Car batteries are rated by the following two numbers: (1) cranking amps=current the battery can produce for 30.0 seconds while maintaining a terminal voltage of at least 7.2 v and (2) reserve capacity=number of minutes the battery can produce a 25-a current while maintaining a terminal voltage of at least 10.5 v. one particular battery is advertised as having 905 cranking amps and a 155-minute reserve capacity. part a which of these two ratings represents the greater amount of energy delivered by the battery?

the word that best describes martin luther king jr.'s tone in the video is dignified

martin luther king, jr. was a social activist and baptist minister who played a key role in the american civil rights movement from the mid-1950s until his assassination in 1968. the video shows his manner and attitude having or showing a composed or serious manner that is worthy of respect so dignified is the correct answer

neither accurate nor precise.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
