Which statement BEST explains why the specific heat of water is higher than the specific heat of most other substances?

solniwko [45]

Due to its polarity and hydrogen bonding water can absorb heat without a significant temperature change.. The high specific heat of water helps regulate the rate at which air changes temperature, which is why the temperature change between seasons is gradual instead of sudden, especially near the oceans.

To move a refrigerator of mass 170 kg into a house, a mover puts it on a dolly and covers the steps leading into the house with

Arte-miy333 [17]

Explanation:

The given data is as follows.

mass (m) = 170 kg, Distance (s) = 9.6 m

Height (h) = 3.3 m, Force (F) = 1400 N

First, we will calculate the work performed by her as follows.

W = Fs

= $1400 N \times 9.6 m$

= 13440 J

Hence, minimal work necessary to lift the refrigerator is as follows.

U = mgh

= $170 kg \times 9.8 \times 3.3 m$

= 5497.8 J

Therefore, we can conclude that he performed 5497.8 J of work.

How fast must a bug swim to keep up with the waves it produces? How fast must it move to produce a bow wave?

Elden [556K]

Answer:

A bug must swim as fast as the wave speed to keep up with the waves it produces. Moreso, a boat must be moving faster than the waves it creates to produce a bow wave.

babymother [125]

Wood isn't as tough as rock. Wood also breaks down in weather and cracks under pressure. Plus rocks were more accessible.
