The trait that a female alone would inherit would be certain hormones that are involved in reproduction. AND, for the obvious answer who some people just HAVE to mention, "Look in your pants and tell me what you see." I would also appreciate if you let my gender be unknown.
Answer:
Charge on the red box is -0.0033 C as it is attracting the blue box
Explanation:
As we know that two boxes are attracting each other
So here we can say that two boxes will have opposite charges
So as we know that electrostatic force between two charges is given as

here we have
here we know that


r = 4 m
F = 626 N


Answer: The height of the cloud = 394.55 m
Explanation:
The observer is 500m away from the spotlight.
Let x be the distance from the observer to the interception of the segment of the height, h with the floor. The equations are thus:
Tan 45° = h/x ... eq1
Tan 75° = h/(500- x ) ... eq2
From eq 1, Tan 45° = 1, therefore eq1 becomes:
h = x ... eq3
Put eq3 into eq2
Tan 75° = h/(500- h)
h = ( 500 - h ) Tan 75°
h = 500Tan 75° - hTan75°
h + h Tan 75° = 500 Tan 75°
h ( 1 + Tan 75° ) = 500 Tan75°
h = 500Tan75°/ (1 + Tan 75°)
h= 1866.02 / 4.73
h = 394.55m
Answer:
Δt = 0.315s
Explanation:
To calculate the time difference, in which both fans hear the batterstrike, you first calculate the time which takes the sound to travel the distances to both fans:


d1: distance to the first fan = 18.3 m
d2: distance to the second fan = 127 m
vs: speed of sound = 345 m/s
You replace the values of the parameters to calculate t1 and t2:

The difference in time will be:

Hence, the time difference between hearing the sound at the location s of both fans is 0.315s
I'm not sure, I think it's option A.
Let me know if I'm wrong!
