Answer:
36
Step-by-step explanation:
Given that:
2 standard six sided dice are rolled :
Die 1 = 1, 2, 3, 4, 5, 6
Die 2 = 1, 2, 3, 4, 5, 6
Outcome = ordered pair of Number on the two dice
Event = different sum of the ordered pair of numbers.
The number of outcomes in the experiment = the sample space =) number of Faces)^number of dies
= 6^2
= 36 different outcomes

speed= distance/ time
1200km/0.006s= 200 000 km/s
<span>Question 4
</span>
wavelength = wavespeed / frequency
wavespeed = 16/8 = 2
Question 5
(400/60s) = 6.6667 waves/ sec (Hz).
<span>Velocity = 0.008m/sec. </span>
<span>Wavelength = (v/f) = 0.008/6.6667 = 0.0012 metre (1.2mm).
