acting on the box. (b) How would the diagram change if the box were sliding down the plane. (c) How
would it change if the box were sliding up the plane after an initial shove?
(a) The free body of all the forces include, frictional force, weight of the box acting perpendicular and another acting parallel to the plane.
(b) When the box is sliding down, the frictional force acts towards the right.

Geography (geo-gra-phy)Location (lo-ca-tion)Coordinates (co-or-di-nates)Landmass (land-mass)Absolute (ab-so-lute)Vicinal (vi-ci-nal)Insular (in-su-lar)Relative (re-la-tive)Note: It's very likely the tile labeled "MAL" should be "NAL", and that "MATES" should be "NATES".
==================================
Explanations:
Geography deals with not only places, but also the people and cultures in those places. That's more of a social or human geography course. Natural geography talks about land formations, volcanos, rivers, etc.I'm not sure there's much to say about this term. It's simply a position in 2D or 3D space depending on context.Coordinates are things like longitude and latitude. Think of the (x,y) points on a grid. Side note: The tile "mates" should be labeled as "nates". Your teacher made a typo. In some dialects, the "co" and "or" are pronounced together; almost sounding like "core". The term "landmass" is exactly what you'd expect it should be: a big chunk of land. When you mention if a person has absolute freedom, then we consider that person having no restrictions of movement/choice/etc. It also refers to something like a local coordinate space talks about the surrounding area, whereas an absolute coordinate space doesn't have to worry about such issues. Eg: a local coordinate could be "go 5 blocks from the store" and an absolute coordinate would be to provide a GPS location. As you can see, the local coordinate space needs the store as an anchor or else it wouldn't make much sense.To be quite honest, I had a bit of a long time to find this answer. I suppose if you are good with words then it shouldn't be too much of a struggle. But I did a reverse dictionary lookup and only focused on three syllable words until I arrived at "vicinal" which is related to "vicinity". Eg: The person was just in the vicinity. Anyways, I haven't really seen this word used too much in everyday language, so that's probably why it took a while for me. I have a feeling your teacher meant to write "NAL" instead of "MAL" as one of the tiles. This appears to be the second time s/he mixed up M's with N's (the first time being "MATES" mixed up with "NATES"; see problem 3). Insular is an adjective referring to a person or group of people cut off from the larger world. Think of a small town where it's hard to reach. Islands are of course like this, but we could have an "island" rural small town or some culture in a remote location that is on a continent somewhere. It doesn't necessarily have to be a literal island surrounded by water. Think of the word "insulate" to help remember "insular". Also, the term "insular" could refer to the deliberate attempt to keep oneself (or one group) closed off from the rest of the world. An example of this is the Amish culture being insular to the American culture surrounding them. If object A is larger than object B, then we say A is relatively large compared to B. This is one example usage of the word "relative".what makes urban heat island worse and what effects it and how can it be reduced?
Answer:
Extreme heat events often affect our most vulnerable populations first. Trees, green roofs, and vegetation can help reduce urban heat island effects by shading building surfaces, deflecting radiation from the sun, and releasing moisture into the atmosphere.

Explain how radiation takes place
Answer:
Heat transfer through radiation takes place in the form of electromagnetic waves, mainly in the infrared region. The radiation is emitted by some body as a consequence of the thermal agitation of its composing molecules.
Explanation:
The transfer of heat by radiation involves the carrying of energy from an origin to the space surrounding it. The energy is carried by electromagnetic waves and does not involve the movement or the interaction of matter.

For how long must an object travel at 29.8 km/s to cover 940 Gm?
Answer:
For how long must an object travel at 29.8km/s to cover 940Gm? t = 940 Gm 29.8 km/s = 940 ⋅ 1 0 9 m 29.8 ⋅ 1 0 3 m s = 9.4 ⋅ 1 0 11 m 2.98 ⋅ 1 0 4 m s ≈ 3.154 ⋅ 1 0 7 s .
Explanation:
It will take 3,15,43,674 sec to cover a distance of 940 Gm with a speed of 29.8 km/s.
How are speed, distance and time interrelated?
Speed [s], distance [d] and time [t] are related to each other by the following relation -
s = d/t
Given is an object travelling at 29.8 km/s in order to cover 940 Gm.
In 1 Gm(Gigameter) there are 1000000000 m or 10⁹ m
Speed of object [s] = 29.8 km/s = 29800 m/s.
Distance to be covered [d] = 940 x 10⁹ m
Time taken to cover the distance of 1 Gm will be -
t = 1 Gm / 29800
t = (10⁷ x 100) / 29800
t = 10⁷/ 298
t = 33557.1 seconds
Therefore, in order to travel 940 Gm, it will take -
940 x 33557.1 = 3,15,43,674 sec
Therefore, it will take 3,15,43,674 sec to cover a distance of 940 Gm with a speed of 29.8 km/s.

A 71 kg hiker climbs to the top of a 4300 m -high mountain. The climb is made in 5. 5 h starting at an elevation of 2800 m. Calculate the work done by the hiker against gravity. Calculate the average power output in watts. Calculate the average power output in horsepower. Calculate assuming the body is 16% efficient, what rate of energy input was required
Answer:
A. 1.0x10^6 J
B. 53 W
C. 7.1x10^-2
D. 330 W
Explanation:
A) work done = mgh
so 71*9.8*1500=1.0x10^6 J
B) power = Work done/time
So P=1.0x10^6/19800 sec
P= 53 W
C) 1 HP =735 W
503 W= 7.1x10^-2 HP
D) efficiency =(output/ input) *100
so 16= (53/input) *100
input= 7.1x10^-2

A curling stone has a mass of 19.1 kg and a velocity of 3.0 m/s. What is the momentum of the curling stone?
Considering the definition of momentum, the momentum of the curling stone is 57.3 [tex]\frac{kgxm}{s}[/tex].
Definition of linear momentumThe linear momentum or quantity of movement is the magnitude that allows us to measure the capacity of a body in motion to exert a force on another that is in its path.
The linear momentum of a particle of mass m or body m moving with a speed v is defined as the product of the mass times the speed:
P = m×v
Where, as previously stated:
P is the moment.m is the mass of the body.v is the speed.The standard units for moment are [tex]\frac{kgxm}{s}[/tex], and moment is always a vector quantity. Its direction and direction coincide with those of the velocity vector.
Momentum of the curling stone
In this case, you know:
P= ?m= 19.1 kgv= 3 [tex]\frac{m}{s}[/tex]Replacing in the definition of momentum:
P = 19.1 kg ×3 [tex]\frac{m}{s}[/tex]
Solving:
P=57.3 [tex]\frac{kgxm}{s}[/tex]
Finally, the momentum of the curling stone is 57.3 [tex]\frac{kgxm}{s}[/tex].

When a light wave enters a medium of greater optical density, select two of the characteristics that will decrease in the wave,
A speed
B
frequency
С
wavelength
D
period
E
amplitude
F
height
Answer:
The speed (A) will decrease
V = F λ (the frequency F remains the same to maintain continuity across the interface)
Therefore (C) the wavelength must decrease
Note: n = speed of light in air / speed of light in medium
When a light wave enters a medium of greater optical density the two characteristics that are: (A) Speed, and (C) Wavelength will decrease in the wave.
It is given that a light wave enters a medium of greater optical density.
It is required to find the characteristics that will decrease.
What is light?It is defined as the type of waves such as sound waves or ocean waves but waves carry energy. Light does not need any medium to travel.
We know that:
[tex]\lambda =\frac{v}{f}[/tex]
Where Lamda (λ) = Wavelength
([tex]v[/tex]) = Speed of wave
[tex](f)[/tex] = Frequency of the wave.
The frequency remains the same to maintain continuity across the interface.

How is the answer d??
Answer:
To keep from falling at the top;
M V^2 / R = M g
This can be rewritten
1/2 M V^2 = M g R /2
2 M g R = 1/2 M V^2 difference in KE between top and bottom
2 M g R + M g R / 2 = 5/2 M g R
Adding the minimum KE at the top to the KE gained when the potential energy of 2 M g R is converted to KE
