Dose mass alone determine weather an object will float or sink?
Inga [223]
If the density of the object is lower than the density of the liquid it is floating in then it will float. if the density is larger it will sink. density is mass/volume

Can you please help me with these physics displacement questions? If you can only do one, that is okay
Brut [27]

#3).  Your drawing in the lower right corner is correct.  You're headed down the right road, but ran out of gas and just stopped.

Radius of the circle = 1.5 km

Circumference of the whole circle = (2·π·radius) = 9.42 km

Distance = 3/4 of the way around it = 7.07 km .

Displacement = the straight line from the West point to the North point.  The straight-line length is 2.12 km; the straight-line direction from start to finish is Northeast (45°).  I'll let you figure out why these numbers.

#4).  What if you walk 1 mile East and then 1 mile West ?  You got a good workout, and you're back home where you started !  Your distance is 2 miles, and your displacement is zero.

The whale had a good workout too.  She swam (6.9 + 1.8 + 3.7) = 12.4 km.  She's sweating and tired.  Her total distance during that workout is 12.4 km.  

Her displacement is the line from start-point to end-point.  How she got there doesn't matter, so swimming 1 km East and then swimming 1 km West cancel out, and have no effect on the displacement.

(6.9E + 1.8W + 3.7E)  =  (10.6 E) + (1.8 W) . . . That adds up to  8.8 East !  That's where she ends up.  That's her displacement ... 8.8 km East of where she started.  Since we're only talking about displacement, we don't care HOW she got there.  She might have been swimming big 20-km circles all day.  We don't know.  All we know is that she ended up 8.8 km East of where she started.

How does radiation transfer thermal energy from the Sun to Earth?
Svetradugi [14.3K]

Answer:

The thermal energy is carried by electromagnetic waves

Explanation:

There are three types of transfer of heat (thermal energy):

- Conduction: conduction occurs when two objects/two substances are in contact with each other. The heat is transferred from the hotter object to the colder object by the collisions between the molecules of the two mediums.

- Convection: convection occurs when a fluid is heated by an external source of heat. The part of the fluid closer to the heat source gets warmer, therefore it becomes less dense and it rises, and it is replaced by the colder part of the fluid, which is colder. Then, this part of fluid is heated as well, so it gets warmer, it rises, etc.. in a cycle.

- Radiation: radiation occurs when thermal energy is carried by electromagnetic waves. Since electromagnetic waves do not need a medium to propagate, this is the only method of heat transfer that can occur through a vacuum (so, in space as well).

Indeed, the Sun emits a lot of electromagnetic radiation, which travels through space and eventually reaches the Earth, heating it.
