Answer:
1.05 N
Explanation:
K = 0.7 N/m
e = 1.5 m
F = ?
from Hooke's law of elasticity
F = Ke
= 0.7×1.5
= 1.05 N
Answer:
(D) Vf² = Vi² + 2ad
a = 2.269 m/s²
Explanation:
Given;
final velocity of the aircraft, Vf = 33 m/s
initial velocity of the aircraft, Vi = 0
distance traveled by the plane, d = 240 m
The acceleration of the plane is given by the following kinematic equation;
Vf² = Vi² + 2ad
where;
a is the acceleration;
Based on the given options, the correct option is "D".
Calculating the acceleration with the chosen equation;
Vf² = Vi² + 2ad
Vf² = 0+ 2ad
Vf² = 2ad
a = Vf² / 2d
a = (33)² / (2 x 240)
a = 2.269 m/s²
The first growth phase (G1): During the G1 stage, the cell doubles in size and doubles the number of organelles.
The synthesis phase (S): The DNA is replicated during this phase. In other words, an identical copy of all the cell’s DNA is made. This ensures that each new cell has a set of genetic material identical to that of the parental cell. This process is called DNA replication.
The second growth phase (G2): Proteins are synthesized that will help the cell divide. At the end of interphase, the cell is ready to enter mitosis.
Well the only relation they have is that they are both velocities.
The initial velocity of an object is the velocity it begins moving with. i. e if a ball is thrown its initial velocity is the velocity it has once it leaves the hand.
Terminal velocity is the maximum velocity an object can achieve when it is in free fall. i.e if a bowling ball is dropped from a plane, its velocity will increase until it reaches terminal velocity.
