Hz is the measurement of a frequency equal to one cycle per second. since this wave shows 9 peaks and valleys or "cycles" your answer would be 3 Hz due to the fact that the length of time is 3 seconds. (3 cycles per second X 3 seconds.)
Answer:
<h2>The answer is 100 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
<h3>Force = mass × acceleration</h3>
From the question
mass = 10 kg
acceleration = 10 m/s²
We have
Force = 10 × 10
We have the final answer as
<h3>100 N</h3>
Hope this helps you
Answer:
Compositional Layers
The Earth has different compositional and mechanical layers. Compositional layers are determined by their components, while mechanical layers are determined by their physical properties. The outermost solid layer of a rocky planet or natural satellite.
Answer:
I would say around the 11th or 12th hour
Explanation:
seeing as the question calls for ALL of earth's history compressed into 12 hours the timeline should be similar to this: Earth was born at midnight, at around 2-3 AM land masses form, Right after that, life begins, For around 8 hours (11 PM) life is confined in water, right after that we have plants, 22 minutes later we have dinosaurs, 22 minutes later we have mammals, 5 minutes later dinosaurs are extinct, 6 minutes later we have people. So it's most likely the 12th hour. I hope this helps.
