Answer:
longitudinal wave
Explanation:
make it to the brainiest answer
Explanation:
The frequency of an organ pipe if it is open is given by :
v is speed of sound in air is 343 m/s at 20°C
For fundamental frequency, n = 1
First overtone frequency,
Second overtone frequency,
Third overtone frequency
Hence, this is the required solution.
1 newton per square meter = 1 pascal of pressure.
The largest face of the brick is (0.19 x 0.095) = .01805 square meter
25N/0.01805 = 1,385 newtons per square meter = 1,385 pascal = 1.385 kPa
A)
Atmospheric pressure is 101325 Pa.
Pressure = Force / Area
Area of table = 1.5 x 2.2
= 3.3 m²
Force = 101325 x 3.3
= 334 kN
B)
According to Newton's third law, every action has an equal and opposite reaction. Thus, the upward force is equal to the force acting downward on the table and is being balanced. The force is 334 kN in the upward direction.
The heavier the object the faster it will fall. The lighter the object the slower to fall. You can test this for example with a rock and a piece of paper. The paper will take more time to for it to hit the ground rather than the rock which will be quicker.
