Gain in decibels is given by;
Gain db = 10*log (Po/Pi), where Po = Power output, Pin = Power input
Substituting;
Gain in db = 10 * log (50/5) = 10 db
Variables shift both the long-run and short-run aggregate-supply curves are productivity, labor Wage Costs and taxes and other costs.
<h3>What is aggregate-supply?</h3>
The entire quantity of goods and services that enterprises in a national economy intend to sell during a certain time period is known as aggregate supply
Variables shift both the long-run and short-run aggregate-supply curves are ;
1. Productivity
2. Labor Wage Costs.
3. Taxes and other costs -
4. Material Prices.
5. Size of labor force.
6. Stock of Capital.
Hence, variables shift both the long-run and short-run aggregate-supply curves are productivity, labor Wage Costs and taxes and other costs.

Answer:
• 36.4 kg of coal.
• 80 pounds of coal.
Explanation:
Using proportionality constant,
Mass of coal = 1,000,000/27,500,000 btus/metric ton
= 0.0364 metric tons of coal
Mass of coal = 1,000,000/25,000,000 btus/ton
= 0.04 tons of coal.
Converting metric tons to kilogram,
1 metric ton = 1000kg,
0.0364 metric ton;
= 36.4 kg of coal.
Converting tons to pounds,
1 ton = 2000 pounds,
0.04 metric ton;
= 80 pounds of coal.
Answer:
Workdone = 8400 Nm
Explanation:
Given the following data;
Force = 2100 N
Distance = 4 meters
To find the work done;
Workdone = force * distance
Workdone = 2100 * 4
Workdone = 8400 Nm
Therefore, the amount of work done on the car is 8400 Newton meters.
1. The vibration is perpendicular to the direction of travel of transverse waves.
2. The vibration is parallel to the direction of travel of longitudinal waves.
3. Compression waves contain compressions and rarefactions.
They are longitudinal waves.
4. You produce a transverse wave when you move one end of a
horizontal spring up and down.
5. All waves have wavelengths.
