Elastic collisions in one dimension: A car of mass 1689 kg collides head-on with a parked truck of mass 2000 kg. Spring mounted bumpers ensure that the collision is essentially elastic. If the velocity of the truck is 17 km/h (in the same direction as the car’s initial velocity) after the collision, what was the initial speed of the car?

Use the R – R method to estimate the heart rate.

Unwanted marks on an ECG tracing that are not related to the heart’s electrical activity are known as:

Which type of electrode is most commonly used to perform an ECG?

When estimating the heart rate with the 6-second method, you locate 6 seconds on a rhythm strip, count the number of complexes, and multiply by:

Using the 1500 method, calculate the heart rate.

Unipolar leads include all the lead types except:

The Jewish holy book is the

The leads that make up a 12-lead ECG consist of:

Conservation of angular momentum: The angular momentum of a system remains constant
