How much more kinetic energy does your car have when it changes its speed from 16 km per hour to 80 km per hour

Biology
1 answer:
USPshnik [31]3 years ago
4 0

Answer:

The correct answer would be - 25 times more.

Explanation:

The kinetic energy of a moving object increases with the increase in the speed of the object. It is evident that the kinetic energy of a moving object increases as the square of its velocity or speed. It means if a car moves with the speed of 32 km/hr has four times as much kinetic energy as the car moving with 16 km/hr.

Similarly, if a car changes its speed from 16 to 80 km/hr the kinetic energy will be -

= (80/16)^2

= (5)^2

= 25 times more.

Thus, the correct answer would be - 25 times.

Engulfing-phagocytic cells of innate immunity of vertebrates include _____. i) neutrophils ii) macrophages iii) dendritic cells
Kaylis [27]
The correct answer is I, II and III.
A phagocytic cell of a vertebrate organism is a critical component of the immune system. Its main action is to engulf and ingest foreign and possibly harmful particles, bacteria and dead or dying cells.

There are many different types of phagocytes and some of these include the macrophages, the neutrophils, and the dendritic cells.
The macrophages are phagocytic cells which can exit the bloodstream and detect pathogens outside the circulatory system.
Neutrophils contain toxic granules which can kill pathogens only by contact. Dendritic cells are located in the parts of the body which can easily be infected and can act as messengers who warn the body of threats. They do so by sending antigens as messages.

Why OR Why shouldnt we build power plants in france? PLEASE anwser question thoroughly!!!
IRINA_888 [86]

Answer:

We should not build more power plants in France because of a few reasons. reason 1 carbon emissions are terrible for our planet and we already have enough pollution. reason 2 we have a very low fuel supply as it is and using it up for things we don't need is not sufficient. Reason 3 is money. France is in a debt of 3,403.24 euros. we should not be spending what we don't have. These are the reasons why we should not build power plants in France.
