The Answer is A, the iris dilates the pupil.
Answer:
Time taken to stop = 6 sec
Explanation:
Given:
Rotation of wheel = 1.10 × 10² rev/min
Final velocity (v) = 0
Angular acceleration (a) = - 1.92 rad/s²
Find:
Time taken to stop
Computation:
Initial velocity (u) = (1.10 × 10² × 2π rad) / 60 sec
Initial velocity (u) = 11.52 rad / sec
We know that,
V = U +at
t = (v-u)a
t = (0 - 11.52) / (-1.92)
Time taken to stop = 6 sec
The correct answer is "wavelength".
In fact, this is exactly the definition of wavelength: in a wave, the wavelength is defined as the distance between two succesive crests or two successive troughs, therefore the correct answer is
D) wavelength.
Answer:
1st one goes to the first one the second one goes to the first one the thired one goes to the second one the forth one goes to the second one and the fifth one goes to the first one.
Explanation:
Answer:
8 mph, 12 mph
Explanation:
t = Time taken = 7 hours
x = Speed of Randall
x+4 = Speed of Gregory
The distance they both will travel together is 140 miles if they start at the same time.
The speed of Randall is 8 mph
The speed of Gregory is 8+4 = 12 mph
