A lens of focal length 10.0 cm forms an image 11.0 cm from the
lens. What was the object
distance?
(Unit = cm)

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving
