Frequency= speed/ wavelength
=0.5m/s divided 0.1.m
=5.0 Hz
The answer would be letter D.
Answer:
Explanation:
As we know that the tension in two strings are
now we have
so we can say
also we have
now divide two equations
Answer:
<u>40 m/s</u>
Explanation:
The final velocity of an object that experiences a period of acceleration is given by:
v - vi = A*t
Initial velocity, vi, is = 20m/s
Acceleration, A, is 4m/2^2
Time, t, is 5 seconds
v - vi = A*t
v - 20m/s = (4m/2^2)/(5 sec)
v = (20 m/s) + (20 m/s)
v = 40 m/s
Answer:
The final velocity of the vehicles will be -75km per hour (leftwards).
Explanation:
Let us call , mass and velocity of the truck , mass and velocity of the car, and the final velocity of the vehicles.
The law of conservation of momentum states that
solving for we get:
putting in numerical values
(<em>the negative sign indicates that the vehicles are moving in the leftward direction)</em>
or -75.8 km per hour.<em> </em>
Glucose is blood sugar (hyperglycemia) comes from diabeties often, but can occur with other reasons, when glucose is to high someoenes sugar raises. Often this can lead to a diabetic coma, fatigue, vomiting, hospitalization, and even death if serious enough, from to high sugar. Many things can happen after this, and a lot are serious.
on the flip side (hypoglycemia) if sugar gets to low, confusion, fainting, vomiting, and nausea occur, as well as comas, and death if serious enought.
