The Pacific Plate is moving 29 mm/year toward the north and 20 mm/year toward the west relative to the North American Plate. Sho
adell [148]

Answer:

7 mm per year

Explanation:

It is given that :

The Pacific plate is moving towards north at = 29 mm per year

The Pacific plate is moving towards west at = 20 mm per year

We have to calculate the total relative motion towards the northwest.

So we have to find the resultant of the two motions.

Since the two movements are perpendicular, therefore the angle between the two motions is 90 degree.

Therefore, finding their resultant,

R^2=(29)^2+(20)^2

R^2=(49)^2

R = 7

Therefore, total relative motion towards the northwest is 7 mm per year.

A vehicle moves in a straight line with an acceleration of 4 km/h2. By how much does the speed change each second? Answer in uni
Elena-2011 [213]

Answer:

The speed of the vehicle changes in each second is, v = 0.00111 Km/h

Explanation:

Given,

The acceleration of the vehicle, a = 4 Km/h²

Converting it into m/s,

                                                    a = 0.0003086 m/s²

In each second the vehicle covers 0.0003086 m

The speed of the vehicle in each second is given by 0.0003086 m/s

Converting it into Km/h

                                     v = 0.00111 Km/h

Therefore, the speed of the vehicle changes in each second is, v = 0.00111 Km/h
