A bathysphere used for deep-sea exploration has a radius of 1.50 m and a mass of 1.19 104 kg. In order to dive, this submarine t

Hitman42 [59]

Answer:

m = 2,776.95 kg

Explanation:

given,

radius = 1.5 m

mass = 1.19 x 10⁴ Kg

constant speed, v = 1.4 m/s

Resistive force = 1105 N

density of sea water = 1.03 x 10³ kg/m³

Volume of vessel,

$v=\dfrac{4}{3}\pi r^3$

$v=\dfrac{4}{3}\pi\times 1.5^3$

v = 14.14 m³

Upthrust,

U = ρ g V

U = 1030 x 9.8 x 14.14

U = 142729.16 N

Since the vessel is moving at a constant speed, the resultant force on it should equal zero.

downward acting forces = upward acting forces

Mg = U + resistive force

M x 9.8 = (142729.16+1105)

M=14676.95 Kg

Mass of water,

m = M - mass of vessel

m = 14676.95 Kg- 11,900 kg

m = 2,776.95 kg

Olin [163]

Answer:

The student needs to group variables into dimensionless quantities.

Explanation:

Large experiments take a lot of time to perform because the significant variables need to be separated from the non-significant variables. However, for large quantities of variables, it is necessary to focus on the key variables.

One technique to do that is to use the Buckingham Pi Theorem. The theorem states that the physical variables can be expressed in terms or independent fundamental physical quantities. In other words:

P = n- k

n = total number of quantities

k = independent physical quantities.

A place to start with will be to find dimensionless quantities involving the mass, length, time, and at times temperature. These units are given as M, L, T, and Θ

The grouping helps because it eliminates unwanted and unnecessary experiments.

Unpolarized light is passed through three successive Polaroid filters, each with its transmission axis at 45.0° to the preceding

allsm [11]

Answer:

The percentage is $k = 12.5 \%$

Explanation:

From the question we are told that

The axis is is at $\theta = 45 ^o$

Generally the of intensity light emerging from the first polarizer is mathematically represented as

$I_{1} = \frac{I_o}{ 2}$

Where $I_o$ is the intensity of unpolarized light

Now the light emerging from the second polarizer is mathematically represented as

$I_2 = I_ 1 * cos ^2(\theta )$

$I_2 = \frac{I_o}{2} * cos ^2(45 )$

$I_2 = \frac{I_o}{2} * \frac{1}{2} = \frac{I_o}{4}$

Now the light emerging from the third polarizer is mathematically represented as

$I_3 = I_ 2 * cos ^2(\theta )$

$I_3 = \frac{I_o}{4} * cos ^2(45 )$

$I_3 = \frac{I_o}{8}$

Now the percentage of the intensity of light that emerged with respect to the intensity of the unpolarized light is

$k = \frac{\frac{I_o}{8} }{I_o } * 100$

$k = 12.5 \%$

Can someone help with number 4 please

kondaur [170]

The way I look at these things is like this:

-- The runner covered 12 meters in 4 seconds.
Average speed = 3 meters per second.

-- Speed at the beginning = zero.
In order to make the average 3, Speed at the end = 6 meters per second.

-- Speed increased from zero to 6 meters per second in 4 seconds.
It must have increased 1.5 meters per second each second.

That's choice-#2.
