The position of a particle moving along the x axis may be determined from the expression x(t) = btu + ctv, where x will be in meters when t is in seconds. What will be the dimensions of b and c in this case if u = 8 and v = 7?

Answers

Answer 1

Answer:

The dimension of b and c is $b = M^0L^1T^{-8$ and $c = M^0L^1T^{-7$

Calculation of dimension:

Since the x axis may be determined from the expression that shown below.

$x = bt^u + ct^v$

Here, x will be in meters when t is in seconds

Now

Here the dimension of the right side should be equivalent to the left side.

According to the left side the dimension should be same like length or meter so same goes for the right side

So,

$bt^u = M^0L^1T^0\n\nb* T^8 = M^0L^1T^0\n\nb = M^0L^1T^(-8)$

Now for another one it is

$ct^v = M^0L^1T^0\n\nc* T^7 = M^0L^1T^0\n\nc = M^0L^1T^{-7$

Answer 2

Answer:

As per given equation we have

$x = bt^u + ct^v$

now as per the dimensional analysis we can say that dimension of right side of equation must be equal to left side of the equation

now as per left side of equation its dimension is same as length or meter

now we can say it should be meter on right side also

$bt^u = M^0L^1T^0$

$b*T^8 = M^0L^1T^0$

$b = M^0L^1T^(-8)$

similarly for other term we have

$ct^v = M^0L^1T^0$

$c*T^7 = M^0L^1T^0$

$c = M^0L^1T^(-7)$

so above are the dimensions of b and c

When taking a shower are girls suppose to wipe front to back ?

Answer:

Explanation:

I don't think it matters while taking a shower, however, while using the restroom, it is especially encourgaed to wipe front to back. The reasoning behind this is to prevent UTI's that are transferred by fecal particles and bacteria from the anus into the vagina. Hope this helps:)

I think you should always wipe front to back to prevent any type of bacteria from getting near you know..

Suppose a rocket ship in deep space moves with constant acceleration equal to 9.8 m/s2, which gives the illusion of normal gravity during the flight. (a) If it starts from rest, how long will it take to acquire a speed one-tenth that of light, which travels at 3.0 × 108 m/s? (b) How far will it travel in so doing?

Answers

(a).
It starts from rest, and its speed increases by 9.8 m/s every second.
One tenth the speed of light is (1/10) (3 x 10⁸ m/s) = 3 x 10⁷ m/s .
To reach that speed takes (3 x 10⁷ m/s) / (9.8 m/s²) = 3,061,224 seconds .
That's about 35 days and 10 hours.

(b).
Distance traveled = (average speed) x (time of travel)
Average speed = (1/2) of (1/10 the speed of light) = 1.5 x 10⁷ m/s .
Time of travel is the answer to part (a) above.
Distance traveled = (1.5 x 10⁷ m/s) x (3,061,224 sec) = 4.59 x 10¹³ meters
That's 45.9 billion kilometers.
That's 28.5 billion miles.

Why do ice cubes always float at the top of a glass of water?

Answers

Because water is a very very very very very unusual substance ... It's
the only known substance whose solid form is less dense than its liquid
form near the same temperature.

In other words, water is the only known substance for which a solid lump
of it floats in a liquid glass of it.

If that were not true ... if the behavior of the density of water around its
freezing temperature were the same as the density of all other known
substances ... then life on Earth would be impossible.

Think about that for a while ! Ya gotta admire whoever it was that designed water !

Explanation:

the image of a mountain can be seen on the surface of calm water. what property of light is demonstrated?

Answers

Answer:

It is Reflection of light from water surface

Explanation:

When light coming from the mountains incident on the stationary water surface then major proportion of light gets reflected from the surface of water and this will received by the observer eye.

We also know that when light beam gets reflected into the form of beam then it is known as regular reflection.

Here when water surface is calm then the surface is assumed to be plane and in this case the light gets reflected by the surface of water in same direction and we got a good image in the water.

So this property of image is due to reflection of light.

I say it's the regular reflection
