Let us assume a man travelled from a point A to a point B over a distance 'd'. After a while he travels the same distance back to point A.

Therefore, since his initial and final positions are the same, displacement is equal to zero, and the distance travelled is (d + d) = 2d, which is not zero.

What is indirect sunlight? how does the tilt of the earth affect which type of sunlight the earth receives?

suter [353]

Indirect sunlight is sunlight that doesn't shine onto a plant at full strength and is weakened by something coming between it and the plant. the tilt of the earth on it's axis allows more direct sunlight on certain parts of the earth at particular times

Can anyone plz answer this?

Scrat [10]

Answer:

I would say C

Explanation:

A is a steep or about 45° angle while B appears to be a straight down angle of 0°. So if you take that into account, if you are subtracting A and B, it would be around in between. It will probably not be backwards because neither is facing to the left except the answer choices so B is wrong (the answer B).

R is even steeper than before, and if you are subtracting, it would probably be C.

A solid cylindrical object has a mass of 2.0 kg, a diameter

omeli [17]

Answer:

I = 0.0025 kg.m²

Explanation:

Given that

m= 2 kg

Diameter ,d= 0.1 m

Radius , $R=\dfrac{d}{2}$

$R=\dfrac{0.1}{2}$

R=0.05 m

The moment of inertia of the cylinder about it's axis same as the disc and it is given as

$I=\dfrac{mR^2}{2}$

Now by putting the all values

$I=\dfrac{2\times 0.05^2}{2}$

I = 0.0025 kg.m²

Therefore we can say that the moment of inertia of the cylinder will be 0.0025 kg.m².

A man walks 400 m in the direction 45° north of east. Represent this vector graphically by

Marrrta [24]

Answer:

Explanation:

Coordinate system is one that describe the location of an object in a given plane. It implies the use of axes (coordinates) and points.

Given that the man in the question walks 400 m due north of east. The cardinal points can be used in this case, with the north and east cardinals as the required axis.

scale = $\frac{length on drawing}{original length}$

= $\frac{10}{400}$

= $\frac{1}{40}$

scale = 1:40

This is a reduced scale which implies that 1 cm on the drawing is equal to 40 m on the original length.

The man's direction is $45^{o}$ north of east.

The graphical drawing of the vector is herewith attached to this answer.
