Questions

Kepler’s  laws  of  planetary  motion state  that  (a)  All  planets  move  in elliptical orbits with the Sun at one of  the  focal  points  (b)  The  radius vector  drawn  from  the  sun  to  a planet  sweeps  out  equal  areas  in equal  time  intervals.  This  follows from  the  fact  that  the  force  of gravitation on the planet is central and  hence  angular  momentum  is conserved.  (c)  The  square  of  the orbital   period   of   a   planet   is proportional  to  the  cube  of  the semi  major  axis  of  the  elliptical orbit of the plane.

T = 273 °K

Using the formula,

DGq = DHq –TDS

-45 = -90 –273 DS

DS = 0.164

Now since DHq and DSq are independent,T2= DH/DS = 45/0.164 = 273°K

Required Temp = 273 + 273 = 546°K

Water possess intermolecular hydrogen bonding in the condensed phase.

Hence, the given statement 'There is extensive intramolecular hydrogen bonding in the condensed phase.' about water is FALSE.

 #include<stdio.h>
int main(){
  int r,i,j,k;
  printf("Enter the number range: ");
  scanf("%d",&r);
  for(i=1;i<=r;i++){
      for(j=1;j<=10;j++)
           printf("%d*%d=%d ",i,j,i*j);
      printf("\n");
  }
  return 0;
}

Sample Output:
Enter the number range: 5

Lewis Hamilton of Mercedes won the Hungarian Grand Prix for the 6th time, at the Hungaroring circuit, in Hungary.

This is the 67th career victory for Lewis Hamilton.

Aldosterone is a steroid hormone that is produced in the adrenal gland. It is useful and more essential for the conservation of sodium content in the kidney, salivary glands, colon and sweat glands.

Here, Aldosterone increases sodium reabsorption by increasing the number of Na+-K+ ATPase pumps in the luminal membrane of the proximal tubule is the only option that is NOT correct about aldosterone.

One turn of the citric acid cycle produces

1. Two molecules of carbon dioxide are released.

2. One molecule of ATP or GTP is produced.

3. Tree molecules of NADH and one molecule of FADH2 are generated.
