Use what you know about mass and how you use it to calculate force in the following situation. If each washer has a mass of 4.9 g, then the mass of two washers in kilograms would be . Given that F = ma, and if 4 washers are attached to the string and car instead of 2, then the applied force on the car will be .

If each washer has a mass of 4.9 g, then the mass of two washers in kilograms would be

✔ 0.0098 kg

.

Given that F = ma, and if 4 washers are attached to the string and car instead of 2, then the applied force on the car will be  

✔ 0.196 N

. Recall a = 10 m/s2

Explanation:

for the first blank:

✔ 0.0098 kg

for the second blank:

✔ 0.196 N

Explanation:

I can confirm those answers are correct because I just took the test and got them both right.

powerful computers now, not then

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
