The new pressure P2 is 2.48 atmosphere.
<u>Explanation:</u>
Here, the one of the product of pressure and volume is equal to the products of pressure and volume of other.
By using Boyles's law,
pressure is inversely proportional to volume,
P1 V1 = P2 V2
where P1, V1 represents the first pressure and volume,
P2, V2 represents the second pressure and volume
P2 = (P1 V1) / V2
= (1.75
8.8) / 6.2
P2 = 2.48 atmosphere.
Answer: #.37 times greater
Explanation: Volume of a sphere is: V =
·π·r³
Since it is given the diameter of the basketball and the softball, their ratios are r₁ = 3in and r₂ = 2in, in which index 1 represents the basketball and index 2, the softball.
Calculating the volume of basketball:
V₁ =
. 3.14 . 3³
V₁ = 113.04 in³
Calculating the volume of softball:
V₂ =
. 3.14 . 2³
V₂ = 33.5 in³
Comparing one volume with the other:
=
= 3.37
We have that V₁ = 3.37V₂
This means the volume of a basketball is 3.37 times greater than the volume of a softball.

Answer:
A
Explanation: This is the correct answer
Answer:
0.0002 C.
Explanation:
Charge: This can be defined as the ratio of current to time flowing in a circuit. The S.I unit of charge is Coulombs (C)
Mathematically, charge can be expressed as
Q = CV ................................. Equation 1
Where Q = amount of charge, C = capacitance of the capacitor, V = potential difference across the plates.
Given: C = 2.0-μF = 2×10⁻⁶ F, V = 100 V.
Substitute into equation 1
Q = 2×10⁻⁶× 100
Q = 2×10⁻⁴ C
Q = 0.0002 C.
The amount of charge accumulated = 0.0002 C
