Answer: Projectile
Explanation:
A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity.
Answer:
For definite motion in all links, two inputs to any 2 links are required
Explanation:
According to Grubler's equation
F = 3(n-1) - 2l - h
where
h= number of higherr pairs ;
l = number of lower joints ;
n = number of links ;
F = Degree of freedom ;
we have ,
n=5 ; l=5 ; h=0
By putting values we get,
F = 3(5-1) - 2*5 - 0
F = 12-10-0
F = 2
So, in order to yield definite motions in all links 2 inputs in 2 links are required.
Pipelines are a useful means of transporting oil because they offer low maintenance and dependable transportation for a narrow but important range of products.
<h3>What is a pipeline?</h3>
A pipeline is a system of connected pipelines that can be either underground or out in the environment. These pipelines are used to transport or distribute water, gas, and oil.
The options are attached
a. Pipelines provide jobs for consumers because of the resurgence of exploration and drilling in North America.
b. Pipelines are versatile, carrying more ton-miles than any other mode of transport over more than 2 million miles of pipeline.
c. Pipelines have more locations than water carriers.
d. Pipelines offer low maintenance and dependable transportation for a narrow but important range of products.
Thus, the correct option is d. Pipelines offer low maintenance and dependable transportation for a narrow but important range of products.

The friction loss in the system is 3.480 kilowatts.
<h2>Procedure - Friction loss through a pump</h2><h2 /><h3>Pump model</h3><h3 />
Let suppose that the pump within a distribution system is an open system at steady state, whose mass and energy balances are shown below:
<h3>Mass balance</h3>
(1)
(2)
(3)
<h3>Energy balance</h3>
(4)
Where:
- Inlet mass flow, in kilograms per second.
- Outlet mass flow, in kilograms per second. 
- Inlet volume flow, in cubic meters per second. 
- Outlet volume flow, in cubic meters per second. 
- Inlet specific volume, in cubic meters per kilogram.
- Outlet specific volume, in cubic meters per kilogram.
- Pump efficiency, no unit.
- Electric motor power, in kilowatts.
- Inlet specific enthalpy, in kilojoules per kilogram.
- Outlet specific enthalpy, in kilojoules per kilogram. 
- Work losses due to friction, in kilowatts.
<h3>Data from steam tables</h3>
From steam tables we get the following water properties at inlet and outlet:

Answer:
final pressure is 6847.41 kPa
Explanation:
given data:
as we can see all temperature are more than 100 degree, it mean this condition is refered to superheated stream
for ischoric process we know that
final pressure is 6847.41 kPa
