While pushing a wagon around the park steve applies a force of 100n along thd handlr which makes 32cangle with the ground if he pushes it 25 metree how much wrk dods he fo
Answer:
Workdone = 2120 Joules.
Explanation:
Given the following data;
Force applied = 100N
Angle = 32°
Distance = 25m
To find the workdone by Steve, we would first of all find the horizontal component of the force applied.
[tex] Horizontal force, Fx = mgCosd[/tex]
Where;
Fx represents the horizontal force.
m is the mass of an object.
g is the acceleration due to gravity.
d is the angle of inclination (theta).
mg = weight = 100N
Substituting into the equation, we have;
[tex] Fx = 100 * Cos32[/tex]
[tex] Fx = 100 * 0.8480[/tex]
Fx = 84.80N
Workdone is given by the formula;
[tex] Workdone = force * distance[/tex]
Substituting into the equation, we have;
[tex] Workdone = 84.80 * 25 [/tex]
Workdone = 2120 Joules.

How would you compare a circle to an ellipse?
Answer:
A circle is a closed curved shape that is flat. ... Instead of having all points the same distance from the center point, though, an ellipse is shaped so that when you add together the distances from two points inside the ellipse (called the foci) they always add up to the same number.

Place in order the correct sequence by which water flows through plants
1. transpiration from the leaves
2. absorption from the soil by root hairs
3. movement from roots to stem
4. flow upwards in the stem
Answer:
The correct sequence is - 2, 3, 4, 1.
Explanation:
The movement of the water takes place in the plant from the soil and moves up to leaves and from there to the atmosphere. Root hairs help in the absorption of the water from the soil with help of the epidermis of root hairs. Water then takes the path from the root to the stem with help of cortical cells.
Once the water reaches the endodermis or endodermal cell the water freely flow in the xylem cell upwards the stem moves to leaves by the transpiration stream. In the process of transpiration, an excess amount of water evaporates into the atmosphere.
each of these statements is a key characteristic of science, except: group of answer choices science focuses on explaining the natural world. science is based on the premise that things and events that happen in the natural world occur in consistent patterns that are comprehensible through careful systematic study. science is a process for producing knowledge which may be abandoned or modified in light of new evidence or reconceptualization of prior evidence and knowledge. scientists will never seek additional data once they confirm a hypothesis. both c and d.
Answer:
scientists will never seek additional data once they confirm a hypothesis
Explanation:
All the options are characteristics of science except the one that says that scientists will never seek additional data once they confirm a hypothesis.
That a hypothesis is confirmed does not mean that scientists are done and dusted with that phenomenon. One of the reasons the experiments that are used to test hypotheses are usually reproducible is to allow for continuous testing even after hypotheses have been confirmed. Continuous confirmation of hypotheses by many independent researchers turns the hypotheses into law and from there, theories can become laws when they are overwhemingly accepted worldwide and test against a wide range of phenomena.
Generally, science is a process of producing knowledge about the natural world. A previously held belief in science can be abandoned or modified once new evidence emerges

Two students were having a discussion about viruses.
Student A believes viruses are not living organisms .
Student B believes viruses are living organisms.
Which student is correct and why?
Student A is RIGHT because viruses are not living organisms.
All living organisms are composed of cells, and viruses do not have cells (they only have protein coats that protect their genetic material).Viruses are entities that need to parasite the cells of different host organisms to survive.In consequence, a virus cannot replicate in absence of a suitable host cell.In conclusion, student A is RIGHT because viruses are not living organisms.
