Answer:
Yes, it is accelerating
Explanation:
Acceleration is a vector quantity, which means it has both a magnitude and a direction.
Acceleration is defined as the rate of change of velocity:
where v is the velocity and t is the time.
v, the velocity, is also a vector, having both a magnitude (called speed) and a direction. This means that the acceleration is non-zero whenever the velocity is changing: this means that we have an acceleration either when the speed is changing, or also when the direction of the velocity is changing.
In the example in the question, the insect spins with the disc, so it is in circular motion. This means that the direction of the velocity of the insect is constantly changing: therefore, the acceleration of the insect is non-zero, so the insect is accelerating.

Answer:
Time = 0.58 seconds
Explanation:
Given the following data;
Initial momentum = 3 kgm/s
Final momentum = 10 kgm/s
Force = 12 N
To find the time required for the change in momentum;
First of all, we would determine the change in momentum.
Change in momentum = 7 kgm/s
Now, we can find the time required;
Note: the impulse of an object is equal to the change in momentum experienced by the object.
Mathematically, impulse (change in momentum) is given by the formula;
Making "time" the subject of formula, we have;
Substituting into the formula, we have;
Time = 0.58 seconds
Dendrites, the cell body, axon, terminal branches of the axon
Answer:
The correct answer is B-25 V
Explanation:
We apply Ohm's Law, according to which:
V = i x R
V = 5A x 5Ω
V= 25 V
Being V the potential difference whose unit is the VOLT, i the current intensity (Ampere) and R the electrical resistance (ohm)
