Answer:
The Mariana Trench is part of the Izu-Bonin-Mariana subduction system that forms the boundary between two tectonic plates. In this system, the western edge of one plate, the Pacific Plate, is subducted (i.e., thrust) beneath the smaller Mariana Plate that lies to the west.
Explanation:
Answer:
20 Hz, 20000 Hz
0.0166 m, 16.6 m
Explanation:
The minimum frequency that a human ear can hear is 20 Hz
The maximum frequency that a human ear can hear is 20000 Hz.
v = Velocity of sound = 332 m/s
Wavelength is given by
The longest wavelength that can be heard by the human ear is 16.6 m
The shortest wavelength that can be heard by the human ear is 0.0166 m.
Answer:
Explanation:
Let's solve your equation <em><u>step-by-step.</u></em>
()()=512
Step 1: <em>Simplify</em> both sides of the equation.
Step 2: <u><em>Divide </em></u>both sides by 4096.
=
Then you do that to get N = 1/8

7200 g is <span>equivalent to 7.2 kilograms</span>
Answer:
-0.4 m/s
Explanation:
We can solve this problem by using the law of conservation of momentum. In fact, the total momentum of the shell + cannon system must be conserved.
Before the shot, the total momentum of the system is zero:
p = 0
After the shot, the total momentum is:
where
m = 3.0 kg is the mass of the shell
v = 200 m/s is the velocity of the shell
M = 1500 kg is the mass of the cannon
V is the recoil velocity of the cannon
Since momentum is conserved, the initial and final momenta must be equal, therefore:
Where the negative sign indicates that the cannon moves in the opposite direction to the shell.
