Answer:
12 A
Explanation:
Given,
Power of electric kettle=2.2 kW=2200W (since 1kW=1000W)
Voltage=180V
Current=?
Power = Voltage*Current
Current = Power ÷ Voltage
=2200W ÷ 180V
=12.22 Ampere
=12 A

Pressure is inversely proportional to area, the little the area, the more the pressure.the bigger the area,the lesser the pressure
Answer:
12.267 seconds approximately.
Explanation:
The units can be simplified into m/s, in which case you would have 61000/3600. Simplify that to 16 and 17/18. This is your meters per second, so multiply that by .724 to get the answer.
Answer:
4987N
Explanation:
Step 1:
Data obtained from the question include:
Mass (m) = 0.140 kg
Initial velocity (U) = 28.9 m/s
Time (t) = 1.85 ms = 1.85x10^-3s
Final velocity (V) = 37.0 m/s
Force (F) =?
Step 2:
Determination of the magnitude of the horizontal force applied. This can be obtained by applying the formula:
F = m(V + U) /t
F = 0.140(37+ 28.9) /1.85x10^-3
F = 9.226/1.85x10^-3
F = 4987N
Therefore, the magnitude of the horizontal force applied is 4987N
Answer:
Smoky Mountains specific spots--such as a factory's smokestacks--where large quantities of pollution are discharged
Explanation:
Point source pollution is characterized by the following components:
- It is a single source
- The source is identifiable
- The source is known to release pollutants into the environment
From the options, <em>Smoky Mountains specific spots--such as a factory's smokestacks--where large quantities of pollution are discharged </em>ticked all the necessary box for a point source pollution.
