Answer:
Option (D)
Explanation:
n = 0.35,
Temperature of hot reservoir,
T1 = 427 C = 700 K
Temperature of cold reservoir, T2 = ?
Use the formula for efficiency of Carnot cycle
n = 1 - T2 / T1
0.35 = 1 - T2 / 700
0.65 = T2 / 700
T2 = 700 × 0.65
T2 = 455 K
Answer:
Explanation:
From the given information:
We know that the thin spherical shell is on a uniform surface which implies that both the inside and outside the charge of the sphere are equal, Then
The volume charge distribution relates to the radial direction at r = R
∴
To find the constant k, we examine the total charge Q which is:
∴
Thus;
Hence, from equation (1), if k =
To verify the units:
↓ ↓ ↓
c/m³ c/m³ × 1/m
Thus, the units are verified.
The integrated charge Q
since
Hypothesis: The water will squirt far.
Indep.V.: Height of hole.
Depend.V.: Range of squirt
Constant: Everything that isnt the independant var. such as filled liquid.
Control: None,I believe.
Number of groups: 4
Trials per group: 4
