Answer to Problem 1RQ
An atom is composed with nucleus and electrons in a surrounding cloud. Thus inside of an atom is empty
Explanation of Solution
An atom is made up of electron proton and neutron. The proton and neutron together formed the nucleus of the atom. And the electron is in a surrounding cloud.
As an example, considering the simplest type atom hydrogen which is having one proton and one electron. The proton is having diameter of about
The volume of nucleus is in the range of

- Problem Eight. A snowmobile is originally at the point with position vector 31.1 m at 95.5° counterclockwise from the x-axis, moving with velocity 4.89 m/s at 40.0°. It moves with constant acceleration 1.73 m/s² at 200°. After 5.00 s have elapsed, find the following. 9.) The velocity vector in m/s.

One of the teachers kicks the ball back up to the children as shown in the figure below. The playground is 6.10 m above the parking lot, and the school building's vertical wall is h = 7.40 m high, forming a 1.30 m high railing around the playground. The ball is launched at an angle of 8 = 53.0° above the horizontal at a point d = 24.0 m from the base of the building wall. The ball takes 2.20 s to reach a point vertically above the wall. (Due to the nature of this problem, do not use rounded intermediate values-including answers submitted in WebAssign-in your calculations.) (a) Find the speed (in m/s) at which the ball was launched. 18.1 m/s (b) Find the vertical distance (in m) by which the ball clears the wall. 0.73 ✓ m (c) Find the horizontal distance (in m) from the wall to the point on the roof where the ball lands. 2.68 m (d) What If?

- It is not possible to see very small objects, such as viruses, using an ordinary light microscope. An electron microscope can view such objects using an electron beam instead of a light beam. Electron microscopy has proved invaluable for investigations of viruses, cell membranes and subcellular structures, bacterial surfaces, visual receptors, chloroplasts, and the contractile properties of muscles. The "lenses" of an electron microscope consist of electric and magnetic fields that control the electron beam. As an example of the manipulation of an electron beam, consider an electron traveling away from the origin along the x axis in the xy plane with initial velocity ₁ = vi. As it passes through the region x = 0 to x=d, the electron experiences acceleration a = ai +a, where a and a, are constants. For the case v, = 1.67 x 107 m/s, ax = 8.51 x 1014 m/s², and a = 1.50 x 10¹5 m/s², determine the following at x = d = 0.0100 m.
