Answer:
1. A fossil that is widespread geographically but only occurs in one layer or a small number of layers of rock
2. Sediment deposited into water will spread in a horizontal and continuous sheet
3. Any undisturbed sequence of layered rocks has the oldest rock on the bottom and newest rock on the top
4. Study of fossils
5. Study of rock layers and the process that form them
Sorry if any of these are wrong
25x = 200*30
25x= 6000
x= 240
Answer:
A possible answer would be that chemical properties depend on phisical properties if and if only the phisical properties depend on the chemical ones ( see the laws of thermodinamics)
Answer: 0.024m
Explanation:
The first thing you must do is to find the speed of the swing when the bird leaves. Use conservation of momentum (p) to do this. p(i) = p(f)
P(i) = 0 (no motion) = p(f) = m*v + M*V where m&v are the bird and M&V are the wing
So V = -m*v/M = -0.052 x 2/0.153= -0.68m/s
Now apply conservation of energy. SO K bottom = 1/2*M*V^2 = U (potential) = M*g*h
h= V^2/(2*g) = 0..68^2/(2*9.8) = 0.024m
