What else can I help you with?
Which instrument can be used to measure the time taken for the pendulum to make 20 oscillations?
A stopwatch or a timer can be used to measure the time taken for the pendulum to make 20 oscillations. Start the timer when the pendulum starts swinging and stop it when it completes 20 oscillations to determine the time elapsed.
What does a stop watch measure?
Time. The time taken between starting it and stopping it.
What is difference between a mechanical stopwatch and an electronic stopwatch?
A mechanical stopwatch can measure a time interval of up to 0.1 seconds. It has a knob that is used to wind the spring that powers the watch. It can also be used as a start-stop and reset button. The watch starts when the knob is pressed once. The Electronic Stopwatch keeps time for an unlimited number of splits and registers 1/100th for the first 30 seconds, and 1 second . thereafter for up to 24 hours. It includes a programmable alarm, and displays the current date, time and month.
When the skydiver steps out of the helicopter someone who's watching starts a stopwatch. So the time is zero as the skydiver steps out of the plane. What is the skydiver's downward velocity at that?
At the moment the skydiver exits the helicopter, their downward velocity is initially zero. As they fall due to gravity, their velocity will increase over time.
Why is it important to stop heating when the temperature starts increasing?
Stopping heating when the temperature starts increasing is important to prevent overheating, burning, or damaging the material being heated. It can also help avoid safety hazards and maintain control over the cooking process.
The halflife of Na24 is 15 hours When there are 1000 atoms of Na24 in a sample a scientist starts a stopwatch The scientist stops the stopwatch at 45 hours there are atoms of Na24 rema?
There will be 125 atoms of Na24 remaining in the sample after 45 hours. This calculation is based on the fact that after 3 half-lives (45 hours/15 hours per half-life), the original 1000 atoms would have reduced by a factor of 2 three times, resulting in 1000/2/2/2 = 125 atoms remaining.
The half life of Au198 is 2 7 days When there are 800 atoms of Au198 in a sample a scientist starts a stopwatch The scientist stops the stopwatch at 8 1 days there are atoms of Au198 rema?
At 8.1 days, 400 atoms of Au198 would remain in the sample. This is because after 8.1 days, two half-lives of Au198 have passed, reducing the initial 800 atoms to 400.
The half-life of Na-24 is 15 hours When there are 1000 atoms of Na-24 in a sample a scientist starts a stopwatch The scientist stops the stopwatch at 45 hours there are atoms of Na-24 remaining?
Based on the half-life of Na-24, after 1 half-life (15 hours), there would be 500 atoms remaining. After 2 half-lives (30 hours), there would be 250 atoms remaining. After 3 half-lives (45 hours), there would be 125 atoms remaining in the sample.
The half-life of Au-198 is 2.7 days When there are 800 atoms of Au-198 in a sample a scientist starts a stopwatch The scientist stops the stopwatch at 8.1 days how many atoms of Au-198 remaining?
After 8.1 days, three half-lives have passed (8.1 days / 2.7 days = 3). With each half-life, the number of atoms is halved. Therefore, starting with 800 atoms, after three half-lives there would be 800 / 2 / 2 / 2 = 100 atoms remaining.
What is the greatest length of time measured on a stopwatch?
There is no upper limit; when the stopwatch reaches the largest number of seconds it can count, it simply starts over. It is your job to count the number of times it starts over. Most digital stopwatches can time up to 20 hours, resetting after 19:59:59.99.
What is an ocupation that starts with k?
Kraft scientist
Who is a scientist that starts with M?
· Marie Curie
What type of scientist starts with the letter a?
archaeologist
How do you build a mechanical stopwatch?
To make a mechanical stopwatch, you’ll need gears, a spring, and an escapement that ticks evenly. The spring powers the gear train, the escapement keeps time steady, and a button starts and stops the movement. Adjust for smooth operation.
Scientist whose name starts with a?
Albert Einstein
A uranium235 sample starts with 200 atoms and 700 million years later there are 100 atoms What is the halflife of uranium235?
700 milliion years. The definition of half-life is the period of time during which one-half of the atoms of an element undergo decay into other elements.
What scientist last name starts with an ''b''?
Nils Bohr
