Two warships were moving toward each other in the same straight line at 50 km/h and 89 km/h respectively. One of the ships fired a shell toward the other when the distance to it was 4.2 km. Given that the shell's horizontal velocity relative to the first ship was 211 km/h, how long did it take for the shell to hit the second ship?

The act of moving from one place to another. a. locomotor b. aerobic c. stationary d. static

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?

Selma made a diagram to compare convection and radiation. which label belongs in the area marked x? must involve temperature differences between substances or objects only occurs when molecules are in direct contact involves the movement of fluids based on density differences can occur where there is little or no matter
