Answer:
1.Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.
2.The acceleration of the bus that decreases its speed from 80 kilometers per hour to 60 km per hour in 5 seconds is -1.12m/s.
3.The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.
4. The things we get from cereals, pulses, fruits and vegetables are as follows: Cereals (wheat, rice, maize, etc.): are the sources of carbohydrates which provide energy. Pulses (pea, gram and soybean, etc.): are source of proteins. Vegetables and fruits: provide us vitamins, minerals, carbohydrates, proteins and fats.
5.Manures and fertilizers are used in fields to supply plant nutrients to the soil which increases soil fertility in order to ensure good vegetative growth that results in high crop production. it helps in enriching the soil with nutrients, organic matter and increasing soil fertility.

Answer:
How is this social science -_-
Explanation:
1. Speed -(a) Its a scalar quantity
(b)Has only magnitude .
Velocity -(a) Its a vector quantity
(b)Has both magnitude and direction
2. a = 60-80/5
= -20/5
= -4km/h^2
3. IDK
4. Vitamins and Minerals
5. To supply nutrients to soil and maintain its soil fertility .
