Answer:

a = 1.25m/s^2

Explanation:

Force = mass x acceleration

Given mass M = 48kg and

Force F = 60N

60 = 48 x a

Divide both sides by 48

60/48 = 48 x a/48

1.25 = a

a = 1.25m/s^2

A package of aluminum foil contains 50. Ft2 of foil, which weighs approximately 7.0 oz . Aluminum has a density of 2.70 g/cm3. W

kumpel [21]

We know density = Mass / Volume

So Volume = Mass/Density

Volume = Area * Thickness

$Area = 50 ft^2 = 4.645152 m^2\\ \\Mass = 7 oz = 0.198447 kg\\ \\Density = 2.70 g/cm^3 = 2700 kg/m^3\\ \\Substituting \\ \\4.645152 *t = \frac{0.198447}{2700} \\ \\t = 1.58*10^{-5}m = 1.58*10^{-2}mm$

So the approximate thickness of the foil in millimeters = $1.58*10^{-2}mm$

Arrange the values according to magnitude

Talja [164]

Answer:

$59000$

$1.8\times 10^5$

$4.3\times 10^{-2}$

$9.0\times 10^{-6}$

$8.4\times 10^{-6}$

Explanation:

The given numbers are

$1.8\times 10^5=18000$

$4.3\times 10^{-2}=0.043$

$8.4\times 10^{-6}=0.0000084
$

$9.0\times 10^{-6}=0.000009$

$59000$

The arrangement of the numbers from largest to smallest is

$59000$

$1.8\times 10^5$

$4.3\times 10^{-2}$

$9.0\times 10^{-6}$

$8.4\times 10^{-6}$ .

A bag of sugar weighs 3.50 lb on Earth. What would it weigh in newtons on the Moon, where the free-fall acceleration isone-sixth

Alex73 [517]

Answer:

$F_{Earth}$ = 15.57 N

$F_{Moon}$ = 2.60 N

$F_{Uranus}$ = 16.98 N

The mass of the bag is the same on the three planets. m=1.59 kg

Explanation:

The weight of the sugar bag on Earth is:

g=9.81 m/s²

m=3.50 lb=1.59 kg

$F_{Earth}$ =m·g=1.59 kg×9.81 m/s²= 15.57 N

The weight of the sugar bag on the Moon is:

g=9.81 m/s²÷6= 1.635 m/s²

$F_{Moon}$ =m·g=1.59 kg× 1.635 m/s²= 2.60 N

The weight of the sugar bag on the Uranus is:

g=9.81 m/s²×1.09=10.69 m/s²

$F_{Uranus}$ =m·g=1.59 kg×10.69 m/s²= 16.98 N

The mass of the bag is the same on the three planets. m=1.59 kg

A motorcycle is capable of accelerating at 5.1 m/s starting feom rest how far can it travel im 1.5 seconds

saul85 [17]

5.1 m/ s

~Multiply 1.5 on both sides since you’re trying to finding out how far it can travel in 1.5 seconds

5.1 x 1.5= 7.65

s x 1.5= 1.5

So a motorcycle can travel 7.65 m in 1.5 seconds.
