A car travels 30 km north in 25 min. and 40 km east in 35 min. What is the total distance traveled?10 km
50 km
70 km
cannot be determined

Answers

Answer:

The answer is 70 km

Explanation:

Firstly, there are few facts that we have to know:

The car travels northward and then eastward, so both direction are perpendicular.
It doesn't matter the total time, because we already know the total distance in every direction.
The question is about distance, NOT displacement. I have attached an image that shows the difference between both concepts.

Finally, the first 25 min the car traveled in total 30 km and after that, the car traveled in total 40 km during 35 min. So, the total distance is:

30+40=70 km.

Correct answer is 70 KM.

Which of the following is the best example of a compression force?a. dragging a rope to move a sled
b. the force of weight on a bicycle
c. typing the computer key for the letter y
d. the force of a picture hanging on a nail

Answers

The best example of a compression force is the force of weight on a bicycle. The answer is letter B. A compression force is when the weight of the bicycle imposes a downward force to the ground and the ground imposes an upward force to the bicycle.

I took the test and got B) the force of weight on a bicycle correct

The wavelengths for visible light rays correspond to which of these optionsA. About the size of a pen
B. About the size of a virus or large molecule
C. About the size of an amoeba
D. Smaller than an atom
E. About the size of a football field

Answers

So we want to know what does the wavelength of vidible light corresponds to. So the wavelength of visible light is around 400 - 700 nm or 400*10^-9 m to 700*10^-9 m. Virus size is around 20 - 400 nm. Large moleculer are around 100 nm to 200 nm. Atoms are around 10^-10 m and all the other options are too large. So the correct answer is B.

exportation.
civil war.
dictatorships.

Answers

Starvation is the result of amal-distribution of food, which is primarily due to drought and of course, alack of resources. From the choices above, of course dictatorships, which isexploiting the citizens’ natural resources for one’s own tyrannical benefit maylead to lack of resources. Civil war, will not only cause casualties but lackof resources as well. As well as too much exportation of resources leavingnothing for the country. The point is, everything will cause lack of resourcesbut lack of resources is the root cause of starvation where the demands of thepeople are greater than the supply.

a skier is gliding along 3.0 m/s on horizontal, frictionless snow. he suddenly starts down a 10 degrees incline. his speed at the bottom is 15 m/s. what is the lenght of the incline? how long does it take him to reach the bottom?

Answers

... find length
(way 1) determine acceleration using force
only force act on skier is mg vertically. spilt vector we get force along the incline = mgsin(10) and f= ma so
ma = mgsin(10) or a = gsin(10)
a (along the incline)= gsin(10) = 10sin(10) = 1.74
v^2 = u^2 + 2as
15^2 = 3^2 + 2(1.74)s
s = 62.06 m

(way 2) using conservation of energy
energy (KE+PE) on top = energy at bottom
0.5m3^2 + mgh = 0.5m15^2 +0
h (height of incline) = (112.5 - 4.5)/10 = 19.8 m
length of incline = h/sin(10) = 62.2 m ; trigonometry

... find time
s = (u+v)t/2
t = 2s/(u+v) = 2(62.2)/(3+15) = 6.91 s
