A postal employee drives a delivery truck over the routeshown in Fig.. Use the method of components to determine themagnitude and direction of her resultant displacement. In a vector-additiondiagram (roughly to scale), show that the resultant displacementfound from your diagram is in qualitative agreement with theresult you obtainedby using the method of components.

I need help on this problem: In the following right triangle, side c = 25 m and angle theta = 53.13. Find each of the following. Express each answer to the correct number of significant figure and use scientific notation if needed.

As shown in the diagram below, a soccer player kicks a ball directly toward the goal along a displacement vector r, which has a length of 9.2 m and a direction 30 degrees east of south. Alternatively, she could have kicked it to a second player standing directly in front of the goal along a displacement ry, who could have then kicked it to the goal along a displacement vector rx, as shown. Find the magnitudes and directions of rx and ndry. (a) Ty magnitude direction (b) magnitude direction 30.0° 90° -Select--- -Select--- ✓ W- m S Net

The normalized 1s wavefunction (n = 1, l = 0) of any one-electron atom or ion can be written as 100 (r, 0, 0) = R₁0(r)Y(0,0) = Z3 παρ 3 where Z is the nuclear charge (number of protons) and a = πmpe2 €0h² (a) Construct an integral expression, in r, 0, and that can be used to determine the expectation value for the hydrogen atom potential energy, (V), and evaluate the integrals over and p. Be mindful of the integration volume element. En == e (b) Define x = Zr/ao and use this form to simplify the integral over r and evaluate it (using the tabulated integral provided above) to obtain an expression for (V). Your result should include a factor of V(a). Use the potential energy operator V(r) = where e represents the electron charge and is the permittivity of a vacuum. Express your result in terms of V(a) (that is, express it as something times V(a)). (c) The energy levels of one-electron atoms and ions can be written in terms of a as Z Z²e² (2²72²2) V (ao) = (E) 8περαon2 Using this and your…

please help ASAP (& pls draw a picture), thank you!

A student walks 550 m [E], then 450 m [N30°W], and finally 350 m [S10°W]. Using the component method, find the resultant (total) displacement). Show your work and round your answer (magnitude and direction) to appropriate significant digits.

#1) Given the vectors A = (1, -3,5) and B = (6,-4, 2) find the following (make sure to use proper vector notation, you can use the given notation using parenthesis USI Just the answer from you calculator does not count, show your work.
