A 7.77 kg mass is moving due west at 7.77 m/s. A second mass of 8.88 kg is moving due south at 8.88 m/s. What is the magnitude o
masya89 [10]

Answer:

8.362m/s

Explanation:

Given data

Mass m1= 7.77kg

Velocity v1= 7.77m/s

Mass m2= 8.88kg

Velocity v2= 8.88m/s

Apply the law of conservation of momentum for inelastic collision we have

m1v1+m2v2= (m+m2)V

7.77*7.77+ 8.88*8.88= (7.77+8.88)V

60.3729+78.8544= 16.65V

139.2273= 16.65V

Divide both sides by 16.65

V= 139.2273/16.65

V= 8.362m/s

Hence the final velocity is 8.362m/s

What disadvantages does a conveyor belt have?
leva [86]

Answer:1. Belt Conveyor System

Advantages

One of the cheapest conveyors

Simple and easy to use

Can have changes in elevation

Can be loaded from any place along the belt

Disadvantages

The simplicity means very limited features

Belt can be difficult to clean and generally does not leave a very successful result

Sticky material can get stuck on the belt and transfer to the return side, the rolls, idlers and pulleys

2. Roller Conveyor System

Advantages

Can use gravity for moving the product on a decline angle

No power means less cost and more environmentally friendly

Quite modular andcan be utilized in many ways

Fairly low maintenance

Disadvantages

Products may end up being damaged when moved by gravity

Heavy and therefore not very portable

No control of conveyor speed

3. Powered Roller Conveyor System

Advantages

Effective horizontal transportation over a longer distance

The speed and also the process can be easily controlled and the risk for damage is reduced as the parts never touch

The small zones of the system are powered independently and can be set up to run only when an item is present

If a motor breaks down, it will only stop one zone

Disadvantages

Noisier than many other conveyors

More expensive than other conveyors

Not as flexible with what type of items it can handle

4. Overhead Conveyor System

Advantages

Can utilize the space overhead maximizing the full capacity of a facility

Buffer stores of serial produced components can be stored and sequentially delivered to a pick point when required

Full production systems can be created in a friction drive overhead conveyor using multi drive technology offering speed differentials

Lower operating costs and known for being very safe

Disadvantages

Generally more expensive than a floor based conveyor system

If breaking down, it can be more challenging to repair if no foresight at the planning stage and installation for maintenance

If chain based, it tends to need continual lubrication meaning grease or oil might drop from the system

As you can see, there are pros and cons for each conveyor system. One of the most important things to consider is therefore your specific business and the type of material you wish to transport. Some of the material’s characteristics to consider are size, weight, and density. But key considerations should also be the size of the system compared to the size of your facility as well as the environment itself – temperature, humidity and vibration for example. Feel free to contact us and we’ll help you determine any potential risks and possible countermeasures in order to create the safest and most effective environment.

deff fn [24]

Answer:

B. the force of the spring pulling on you

Explanation:

The independent variable is the variable that is being controlled.  In this case, the distance the spring is stretched.

The dependent variable is the variable that is being measured.  In this case, the force of the spring pulling back.

A negative charge, q1, of 6 µC is 0. 002 m north of a positive charge, q2, of 3 µC. What is the magnitude and direction of the e
prohojiy [21]

Force on the particle is defined as the application of the force field of one particle on another particle. The magnitude and direction of the electrical force will be 4.05×10⁴N towards the north.

<h3>What is electrical force?</h3>

Force on the particle is defined as the application of the force field of one particle on another particle. It is a type of virtual force.

The given data in the problem is

q₁ is the negative charge = 6 µC=6×10⁻⁶ C

q₂ is the positive charge = 3 µC=3×10⁻⁶ C

r is the distance between the charges=0.002 m

F_E is the electric force =?

The value of electric force will be;

\rm F_E= \frac{Kq_1q_2}{r^2} \\\\ F_E= \frac{9\times 10^9\times 6\times 10^{-6}\times3\times10^{-6}}{(0.002)^2}\\\\ \rm F_E=4.05\times10^4\;N

Hence the magnitude and direction of the electrical force will be 4.05×10⁴N towards the north.
