The student quickly discovers that placing the marshmallow over the flame is more effective than heating the marshmallow on the
ANEK [815]

Answer:

The answer is convection.

Explanation:

There are three types of heat transfer: conduction, convection and radiation.

  • Conduction occurs when two objects touch each other and transfer heat.
  • Convection occurs when an object heats its surrounding fluid (like air, or water) and, since the hot fluids are less dense than the cold ones, they go up. So convection is a type of heat transfer that usually goes from down to up.
  • Radiation occurs when objects emanate heat in the form of electromagnetic waves that propagates in all directions.

So in this case, when the marshmallow is above the fire, it is exposed to convection, which does not occur when it is on the side of the fire.

A space probe is directly between two moons of a planet. If it is twice as far from moon A as it is from moon B, but the net for
Dennis_Churaev [7]

Answer:

c. Moon A is four times as massive as moon B

Explanation:

Let's assume the:

  • mass of the object = m\,kilogram
  • mass of the moon A = M_A\,kilogram
  • mass of the moon B = M_B\,kilogram
  • distance between the center of masses of the object and moon B = r\,meters

According to the given condition the object is twice as far from moon A as it is from moon B

  • ∴distance between the center of masses of the object and moon B = 2r\,meters

<u>As we know, gravitational force of attraction is given by:</u>

F=G\frac{m_1.m_2}{r^2}

<em>According to the condition</em>

Force on m due toM_B=Force on m due toM_A

G\frac{m.M_A}{(2r)^2} =G\frac{m.M_B}{(r)^2}

\frac{M_A}{4r^2} =\frac{M_B}{r^2}

M_A=4M_B

A race car travels 99 m/s around a circular track of radius 52 m. What is the magnitude of the resultant force on the 1900 kg dr
Dmitriy789 [7]

Answer:

Force = 358.11 kN

Explanation:

Resultant force = Centripetal force.

\texttt{Centripetal force, F = }\frac{mv^2}{r}

Mass, m = 1900 kg

Velocity, v = 99 m/s

Radius, r = 52 m

Substituting

            \texttt{Centripetal force, F = }\frac{mv^2}{r}\\\\F=\frac{1900\times 99^2}{52}\\\\F=358113.46N\\\\F=358.11kN

Force = 358.11 kN
