glider has the same drag and inertia, the tension in the rope between the gliders will be exactly half of the tension between plane and the two gliders:
12 000/2 = 6 000N.
Answer:
The wavelength of the 320 Hz sound waves in the column of air is 1070 mm.
Explanation:
To solve the question, we note that the tube acts as a pipe with one end closed and that a stationary wave is formed in the tube from the top, to the bottom of the tube and back.
The simplest and the first wave form in the tube has length L = Lambda/4
That is, a node at the closed end and an antinode at the open end
The second stationary wave is given by
l + 535 mm= 3/4×lambda
However v = f×lambda
f = v/lambda = v/(4l)
Therefore
Lambda/4 + 535 mm = 3/4lambda
Or 535 mm = 3/4lambda -Lambda/4 = lambda/2
Therefore, lambda = 2×535 mm = 1070 mm
The wavelength = 1070 mm
