If the amplitude of a wave increases by a factor of 4, how is the intensity changed?

2 answers:

8 0

The intensity increases 16 times.

The relationship between intensity and amplitude is given below:

 I = constant $A^{2}$

Since, A becomes 4 times, A' = 4A
Thus the intensity becomes, I' = constant × (4A)²

⇒ I' = 16A²

Therefore, the intensity of the wave is increased by 16 times

Design a solution that can monitor and minimize the melting of sea ice caused by human activity

dedylja [7]

Answer:

CO2 emissions from fossil fuel burning should be minimized at all cost. The CO2 are gotten when the carbons from hydrocarbons react with air(oxygen). This gas erodes the ozone layer which makes the melting of ice caps faster due to increased amount of heat radiations on the earth. This is the only best and permanent solution to the reduction of the amount of heat rays on the earth which is a global problem.

Objects which reflects back the sunrays could also be inserted into the sea to prevent the melting of the ice caps.

A 60-watt light bulb has a voltage of 120 bolts applied across it and a current of 0.5 amperes flows through the bulb. What is t

Andre45 [30]

Answer:

240 ohms

Explanation:

From Ohms law we deduce that V=IR and making R the subject of the formula then R=V/I where R is resistance, I is current and V is coltage across. Substituting 120 V for V and 0.5 A for A then

R=120/0.5=240 Ohms

Alternatively, resistance is equal to voltage squared divided by watts hence $\frac {120^{2}}{60}=240$

Adding salt variable) causes the boiling temperature of the water variable) to increase.

Flauer [41]

When salt is added, it makes it harder for the water molecules to escape from the pot and enter the gas phase, which happens when water boils, Giddings said. This gives salt water a higher boiling point, she said.
