Answer:
The question is incomplete,
the displacement time graph is missing. Check attachment for the graph.
Explanation:
Average velocity can be find by using
Average velocity = change in displacement / time taken
A.V = ∆y / ∆t
So, at time t1 = 4s, the position of the body is at 2m
y1 = 2m
Also, at time t2 = 10s, the position of the body is at 5m
y2 = 5m.
So,
A.V = ∆y / ∆t
A.V = (y2 - y1) / (t2 - t1)
A.V = (5 - 2) / (10 - 4)
A.V = 3 / 6
A.V = 0.5m/s
So, the average velocity is 0.5m/s
It is when two atoms, or more, make a chemical bond by sharing atoms, using them together to get full energy levels. They do this instead of just taking electrons.
The pressure inside the plant cell is turgor pressure and it is also controlled by osmosis which is movement of molecule from higher to lower concentration across a membrane that is selectively permeable
The opening and closing of stomata also control turgor pressure

Answer:
C. greater than D, but less than 2D
Explanation:
The amount of potential energy in the system is a function of the compression of the spring. That is the same for both masses.
The potential energy is transferred to kinetic energy when the spring is released. The kinetic energy is jointly proportional to the mass and the square of the velocity. That is, the velocity is inversely proportional to the square root of the mass, for the same kinetic energy.
The horizontal distance traveled will be proportional to the launch velocity. So a halving of the mass will increase the velocity by a factor of ...
v2 = v1·√(1/(1/2)) = v1·√2
This means the second mass will land at a distance of about D√2, a value ...
greater than D but less than 2D.
