Well that's a not easy task. <span>The specialized forecasters analyze near-real-time ground- and space-based observations to assess the current state of the solar  environment which includes the areas from the Sun to the Earth and points in between. Space weather forecasters also analyze the pattern of solar activity. </span>

A full truckload of garbage has a mass of 26370 pounds . What is this mass in kilograms?
Likurg_2 [28]
  • The mass in kilograms is (11971.98 Kg)

  • Pounds can be  converted to pounds to kilograms by using this conversation (1 pound = 0.454 kilogram)

<em />

  • <em>Let X= mass of the object in kilograms</em>

  • <em>(1 pound = 0.454 kilogram)</em>
  • 26370 pounds = X kilograms

  • <em>If we cross multiply, we have </em>

  • (0.454 kilogram × 26370 pounds) = X kilograms

X = 11971.98 Kg

  • Therefore, mass in kilograms is  (11971.98 Kg)

The reaction
scZoUnD [109]

Answer:

The correct answer is option A.

Explanation:

POCl_3 (g)\rightleftharpoons POCl (g) + Cl_2 (g)

Reducing the partial pressure of chlorine gas means that removal of chlorine gas from the equilibrium will shift the equilibrium in the direction according to Le Chatelier's principle.

On a removal of product from the equilibrium shifts the reaction in the forward reaction for reestablishment.So, when the partial pressure of chlorine is reduced by 50% the equilibrium will shift in forward direction in which POCL_3 will be consumed to form more chlorine gas.

Hence, A is correct .

The specific heats and densities of several materials are given below: Material Specific Heat (cal/g·°C) Density (g/cm3) Brick 0
abruzzese [7]

<u>Answer:</u> The change in temperature is 84.7°C

<u>Explanation:</u>

To calculate the change in temperature, we use the equation:

q=mc\Delta T

where,

q = heat absorbed = 1 kCal = 1000 Cal    (Conversion factor: 1 kCal = 1000 Cal)

m = mass of steel = 100 g

c = specific heat capacity of steel = 0.118 Cal/g.°C

\Delta T = change in temperature = ?

Putting values in above equation, we get:

1000cal=100g\times 0.118cal/g^oC\times \Delta T\\\\\Delta T=\frac{1000cal}{100g\times 0.118cal/g^oC}\\\\\Delta T=84.7^oC

Hence, the change in temperature is 84.7°C
