Aluxury liner has a diesel-electric powerplant with a maximum power of 83 mw at a cruising speed of 39.4 knots. what forward force is exerted on the ship at this speed?

4.09 MN

Explanation:

P(max) = 83 MW

Speed = 39.4 knots

1 knot = 1.852 km/h

Speed in km/h = 39.4 * 1.852

= 72.9688 km/h

= (72.9688*1000) / 3600

= 20.27 m/s

The exerted force is F

P = Fv

P = |F| |v| cos α

P = |F| * 20.27cos 0

P = 20.27F

F = (83 *10^6)/20.27

F = 4.09 * 10^6

F = 4.09MN

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
