Answer:
Place A along the x-axis, B along the y-axis, and then C is 30 deg below the negative x-axis.
A = Cx to balance forces on the x-axis
Cx = -25 cos 30 = -21.65 kN
A = Ax = 21.61 kN balances forces in the x-direction
Likewise
Cy = -25 sin 30 = -12.5 kN
B = By = 12.5 kN balances forces in the y-direction
The length of the radii are not important (consider a force table)
Answer:
The ammeter show you that there are 5 amperes of current
Explanation:
Amperes is the unit of current
Answer: its the second (B) option, n1sintheta1=n2aintheta2
theta is the thing that looks like a 0 with the across.
Explanation: I got it right
Answer:
True
Explanation:
The statement is true because According to Schrödinger it's not possible to get the exact position of where an electron is located. However, he showed from an equation that we can at determine the most likely area where an electron will be and he said they are most likely to be in the most dense area of the clouds.
