A boat moves 60 kilometers east from point A to point B. There, it reverses direction and travels another 45 kilometers toward p
Alexxx [7]

Answer:1) the total distance is the sum of the two distances

60 km +  45 km = 105 km

2) The displacement is the net movement, or the difference between the initial position and the final position

Call x the initial position, then the final position is x + [60km - 45km]

And the displacement is x + (60km - 45km) - x =60km -45 km = 15 km

How does the orbital speed of an asteroid in a circular solar orbit with a radius of 4.0 AU compare to a circular solar orbit wi
Murrr4er [49]

Answer:

The circular solar orbital speed at 4.0AU is 1/4( one fourth) that at 1.0AU

Explanation:

am = mvr= angular momentum

am4= 4mvt

am1= mvp1

Vt=1/4vp

Vp=4vt

am1= 4mvt

am1=am4

The circular solar orbital speed at 4.0AU is 1/4 (one fourth) that at 1.0AU

tiny-mole [99]

Answer:

=8.0 Watts

Explanation:

Power is a ratio of work done over time. The power in an electric circuit is calculated using the following formula:

P=I²R

P is power, I is  current, R is resistance

Therefore,  Power= 4²ₓ 0.5Ω

=8.0 Watts
