To solve this problem we will apply the linear motion kinematic equations. First we will determine the time it takes for the camera to fall to the floor. Later with that time, we will calculate from the initial position when the balloon ascended.

Here
= Initial velocity
g= Acceleration due to gravity
t = time
Replacing with our values

Solving for the time,

Now with the previous position we have that the balloon has ascended around to,



(a). Models are not totally inclusive, that is they do not contain all the possible data about an object. (b). Approximations are normally used, since these are not exact, different results may be observed for real events and model events. (c). Loss of accuracy as a result of over simplification.
Answer:
(2) the work required to move the electron is 4.8 x 10⁻¹⁹ J.
Explanation:
Given;
potential difference, V = 3.00 volts
charge of electron, q = 1.6 x 10⁻¹⁹ C
The work required to move an electron is calculated as;
W = Vq
where;
W is the work done in Joules
Substitute the given values and solve for W;
W = (3.00)(1.6 x 10⁻¹⁹)
W = 4.8 x 10⁻¹⁹ J.
Therefore, the work required to move the electron is 4.8 x 10⁻¹⁹ J.
Answer:
Directional hypothesis is an example of a directional research hypothesis.
Explanation:
Directional hypothesis: A directional (or one tailed hypothesis) states which way you think the results are going to go, for example in an experimental study we might say…”Participants who have been deprived of sleep for 24 hours will have more cold symptoms in the following week after exposure to a virus than
