A 0.05kg ball falls a distance 20m after being dropped, calculate the work done in falling (show all working)
Answers
The work done in the fall of a 0.05 kg ball dropped from a height of 20 m is 9.8 Joules.
What is the work done in the fall of a 0.05 kg ball dropped from a height of 20 m?To calculate the work done in the ball's fall, we can use the formula:
Work = Force × Distance × cos(θ)
In this case, the force acting on the ball is its weight, which is given by:
Force = mass × acceleration due to gravity
Since the ball is falling freely, the acceleration due to gravity is approximately 9.8 m/s².
First, let's calculate the force:
Force = 0.05 kg × 9.8 m/s² = 0.49 N
Next, we can calculate the work done:
Work = 0.49 N × 20 m × cos(0°) = 9.8 J
Therefore, the work done in the ball's fall is 9.8 Joules.

Explain the comparative uses of the USDA Hardiness Zones and the Koppen-Geiger Scale.
Answers
The USDA Hardiness Zones are a system developed by the United States Department of Agriculture (USDA) to define climate zones based on the average annual minimum temperature. This system is primarily used to help gardeners and farmers determine which plants will grow best in a particular area. The zones range from 1 (coldest) to 13 (warmest), with each zone having a 10-degree Fahrenheit range of average annual minimum temperature.
On the other hand, the Koppen-Geiger Scale is a more comprehensive system that classifies climates based on several factors, including temperature, precipitation, and vegetation. This system is used by climatologists and geographers to study climate patterns on a global scale. The Koppen-Geiger Scale divides climates into five major groups: tropical, dry, temperate, continental, and polar. Each group is further divided into subcategories based on additional climate factors.
Overall, while both the USDA Hardiness Zones and the Koppen-Geiger Scale are used to categorize climates, they serve different purposes and have different levels of complexity. The USDA Hardiness Zones are mainly used for agricultural purposes and focus on temperature, while the Koppen-Geiger Scale is a more comprehensive system used by scientists to study climate patterns on a global scale.

Halim needs a newsletter for the youth group members. He wants you to create this month’s newsletter for him.
He has provided a file containing the text he wants in the newsletter. You need to prepare other information for the newsletter. You will do this in steps (a) and (b).
(a)
The members have been making weekly payments for a trip to Alton Towers. Halim has provided a file containing the trip payments data.
The trip cost is £28.25 per person. Halim needs to know the amount outstanding for each member. He also needs to know the total amount outstanding for all members.
(The amount outstanding for each member is the trip cost less the total of their weekly payments.)
Evidence you must upload
A file of the trip payments data including the values you calculated.
A file of how you used ICT to do your calculations (i.e. showing the formulas you used).
Answers
To calculate the amount outstanding for each member, you need to subtract the total of their weekly payments from the trip cost, which is £28.25 per person.
What is the newsletter about?For example, if a member has made weekly payments of £5, £7, and £9 respectively, the total of their weekly payments would be £21. To calculate the amount outstanding for this member, you would subtract £21 from £28.25, which gives you an amount outstanding of £7.25.
To calculate the total amount outstanding for all members, you need to sum up the amount outstanding for each member.
To do this, you can use a spreadsheet program like Microsoft Excel or Go/ogle Sheets. Create a table with the following columns: "Member Name," "Total Paid," "Amount Outstanding."

Let us recall that the total mechanical energy is constant and mechanical energy can be converted from kinetic energy to potential energy and vice versa.

Answers
The line that is drawn parallel to the given line is the green line shown in the image below.
Original slope = 1/2
Parallel slope = 1/2.
How to Find the Slope of a Line?The slope can be calculated as, m = change in y / change in x = rise / run.
The slope (m) of the given line = rise/run = 1/2
Parallel line have the same slope, therefore, the line that would be drawn parallel to the given line will have a slope, m = 1/2.
The equation of the original line is: y = 1/2x - 3. Thus, the line that is parallel to y = 1/2x - 3 that is displayed in the given graph will have an equation that has the same slope but different y-intercept, which can be: y = 1/2x + 2.

Answers
The complementary messenger-RNA sequence for the DNA sequence C-A-A-G-G-T is G-U-U-C-C-A.
This is because messenger-RNA is created by a process of transcription in which the complementary base is matched to each side of the DNA sequence.
In this case, the base C is matched with G, A is matched with U, and G is matched with C. Therefore, the complementary messenger-RNA sequence is G-U-U-C-C-A.
