Answer:

The resistance interval is $R = 1.8 \pm 0.037$

Explanation:

From the question we are told that

The voltage is V = 9 V

The current is $I = 5 \pm 0.1$

The maximum current would be

$I_{max} = 5 + 0.1 = 5.1 \ A$

The minimum current would be

$I_{min} = 5 - 0.1 = 4.9 \ A$

The maximum resistance is

$R_max = \frac{V}{I_{min}}$

$R_max = \frac{9}{4.9}$

$R_max = 1.837 \Omega$

The minimum resistance is

$R_{min} = \frac{V}{I_{max}}$

$R_{min} = \frac{9}{5.1}$

$R_{min} = 1.765 \Omega$

and $R = \frac{9}{5} = 1.8 \Omega$

The interval R lies is

$R = 1.8 \pm 0.037$

Does an Atom of different elements have different number of protons

Murrr4er [49]

Atoms from two different elements may have the same number of neutrons, but never the same number of protons. The number of protons is unique to the element and represents the atomic number.

Which type of stress is responsible for squeezing rock? shear compressional gravitational tensional

kykrilka [37]

The answer is Compressional.

Compression is a stress that pushes and squeezes rocks together. This causes the rock to bend or fracture.

Tension is a stress that pulls rocks apart. Shear stress occurs when the rocks are moving parallel but opposite of each other pushing rocks at different directions. Gravitational stress is stress induced by gravity.
