Which sentence provides evidence that heat travels from Earth’s mantle up to its crust?
olasank [31]

B. Earth’s outer surface is cooler than its interior layers.

Explanation:

  • The option given above is showing us that the temperature in the interior of the earth is higher than the temperature in the outer layer.
  • There is travel of heat from the inner core of the earth to the earth's crust. Due to the loss of heat when it reaches the outer layer, there arises a temperature difference.
  • The heat loss is due to the absorption of heat during its transfer. Hence, option B is the answer.

A glass falls from a table top and smashes on the floor 0.6 seconds later. How high is the table?
soldi70 [24.7K]

Answer:

1.8 m

Explanation:

Given: Glass falls from a table, smashes 0.6 seconds later

To find: How high a table is

Formula: Vv=gt, dv=1/2gt^2, t=2d/g

Solution: A table's <em>height</em> is measured from the top of the edge down to the floor. The tables are shown both have a height of 30 inches, which is common for many tables.

<u>Data</u>

  • t = 0.6s
  • g = 9.81 m/s²
  • d = ?

<u>Equation</u>

  • d = \frac{1}{2}gt²

<u>Math & Units</u>

  • d = 4.905 (0.6²)
  • d = 442.676

Hence the table is 1.8 m high

Which explains why more energy is released in nuclear reactions than in chemical reactions? Chemical reactions are always endoth
Natali [406]
More energy is released in nuclear reactions than in chemical reactions; this is because in nuclear reactions, mass is converted to energy. Nuclear energy released in nuclear fission and fusion is several 100 million times as large as an ordinary chemical reaction like the combustion process. The reason why nuclear energy release so much energy is because tremendous amounts of energy is released at one time. The nuclei in a nuclear reaction undergo a chain reaction, causing the neutrons to move extremely fast and release high amounts of energy.
