Heya!!
For calculate wavelength, lets applicate formula:
<u>Δ Being Δ</u>
f = Frequency = 262 Hz
v = Velocity = 343 m/s
= Wavelenght = ?
⇒ Let's replace according the formula:
⇒ Resolving
Result:
The wavelength is <u>1,3 meters.</u>
Good Luck!!
Answer:
V2 = 1.33m/s
Explanation:
M1 = 30 ton
M2 = 90 ton
V1 = 4 m/s
V2 = ?
Assumption: momentum conserved, no friction
initial momentum = final momentum = 0
momentum : p = MV
(M1*V1) - (M2*V2) = 0
V2 = (30*4)/90 = 1.33m/s
It's a virtual force ... one that seems to be there but isn't really there.
When something tries to fly or flow straight, through a rotating neighborhood, it ends up flying or flowing in a curved path, AS IF there were a force acting on it to make it curve. THAT apparent force is the Coriolis force.
It's what makes air, flowing away from high pressure or into low pressure, form the big rotating pressure systems on the rotating Earth.
Answer:
Explanation:
<u>Average Speed
</u>
If an object travels a distance d in a time t regardless of the direction, the average speed is the quotient of the distance over the time:
It's known a person runs d=15 kilometers in t=2 hours, thus his/her average speed is:
Calculating:
It's a simple linear equation in ' k ' .
Its solution is k=8 .
