Answer:
The oscillations are perpendicular to the direction of travel.
Step-by-step explanation:
An electromagnetic wave has oscillating <em>electric</em> and <em>magnetic</em> fields.
They oscillate at right angles to each other and perpendicular to the direction of travel of the wave.
Answer:
Explanation:
according to the balance chemical equation
2 moles of c6h14 give us 14 moles of H2O
now mass(in gram) of 2 moles of C6H14 is
moles=mass/molar mass
mass=molar mass*moles
molar mass of C6H14 is 86 therefore
mass=86*2=172
now mass of 14 moles of water is
mass=molar mass*moles
molar mass of water is 18
mass=18*14=252
from the above calculations we conclude that
172 grams of C6H14 produce 252 grams of water
so 1.28 grams of C6H14 produce =252*1.28/172=1.87 grams of water
result is that 1.28 grams of C6H14 produced 1.87 grams of water

Answer:
In 1897, the British physicist J. J. Thomson (1856–1940) proved that atoms were not the most basic form of matter. He demonstrated that cathode rays could be deflected, or bent, by magnetic or electric fields, which indicated that cathode rays consist of charged particles (Figure 2.2.2 ). More important, by measuring the extent of the deflection of the cathode rays in magnetic or electric fields of various strengths, Thomson was able to calculate the mass-to-charge ratio of the particles. These particles were emitted by the negatively charged cathode and repelled by the negative terminal of an electric field. Because like charges repel each other and opposite charges attract, Thomson concluded that the particles had a net negative charge; these particles are now called electrons. Most relevant to the field of chemistry, Thomson found that the mass-to-charge ratio of cathode rays is independent of the nature of the metal electrodes or the gas, which suggested that electrons were fundamental components of all atoms.
