A tourist bus is carrying passengers from the bottom of a hill to the top. The people, the bus, and the luggage can be analyzed

as a single machine structure system . The total amount of energy in the system decreases increases remains the same as the bus travels. This situation happens because some of the kinetic energy changes to kinetic potential thermal energy because of friction between the tires and the road.

Answer:

A tourist bus is carrying passengers from the bottom of a hill to the top. The people, the bus, and the luggage can be analyzed as a single <em>system.</em> The total amount of energy in the system <em>decreases </em>as the bus travels. his situation happens because some of the kinetic energy changes to <em>thermal </em>energy because of friction between the tires and the road.

Answer:

The total amount of energy in the system decreases as the bus travels. This situation happens because some of the kinetic energy changes to thermal energy because of friction between the tires and the road.

Explanation:

In an isolated system (= no external forces acting on it), the mechanical energy of the system remains constant:

E=U+K=const.

where U is the potential energy and K is the kinetic energy.

In this case, however, the system is not isolated. In fact, there is an external force acting on the bus: the force of friction. The force of friction acts against the motion of the bus, therefore the bus loses part of its energy, and its total energy decreases. This energy is converted into thermal energy (motion of the molecules of the surface of the road and of the wheel)

Which type of communications equipment functions as a radio receiver and searches across several frequencies?
krok68 [10]

A <u>scanner</u> is a type of communications equipment that functions as a radio receiver and searches across several frequencies.

A scanner is a kind of a radio receiver that has the ability to receive multiple signals.

There are three modes which a scanner uses for acting as a radio receiver. The scan mode of the radio receiver constantly changes frequencies that helps in transmissions. There is also a manual scan mode that allows the users to search for their interested frequencies. The search mode allows the users to search through two sets of frequencies.

A scanner is a type of communication equipment that is easy to use with various features such as the volume, numeric keypad,  trunk tracking etc.

A stationary speed gun emits a microwave beam at 2.10*10^10Hz. It reflects off a car and returns 1030 Hz higher. What is the spe
lana [24]

Answer: V = 15 m/s

Explanation:

As  stationary speed gun emits a microwave beam at 2.10*10^10Hz. It reflects off a car and returns 1030 Hz higher. The observed frequency the car will be experiencing will be addition of the two frequency. That is,

F = 2.1 × 10^10 + 1030 = 2.100000103×10^10Hz

Using doppler effect formula

F = C/ ( C - V) × f

Where

F = observed frequency

f = source frequency

C = speed of light = 3×10^8

V = speed of the car

Substitute all the parameters into the formula

2.100000103×10^10 = 3×10^8/(3×10^8 -V) × 2.1×10^10

2.100000103×10^10/2.1×10^10 = 3×108/(3×10^8 - V)

1.000000049 = 3×10^8/(3×10^8 - V)

Cross multiply

300000014.7 - 1.000000049V = 3×10^8

Collect the like terms

1.000000049V = 14.71429

Make V the subject of formula

V = 14.71429/1.000000049

V = 14.7 m/s

The speed of the car is 15 m/s approximately

What is an example of a negative incentive for producers
Hatshy [7]

An example of a negative incentive for producers is the sharp increase in production costs. Producers are the one who manage the production costs and even the production budget. Anything that relates the production department is entitled to the management of production producers.

There is what we called positive and negative incentives and both of these can affect consumers and producers. Positive incentives are those situations which will give a certain outcome that will benefit the producers, for example, during the peak season there will be a high demand of products, and this gives the chance of producers to demand a higher price from the consumers, in this situation, there will be a big chance of increase sales.  A sharp increase in production costs is a loss for the producers.  If there will be an increase in production costs, the budget will be greatly affective and even though it is not a peak season, there’s a big chance also to increase prices which we know, consumers are not fond of.
