Construct a graph of position versus time for the motion of a dog, using the data in the table below. Explain how the graph indi
cates that the dog is moving at a constant speed.
1 answer:
Answer:
The dog is moving at a constant speed
Explanation:
Given that,
Position : 5, 10, 15, 20, 25
Time = 5. 10, 15, 20, 25
We need to draw a position time graph
Using given data
A graph of position and time shows the speed.
According to graph,
The graph indicates that the dog is moving at a constant speed because the graph is straight line.
Hence, The dog is moving at a constant speed

Explanation:
Given :
Electric potential in the region is ,
We need to find the electric field .
We know , electric field , { Here r is distance }
In coordinate system ,
{
is partial derivative }
Putting all values we get ,
Hence , this is the required solution.
Answer:
The percentage of the weight supported by the front wheel is A= 19.82 %
Explanation:
From the question we are told that
The center of gravity of the plane to its nose is
The distance of the front wheel of the plane to its nose is
The distance of the main wheel of the plane to its nose is
At equilibrium the Torque about the nose of the airplane is mathematically represented as
Where m is the mass of the airplane
is the weight of the airplane supported by the main wheel
So
Substituting values
Now the weight supported at the frontal wheel is mathematically evaluated as
Substituting values
Now the weight of the airplane is = mg
Thus percentage of this weight supported by the front wheel is 19.82 %
