A driver sets out on a journey. for the first half of the distance she drives at the leisurely pace of 30 mi/h; during the secon

Gemiola [76]

The average speed of a moving object is the rate of change of a certain distance with respect with time. It is equal to the total distance that was traveled by the object over the total time it takes to travel that distance. For this problem we need to assume that the total distance that was traveled would be equal to 120 miles. So, for the first half of the distance or 60 miles at a speed of 30 miles per hour, the time taken would be two hours. For the remaining 60 miles at a speed of 60 miles per hour, 1 hour is total time traveled. So, we calculate the average speed as follows:

Average speed = total distance / total time
Average speed = 120 miles / 2 hr + 1 hr
Average speed = 40 mi / hr

Heat energy is transferred by conduction whenever molecules?

Rama09 [41]

The heat transfer by conduction occurs due to the collision between the molecules in the substance.

Explanation:

The heat transfer between the substances or in a medium is carried out by means of three methods.

Conduction
Convection
Radiation

The conduction is the process of transfer of heat within the substance by transferring the heat one by one to each molecule throughout the substance by colliding with the neighboring molecule. This method prevails in the transfer of heat in the solids.

The convection is the process of transfer of heat in which the source of heat is used to heat a particular bunch of molecules or a layer of the substance and then that layer moves away from the source and lets other molecule to come close to the layer. This method of heating is used in liquids.

The radiation is the process of transfer of heat in the medium by means of the energy carried by the radiation. This process of heating is used for the heating of the gases in the medium.

Thus, The heat transfer by conduction occurs due to the collision between the molecules in the substance.

The magnitude of a negative of a vector is negative. O True O False

Paha777 [63]

Answer:

The given statement is false.

Explanation:

For any negative vector

$\overrightarrow{r}=-x\widehat{i}-y\widehat{j}$

The magnitude of the vector is given by

$|r|=\sqrt{(-x)^{2}+(-y)^{2}}\\\\|r|=\sqrt{x^2+y^2}$

As we know that square root of any quantity cannot be negative thus we conclude that the right hand term in the above expression cannot be negative hence we conclude that magnitude of any vector cannot be negative.
