- Two towns are 145 km apart. A bus leaves one of the towns . . . - Socratic
The car would travel 90 km in 1 hour, so it will travel 45 km in half an hour (30 min) The bus will travel 30 km They have traveled a total of 75 km of the 145 km between the towns, so there is 145-75=70 km between them
- The sum of the first nth term of a geometric series is 145 . . . - Socratic
The sum of the first nth term of a geometric series is 145 and the sum of the reciprocal is 145 33 The first term is 1 What is n and the common ratio? Precalculus
- Question #5b826 - Socratic
What we're really doing here is that we're given an initial state with # ["BrCl"]_i = "0 050 M"#, and we're given #K_ (eq)#, which is defined for a final state we define as equilibrium, when the rate of the forward reaction is equal to that of the reverse reaction
- Question #a6cce - Socratic
The wavelength is lambda=1 03xx10^(-7) m Detailed solution below There is a variety of ways to calculate this, but I will use the method that I think best suits a chemistry approach to the question The energy of each stationary state of hydrogen is given by E_n=-1311 n^2 where I use a value for the numerator that has units of kJ per mole (This is the equivalent of 13 6 eV if you are
- Solve # { (sqrtx (1-4x-y)=2), (sqrty (1+4x+y)=6):}# - Socratic
No real solutions Calling alpha = 4x+y we have { (sqrtx (1-alpha)=2), (sqrty (1+alpha)=6):} then 2 alpha = (1+alpha)^2- (1-alpha)^2=36 y-4 x or 4x+y = 9 y-1 x we
- A triangle has sides A, B, and C. The angle between sides A . . . - Socratic
The length of side A is 10 145 (3dp) The angle between sides A and B is _c= pi 8=180 8=22 5^0 The angle between sides B and C is _a= pi 12=180 12=15^0 Given C=15; A=?
- If the measures of a triangle are 90°, 55°, and 3x - Socratic
=> x = 10 The measures (angles) of a triangle sum to 180^o =>90 + 55 + (3x+5) = 180 =>145 + (3x+5)=180 =>3x + 5 = 35 =>3x = 30 => x = 10
- Question #e7625 - Socratic
Light can travel like a wave or like a particle (photons) Louis de Broglie (1892-1987) related both light movements The formula relates the wavelength to the momentum of a wave particle #λ = h p#
