Let h = depth of the rectangular tank.
Its volume is
V = (0.450 m)*(0.900 m)*(h m)
= 0.405h m³
The density of gasoline is about 0.77 kg/L = 719.7 kg/m³.
Because the mass of gasoline is given as 36.0 kg, its volume is
V = (36.0 kg)/(719.7 kg/m³)
= 0.05 m³
Therefore,
0.405h = 0.05
h = 0.1235 m
The capacity of the tank in gallons is
(36 kg)/(0.77 kg/L) = 46.75 L
Because 1 L = 0.264 gal, the capacity is
(46.75 L)/(1/0.264 L/gal) = 177.1 gal.
A typical passenger can hold between 12 and 17 gallons, so this tank is too large.
Answer:
The depth is 0.1235 m.
The volume is 0.05 m³.
The tank is too large for a passenger car.
Answer:
The mass is inversely proportional to the acceleration so the acceleration a1 is twice that acceleration a2
Explanation:
The force of friction and the kinetic force make the law of mass in moving so
The forces are the same however at the moment to determinate the acceleration
are constant because they make the same motion however the difference of mass make the acceleration difference
Answer:
58,800 Joules
Explanation:
I used the formula for Potential energy which is PE = mgh
200 kg x 9.8 m/s^2 x 30 m = 58,800 J
At the very tops of the rollercoaster is maximum PE which is 58,800 J and 0 J of KE, but at the very bottom is maximum KE (kinetic energy) which is 58,800 Joules but 0 J of PE. This is because energy can not be destroyed ONLY converted
Answer: An ideal ammeter would have zero resistance, because to ensure that, there is no voltage drop due to the internal resistance. Similarly, an ideal voltmeter would have infinite resistance, because to ensure that there is no current is drawn by the voltmeter.
Explanation: To find the answer, we need to know about the Ammeter and Voltmeter.
<h3>What is an ammeter?</h3>
- An ammeter is a device, that can be used to measure the electric current flows through a circuit in amperes.
- An ideal ammeter would have zero resistance, because to ensure that, there is no voltage drop due to the internal resistance when it is connected in series to measure the current.
<h3>What is voltmeter?</h3>
- A voltmeter is a device, that can be used to measure the electric potential difference generated between the terminals of an electric circuit in volts.
- An ideal voltmeter would have infinite resistance, because to ensure that there is no current is drawn by the voltmeter, when it is connected in parallel to measure the voltage.
Thus, we can conclude that, an ideal ammeter would have zero resistance, because to ensure that, there is no voltage drop due to the internal resistance. Similarly, an ideal voltmeter would have infinite resistance, because to ensure that there is no current is drawn by the voltmeter.

Answer:
Explanation:
The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place.
The transfer of oxygen into the blood is through simple diffusion.The oxygen molecules move, by diffusion, out of the capillaries and into the body cells.
