When you double the speed of your car, your braking distance quadruples. every time you double your speed, you multiply your braking distance by four.
We use the formula, to calculate the volume of water displaced by concrete canoe,
Here, W is the weight of concrete canoe and 
is the specific weight of water and its value is 
.
So,
.
Now the volume of water occupied in ultra lightweight kevlar canoe,
Here, w is weight of kevlar canoe.
So,
Thus, the volume of water displaced,
.
Hence, the volume of water displaced canoe compared to an ultra-lightweight kevlar canoe is 
Explanation:
An Example of push as a force would be to push on a swing. The force moves the swing in a particular direction and the harder that you push the further the swing will go.
An example of pull as a force would be opening a door. ...
An example of pressure as a force is when you push down on a pile of grapes. is this what you mean
Answer: Interneurons.
These interneurons transmit impulses to other neurons and thus form a part of the reflux arc.
Answer:
The planes’ acceleration from A to B is 500m/s^2
Explanation:
Given that the initial velocity u is 8000m/s
and also given the final velocity v=10,000 m/s
the time taken to move from A to B = 40 second
The acceleration is defined as the rate of change of velocity with time
we know that the expression for acceleration is given as
a=(v-u)/t
substituting our given data into the expression for a we have
a=(10000-8000)/40
a=2000/40
a=500m/s^2
The planes’ acceleration from A to B is 500m/s^2
