Answer:didn’t put the number for how many blue cups were used
Explanation:
Work is said to be done when an object moves due to a force applied. Work is calculated by multiplying the force applied and the distance traveled due to the force. It is expressed as:
W = Force x distance
W = 84 J = F (7.0 m)
F = 12 N
Hope this answers the question.
The answer is; Jane would be right.
The atom was discovered be more of empty space. The mass of an atom is mainly attributed to the mass of the nucleus which occupies a very small fraction of the size of the atom. The nucleus is Located in the center surrounded by orbiting electrons.
The Geiger–Marsden experiment, where alpha particles are accelerated onto a thin aluminum foil proved this theory by Ernest Rutherford. Some of the particles were deflected by the foil and this was attributed to the dense nucleus of the aluminum atoms in the foil. The other particles passed through because most of the atoms are made of empty space.
Answer: A. 1
Mangrove swamps are wetland ecosystem found in the coastal area. These are found in regions where water body and terrestrial land meets. These ecosystem are dominated by mangrove trees due to their ability to servive in harsh saline water conditions. The roots of mangrove trees exhibit salt filteration system. These trees are habitat of many bird and animal species. The roots of these trees provide shelter, to underwater aquatic plant and animal species such as algea, prawns, sponges and fishes. Mangroves trees and algea are primary producers of the food chain in mangrove ecosytem. Mangrove tree leaves are eaten up by herbivores insects and algal species are consumed by large number of sea animals. Hence, mangrove tree and algea will be on the 1 number of the food chain.
