A spring scale measures weight because <span>It works by Hooke's Law, which states that the force needed to extend a </span>spring<span> is proportional to the distance that </span>spring<span> is extended from its rest position. Therefore, the </span>scale<span> markings on the </span>spring<span> balance are equally spaced. A </span>spring scale<span> can</span>not measure mass<span>, only </span>weight<span>. hope that helped</span>
Well minerals are in the water we drink every Day, even the food we eat. Minerals are contained in rocks so there for both are important to life
The maximum kinetic energy will be equal to maximum potential energy thus the potential energy will be
mgh = 66*10*5 = 3300 j
Answer:
3amps
Explanation:
voltage v = current I × resistance R
current = voltage÷ resistance = 90÷30= 3amperes
