Answer:
Unbalanced forces is the correct answer.
Explanation:
In spring mass system we know that angular frequency is given as
f = 8.38 Hz
now we know that speed of SHM at its extreme position is given by
here we know that
A = 17.5 cm
so maximum speed is 9.21 m/s
Rinse Bacon in Water Before Cooking to Reduce Shrinkage by 50 Percent. This sounds like a bizarre thing to do, but we're talking about less bacon shrinkage! Rinse your… At the end of the day, the best way to keep your bacon from shrinking when cooking is to cook it low and slow in the oven.
Answer:
Explanation:
We shall apply Doppler's effect of sound .
speaker is the source , Jason is the observer . Source is moving at 10 m /s , observer is moving at 6 m/s .
apparent frequency =
V is velocity of sound , v₀ is velocity of observer and v_s is velocity of source and f_o is real frequency of source .
Here V = 340 m/s , v₀ is 6 m/s , v_s is 10 m/s . f_o = f
apparent frequency =
=
So m = 346 , n = 330 .
A scalar quantity is a measurement of a quantity, like temperature, or mass.
