The correct answer is True.
Explanation
When we must solve a multiple-choice test or exam, in most cases, we are asked to select only one choice from four or more options. This means we need to know which is the correct answer from the options given to obtain a good grade. Due to this, we must be very precise when responding and paying attention to details because many times the answers are very similar, but only one contains all the elements that answer the question.
One of the most used methods to do this is "eliminating answers" this means we discard answers that we are sure are not possible answers by crossing out these and leaving only the correct answer or a few possible correct answers, in this case, we will need to analyze the remaining answers to select the most appropriate. So, the correct answer is True.
Answer:
public class Triangle
{
public static void main( String[] args )
{
show( 5 );
}
public static void show( int n )
{
int i,j,k;
for (i = 0; i < n - 1; i++ )
{
for (j = 0; j < i; j++ )
{
System.out.print( " " );
}
for (k = n - i; k > 0; k-- )
{
System.out.print( "* " );
}
System.out.println();
}
for (i = 0; i < n; i++ )
{
for (j = n - i; j > 1; j-- )
{
System.out.print( " " );
}
for (k = 0; k < i + 1; k++ )
{
System.out.print( "* " );
}
System.out.println();
}
Answer:
D. 4x as much
Explanation:
The answer is pretty simple. The question is asking about 10m/s and 20m/s right? Take a look at the energy at each point on the graph. At 10m/s the kinetic energy is 100 on the graph. At 20m/s the kinetic energy is 400. You'll notice that 100 x 4 is 400 - That's the answer.
You can also prove this mathematically. The formula for kinetic energy is
The question says: constant mass so we can ignore that for now.
(1/2) * 10^2 is (1/2) * 100 = 50
for the 20m/s ball it would be
(1/2) * 20^2 = 400 * 1/2 = 200
Once again, you see that it is 4x
