shows a car travelling at 30m/s on a level road. At this speed the car has to overcome a total force of 600N opposing the car (a) Calculate the distance travelled by the car in 10s.(b) State the value of the driving force produced by the engine for a steady speed of 30m/s (c) Explain why the car slows down when it climbs a hill, even though the driving force is unchanged (d) While on the level road and traveling at 30m/s, the driving force becomes zero. The mass of the car is 800kg. Calculate the deceleration of the car.

answer: i pick a

explanation:

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.  

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
