Work done = 100J
Distance = 5 meters
Force = ?

Force = 100/5 = 20N
Therefore, the force needed is 20 Newtons
One type of landform formed by wind would be sanddunes. This is the only landform I can think of formed by wind. The wind blows the sand along so that it builds up into a dune perhaps when it hits an obstacle like a small rocky spur and whole deserts can be converted into dunes.
Answer:
a) The question "Do pumpkins grow bigger when fed milk?" it is already a hypothesis, which means that to apply the scientific method, we should establish an experiment, where we would select a squash squash, feed some with milk and some without milk and wait a certain period of time. After that time, we could move on to the stage of the scientific method called "evaluation of results" where we would evaluate the differences in development and size between the pumpkins that were fed with milk and those that were not. After that we would go to the phase called "conclusion" where based on the comparison of the results we would answer the hypothesis shown above.
b) A scientific question could be "Can bean seeds germinate in sterile soil?"
Explanation:
Scientific method is a set of steps that must be followed when someone wants to prove a hypothesis based on experimental and scientific data. These steps are: visualization of something questionable, formulation of the hypothesis about it, establishment of a scientific experiment to test the hypothesis, evaluation of the results of the experiment and conclusion.
A scientific question is every question that you can perform a scientific experiment to answer it. This scientific experiment is carried out with the steps of the scientific method.
The plant species that live in the colder environment have some adaptations that makes them survive in that conditions
These plants have a well developed vascular system due to which they have the ability to trap every inch of sunlight available for the process of photosynthesis.
Some of the plants shed their leaves and stay in dormant conditions.
Evergreen trees have thick waxy coating that prevents the loss of water.
The plants that grow in arctic regions are small and they grow close to the ground in a specific shape that helps them to shed snow from them.
