Answer:
Particles of matter are packed more tightly in the ground than in the air
Explanation:
the reason is that sound waves are vibrations of the molecules of the medium: therefore, if the particles of the medium are closer together (as in solids), the vibrations can be transmitted faster, and the wave can travel faster
The answer is "Conduct an experiment" :)
Drag Force = bv^2 = ma; a = g = 9.81 m/s^2
b = mg/v^2 = (0.0023×9.81)/(9.4^2)
b = 0.000255
The law of Bio Savart is used to show the magnetic intensity because of the availability of magnetic current.
<u>Explanation:</u>
In physics, explicitly electromagnetism, the Biot–Savart law is a condition portraying the attractive field produced by a consistent electric flow. It relates the attractive field to the extent, heading, length, and closeness of the electric flow.
The Biot Savart Law expresses that it is a scientific articulation which shows the attractive field delivered by a steady electric flow in the specific electromagnetism of material science. It tells the attractive field toward the greatness, length, heading, just as closeness of the electric flow.
Answer:
86.3m/s
Explanation:
Given parameters:
Height = 380m
Unknown:
Final velocity = ?
Solution:
To solve this problem, we use one of the kinematic equations.
V² = U² + 2gH
V is the final velocity
U is the initial velocity = 0m/s
g is the acceleration due to gravity
H is the height
V² = 0² + (2 x 9.8 x 380) = 7448
V = 86.3m/s
