When you’re driving on the freeway it’s necessary to keep your foot on the accelerator to keep the car moving at a constant spee
aalyn [17]

When you’re driving on the freeway it’s necessary to keep your foot on the accelerator to keep the car moving at a constant speed. In this situation  the net force on the car is zero.

The rate of change of the velocity of a particle with respect to time is called its acceleration. If the velocity of the particle changes at a constant rate, then this rate is called the constant acceleration.

Since we are using metres and seconds as our basic units, we will measure acceleration in metres per second per second. This will be abbreviated as m/s². It is also commonly abbreviated as ms⁻².

For example, if the velocity of a particle moving in a straight line changes uniformly (at a constant rate of change) from 2 m/s to 5 m/s over one second, then its constant acceleration is 3 m/s².

Zero acceleration means constant velocity. Also to be noticed is that the definition of acceleration does not involve any information about forces. Acceleration is a kinematic quantity. Irrespective of what forces are acting, if the velocity is constant, the acceleration is zero.

irina1246 [14]

Answer:

ventriculoperitoneal      

Explanation:

A VP or ventriculoperitoneal shunt is a medical equipment or a device which is used to relieve pressure from the brain that is caused by the accumulation of fluid in the brain. Ventriculoperitoneal shunting is a medical procedure that is primarily used to treat a condition  known as hydrocephalus. This condition occurs when the more cerebrospinal fluid (CSF) gets collected in the  ventricles of the brain than required.

Hence the answer is ---

ventriculoperitoneal

The displacement of a moving object in given interval of time is zero . Would the distance travelled by the object also be zero.
kirill [66]





Hi Pupil Here's Your answer ::




➡➡➡➡➡➡➡➡➡➡➡➡➡



No, on a circle in going from one point around circular path the displacement is zero but the distance covered is equal to the circumference of the circle.

i.e.


2\pi r

The steps of mieosis
lbvjy [14]

Answer:

Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
