Wave A has a long fetch. Wave B has a short fetch. Which of the following statements is true? Wave A is more powerful than Waveb. Wave B is more powerful than Wave
a. Both waves are equally powerful.

Answers

Answer

Correct answer is

wave A is more powerful than wave B

Explanation

Fetch of a wave is the length of water over which a wind blow. It is clear that the wave which has longer fetch will have higher energy level. And higher energy level wave will be more powerful that wave which has short fetch. hence wave A which has longer fetch than wave B will be more powerful that wave B.

The following statement that is true is : wave A is more powerful than wave B

Longer Fetch tend to create a higher energy level, which make the wave with longer fetch is stronger than the one with shorter fetch

5,000 joules of thermal energy were applied to 1-kg aluminum bar. What was the temperature increase?

Answers

Answer:

ΔT = 4.9°C

Explanation:

The thermal energy of the bar can be given as follows:

Thermal Energy = mCΔT

where,

m = mass of bar = 1 kg

C = specific heat capacity of aluminum = 1020 J/kg.°C

ΔT = Change in Temperature = ?

Therefore,

5000 J = (1 kg)(1020 J/kg.°C)ΔT

ΔT = (5000 J)/(1020 J/°C)

ΔT = 4.9°C

In which example is government encouraging innovation?Pollution permits are issued by the government.

A government agency constructs a dam.

Patents and copyrights are issued by the government.

Regulations require that cigarette packages advise consumers of health risks.

Answers

The correct answer is PATENTS AND COPYRIGHTS ARE ISSUED BY THE GOVERNMENT.

A government is said to be encouraging innovation if it takes special steps to encourage the citizen to be creative in their endeavors. Innovation is one of the key ingredient that a nation needs to grow and it is the responsibility of the government to promote it. By issuing patents and copyright, a government can encourage the citizen to be original in their works and to produce new things.

A seismogram shows that P waves travela. at the same speed as surface waves.
b. more slowly than S waves.
c. at the same speed as S waves.
d. faster than S waves.

Answers

A seismogram shows that P waves travel faster than S waves. The answer is letter D. This is because P waves can push and pull the sound waves through a liquid or solid medium. The S wave can only move to the solid medium and solids have more compact molecules than the liquid so it travels slow.

Explanation:

Because P waves are the fastest seismic waves, they will ordinarily be the original 1 that your seismograph records. The following set of seismic waves on your seismogram will be the S waves. These are normally higher than the P waves. Often they are the only waves filmed a long distance from medium-sized earthquakes.
