Answer:
Explanation:
A general wave function is given by:
A: amplitude of the wave = 0.075m
k: wave number
w: angular frequency
a) You use the following expressions for the calculation of k, w, T and λ:
b) Hence, the wave function is:
c) for x=3m you have:
d) the speed of the medium:
you can see the velocity of the medium for example for x = 0:
<span>(a) 0.0676 l
(b) 67.6 cc
So we've been told that 5.00 L of blood flows through the heart every minute and that the heart beats 74.0 times per minute. So that means that for every beat of the heart, 5.00 L / 74.0 = 0.067567568 L of blood flows through the heart. Rounding to 3 significant figures gives 0.0676 l. Converting from liters to cubic centimeters simply require a multiplication by 1000, so we have 67.6 cc of blood pumped per beat.</span>
How do catalysts speed up reactions ?
by reducing the amount of energy required for the reaction to occur. other factors such as <span>catalysts' ability to speed a process are temperature, concentration </span>
It will be a red giant for about 5 billion years
Answer:
(av + bu) miles
Explanation:
Average speed = distance/time
distance = time × average speed
distance from the starting point to the beginning of the opposite direction = a hours × v mph (mph is miles per hour) = av miles
distance from the opposite direction to the end = b hours × u mph = bu miles
distance from where he started to the end = (av + bu) miles
