**Answer:**

By applying a force of one Newton, one can hold a body of mass of **102 gram.**

**Explanation:**

- Force is the
**pull or push** of an object. It can be mathematically measured as, **F= m* g.**

where, F= force in newton

m= mass in kg

g= acceleration due to gravity ( )

F= m* 9.8

or, m= = 0.102 kg

or, **m= 102 gram. **

- Hence, 102 gram mass can be hold by one Newton force.

**Answer:**

it is good so far

i just passed my math test

**Explanation:**

Pulleys can be used to lift heavy objects that otherwise may not be able to be lifted. They reduce the amount of force it takes to lift a load.

**Answer:**

**Atomic radius decreases moving from left to right across a period.**

**Explanation:**

When we move left to right across a period, the size of atoms generally decreases. It is because within the period the outer electrons are in same valence shell and the number of electrons and proton increases moving from left to right across the the period. It** increases the effective nuclear charge** resulting in the increased attraction of electron to the nucleus that causes the decreased radius of the atoms.

**Answer:**

E. The ocean gains more entropy than the iron loses.

**Explanation:**

When there is a spontaneous process , entropy of the system increases . Here hot iron is losing entropy and ocean is gaining entropy . Net effect will be gain of entropy . That means entropy gained by ocean is more than entropy lost by iron .

Hence option E is correct .
