In Physics, displacement is the distance and direction of the shortest path
from the starting point to the ending point, regardless of the path followed
to get there.
(2)(3)(2)=12⇒ D=M/V ⇒ D=94/12=7.8333(repeated) g/m³
Answer:
impact- equal
impulse- equal
momentum- equal
acceleration- the empty cart
Answer:
It reduces the melting point due to a defect in the arrangement of the crystal lattice.
Explanation:
The presence of impurities creates a disorderliness in the uniformity of the crystal structure. It lowers the melting point by a few degrees because it becomes easier to overcome the intermolecular force of attraction.
It makes the array of crystals disordered.
Lattice is a long chain three-dimensional arrangement of the molecules, atoms or ions in a crystal structure.
The question is asking to compute the annual cost of electricity to power a lamp post for 7.5 hrs per day with the following power, and base on my calculation, the answers would be the following:
