Answer:c-The gravitational effect when spacecraft flies close to the asteriod

Explanation:

Gravitational effect on the spacecraft gives an estimate that how big is the asteroid by experiencing its gravitational pull.

The amount of extra thrust required to maintain the trajectory of the spacecraft during its motion hints at the scientist about the size of the asteroid.

Gravitational pull is directly proportional to the mass of object so greater the mass, greater will be the pull.

Answer:

decreasing the surface area.

Explanation:

The rate of reaction or the reaction rate may be defined as the speed or the rate at which the reaction occurs. It is the speed of formation of the products from the reactants. The following factors increases the rate of reaction :

1. by adding a catalyst

2. by increasing the temperature

3. by increasing the pressure

4. by increasing the surface area

5. by increasing concentration

Hence, decreasing the surface area of the reaction reduces the rate of reaction.

To solve this problem it is necessary to apply the concepts related to the conservation of energy and heat transferred in a body.

By definition we know that the heat lost must be equal to the heat gained, ie
