Transformer. Its an electrical device that uses electromagnetic induction to pass an alternating current (AC) signal from one electric circuit to another, often changing the voltage and electrical current
Answer:
184 Km
Explanation:
given,
speed of S wave = 4.50 Km/s
speed of P wave = 7.80 Km/s
reading time difference = 17.3 s
we know,
distance = speed x time
time taken by s-wave
time taken by the P-wave
now,
t₁ - t₂ = 17.3 s
3.3 x = 607.23
x = 184 Km
distance of the focus from the station is 184 Km.
Answer:
A sedimentary rock is off of a boulder.
Explanation:
87.69 grams of calcium metal is required to react with 7.75 g water to produce calcium hydroxide and hydrogen gas.
Ca (OH)2+2H2 = CaH2 + 2H2O
Convert grams of hydrogen to moles of hydrogen.
H2 has a molar mass of 2.016 g/mol.
1 mol H2 x 8.400g H2
2.016g H2 equals 4.1667 mol H2
Calculate the moles of CaH2 using the molar ratio.
The molar ratio is 1 mol CaH2: 2 mol H2, according to the equation that is balanced.
2.0833 mol CaH2 = 4.1667 mol H2 1 mol CaH2 2 mol H2
grams of CaH2 to CaH2
CaH2 has a molar mass of 42.09 g/mol.
1.mol CaH2=87.69 g CaH2 2.0833mol CaH2=42.09 g CaH2
87.69 g CaH2 are required for the reaction.
