<span>To calculate the density, we must first calculate the volume of the object. For a rectangle, the volume is equal to V=l*w*h. In this case, V=22*13.5*12.5=3712.5 mm^3. Next we have to convert the mm^3 to mL using the conversion factor of 1 mm^3=.001 mL. To get mL, we set up the expression 3712.5 mm^3 * (.001mL/1mm^3) = 3.7125 mL. Finally, to get the density, we know density is mass over volume, so we set the expression p=m/V=2.5g/3.7125mL=.6734 which rounded to 3 significant figures is .673. The answer will be .673</span>
Answer:
<em></em>
<em>The lead shot-filled can experiences a greater force due to gravity because it contains more mass.</em>
Explanation:
The gravitational attractive force that acts on two different bodies on Earth depends on the body's masses. The greater the mass, the stronger the force of gravity acts on the body. The smaller the mass, the weaker the force of gravity acts on the body.
The can with the lead shot in it has a greater mass than that of the can that is filled with feathers. Therefore,<em> the can with the lead shot will experience a greater force due to gravitational attraction of the Earth</em> than that of the can that is filled with feathers.
Answer:
therefore, more kinetic energy! An object has the MOST kinetic energy when it's movement is the GREATEST.
Explanation:
PHysical properties are properties that do not involve changes in the molecular level. In this case, malleability and magnetism are physical.
Chemical properties involve changes to the substance at the molecular level or change its identity. In this case, reacting with oxygen and nonflammability is a chemical property.
