Answer: work of 17.52 J is done
Explanation:
Given that;
Force F = 12 N
distance d = 1.46 m
work W = ?
we know that work done is force F multiple by distance d
so Work W = force F × distance d
we substitute our values
Work done W = 12 × 1.46
W = 17.52 J
Therefore a work of 17.52 J is done

The answer is <u>(E.) Both 1 & 2.</u>
Urban heat islands (UHI) affect local air current and weather conditions including:
1) increased number of thunderstorms over cities in summer months
2) lingering dust domes over cities
Explanation:
As urban areas develop, their landscape and environment experience changes, especially in the advent of industrialization. Urban heat islands (UHI) is the phenomenon that occurs when these areas become significantly warmer than their surrounding due to these human activities.
Some of the effects of UHI is that it <em>compromises air quality </em>by increasing the production of pollutants such as ozone, and it decreases the water quality, m<em>aking warmer waters</em> flow into surrounding streams, causing imbalance in the ecosystem.

Answer:
Assume that the ball undergoes motion along a straight line. ... F = m A Force = (mass) x (acceleration) The question tells you the mass and the acceleration. All YOU have to do is take the numbers and pluggum into Newton's 2nd law. F = m A = (0.75 kg) (25 m/s²) = (0.75 x 25) kg-m/s² = 18.75 Newtons .
