He could spray the fire extinguisher in the opposite direction of the ship. This is definitely the answer because its all about momentum
I THINK that formula gives the vertical speed of a projectile at the time
't' seconds after it's launched.
(I can't really be sure of anything, because whenever you show a formula
to other people, you're supposed to tell them what each variable in it means,
and you didn't do that.)
If I'm on the right track, then the 'a' is the acceleration of gravity wherever
the projectile is flying. If that happens to be on Earth, then the acceleration
is 9.8 meters per second² .
As per the question there are three physical quantities named as position,distance and displacement.
Before coming into a conclusion first we have to understand a vector and a scalar.
A scalar quantity is a quantity which has only magnitude for it's complete specifications.
A vector is a quantity which has magnitude as well as direction and at the same time it is in accordance with the paraellogram law of vector addition.
Out of the three options displacement and position are vector quantities.It is because it is the minimum distance between two points .It has magnitude as well as direction.
Distance can not be considered as a vector quantity as it has only magnitude.There is no specific directions of distance travelled.
Position vector is a vector which provides location of an object in a plane or space.It is nothing else except the point which has x,y,z coordinates with origin is taken as the reference point.
Hence position and displacement are vectors
Answer:
Explanation:
Kirchoff's current law: It states that the total current entering at a junction is equal to the total current leaving at the junction. It isbased on conservation of charge.
As two current i1 and i2 is entering at the junction and i3 is leaving, so the current in forth wire is
i4 = i1 + i2 - i3
