Answer:
the blue shopping cart.
Explanation:
The blue shopping cart doesnt have to worry about running someone over in the front. The red one does, so it slows down more.
Answer:

Explanation:
Since the cardinal and ball have the same kinetic energy, it is possible to determine the ratio between speeds. (c for cardinal, b for baseball)



The ratio is obtained by multiplying each side by
:


The value of this ratio is:

The number of protons an element has is its atomic number so the atomic number would be 29
First, we need to know the amounts of the elements in the compound.
Tin (Sn)= 5.28 g
Fluorine (F) = 8.65 - 5.28 = 3.37 g
Convert these to units of moles by dividing the molar masses.
Tin (Sn)= 5.28 g / 118.71 g/mol = 0.044 mol
Fluorine (F) = 3.37 g / 19.00 g/mol = 0.177 mol
Divide both by the least number of moles of the two.
Tin (Sn)= 0.044 mol / 0.044 mol = 1
Fluorine (F) = 0.177 mol / 0.044 mol = 4
Therefore, the empirical formula would be:
SnF4
Answer:
its a negative work, not a negative force
Explanation:
I took the quiz first i put negative force i got it wrong
then when i put negative work it was right
Hope it help:)♥︎ plz mark me as brainliest
