R 1,2 = 27.5 + 33.0 = 60.5 Ohms
1/ R 1,2,3 = 1/ 60.5 + 1 / 22 = 82.5 / 1331
R 1, 2, 3 = 1331 / 82.5 = 16.13 Ohms
I = U / R
I = 9 V / 16.13 Ohms = 0.557 A ≈ 0.56 A
Answer: C ) 0.56 Amps

Ostrovityanka [3204]
The force can be determined using the equation F (force) = mass * acceleration. The unit of measurement, N (Newton), is equivalent to kilogram-meter/seconds2.
Thus, F= 1300 kg * 1.07 m/s2 = 1391 N.
The resultant value is 1391 N.

Approximately 1.000 g each of four gasses H2, Ne, Ar, and Kr are placed in a sealed container all under1.5 atm of pressure. Assu
serg [3582]

Answer:

The partial pressure of H2 is 0.375 atm.

The partial pressure of Ne also stands at 0.375 atm.

Explanation:

Mass of H2 = 1 g

Mass of Ne = 1 g

Mass of Ar = 1 g

Mass of Kr = 1 g

Overall mass of the gas mixture totals 4 g.

Pressure in the sealed container is 1.5 atm.

Calculating the partial pressure for H2 yields: (mass of H2/total mass of gas mixture) × pressure of sealed container = 1/4 × 1.5 = 0.375 atm.

Calculating the partial pressure for Ne similarly gives: (mass of Ne/total mass of gas mixture) × pressure of sealed container = 1/4 × 1.5 = 0.375 atm.

The gas tank of Dave’s car has a capacity of 12 gallons. The tank was 38 full before Dave filled it to capacity. It cost him $2.
Sav [3153]

Answer:

$ 18.75

Explanation:

Given:

Dave's car has a capacity of 12 gallons.

If the tank is at 3/8 full prior to filling:

The cost of gasoline per gallon is $2.50.

The volume Dave needs to fill:

=1 - \dfrac{3}{8}

=\dfrac{5}{8} of full tank

=\dfrac{5}{8}\times 12

Dave must fill 7.5 gallons.

Total amount Dave will pay:

7.5 gallons x $2.50 =

$ 18.75

Thus, Dave will spend $ 18.75 to completely fill the tank.

A man is dragging a trunk up the loading ramp of a mover’s truck. The ramp has a slope angle of 20.0°, and the man pulls upward
Sav [3153]

Response:

(a) 104 N

(b) 52 N

Clarification:

Provided Information

Incline angle of the ramp: 20°

F forms a 30° angle with the ramp

The parallel component of F along the ramp is Fx = 90 N.

The perpendicular component of F is Fy.

(a)

Consider the +x direction pointing up the slope, and the +y direction perpendicular to the ramp's surface.

Using the Pythagorean theorem, decompose F into its x-component:

Fx=Fcos30°

To find F:

F= Fx/cos30°

Insert the value for Fx based on the given info:

Fx=90 N/cos30°

   =104 N

(b) Calculate the y-component of r using the Pythagorean theorem:

     Fy = Fsin 30°

Substituting for F from part (a):

     Fy = (104 N) (sin 30°)  

          = 52 N
