The smallest division on the scale of the triple beam balance is .1 g. What is the error in mass for measurements made with this
1 answer:
Starting from the definition of a triple beam scale, we could say that this is a measuring instrument whose name comes from its operating system. It is made up of three beams which each carries different weights: One is responsible for measuring what corresponds to increments of 100g, the other to the range of increments of 10g and the third to a single range of 0 to 10g. The error for a triple beam measurement system can be twice the tenth of the minimum count, therefore
If we took this example into practice if we had a mass of 54.38343g
The error would be:

Answer:
Explanation:
The force that one atom exerts on the other is the negative derivative of the potential energy =
F(x) = - ( -C₆ / x⁷) = - (- (-6) C₆ x⁻⁶ ⁻¹) = - 6C₆ /x⁷
when xis negative, F is positive and when x is positive, F is negative. It is therefore and attractive force and F is always directed to the center
Answer:
A. 181.24 N
Explanation:
The magnitude of hte electrostatic force between two charged objects is given by the equation
where
k is the Coulomb's constant
q1, q2 are the magnitudes of the two charges
r is the separation between the charges
In this problem, we have:
is the magnitude of the 1st charge
is the magnitude of the 2nd charge
r = 2.5 cm = 0.025 m is the separation between the charges
Therefore, the magnitude of the electric force is:
So, the closest answer is
A) 181.24 N
