The list of choices that you provided suggests profound silence, which is not too popular among scientists.
The product of (frequency) times (wavelength) is always
the same number (the speed of the wave).
So if the frequency is doubled, the wavelength has to drop to
half of what it was, in order to keep their product constant.
Answer:
Secondary current is 8A
Explanation:
Data :
Primary supply = Vp = 240 V
Secondary supply = Vs = 60V
Primary current = Ip = 2A
Secondary current = Is = ?
Formula : Vp × Ip = Vs × Is
So for secondary current formula becomes
Is = (Vp/Vs)×Ip = (240/60) × 2
Is = 4 × 2 = 8A
No. The forces of gravity between them would remain unchanged after those three changes.
Answer:
c(t)= 40t
Explanation:
As it forms the right angle triangle. see attachment for the figure.
We will use Pythagoras theorem i.e
a² + b² = c²
where,
'a' is perpendicular
'b' is base
'c' is hypotenuse i.e the distance D between the ships in terms of the time 't'
the distance 'a' from the starting point is 24t
the distance 'b' from the starting point is 32t
therefore,
(24t)²+ (32t)² = c(t)²
c(t)= √(24t)²+ (32t)²
c(t)= √576t² + 1024t²
c(t)=√ 1600t²
c(t)= 40t
Thus, function that models the distance D between the ships in terms of the time t (in hours) elapsed since their departure is 40t
