Answer:
1) Stirring and pulverizing the soil before seeds are planted or removed as well as to loosen the soil in order to allow enough air into the soil.
2) Vitamin A, zinc supplementation and exclusive breastfeeding
3)Manure from horses, cows or cattle
4) Mechanical
Explanation:
A cultivator is a farm implement used for stirring and pulverizing the soil before seeds are planted or removed as well as to loosen the soil in order to allow enough air into the soil. This enables the crop to grow quicker. It is driven by a tractor and does more work than the harrow which is not tractor driven.
Nutrition-specific intervention is a programme by UNICEF to talk undernutrition in foetus as well as growing children. The nutrients specified are exclusive breastfeeding, vitamin A and zinc supplementation.
Manure is referred to as major component used to aid crop growth. It contains essential nutrients which are required by crops for growth and good health. Manure is natural and can be gotten from animal dung.
Seed drills are sowing machines used to sow seeds accurately at the precise depth and distance measured. It does an extra work of covering the soil as well as protecting the seeds from birds. Due to the fact that it is a machine, it saves time and labour as well as money.
The earth got hit by a meteor billions of years ago and now it sits on an axis
Answer:
Both speed and mass causes the kinetic energy to change.
Explanation:
The energy an object because of its motion is called as Kinetic energy. A object that moves be it horizontal or vertical direction possess kinetic energy. Some forms of kinetic energy are rotational, vibrational, translational. The kinetic energy(K) of the object depends on two components i.e., the mass (m) of the object involved and its speed(v)
The relation between the mass, speed of the object can be represented as
![\text{Kinetic energy}=\frac{1}{2}$ mass $\times$velocity$^{2}$](https://tex.z-dn.net/?f=%5Ctext%7BKinetic%20energy%7D%3D%5Cfrac%7B1%7D%7B2%7D%24%20mass%20%24%5Ctimes%24velocity%24%5E%7B2%7D%24)
Kinetic energy$=\frac{1}{2} m \times v^{2}$
Thus when there is a increase in the mass and speed, the kinetic energy will also increase
