Answer:
The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days
Answer:

Explanation:
Impulse-momentum theorem states that impulse is equal to the change of momentum:
(1)
with pf the final momentum and pi the initial momentum. Knowing that momentum is mass (m) times velocity (1) is:

It's important to note that we're dealing with vector quantities so direction matters. If we choose towards the floor positive direction then the initial velocity is positive and the final velocity is negative, so:


So, the impulse delivered to the floor is

The example of electric force in the given question is a Plastic wrap sticks to glass bowl containing leftovers. Option A is the right answer.
ELECTRIC FORCE
According to Coulomb's law, the electric force is proportional to the product of the charges and inversely proportional to the square of the distance between them.
The electric force can be:
The electric force can be exhibited in both static and current electricity. Example of static electricity are;
- an ebonite rod rub with silk.
The example of electric force in the given question is a Plastic wrap sticks to glass bowl containing leftovers.
The plastic wrap is able to stick to glass bowl container because of the force of attraction between the plastic wrap and the glass bowl container.
Therefore, the correct answer is the option A

Since car is accelerating uniformly that means we it is accelerating at constant rate if you can say that way. To find its acceleration all we have to do is find difference between v1=13 m/s and v2 = 25m/s and divide it by interval that car is taking to accelerate.
a = (v2-v1)/t = 2,4m/s^2
since car is accelerating at constat rate and truck covers same distance as car needs to accelerate from 13 to 25m that means that we can say that in that period truck travelled at cars average speed.
Vtruck = (v1 + v2)/2 = 19m/s
