a. reflect (I found this using prior knowledge and process of illumination it can't be absorb cuz you wouldn't see anything it can't be refract because it doesn't reverse the image and it isn't transmit )

Answer:
12.5J
Explanation:
Given parameters:
Mass of bucket = 1.7kg
Height = 75cm = 0.75m
Unknown;
Work done on the bucket by the person = ?
Solution:
To solve this problem, we use the work done equation;
Work done = force x distance = mgh
m is the mass
g is the acceleration due to gravity
h is the height
Now, insert parameters and solve ;
Work done = 1.7 x 9.8 x 0.75 = 12.5J
It means you can do 550 Newton Meters of work every second. Power is the rate of doing work, I hope this helps
Animal testing is unreliable because the results may not be precise to what it might do to humans because our bodies do not work the same.
it is cruel to the animals that are being forced to be test subject because they are forced to put their life in the line and they don’t have any say in it because they don’t speak English. (More than 100 million animals die a year while testing products)
This is affecting the earth because the animals are given severe abdominal pain, diarrhea, seizures, and many more awful side effects. The chemicals given to animals include pesticides, dyes, cosmetics and many other harmful things
