Answer:
Yes
Explanation:
I've done plenty of research by hitting myself repeatedly. It does hurt after awhile.
To that multiply 1.9 by 5 to get 9.5. The zebra has gone 9.5 m.
Answer:
380000 km
Explanation:
The number is 380000
From the right
The first digit is the ones place
The second digit is the tens place
The third digit is the hundreds place
The fourth digit is the thousands place
The fifth digit is the ten thousands place
The sixth digit is the hundred thousands place
While reading a number we read the first digit on the left and add which place it is at.
Then the next digit as well as the place it is at.
Here the 3 is at the hundred thousands place. So, we say three hundred.
Then we read the next digit which is 8 and is at the ten thousands place.
So, we say three hundred and eighty thousand
Answer:
X ray
Explanation:
To see an object the light used must have the same or smaller wavelength than the object. The size of an atom is about
m, smaller than the wavelength, therefore we'll need radiation with a shorter wavelength <em>since X-ray wavelengths are about the same size as atoms this characteristic makes it ideal to use.</em>

The total heat that is needed by the water to get converted to steam is calculated below through the equation,
H = (Hv)(n)
where H is the heat, Hv is the heat of vaporization (40.67 kJ/mol), and n is the number of mols. Substituting the known values,
H = (40.66 kJ/mol)(1.5 mol) = 60.99 kJ
Calculating for the time,
t = (60990 J) / (24 J/s)
t = 2541.25 s
Answer: 2541.25 s or approximately 42.35 minutes
