We know
work=force*distance=6500*50=?
plz tell me the result !
and feel free to ask if u hv any more confusion

Explain why pressure is not proportional to volume if the temperature changes?

Katen [24]

When temperature increases the particles of the substance move further away from each other and the substance expands, leading to an increase in volume. Since the particles are further away from each other pressure is reduced and that's why pressure is not proportional to volume when temperature changes.

Answer:

a

$a_{max} = 0.00246 \ m/s^2$

b

$k =722.2 \ N/m$

Explanation:

From the question we are told that

The amplitude is $A = 1.8 \ cm = 0.018 \ m$

The period is $T = 17 \ s$

The test weight is $W = 13 \ N$

Generally the radial acceleration is mathematically represented as

$a = w^2 r$

at maximum angular acceleration

$r = A$

So

$a_{max} = w^2 A$

Now $w$ is the angular velocity which is mathematically represented as

$w = \frac{2 * \pi }{T}$

Therefore

$a_{max} = [\frac{2 * \pi}{T} ]^2 * A$

substituting values

$a_{max} = [\frac{2 * 3.142}{17} ]^2 * 0.018$

$a_{max} = 0.00246 \ m/s^2$

Generally this test weight is mathematically represented as

$W = k * A$

Where k is the spring constant

Therefore

$k = \frac{W}{A}$

substituting values

$k = \frac{13}{0.018}$

$k =722.2 \ N/m$

Sea breezes that occur near the shore are attributed to a difference between land and water with respect to what property?

ddd [48]

Answer:

a. mass density

Explanation:

<em>Land and sea breeze that occur near the shore are due to the variation of mass density of air with change in temperature.</em>

When the air gets heated it becomes rarer in density and thus rises up in the atmosphere and its space is occupied by a cooler and denser air that flows to the place.

<em>During the day the land is warmer than the sea so the sea breeze blows and during the night the water bodies are warmer than the land so the land breeze blows.</em>
