Does the particle travel in a straight line motion if so then it is particle
Answer:
The larger person will have to get a larger parachute. The answer is D
Explanation:
If the smaller person does nothing, the larger person subsequently accelerate for more time and with larger terminal velocity. In this case the person needs to do something so as to reduce the terminal velocity and can also effectively raise the air resistance. For this reason the person should get a bigger parachute. The air resistance in the opened parachute overwhelms the downward force of the gravity. Whereas the net force as well as the acceleration of the person is upward. The bigger parachute has the ability to grab the greater force. If the parachute, dragging force works in the opposite to that of the force of the gravity, hence the drag force slows the parachute decrease as they fall.
D it is only physical and not chemical
The Diprotodon apparently become extinct <u>20,000 years</u> ago.
<h3>Briefly explained</h3>
This question is in reference to the use of carbon 14 dating. We know the specific activity of a Australian marsupial. Based on the carbon 14 present. It's .61 PICO curie program. Modern carbon has a specific activity of 6.89 PICO curie program. So all we need to do then is use the first order integrated rate law to solve for the time that has elapsed with Both of these activities as part of the equation.
But before we can do that we need the decay constant for carbon 14, which we can get by dividing the half life Of carbon 14 into natural log of two. And we get 1.21 times 10 to give 14, 1 over years. So using the first order integrated rate law, the natural log of the activity at time, T divided by the activity Um at time zero represented by present day Will be equal to negative K. multiplied by T.
Little Algebraic rearrangement gives us an age of 20,000 years.

Answer:
No, the metal is not pure gold because density is equal to mass divided by volume and in this case we end up with about 15.3, making this metal less dense than gold.
