How is Venus similar to Earth?
2 answers:
Answer: D
Explanation: I have my answers VS. Go0gle answers (go0gle answers are pics)
(A) Both have the same day length. Well, Venus doesn't havve the same amount of days. (I already know off the top of my head, but I still searched it up)
(B) Both rotate in the same direction. In school (before Virus) they would always show diagrams of the planets on the projector and Venus doesn't rotate
(C) Both have ample water. No. Venus doesn't have much water >_>
(D) Both have a solid inner core and a liquid outer core. Yesh. In my lessons (before), Venus has a solid inner core and liquid outer core.

For a point charge, how does the potential vary with distance from the point charge, r?
a constant
b. r.
c. 1/r.
d. .
e. .
Answer:
The correct option is C
Explanation:
Generally for a point charge the electric potential is mathematically represented as
Here we can deduce that the electric potential varies inversely with the distance i.e
So
Answer:
Explanation:
a. Given that:
mass of first & second piece,
mass of 3rd piece,
-velocity of first piece(
) and
as velocity of 2nd piece (
)
Let be velocity of 3rd piece=?
#Vessel is at rest before explosion. Considering conservation of linear momentum:
#Dividing both sides by
#Plug the values:
#So the magnitude of the third piece is:
Magnitude of the 3rd piece is 10.84 m/s
b. To find direction of the magnitude (as an angle relative to the -axis), we find
. The angle is obtained by getting the tan inverse as:
-The direction of the magnitude (angle relative to the x-axis) is 45°
