Answer:

Total displacement will be 1120 meters.

Explanation:

To calculate displacement from the velocity, need to take integral of velocity for a one time period.

x=\int\limits^7_{-1} {t^3-15*t^2} \, dt\\x=\int\limits^7_{-1} {t^3} \, dt-\int\limits^7_{-1} {15*t^2} \, dt\\x=600-1720\\x=-1120

The total displacement is 1120 meter in negative way.

If a horse gallops one meter per second how for can it travel 1 minute
Tasya [4]
SOLUTION:

1 minute = 60 seconds

1 second = 1 metre

1 × 60 = 1 × 60

60 seconds = 60 metres

1 minute = 60 metres

Therefore, the horse can gallop / travel 60 metres in 1 minute.

Hope this helps! :)

How can you tell if one object has more mass than another does, on a planet without gravity
Serhud [2]

an object is more dense if there is more weight in the same area, its because of the amount of particles and the weight of the particles. eg, 1cm cubed of gold would weigh alot more than 1cm cubed polystyrene, so gold is more dense

Who pioneered the use of galvanoplastic compounds for preserving footprints and ballistics?
alukav5142 [94]

Answer:

Option D (Alphonse Bertillon) is the correct response.

Explanation:

  • He seems to have been a policeman turned biometrics expert from France. Forensic techniques such as forensic record analysis were developed by Bertillon.
  • To retain proof, he always pioneered or developed the use of such galvanoplastic compounds as molds for footsteps as well as ballistics. To research physical changes with age, Bertillon has developed a method focused on images of almost the same person’s performance.

All those other choices weren’t connected to the instance offered. So, the best one is the one described.
