What’s the question? I’d isn’t understand explain
<span>The equation for momentum is p = mv, where m is the mass of the object and v is its velocity. Through conservation of momentum, we know that the momentum of the rifle must be of the same magnitude and opposite direction to that of the bullet. Thus we can form two expressions for the respective momenta, set them equal, and solve for the recoil speed of the rifle.
718*0.0159 = vr*5.05 where vr is the rifle recoil speed.
Solving for vr = 718*0.0159/5.05 = 2.26 meters/second.</span>

do u have a photo that comes w/ this? so i could help more :) ?
Explanation:
<span>For hydrolysis to monosaccharides, one molecule of a disaccharide needs only one molecule of water.
C12H22O11 (sucrose) + H2O = C6H12O6 (glucose) + C6H12O6 (fructose)
Structurally, a disaccharide molecule may be viewed as a product formed by the condensation of two molecules of monosaccharides with the elimination of a water molecule. So, only one H2O molecule is needed for the reverse process.</span>
First calculate the volume of the rectangular prism by multiplying its length, width and height. The volume of the prism is 8 cm^3. Since density is known to be mass over volume, just multiply the given density with the volume. The mass of the prism then is 960 grams.
and Since density is the ratio of the substance's mass to its volume,
Density = Mass/Volume
Mass = Density*Volume
The volume of a rectangular prism is:
V = LWH = 4×2×1 = 8 cm³
Mass = (120 g/cm³)(8 cm³)
<span>Mass = 960 grams</span>
