Answer:
C the Law of Superposition
Explanation:
Basically the law of Superposition is applied in this regard. The law states that "the oldest layer is on the bottom and the youngest layer is on top".
When we find fossils at a particular depth we can relatively date a rock based on the strata we find them. A fossil in place in bottom beds will be older than the one in the topmost layer. Fossils also succeed one another in a definite pattern according to the principle of fossil and fauna succession.
Answer: Phillipe wins the race
Explanation:
Given
Length of track=20 m
Velocity of Phillippe=2 m/s w.r.t sidewalk
Velocity of sidewalk=1.5 m/s
Rena velocity=2 m/s
Therefore absolute velocity of P is 2+1.5=3.5 m/s
Time taken by phillippe
=5.714+10=15.714 s
Time taken by rena
as the time taken by phillippe is less than rena therefore Phillippe wins the race.
Explanation:
T1 = 201k
T2 = 537k
C1 = 1220 m / s
C1/C2 =√(T1/T2)
C2 = C1×√(T2/T2)
C2 = 1220×√(537/201)
C2 = 1220 × √(179/67)
C2 = (1220√179)/(√69)
C2 = (1220√11993)/67 ≈ 1994.10924

Answer:
The distance is, y = 489.5 [m/s]
Explanation:
To solve this problem we can use the following equation of kinematics.
where:
Vf = final velocity = 98 [m/s]
Vi = initial velocity = 0
g = gravity acceleration = 9.81 [m/s^2]
y = distance [m]
(98^2) = 0 + (2*9.81*y)
Note: the positive sign of the equation means that the acceleration of gravity acts in the direction of the movement of the object.
9604 = 19.62*y
y = 489.5 [m/s]
