A runner is jogging in a straight line at a steady Vr= 3.4km/hr. When the runner is L=8km from the finish line, a bird begins fl

Lynna [10]

Answer:

The cumulative distance that the bird travel is 13.33 Km

Explanation:

Given that,

Velocity of runner = 3.4 km/hr

Distance = 8 km

Velocity of bird = 17 km/hr

Let x is the distance from the origin where the runner run into the bird

We need to calculate the value of x

Using time of runner and bird

$t_{r}=t_{b}$

$\dfrac{d_{r}}{v_{r}}=\dfrac{d_{b}}{v_{b}}$

Put the value into the formula

$\dfrac{x}{3.4}=\dfrac{8+(8-x)}{17}$

$17x=3.4\times8+3.4(8-x)$

$17x=27.2+27.2-3.4x$

$17x+3.4x=54.4$

$x=\dfrac{54.4}{20.4}$

$x=2.67$

We need to calculate the cumulative distance that the bird travel

Using distance of bird

$d_{b}=16-x$

Put the value into the formula

$d_{b}=16-2.67$

$d_{b}=13.33\ km$

Hence, The cumulative distance that the bird travel is 13.33 Km

The management information base (MIB) is a repository of data maintained at a managing entity site, providing the network manager with a centralized, quick-to-query database regarding current network status is considered as false

Explanation:

The management information system is a formal description set of network objects that is managed by using the Simple Network management protocol.

The performance of network is measured based on the delay throughput and packet loss. There are management information system for more related entities that are managed by the companies.

777dan777 [17]

Answer:

330 m/s

Explanation:

The sound wave has to travel TO the cliff AND back = 2 * 49.5 = 99 m

magnitude of velocity = distance / time = 99m / .3 s = 330 m/s

Tracy makes a list of energy transformations that occur as an engine runs to power a car. 1. chemical energy transforms into the

alex41 [277]

Transformation 3 should Tracy removed from the list. Chemical energy transforms into gravitational potential energy.

<h3> What is the law of conservation of energy?</h3>

According to the Law of Conservation of Energy, energy can neither be created nor destroyed, but it can be transferred from one form to another.

The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.

Transformations that occur as an engine runs to power a car is;

1. Chemical energy of fuel transforms into thermal energy.

2. Thermal energy transforms into electrical energy used to lighten the bulb in a car.

3. Thermal energy transforms into kinetic energy to help to run the car.

Chemical energy transforms into gravitational potential energy is the incorrect energy transformation.

Hence, transformation 3 should Tracy removed from the list.
