Answer:
51.25 mph
Explanation:
Total distance= 100 miles + 30 miles + 75 miles=205 miles
Total time=2 hours+1 hour+1 hour= 4 hours
Average speed,
Answer:
<em>The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.</em>
I think it has 11 but i don't really know for sure.Correct me if i'm wrong.
Answer:
no it can not effect the speed of sound not shure tho
Answer:
a). 675J
b). 337.5J
c). 1012.5J
Explanation:
M = 6.0kg
V = 15.0m/s
a). Translational energy
E = ½ *mv²
E = ½ * 6 * 15²
E = 675J
b). Rotational kinetic energy K.E(rot) = Iw²
But moment of inertia of a cylinder (I) = ½Mr²
I = ½mr²
V = wr, r = v / w
K.E(rot) = ¼ mv²
K.E(rot) = ¼* 6 * 15²
K.E(rot) = 337.5J
Total energy of the system = K.E(rot) + Translational energy = 337.5 + 675
T.E = 1012.5J
