Answer:

Explanation:
We are given that
Potential difference=V=154 V
Surface charge density=
Using 
We know that


Where

Using the formula


Using 
Hence, the spacing between the plates=
Answer:
Option B is the correct answer.
Explanation:
Thermal expansion

L = 1.2 meter
ΔT = 65 - 15 = 50°C
Thermal Expansion Coefficient for aluminum, α = 24 x 10⁻⁶/°C
We have change in length

New length = 1.2 + 1.44 x 10⁻³ = 1.2014 m
Option B is the correct answer.
D = (1/2)·at²
where d is the distance fallen, a is the acceleration (g in this problem), and t is the time
d = (1/2)·(9.8 m/s²)·(30 s)² = (1/2)·(9.8)·(900) m
d = 4410 m
The answer is b) 4410 m
Note: the mass of the raindrop is irrelevant since the acceleration due to gravity is independent of mass. (Galileo's Leaning Tower of Pisa experiment)
Answer: 0.192 N/m
Explanation:
Well, generally when a Hooke's Law experiment is performed the plot is in fact Force vs Displacement, being the Force (in units of Newtons) in the Y-axis and the Displacement (in units of meters) in the X-axis.
In addition, if we add a linear fit the resultant equation will be the Line equation of the form:

Where
is the slope and
is the point where the line intersects the Y-axis.
So, if the equation is:

The slope of this line is
which is also the spring constant
