Answer:
<em>The horizontal velocity vector of the canonball does not change at all, but is constant throughout the flight.</em>
Explanation:
First, I'll assume this is a projectile simulation, since no simulation is shown here. That been the case, in a projectile flight, there is only a vertical component force (gravity) acting on the body, and no horizontal component force on the body. The effect of this on the canonball is that the vertical velocity component on the canonball goes from maximum to zero at a deceleration of 9.81 m/s^2, in the first half of the flight. And then zero to maximum at an acceleration of 9.81 m/s^2 for the second half of the flight before hitting the ground. <em>Since there is no force acting on the horizontal velocity vector of the canonball, there will be no acceleration or deceleration of the horizontal velocity component of the canonball. This means that the horizontal velocity component of the canonball is constant throughout the flight</em>

Hello! Here are your answers!
SCALAR: Scalar quantities have a size or magnitude only.
VECTOR: Vector quantities have both magnitudes and direction.
Explanation:
They are alike as they are both used to explain physical quantities and represent the magnitudes or sizes of the physical quantities...
They are different as VECTOR quantities describe an objects DIRECTION as well as magnitude whilst SCALAR doesn't
ie...<u>SCALAR:</u> MASS, TIME
<u>VECTOR:</u> VELOCITY, ACCELERATION...
I HOPE THIS HELPS!!
Answer:
Explanation:
Neurons communicate via both electrical signals and chemical signals. The electrical signals are action potentials, which transmit the information from one of a neuron to the other; the chemical signals are neurotransmitters, which transmit the information from one neuron to the next.
The electrical signal travels down the axon to the axon terminals where it tells the vesicles to release the neurotransmitters into the synaptic cleft which travel to the receptors of the receiving cell which releases the second messengers
