Answer:
a. Horizontal component v = 12 m/s
b. Magnitude of velocity v = 20.78 m / s
Explanation:
Vₓ = 12.0 m / s eastward
β = 30.0 °
So
a.
Vt = Vₐ - Vₓ
Vₐ = 0 i
Vt = 0i - 12.0 = - 12 m/s
b.
Vₙ = 12 / sin (30 °)
Vₙ = 24 m / s
Vₙ = 24 * con (30 °)
Vₙ = 20.78 m / s
Answer:
They are both correct.
Explanation:
The density of an object is defined as the ratio of its mass to its volume. This implies that the density of the object is both proportional to the mass and also to the volume of the object. John only mentioned mass which is correct. Linda mentioned the second variable on which density depends which is the volume of the object.
Hence considering the both statements objectively, one can say that they are both correct.

Centripetal force is defined as, "the force that is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation," while centrifugal force is defined as "the apparent force that is felt by an object moving in a curved path that acts outwardly away from the center of rotation," according to Merriam Webster Dictionary.
