Answer :
To determine which object has the greatest mass, let's look at the given masses, comparing them one-by-one:
- A grain of salt: [tex]\( 6.5 \times 10^{-2} \)[/tex] grams, which is equal to 0.065 grams.
- A grain of sand: [tex]\( 2.6 \times 10^{-3} \)[/tex] grams, which is 0.0026 grams.
- A dust particle: [tex]\( 7.0 \times 10^{-10} \)[/tex] grams, which is an incredibly small 0.0000000007 grams.
- A grain of rice: [tex]\( 2.8 \times 10^{-2} \)[/tex] grams, which is 0.028 grams.
Now, let's compare these values:
1. A grain of salt is 0.065 grams.
2. A grain of sand is 0.0026 grams.
3. A dust particle is 0.0000000007 grams.
4. A grain of rice is 0.028 grams.
Comparing all these values, 0.065 grams (for the grain of salt) is the largest mass among the four.
So, the grain of salt has the greatest mass.
- A grain of salt: [tex]\( 6.5 \times 10^{-2} \)[/tex] grams, which is equal to 0.065 grams.
- A grain of sand: [tex]\( 2.6 \times 10^{-3} \)[/tex] grams, which is 0.0026 grams.
- A dust particle: [tex]\( 7.0 \times 10^{-10} \)[/tex] grams, which is an incredibly small 0.0000000007 grams.
- A grain of rice: [tex]\( 2.8 \times 10^{-2} \)[/tex] grams, which is 0.028 grams.
Now, let's compare these values:
1. A grain of salt is 0.065 grams.
2. A grain of sand is 0.0026 grams.
3. A dust particle is 0.0000000007 grams.
4. A grain of rice is 0.028 grams.
Comparing all these values, 0.065 grams (for the grain of salt) is the largest mass among the four.
So, the grain of salt has the greatest mass.
