magnet B has a greater magnetic pull than magnet A
<span>PE @ 0.5m = mgh = 4.41 J
KE @ 0.5m = 0.5mv^2 = 2.91 J
ME @ 0.5m = 4.41 + 2.91 = 7.32 J
7.32 J</span>
Answer:
2.677 J/g°C
Explanation:
Quantity of heat required to raise the temperature of the metal,
Q = mc∆T
where m is the mass of the metal, c is the metal's specific heat capacity, and ∆T is the change in temperature that accompanies the heat transfer process
20.0J = 50.0g × c × 150°C
c = 20.0J/(50.0g × 150°C)
c = 2.677 J/g°C
Answer:
Explanation:
Photosynthesis is an extremely important process for plants, algae, and some bacteria. It helps create their "food", which is glucose. It is turned into energy so the organism can grow, repair damages, and carry out other processes.
The equation for photosynthesis is as follows:
Water, carbon dioxide, and light energy from the sun are converted to glucose and oxygen.
Roots are important for obtaining <u>water</u>. Since they reach into the soil, they can absorb the water. Then, capillary action draws the water up the stem into the xylem and then into the leaves, where photosynthesis occurs.
Answer:
The balance reaction is
2Pb(NO3)2 ----》4NO2+2PbO+O2
hence the value of a,b,c,d are 2,4,2,1 respectively!
