You have two beakers of different types of oil, which have different specific heat capacities. You put each beaker in a water ba

th at 50 °C. The water is heated and stays at 50 °C. Which statement is true?
A: If you put the same amount of oil in each beaker, the temperature of the oil in each beaker will be the same at all times.

B:If the mass of oil in the two beakers is the same, the oil with the lower specific heat capacity will heat up more slowly.

C:If the mass of oil in the two beakers is the same, the oil with the lower specific heat capacity will heat up more quickly.

D:The oil with the higher specific heat capacity will heat up more quickly regardless of the mass of oil.

1. Earth releases about 44-46 Tw of heat, in fact heat can be converted into
Aleksandr [31]

Answer:

  even if it all could be used, it wouldn't be enough

Explanation:

The land area of the US is about 5.45% of the world's area, so the amount of released heat over the area of the US is on the order of 2.4 Tw. Current technology for converting geothermal energy to electricity is about 12% efficient, so the available energy might amount to 0.29 Tw if it could all be captured.

Energy consumption in the US in 2019 was on the order of 0.46 Tw. This suggests that even if <em>all</em> of the thermal energy radiated by the Earth from the US could be turned to useful forms of energy, it would meet only about 60% of the US need for energy.

An object of 4 kg has a speed of 6 m/s and moves a distance of 8 m. What is its kinetic energy in joules.
11Alexandr11 [23.1K]

Answer:

The answer to your question is Ke = 72 J

Explanation:

Kinetic energy depends on the speed of and object and its mass.

Data

mass = m = 4 kg

speed = v = 6 m/s

distance = d =  8 m

Kinetic energy = ke = ?

Formula

Ke = (1/2) mv²

Substitution

Ke = (1/2) (4)(6)²

Simplification

Ke = (1/2)(4)(36)

Ke = (1/2)(144)

Ke = 72 Joules

Result

Ke = 72 J
