Anna litical is doing the it's all uphill lab. she applies a 13.8-newton force parallel to the inclined plane in order to pull a cart up a hill inclined at an angle of 51.6 degrees. if she drags the cart a distance of 138 cm, then how much work (in joules) does she do upon the cart?

The work(in Joules) is equal to 33.32.

Explanation:

F force can be considered here as a weight. Unit Joules is another name of Newton-meter that's why it is important to convert the given unit of distance from centimeters to meters.

Formula for work is W = f*sin(theta)*d

where,

f = force in Newton

d = distance in meters =(138-cm/100) = 1.38-meters

so we can get

W = 13.8*sin(51.6)*(1.38)

W = 33.32-Joules

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes

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.
