Answer:C.The tube should be held vertically, perpendicular to the ground.
Explanation: Power lines are mainly overhead power installation that transfer electric energy from one place to another. Electric power lines contains both Magnetic field and Electric field.
Potential difference is the change in the amount of energy carried by an electric circuit from one point to another. TO MAXIMIZE THE POTENTIAL DIFFERENCE BETWEEN ONE END OF THE TUBE AND ANOTHER? THE TUBE SHOULD BE HELD VERTICALLY,PERPENDICULAR TO THE GROUND.
Back then, Robert Hooke found cells from a cork and named it cells. Later on, Matthias Schleiden found cells from plant parts and concluded that all plants are made of cells. Theodor Schwann, after observing many different animal cells, concluded that all animal have cells. Several years later, Rudolf Virchow hypothesized that cells divide to form new cells. Virchow proposed that every living organism has cells. His observations and conclusions and those of others are summarized in the cell theory
Answer:
hurricanes last longer that tornadoes
The volcanoes and earthquakes that are along the ring of fire are caused by the amount of movement of tectonic plates in the area. Plates overlap at convergent boundaries called subduction zones. As rock is subducted, it melts and becomes magma.
Hope this helps! :)
Answer:
The ratio between W2 and W1 is
p=1.5
Explanation:
The W2/W1 ratio equals the efficiency ratio, since the heat input is constant.
Initially, the Carnot efficiency is
1 - (Tc/Th)
1 - 400/800 = 0.50
After lowering Tc, the efficiency becomes
1 - (Tc/Th)
1 - 200/800 = 0.75
So to determine the ratio between W2 and W1
W2/W1 = 0.75/0.50 = 1.5
