In 1600, dr. william gilbert coined the term “electrica,” a word that gave rise to our word electricity.
what does this term “electrica” describe?

What type of light does this light bulb produce most (i. e. at what wavelength does the spectrum have maximum intensity)?

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?
