Given :
A car slows down from -27.7 m/s to -10.9 m/s while undergoing a displacement of -105 m.
To Find :
The acceleration of the car.
Solution :
We know, by equation of motion :
Therefore, acceleration of the car is 3.088 m/s².
A is correct.
When the car stereo is turned on, the chemical energy from the battery is transformed to electrical energy to make the stereo on, then the energy is transformed to sound so you can year it.
Answer:
The finished product
Explanation:
-The Universal Systems Model is a general conceptualization on how a process can be represented.
-There are four basic elements to the systems model:
input-Inputs are the basic materials or resources that will be transformed to the output.
process-represents the operations that occur to transform the inputs to the desired outputs.
input -represents the desired result, outcome, or goal.
feedback-is the element of control.
Answer:
Answer:
43.4J
Explanation:
We know that
Work done = total heat energy
But work done is force x distance
=> F = 19 x8.6 = 163.4 J
So the total heat. Will be Heat of cube + heat of floor = 163.4J
So that heat of floor will now be
floor = 163.4 J - 120 J = 43.4 Joules
