A strand of hair has an average mass of 2.17×10^−5 ounces. A grain of rice has an average mass of 0.002 ounces. How much heavier is a grain of rice than a strand of hair? Express your answer in scientific notation.(1 point)
To find how much heavier a grain of rice is than a strand of hair, we need to subtract the mass of a strand of hair from the mass of a grain of rice.
The mass of a grain of rice is given as 0.002 ounces, and the mass of a strand of hair is given as 2.17×10^−5 ounces.
Subtracting these two values gives:
0.002 - 2.17×10^−5 = 0.0019983 ounces
To express this answer in scientific notation, we can write it as:
1.9983×10^−3 ounces
To find the difference in weight between a grain of rice and a strand of hair, we subtract the mass of the hair from the mass of the rice:
Mass of rice - Mass of hair
Given:
Mass of hair = 2.17×10^−5 ounces
Mass of rice = 0.002 ounces
So the difference in weight can be calculated as:
0.002 ounces - 2.17×10^−5 ounces
To subtract the two values, we need to convert 2.17×10^−5 ounces to the same unit as 0.002 ounces.
Converting 2.17×10^−5 ounces to standard decimal notation:
2.17×10^−5 = 0.0000217
Now, we can subtract the two values:
0.002 ounces - 0.0000217 ounces = 0.0019783 ounces
The result in scientific notation is:
1.9783×10^−3 ounces
To calculate how much heavier a grain of rice is than a strand of hair, we need to subtract the mass of the hair from the mass of the rice.
The average mass of a strand of hair is given as 2.17×10^−5 ounces.
The average mass of a grain of rice is given as 0.002 ounces.
To determine the difference, we subtract the mass of the hair from the mass of the rice:
0.002 ounces - 2.17×10^−5 ounces
To subtract these values, we need to convert the hair mass to the same order of magnitude as the rice.
2.17×10^−5 ounces can be written as 0.0000217 ounces in standard notation.
Now we can perform the subtraction:
0.002 ounces - 0.0000217 ounces
This gives us the result of 0.0019783 ounces.
To express the answer in scientific notation, we need to move the decimal point to the proper location and adjust the exponent:
0.0019783 ounces can be written as 1.9783×10^−3 ounces.
Therefore, a grain of rice is approximately 1.9783×10^−3 ounces heavier than a strand of hair.
is this correct?
Apologies for the error in the previous response. Let's correct the calculation:
To find the difference in weight between a grain of rice and a strand of hair, we subtract the mass of the hair from the mass of the rice.
Given:
Mass of hair = 2.17×10^−5 ounces
Mass of rice = 0.002 ounces
So the difference in weight can be calculated as:
0.002 ounces - 2.17×10^−5 ounces
To subtract these values, we need to convert 2.17×10^−5 ounces to the same unit as 0.002 ounces.
Converting 2.17×10^−5 ounces to standard decimal notation, we have:
2.17×10^−5 = 0.0000217
Now, we can subtract the two values:
0.002 ounces - 0.0000217 ounces = 0.0019783 ounces
To express the answer in scientific notation, we need to move the decimal point to the proper location and adjust the exponent:
0.0019783 ounces can be written as 1.9783×10^−3 ounces.
Therefore, a grain of rice is approximately 1.9783×10^−3 ounces heavier than a strand of hair.
Apologies for any confusion caused by my previous incorrect response.
