Acar slowing down for a stop sign is an example of? a. negative speed b. negative acceleration c. positive speed d. positive acceleration ( )

the correct choice is

b. negative acceleration

acceleration is given as rate of change of velocity and is given by the formula

a = (v - v₀)/t

where a = acceleration , v = final velocity, v₀ = initial velocity , t = time

as the car slows down , the final velocity is smaller than the initial velocity.

v < v₀

so (v - v₀) < 0

so acceleration = a =  (v - v₀)/t

since (v - v₀) < 0

hence a < 0

so the acceleration is negative

B. negative acceleration

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
