answer
v = 4.2
set up an equation
we can use the formula for kinetic energy since we know mass and kinetic energy
K =
v =
values
K = 0.013 J
m = 1.5g = 0.0015 kg
plug in values
v =
v = 4.2
thirty one and eight over se
venteen kilogram
Answer: A) 2 B) 4 C) 1
Explanation:
The Electric field from a parallel-plate capacitor is given by:
A) E=Q/(L^2 * ε0) so if we put a charge double the final electric field is double that the original.
B) from the above expression for the electric field, If the size of the plate is double, then the E final is four times weaker that the original.
C) If the distante between plates is doubled the final electric field is the same that initial.
Answer:
Period, T = 27.84 seconds
Explanation:
Given the following data;
Length of pendulum = 2m
We know that acceleration due to gravity on earth is equal to 9.8 m/s²
To find the period of oscillation of the simple pendulum;
Mathematically, it is given by the formula;
Substituting into the equation, we have;
Period, T = 27.84 seconds
Answer:
Gravity
