Answer and Explanation:

A line of dominoes falling i.e. falling one by one is a prime example of the energy transfer. Energy transfer is referred to as or known as the conversion of one type of energy into the another type, or also referred to as the movement of the energy from one environment to the another. Hence, the answer is <em>energy transfer.</em>

When a moving car is brought to a stop with the brakes, its acceleration vector is 29. (a) in the same direction as its velocity

professor190 [17]

To develop this problem we will apply the concepts related to the kinematic equations of motion, specifically that of acceleration. Acceleration can be defined as the change of speed in an instant of time, mathematically this is

$\vec{a} = \frac{\vec{v_2}-\vec{v_1}}{\Delta t}$

If a mobile is decreasing its speed (it is slowing down), then its acceleration is in the opposite direction to the movement. This would imply that the acceleration vector is opposite to the velocity vector.

Therefore the correct answer is B.

The maximum speed limit on interstate 10 is 75 miles per hour. how many meters per second is this

Dvinal [7]

Answer:

Explanation:

Given the maximum speed limit on interstate 10 as 75 miles per hour, to get the speed in meter per seconds, we need to convert the given speed to meter per seconds.

Using the conversion 1 mile = 1609.34m and 1 hour = 3600 seconds

75 miles perhour = 75miles/1 hour

75miles/1 hour (in m/s) = 75miles*1609.34m* 1 hour/1mile * 1 hour * 3600s *

= 75 *1609.34m* 1 /1 * 1 * 3600s

= 120,700.5m/3600s

= 33.53m/s

<em>Hence the maximum speed limit on interstate 10 in metre per seconds is 33.53m/s</em>
