The acceleration is 2 mph/min
Explanation:
The acceleration of an object is the rate of change of velocity. It is defined as follows:
where
v is the final velocity
u is the initial velocity
t is the time taken for the velocity to change from u to v
For the car in this problem, we have (taking North as positive direction):
u = 25 mph
v = 35 mph
t = 5 min
Substituting into the equation, we find the acceleration:

The navigation rules entail vessels restricted in their ability to maneuver to display appropriate flag or lights. During the day of engagement of vessel in diving activities the rigid replica of the international code flag "ALPHA" must be exhibit not less than 3.3 feet while during night time the vessel must display the navigation light which is red and white and this requirement does not affect divers red and white flag which may be required by state to mark a divers location. The "A" flag is a kind of navigational signal which indicates the vessel’s restricted maneuverability and do not pertain to diver.
Answer:
-3.2 ×1.6 ×10^-19C
Explanation:
Number of proton = 6
Number of electron = 8
To determine the quantity of the charge, we would first find the difference between the number of
protons and electrons. Then multiply the difference by charge 1.6 x 10 -19 C to determine the charge on the object.
Difference between proton and electron is elementary charge
Elementary charge = proton - electron
= 6 - 8
Elementary charge = -2e
Recall, charge (q) = 1.6 ×10^-19C
1e = 1.6 ×10^-19C
Magnitude of the charge of object = -2× (1.6 ×10^-19C)
Magnitude of the charge of object = -3.2 ×1.6 ×10^-19C
Waves and wind because wind can blow the rock or sand away and waves can wash is away
