2.If a sledgehammer that weighs 18 newtons on Earth will weigh about 4 newtons on the planet Namar, then your weight on Namar would be about ___ times your weight on Earth.
A. 0.25
B. 4
C. 0.5
D. Not enough information
0.25
Assume you weigh 100.
4/18 = x/100
400 = 18x
x = 22.22
Is that close enough to 0.25?
Four newtons is a bit less than one fourth of 18 newtons. (418 is nearly equal to 14.) This means that the weight of any object on Namar is about one fourth its weight on Earth. One fourth is the same as one divided by four, which is equal to 0.25.
To find out how many times your weight on Earth would be on the planet Namar, we need to calculate the ratio of the weight on Namar to the weight on Earth.
The weight of an object can be calculated using the formula:
Weight = mass × gravity
Where mass is measured in kilograms, and gravity is measured in newtons per kilogram (N/kg). On Earth, the gravity is approximately 9.8 N/kg.
Let's assume that your mass remains the same on both Earth and Namar. So, your weight on Earth would be 18 newtons.
We can use the same formula to calculate the weight on Namar using the given information that the sledgehammer weighs 4 newtons on Namar:
Weight on Namar = mass × gravity on Namar
Since the weight on Namar is 4 newtons and the weight on Earth is 18 newtons, we can set up the following equation:
4 = mass × gravity on Namar
We can solve for the gravity on Namar:
gravity on Namar = 4 ÷ mass
Now, let's substitute the gravity on Namar into the weight formula for Namar:
Weight on Namar = mass × (4 ÷ mass)
The mass cancels out, leaving us with:
Weight on Namar = 4
Therefore, your weight on Namar would be 4 times your weight on Earth.
So, the answer is B. 4
im so confused
what is 0.5 or 0.25?????
