Calculate the second-order correction to the energy for the system described in problem 6.7 and calculate the ground-state wavefunction. account for the shape of the distortion caused by the perturbation. hint. use eqn 6.30 for the energy and eqn 6.27 for the wavefunction. the integrals involved are of the form cos ax sin bx dx da *sin ax sin bx dx = cos (a + b)x 2(a+b) cos ax sin bx dxcos(a-b)x 2(a-b) evaluate the sum over n numerically.

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c.m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?

Will mark brainliest! asap! ! 16) which of the clouds shown would indicate a possible future rain storm? a) b) c) d)

An astronaut floating in space is trying to use her jetpack to get back to her space station, but she is being pulled away by a nearby planet, as shown in the image below. her jetpack provides a constant thrust of 310 n. if she angles her jetpack in such a way that it cancels out the vertical force due to the planet's gravity, what is her net horizontal force? thaud 487 o a. 54.8 n toward the space station o b. 212.9 n toward the space station o c. 185.2 n toward the space station o d 956 n toward the space station
