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:
Mass of water = 41.8 g
Explanation:
Given data:
Mass of water = ?
Change in temperature = 3.0 °C
Specific heat capacity = 4.184 j/g.°C
Heat absorbed = 525 j
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 3.0°C
Now we will put the values in formula.
525 J = m × 4.184 j/g.°C × 3.0°C
525 J = m × 12.552 j/g
m = 525 J/ 12.552 j/g
m = 41.8 g
Answer:
Ka = Kw / Kb
Explanation:
Hello,
By means of all dissociations, considering the relationship between Ka (acid dissociation constant), Kb (basic dissociation constant) and Kw (water's dissociation constant) a feasible way to obtain Ka in terms of Kb is:
Whereas Kw is always equal to 1x10⁻¹⁴, the answer is: Ka = Kw / Kb.
