Answer: when heated and for answer dont forget to hit the brainliest
Explanation:
Answer:
8 atm
Explanation:
Ideal gas law:
PV = nRT
where P is pressure, V is volume, n is moles, R is universal gas constant, and T is absolute temperature.
If n is constant:
PV / T = PV / T
(4 atm) (60 L) / (27 + 273) K = P (40 L) / (127 + 273) K
0.8 atm = 0.1 P
P = 8 atm
Increasing the mass of an object increases its momentum.
Explanation:
- Momentum of an object is measured as the quantity of motion done by the object.
- It is calculated using the formula, p = m × v where m is mass of the object and v is the velocity of the object.
- As momentum and mass vary proportionally, as seen in the formula, increasing the mass of an object will also increase its momentum.
Answer:
Analog,Noise,Digital,less
Explanation:
Analog signal changes continuously with time and moves smoothly.
Due to this analog signal can easily disturbed by noise.
Since digital signal are like square wave due to this digital signals are less affected by noise.
Because the Analog signal changes smoothly, like a sine wave, it can closely mimic a human voice. However, part of the signal can easily get lost to Noise. Because Digital signals are on or off, like a square wave, they best carry information that can easily be converted into numbers. These signals are less affected by noise.
<span>example shows that electromagnetic waves can travel without moving through a specific material is
</span>light passing through a vacuum tube
because it shows that there is no medium
so correct option from above is D
hope it helps
