A. Molecular solids tend to have lower melting points than Ionic so it would be Ionic if it weren't for Molecular.
Answer:
v = 10 m/s
Explanation:
Given,
Length of the vine, l = 36 m
Angle of inclination = 31.0◦ with the vertical
acceleration due to gravity = 9.81 m/s²
Using Conservation of energy
KE = PE
v = 10 m/s
Hence, the speed of the swing is equal to 10 m/s
Answer:
A. on both mass and velocity
Explanation:
Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. The equation illustrates that momentum is directly proportional to an object's mass and directly proportional to the object's velocity.
