Why does heat flow from a body at higher temperature to body at lower temperature?​
pychu [463]

Because, body at higher temperature has higher average KE of molecules and body at lower temperature has lower average KE of molecules. When two bodies having higher temperature and lower temperature are keep in contact, the body at higher temperature shares their energy to molecules at lower temperature.

A paintball is fired horizontally from a tower 45 m above the ground. If the paintball gun fires at 90 m/s… How long does it tak
ankoles [38]

Answer:

The time taken for the paint ball to hit the ground is t =  2.143 \ s

The distance of the landing point from the tower is d = 192.86 \  m

Explanation:

From the question we are told that

   The height of the tower is h =  45 \ m

    The speed of the paintball in the horizontal direction is  v_x =  90 \  m/s

Generally from kinematic equation we have that

      h =  ut + \frac{1}{2} at^2

Here u is the initial  velocity of the paintball in the vertical direction and the value is 0 m/s , this because the ball was fired horizontally

         a is equivalent to g  = 9.8\ m/s^2

        t is the time taken for the paintball to hit the ground

   So    

       45  =  0* t + \frac{1}{2} 9.8 * t^2

=>    t =  2.143 \ s

Generally the distance of its landing position from the tower is

         d = v  *  t

=>      d = 90 *  2.143

=>    d = 192.86 \  m

Explain how carbon is cycled between the hydrosphere and geosphere. Use specific examples.
joja [24]
Carbon is found in the solid form in geosphere of our earth. Coal and oil are some of the examples of materials containing carbon in the geosphere. when the coal or oil is burnt, carbon dioxide is formed and released in atmosphere. This carbon dioxide is absorbed by the water of the hydrosphere with the help of algae and plankton. The water turns acidic in nature. This way carbon is transferred from geosphere to hydrosphere.

A spring has a force constant k, and an object of mass m is suspended from it. The spring is cut in half and the same object is
kenny6666 [7]

Answer:

f2/f1 = \sqrt{2}

Explanation:

From frequency of oscillation

f = 1/2pi *\sqrt{k/m}

Initially with the suspended string, the above equation is correct for the relation, hence

f1 = 1/2pi *\sqrt{k/m}

where k is force constant and m is the mass

When the spring is cut into half, by physics, the force constant will be doubled as they are inversely proportional

f2 = 1/2pi *\sqrt{2k/m}

Employing f2/ f1, we have

f2/f1 = \sqrt{2}

Which is the union of one man and one woman called?
tensa zangetsu [6.8K]
<h2>Answer: C.Monogamy </h2>

Explanation:

Monogamy is a term that refers to the sentimental and sexual bond that <u>does not allow the multiplicity of spouses. </u>

This means that love relationships are based on exclusivity, on maintaining a unique bond with your partner, refusing to develop the same kind of union or the same actions with other people.
