Answer:
The answer to your question is Energy = 36.036 J
Explanation:
Data
mass of Copper = 39 g
ΔT = 24°C
C = 0.0385 J/g°C
Q = ?
To calculate the energy absorbed just substitute the values given in the specific heat formula.
Q = mCΔT
Substitution
Q = (39)(0.0385)(24)
Simplification
Q = 36.036 J
The magnetic forces exerted by the magnet can act at a distance on other magnets or on objects containing certain metals. The magnetic fields showcase the presence of magnetic forces. The magnetic forces arise due to attraction and repulsion of the poles inside the material. Opposite poles attract each other while similar poles repel each other.
Answer: The are waves that consist of vibrating electric and magnetic fields. They transmit energy through matter or across space. Some electromagnetic waves are generally harmless. Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency.
Explanation:
Answer:
5 pounds 2 ounces.
Explanation:
1 pound = 16 ounces
So just add the 2 ounces to the pounds.
The balanced equation that describes the reaction between hydrogen and oxygen to produce water is 2 H2+O2= 2H2O. Hence to produce 2 moles of water 2 moles of hydrogen is equivalently needed. For the given, 0.253 moles water thus needs 0.253 moles of hydrogen, too.
