Answer:
1.319 × 10³ m/s
Explanation:
The formula for speed of sound is ;
v= f*λ where
v= speed of sound
f= frequency of sound= 3.705 kHz = 3705 Hz
λ= wavelength of sound = 35.6 cm = 0.356 m
Applying the formula ;
v= f*λ
v= 3705 * 0.356
v=1318.98 m/s
v= 1.319 × 10³ m/s
Answer:
t=0 is t
t=8= 8t
Explanation:
because 0 is means "nothing" so that's why t=0 is t
In short: Electromagnetic radiation is energy that is propagated in the form of electromagnetic waves
Best example of electromagnetic radiation is sunlight. Vsible light of sunlight is only a small portion of the EM spectrum. EM radiation is a form of energy that takes many forms, f.e.: microwaves, radiowaves, etc.
Answer:
B. The object reached terminal velocity.
Explanation:
At t=0.5, the acceleration is 0, so the velocity is constant. So the object has reached terminal velocity, and the net force is 0.
The type of ball is independent, as it doesn’t affect the experiment.
