Momentum is the product of the mass and velocity of an object.
M = m x v
M = kg * m/s
Given:
Velocity = 40 km / hr
Mass = 480 kg
Conversion:
1km = 1000m
1hr = 3600s
40 km/ hr x 1000m/1km = 40000m/hr
40000m/hr x 1hr/3600s = 11.11m/s
Hence velocity is 11.11m/s
Solution:
1. M = m x v
2. M = 480 kg x 11.11m/s
3. M = 5332.8 Ns
Answer:
The rock cycle is driven by two forces: (1) Earth's internal heat engine, which moves material around in the core and the mantle and leads to slow but significant changes within the crust, and (2) the hydrological cycle, which is the movement of water, ice, and air at the surface, and is powered by the sun
Explanation:
Carbon, Oxygen, Hydrogen, and Nitrogen, all of these are found in DNA and RNA, Proteins, Lipids, and Carbohydrates.
Genetic variation is the variation in the DNA sequence in the genome of an organisms. Organisms of a species have similar characteristics but they are not identical due to genetic variation. Genetic variation is important in the survival and the adaptability of a given species of organism. Therefore, in this case lack of genetic variation necessary to adapt to change in the environment will lead to extinction of the fish species that lacks the variation.
