Round the number 31.257592 to 5 significant figures.
Explanation:
Highlight the first 5 digits. You should highlight 3, 1, 2, 5, and 7 in that order.
Note the next digit after that is a 5, meaning we'll round that 7 up to 8
So 31.257592 becomes 31.258 when we round to five significant figures.

A 975 L balloon contains helium. On the ground the temperature is 30 0C and the pressure is 743 torr. What will be the balloon's volume at an altitude of 5700 m where the pressure is 375 mm Hg and the temperature is -35.0 0C?
Answer:
V₂ = 1518L
Explanation:
-Using combined gas law:
[tex]\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}[/tex]
Where P is pressure, V is volume and T is absolute temperature of 1, initial state and 2, final state of the gas.
Initial states:
P₁ = 743 torr
V₁ = 975L
T₁ = 30°C + 273.15K = 303.15K
P₂ = 375 mmHg = torr
V₂ = Our incognite
T₂ = -35°C + 273.15K = 238.15K
Replacing:
[tex]\frac{743torr*975L}{303.15K} =\frac{375torrV_2}{238.15K}[/tex]
V₂ = 1518La snail slowly moves along at 3 ft/hr. what type motion velocity ,distance, speed acceleration displacement Please answer need it now!!!!!

The density of mercury is 13.6 g/ml. What is the volume of 386g of mercury?
The density of mercury is 13.6g/lmL. The volume of a 200 gram sample of mercury will be :
Volume=
200g/13.6g/mL
Volume=14.7mL
Therefore the correct option will be E

A wave that travels at the speed of light and consists of a combined electric and magnetic effect
Answer:
Electromagnetic waves
Explanation:
The description given is that of an electromagnetic wave.
Electromagnetic waves are propagated by the vibration of electrical and magnetic fields in a perpendicular direction to one another.
These waves generally travel at the speed of light. They are made up of magnetic and electric fields. They do no require a material medium for their propagationThey can pass through a vacuum.When fossil fuels, such as gasoline, are burned, they create smoke. Smoke is best described as a heterogeneous mixture of solid particles from the burning fuel dispersed in a gas – usually air. Smoke can be described more specifically as a suspension. What will most likely happen over time to smoke in the atmosphere? The solid particles will spread out and dissolve. The particles will eventually come together in a cloud and produce rain. Over time, the solid particles will settle on whatever is outside. The particles will remain mixed in the air.
Answer:
Over time, the solid particles will settle on whatever is outside."

4. One of the most common predation relationships that can be seen in the Florida Everglades is between the Florida
Panther and the White Tailed Deer. Since the Florida Panther is an endangered species, what would happen to the
deer population as the panther population decreases in size?
A. The deer population would decrease.
B. The deer population would not be affected.
C. The deer population would increase indefinitely.
D. The deer population would increase and then level off.
Answer:
D
Explanation:
It would be D because it would increse yes in population because the panthers are decreasing and attacking less. But, it would still level off because there are other predators who can kill the white tailed deer. Also the panther who is endangered could still atack even though theres just a few left that does not affect them from attacking. So it would increase but it would still level off.
How did astronomers use technology to identify characteristics of the Crab nebula? technology that detects ultraviolet light found hydrogen in the nebula technology that detects radio waves identified a pulsar at the center of the nebula technology that detects microwaves revealed the behavior of electrons in the nebula technology that detects gamma rays measured the distance of the nebula from Earth
Answer:
technology that detects radio waves identified a pulsar at the center of the nebula
Explanation:
Crab nebula(M1) is a blob-like patch which is supernova remnants as far as Constellation of Taurus is concerned.
It has apparent magnitude of 8.4 and can only be viewed by telescope. The astronomers make use of technology that detects radio waves, which identified a pulsar at the center of the nebula, this pulsar is a magnetized rotating compact star which is known with it's electromagnetic emissions.
Answer:

A given mass of gas in a rigid container is heated from 100 °C to 300 °C. Which of the following best describes what will happen to the pressure of the gas? The pressure will
Taking into account the Gay-Lussac's Law, the pressure will increase by a factor less than three.
Gay-Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions against the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.
In summary, when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.
Mathematically, Gay-Lussac's law indicates that the ratio of pressure to temperature is constant:
[tex]\frac{P}{T} =k[/tex]
Studying two different states, an initial state 1 and a final state 2, it is satisfied:
[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]
In this case, a given mass of gas in a rigid container is heated from 100 ° C to 300 ° C, that is, it is heated from 373 ° K to 573 ° K. This indicates that the temperature is increasing by a factor less than three. Since pressure is directly proportional to temperature, pressure must increase in the same proportion.
Finally, the pressure will increase by a factor less than three.
