When rounding you look at the number right after the one you want to round. The tenth place is the one right after the decimal. If the number after it is more than five it goes up by one, it it's less than five it stays the same. So since the number after the 8 is a 3 it stays the same.
The answer is 7.8
Answer and Explanation:
1. Evaluate the function x(t) at t=0.5
2. The period of motion T can be calculated as:
Where:
So:
3. The angular frequency can be expressed as:
Solving for k:
4. Find the derivate of x(t):
Now, the sine function reach its maximum value at π/2 so:
Solving for t:
Evaluating v(t) for 0.6603981634:
So the maximum speed of the block is:
In the negative direction of x-axis
5. The force is given by:
The cosine function reach its maximum value at 2π so:
Solving for t:
Evaluating x(t) for 3.016592654:
Therefore the the maximum force on the block is:
Answer:
incomplete question, resistor must be there
Explanation:
Both
Explanation: the thing is you will adapt to your environment in order to survive I know this because if you live in a environment where a whole bunch of people get sick, you will get a stronger immune system when you are born.Your genes also come from you family members to. That is why the answer is both. Have a nice day!
Answer:
Explanation:
Given:
- mass of the object,
- spring constant,
- compression in the spring,
<u>Now the force on the spring on releasing the compression:</u>
<u>Now the acceleration due to this force:</u>
