Answer:
Yes
Explanation:
There will be a force because the large metal sphere is polarized when the rod is placed close to it, this happens because the metal sphere has free electrons and they will be attracted by the positively charged rod, the sphere will remain neutral as a whole (the same number of negative and positive charge), but a portion of the sphere will become more positive and the other more negative, creating this force.
The telescope has the ability to enlarge an image and depends on the combination of lenses used.
Explanation:
Eyepiece performs magnification. The size of primary lens or primary mirror determines the Light gathering power. The main functions of telescope are light gathering, resolution and magnification.
The light gathering power has the ability of a telescope to collect more light than human eye. The purpose of telescope is to focus photons.
Neglecting losses in a transformer, it's input and output <em>power </em>are equal.<em> (C)</em>
The body systems that help cells get the energy they need are the digestive system and circulatory system. The first system is the digestive system because when you eat food, your body breaks it down using the stomach and other different parts of the digestive system. The next one is the circulatory system because your blood carries the nutrients you acquired from food you digested to the cells throughout your body.
The efficiency<span> of a heat engine can be calculated as the ratio of the work obtained to the heat energy put in at the high temperature,
efficiency = Work_max/T</span>high<span>.
or
efficiency=TH-TL/TH,
where TH is the high temperature and TL is the low temperature.</span><span>
In our case the heat engine operates between 600K and 800K. SO, TH=800K and TL=600K.
The efficiency is: e=800-600/800=200/800=0,25</span>
