Power is the rate that work is done or work per unit time.
So doing more work per unit time creates more power.
Power = Work / time
Answer:
0.25p.a
Explanation:
force=15N area=60m²
so pressure =force/area =15N/60m²=0.25p.a
Answer:
Current that flows through any one of the resistors has a value of 12 amperes.
Explanation:
When a group of resistors are connected in series, the same current flows through each resistor. According to the Ohm's Law, the circuit can be represented as follows:
Where:
- Voltage of the battery, measured in volts.
, , - Electric resistance of the first, second and third resistors, measured in ohms.
- Current, measured in amperes.
If , then:
Current that flows through any one of the resistors has a value of 12 amperes.
States that the total energy of an isolated system remains constant; it is said to be conserved over time
So the answer is “cannot be created of destroyed”
Answer:
Global warming pollution
When we burn oil, coal, and gas, we don't just meet our energy needs—we drive the current global warming crisis as well. Fossil fuels produce large quantities of carbon dioxide when burned. Carbon emissions trap heat in the atmosphere and lead to climate change
