Answer:
n = 18 cycles
Step-by-step explanation:
To know how many times does the current oscillates in the given time, you take into account that the number of oscillation can be calculated by using the following expression:
(1)
f: frequency of the oscillation of the current
t: time = 0.30s
The frequency is the number of cycles per second, that is, f = 60 cycles/s
You replace the values of f and t in the equation (1):
In 0.30s the current oscillates 18 times
Answer:
Step-by-step explanation:
this has bean simplifyed dow to
= -1/6
Triangle= 180 degrees
Angle = 37.5 degrees
Supplement angle = 105 degrees
If you multiply the angle (37.5) by 2 and then add 30, it gives you 105. Then add 37.5 twice to make up the other two angles of the triangle and it gives you 180 total degrees as a triangle should.

what's the question?..................
It's not often that you find rectangular prism-shaped rocks with these dimensions. Rather, we assume that the rock would fit into a box with the given dimensions, but not actually fill every corner of the box. The maximum possible volume of this rock would be (1.9 cm)(1.5 cm)(3.8 cm) = 10.83 cm^3; the actual volume is most likely less.
