Answer:
Vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude. Although a vector has magnitude and direction, it does not have position.
Explanation:
The only thing I found in my notes for this question was this although it isn't in your choices, I just hope this helps you and hope you get it right!
In a food pyramid, the organism that has the least amount of total energy available is the one that is in the bottom or last. In this case, given the list of organisms above, the organism that would have the least amount of total energy available would be the RED FOX. The answer is option A. Hope this answer helps.
Answer:
The bullet that is fired will spend longer in the air, hitting the ground after the dropped bullet.
Explanation:
Using the equation: x
= x
0 +
v
t
If we neglect the effects of air resistance, the horizontal motion is a constant velocity.
The horizontal displacement = (velocity X cosθ)
So, the fired bullet has to travel horizontally before falling which takes a longer time compared to a bullet dropped where it is, height = 1/2 gt^2
gravity, g = 9.8 m/s2.
Answer:
J=0.211kg.m/s
Explanation:
The impulse-momentum theorem states:
The velocity before the impact is given by:
For the velocity after the impact:
so:
Answer:
21/5 seconds or 4.2 seconds
Explanation:
Distance=Speed*Time
21=5 *Time
21/5=Time
4.2=time
