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

\frac{1}{2}mv^2

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

Allocate 100 integers and assign the resulting pointers to the elements of ip_arr. Initialize each integer value to -1.
dmitriy555 [2]

Answer:

#include <iostream>

using namespace std;

int main() {

   int *ip_arr,n;//pointer name inp_arr and integer n to store the size.

   cin>>n;//size.

   for(int  i=0;i<n;i++)

   ip_arr[i]=-1;//assigning -1 to every element.

  for(int i=0;i<n;i++)

  {

       cout<<ip_arr[i]<<" ";//printing every element.

  }

return 0;

}

output:-

100

-1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1  

Explanation:

I am taking input of size.You should enter 100 for 100 values which have value -1.
