A 1200 w microwave oven transforms 1.8x10(to the power of 5) J of energy while reheating some food. Calculate how long the food was in the microwave, in mins!? (Please show steps, thanks)

Answers

Answer 1
Answer:
1200 watts = 1200 joules per second

(1.8 x 10⁵ joules) / (1,200 joules/sec) = 150 sec = 2.5 minutes

The city police are in pursuit of Robin Banks after his recent holdup at the savings and loan. The high-speed police chase ends at an intersection as a 2080-kg Ford Explorer (driven by Robin) traveling north at 22.6 m/s collides with a 18400-kg garbage truck moving east at 10.4 m/s. The Explorer and the garbage truck entangle together in the middle of the intersection and move as a single object. Determine the post-collision speed and direction of the two entangled vehicles.

Why is it important for scientists to measure how much precipitation is falling across the world?

Answers

scientists is the answer

Final answer:

Measuring precipitation is essential for predicting weather and climate trends, understanding impacts of climate change, and monitoring ecosystem health as it affects numerous species' habitats and the global water cycle.

Explanation:

Measuring the amount of precipitation falling worldwide is crucial for scientists for several reasons. Firstly, precipitation patterns heavily influence climate and weather patterns globally. Monitoring these patterns helps in predicting weather and climate trends accurately, which is essential for agricultural and water resource planning. Secondly, significant changes in precipitation patterns can indicate climate change. These changes have potential impacts on sea level, global temperature, and biodiversity. Therefore, understanding them plays an important role in developing strategies for mitigation and adaptation. Lastly, quantifying precipitation is also vital for monitoring the health of ecosystems, as it affects the habitats of numerous species and influences the global water cycle.
