6.3^2 + 12^2 = thirteen.6^2. Left hand area balances suitable hand area! The triangle with factors 6.3 cm, 12 cm and thirteen.6 cm is nice-angled. Makes issues easier. Draw a triangle XYZ with XY = 6.3 cm, YZ = 12 cm and XZ = thirteen.6 cm (the hypotenuse) --- on a sheet of paper. be conscious that XY and YZ has a suitable perspective between them. Circle X and Y. that's the place there are 2 currents of length 15.0 A coming into the web site frequently. The magnetic field located at factor located at a distance R far flung from an prolonged straight away cutting-edge I is given by way of B = (mu-nought)*(I) / (2*pi*R) “mu-nought” is (4*pi*10^-7), so B = (2I)/R the two currents make magnetic fields B1 and B2 at Z, so as that they are at suitable angles with XZ and YZ respectively. the attitude between B1 and B2 is theta, the place theta is likewise the attitude at Z in triangle XYZ. Theta is rather discovered through fact all 3 factors of XYZ are prevalent, making use of easy sin, tan or cos. Draw a parallelogram with 2 arrows for factors, of length B1 and B2, with the attitude theta between them. locate the diagonal of the parallelogram between B1 and B2, and the attitude it makes with B1. for this reason you be responsive to that's the dimensions and path of the ensuing field. ok, right this is the place physics ends, something is arithmetic. It’s as much as you presently to the two draw to scale or calculate.
Answer:
3.6512 rad/s
37.97248 m/s
6.7808 m/s²
138.645118976 m/s²
Explanation:
r = Radius of centrifuge = 10.4 m
Differentiating with respect to time
At t = 5.6 s

The tangential acceleration is 6.7808 m/s²
Radial acceleration is given by
The radial acceleration is 138.645118976 m/s²
Answer:
Image result for State the general purpose of an experiment, using the terms dependent and independent variable
You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable

Use the conservation of angular momentum; angular momentum at the beginning = angular momentum at the end
Conservation of angular momentum:
I1 w1 = I2 w2
Where I is the moment of inertia. For a sphere, I=2/5 m R^2. Substituting into the equation above we get
w2 = I1 w1 / I2 = w1 m1 R1^2 / (m2 R2^2)
w2 = w1 4 * (R1/R2)^2
= 4*(1)*(7E5/7.5)^2
= 3.48E10 revs/(17days)
= 2.04705882 x 10^9 revs/sec
