Scanning Power (4x) = mm; mm X 1000 = μm Low Power (10x) = mm; mm X 1000 = μm High power (40x) = mm; mm X 1000 = μm Which objective lens (on the microscopes in the lab) provides the largest field of view? Which objective lens (on the microscopes in the lab) provides the smallest field of view? Is field of view directly or inversely related to magnification?

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.

Find the mass by adding the numbers from the three sliders

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?
