The Principle of Cross-Cutting tells us that a fault must be older than the rock it cuts. Cross-cutting in geology was formulated by Nicolas Steno, a Danish geologist in the mid-1600's. It is usually used in combination with radiometric age dating, which can tell the geologist how old the rock is.
Answer:
The Machine exerts a force of 9N.
Explanation:
Initial velocity (u) = 0 m/s
Final velocity (v) = 30 m/s
Time (t) = 0.5 s
Acceleration (a) = (v-u)/t
= (30-0)/0.5 m/s²
= 30/0.5 m/s²
= 60 m/s²
Mass = 0.15 kg
Force = Mass*Acceleration
= 0.15*60 N
= 9 N

Answer:
anxiety
Explanation:
