Answer:
0.4 A
Explanation:
From the question,
Electric power = Voltage×current
P = VI.......................... Equation 1
Make I the subject of the equation
I = P/V..................... Equation 2
Given: P = 96 J/s, V = 230 V.
Substitute into equation 2
I = 96/230
I = 0.4 A.
Hence the current is 0.4 A
If the Earth's axis were closer to "straight up and down" than
the present 23.5°, then . . .
-- The areas around the north and south poles where the sun
can be up or down for more than 24 hours would be smaller.
-- The "Tropic Zone", between the Tropic of Cancer and the
Tropic of Capricorn, where it's possible for the sun to be
directly overhead, would be narrower.
-- There would be less difference, everywhere, between the
lengths of daylight on the "longest day" and the "shortest day"
of the year.
-- The seasons would be less extreme everywhere. There would
be less difference, everywhere, between the coldest part of the
Winter and the warmest part of the Summer.
Answer:
+1/3
Explanation:
The lens equation states that:
where
f is the focal length
p is the distance of the object from the lens
q is the distance of the image from the lens
For a diverging lens, the focal length is negative: 
and we also know that the object is placed a distance of twice the focal length, so 
So we can find q from the equation above
And the magnification of the image is given by
