Answer:
The speed of elevator fast and slows down shows through the diagram.
Explanation:
Given that,
Amanda has just entered an elevator. The elevator rises and stops at the third floor.
Let us consider the elevator at rest then the speed will be zero.
When elevator start from rest then the speed increases with constant acceleration and near the third floor it slow down with constant deceleration and finally becomes at rest at third floor.
We need to draw the diagram distance and time
Using given data,
First, the displacement A to B will be increases fastly and B to C the displacement increases slowly slowly.
Hence, The speed of elevator fast and slows down shows through the diagram.
From Ohm's law: R = V / I
Resistance = (voltage) / (current)
Resistance = (70 volts) / (6 Amperes)
<em>Resistance = 11.67 ohms</em>
(We don't need to know the length, thickness, color, or cost of the wire.)

<h3>
Answer:</h3>
60 m
<h3>
Explanation:</h3>
<u>Concept Used:</u>
We know that the area under a velocity-time graph represents the Displacement of the body
<u>Displacement in the Last 6 seconds:</u>
To find the Displacement in the last 6 seconds, we will find the area under the graph between x = 4 and x = 10
We can see that the shape formed is a rectangle also shown in the given graph. So, the area of the rectangle is the Displacement of the car in the last 6 seconds
<u>Area of the Rectangle:</u>
From the graph, we know that the rectangle is 10 (m/s) tall and 6 (s) wide
Area of Rectangle= length*Breadth
replacing the values
Area = 10 (m/s) * 6 (s)
Area = 60 m
Hence, the car travelled 60 m in the last 6 seconds of the graph
