Answer:
2C
Explanation:
The equivalent capacitance of a parallel combination of capacitors is the sum of their capacitance.
So, if the capacitance of each capacitor is half the previous one, we have a geometric series with first term = C and rate = 0.5.
Using the formula for the sum of the infinite terms of a geometric series, we have:
Sum = First term / (1 - rate)
Sum = C / (1 - 0.5)
Sum = C / 0.5 = 2C
So the equivalent capacitance of this parallel connection is 2C.
The shell's horizontal position and vertical position are given by
where is the given speed of 1.70 x 10^4 m/s, and is the acceleration due to gravity (taken here to be 9.80 m/s^2).
To find the horizontal range, you can use the range formula,
with being the angle at which the shell is fired.
Alternatively, we can work backwards and deal with part (b) first:
(b) The time spent in the air is the time it takes for the shell to reach the ground. To find that, you solve for in :
(a) After this time, the shell will have traveled horizontally
The answer is C. ionic compounds, compared to another hard compound which is the covalent bond, the structure of the ionic compound is lattice or crystalline in form thus less room for imperfections on its structure compared to the latter choices.
Answer:
The contraction in the rod is 71 mm.
Explanation:
Given that,
original length L'= 2.99 m
Speed
We need to calculate the length
Using expression for length contraction
Where,
Where, v = speed of observer
c = speed of the light
Put the value into the formula
The expression for the contraction in the rod
Hence, The contraction in the rod is 71 mm.
