Nina [5.8K]2 years ago
4 0

Answer:

science is define as the study of physics, chemistry, biology, geology and astronomy. science is very important in our daily life.we study science for knowing the knowledge about biological and chemical and many other aspects.without science it is impossible to live our daily life.science is used in each and every steps.

Explanation:

There are many more benefits that we are getting and going to get . Science has already discovered many things ,that we didn't expect efore.And also in progress to discover new things.Science has developed a new type of antivirus that protect us from different virus.Has made different medicine that recover a people. So it is very useful in our life.

A(n) _____ satellite system employs many satellites, each in an orbit at an altitude of less than 1,000 miles.
vlabodo [156]

Answer:

The correct answer is a Low earth orbit.

Explanation:

A low earth orbit can be understood as an earth orbit with an altitude of 1,000 miles or less. It is a satellite sustem that employs many satelites, in fact, most man-made objects that are currently in outer-space are part of this low earth orbit. (LEO).

The most famous LEO satellite system is the one from planet earth. Almost every space flight that human beings have ever done are done in LEO, and every spacial station is located in this zone.

In conclusion, A low earth orbit satellite system employs many satellites, each in an orbit at an altitude of less than 1,000 miles.

2.)
Oduvanchick [21]

Answer:

-22.7 m/s^2

Explanation:

This is a uniformly accelerated motion, so we can determine the deceleration of the car by using a suvat equation:

v^2-u^2=2as

where

v is the final velocity

u is the initial velocity

a is the acceleration

s is the distance covered

For the car in this problem,

u = 27.8 m/s

v = 0

s = 17 m

Solving for a, we find the acceleration:

a=\frac{v^2-u^2}{2s}=\frac{0-27.8^2}{2(17)}=-22.7 m/s^2

Describe difference between instantaneous velocity and average velocity
Alexxandr [17]

Answer:

The instantaneous velocity is the specific rate of change of position (or displacement) with respect to time at a single point (x,t) , while average velocity is the average rate of change of position (or displacement) with respect to time over an interval.Average velocity : Average velocity of a body is defined as the change in position or displacement (Δx) divided by time interval (Δt) in which that displacement occurs.

Instantaneous velocity : The instantaneous velocity of a body is the velocity of the body at any instant of time or at any point of its path .

velocity can be positive , negative or zero.

By studying speed and velocity we come to the result that at any time interval average speed of an object is equal or more than the average but instantaneous speed is equal to instantaneous velocity.
