Answer:
C. Both A and B
Explanation:
<em>Electronic leveling systems: </em>These are automatic lifting jacks use for raising wheels and vehicle when parked or when work is to be done on the vehicle engine underneath or on wheels. unlike the manual jacks it is very quick and efficient.
Both technician right, for Technician A, a weight may be use during the procedure for balancing and leveling when raising, and for Technician B, the sensor in the electronic leveling systems is adjustable to adjust the height so as to maintain balancing and levelling.
Answer:
45000kgm/s due east
Explanation:
Given parameters:
Mass of the car = 1.5 x 10³kg
Velocity = 30m/s
Time taken = 60s
Unknown:
Momentum = ?
Solution:
Momentum is the quantity of motion a body possess,
Momentum = mass x velocity
So;
Momentum = 1.5 x 10³ x 30 = 45000kgm/s due east

Answer:
8.6 miles
Explanation:
In order to calculate the straight-line distance between the starting point and the ending point, we need to resolve each part of the displacement into two perpendicular directions, let's say horizontal (x) and vertical (y) directions.
In the first part, Erica moves for 5.2 miles 25∘ north of east. Resolving into the two directions:
In the second part, Erica moves 5.0 miles north, so the components are
So the components of the net displacement are
And the magnitude of the net displacement is
