Answer:
of silver would be required.
Explanation:
Dimensions of silver mas :
Length = l = 120.0 ft
breadth = b = 60.0 ft
Height = h = 0.33 ft
Volume of silver mass ,V= l × b × h
Density of silver,d = 
of silver would be required.
Answer: Rougher surfaces have more friction between them than smoother surfaces. That's why we put sand on icy sidewalks and roads. You can't slide as far across ice with shoes as you can on the blades of skates. The rougher surface of the soles of the shoes causes more friction and slows you down.<em> There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest.</em>

Answer:
The atomic radius gets smaller the farther right it appears on the
periodic table.
Explanation:
Number of protons is increasing across the period so electrostatic attraction between the positive nucleus and the valence electrons increases and electrons are drawn close to the positive nucleus. This increases nuclear charge and so atomic radii gets smaller.
Also, the atomic radii size also depend on Electron - electron repulsion and shielding of the outermost valence electrons by the inner-most energy levels for the positive nucleus and number of energy levels.
Across the period, the electron-electron repulsion does not increase but there is increasing nuclear charge. The valence electrons are added to same energy level so electron shielding of the positive nucleus by the inner electrons is the same across the period.
<span>Since friction is the only force dampening the acceleration of the puck, the acceleration of the puck in outer space will be equal to the acceleration on a hockey table where friction is negligible.</span>
