Answer:

0 J

Explanation:

If it's at the same temperature then it doesn't need more heat. So it'd be 0 J since it's already at 0C.

Which area of Earth is most similar to the sun’s convection zone?
Pavlova-9 [17]
I would say the correct answer is the third option. The area of the Earth that is most similar to the Sun's convection zone would be the mantle. The convection zone of the sun is its outermost layer where heat transfer by convection happens which is similar to the Earth's mantle.

A comet with a mass of 7.85 × 1011 kg is moving with a velocity of 25,000 m/s. calculate its kinetic energy.
Nadusha1986 [10]
The kinetic energy of an object is given by:
K= \frac{1}{2}mv^2
where
K is the kinetic energy
m is the mass of the object
v is its velocity.

The comet in our problem has a mass of m=7.85 \cdot 10^{11} kg and a velocity of v=25000 m/s, so its kinetic energy is:
K= \frac{1}{2}(7.85 \cdot 10^{11} kg)(25000 m/s)^2=2.45 \cdot 10^{20}J

A 1300-kg car moving on a horizontal surface has speed v = 60 km/h when it strikes a horizontal coiled spring and is brought to
slega [8]

The stiffness constant of the spring is 68,290.3 N/m

<h3> Stiffness constant of the spring</h3>

Apply the principle of conservation of energy;

U = K.E

¹/₂kx² = ¹/₂mv²

kx² = mv²

k = mv²/x²

where;

  • m is mass
  • v is speed = 60 km/h = 16.67 m/s
  • x is the distance

k = (1300 x 16.67²)/(2.3²)

k = 68,290.3 N/m

Thus, the stiffness constant of the spring is 68,290.3 N/m.
