Neither are Strong acid.

<h3>What does “strong acid” mean?</h3>

In the solution, solid acids entirely separate into ions. For instance, hydrochloric acid is a solid acid.

It totally ionizes, forming hydrogen and chloride ions. Nitric acid and sulfuric acid are also components of strong acids.

A solid or strong acid is one that has completely dissociated into ions. It is a weak acid if it does not dissociate completely.

<h3>What is an example of a strong acid?</h3>

Chloric acid, hydrobromic acid, hydrochloric acid, hydroiodic acid, nitric acid, perchloric acid, and sulfuric acid are the seven major acids that make up strong acids. These are referred to as strong acids since they can totally dissociate in water.

The resistance and the magnitude of the current depend on the path that the current takes. The drawing shows three situations in

mihalych1998 [28]

Answer:

a) Ra = 0.517 Ω

Rb = 0.032 Ω

Rc = 0.129 Ω

b) Ia = 5.8A

Ib = 93.75A

Ic = 23.2 A

Explanation:

a) The resistance is equal to:

Resistance for case a:

$R_{a} =\frac{pL_{a} }{A_{a} } =\frac{p*4*L_{0} }{2L_{0}*L_{0} } =\frac{2p}{L_{0} }$

Where

p = 1.5x10⁻²Ωm

L0 = 5.8 cm = 0.058 m

$R_{a} =\frac{2*1.5x10^{-2} }{0.058} =0.517ohm$

Resistance for case b:

$R_{b} =\frac{pL_{b} }{A_{b} } =\frac{pL_{0}}{2L_{0}4L_{0} } =\frac{p}{8L_{0}} =\frac{1.5x10^{-2} }{8*0.058} =0.032ohm$

Resistance for case c:

$R_{c} =\frac{pL_{c}}{A_{c} } =\frac{p2L_{0}}{L_{0}4L_{0}} =\frac{p}{2L_{0}} =\frac{1.5x10^{-2} }{2*0.058} =0.129ohm$

b) The current is equal to:

Current for case a:

$I_{a} =\frac{V}{R_{a} } =\frac{3}{0.517} =5.8A$

Current for case b:

$I_{b} =\frac{V}{R_{b} } =\frac{3}{0.032} =93.75A$

Current for case c:

$I_{c} =\frac{V}{R_{c} } =\frac{3}{0.129} =23.2A$

4. An object moves in a circular path at a constant speed. Compare the direction of the object’s velocity and acceleration vecto

Vikentia [17]

Answer:

Option C

The vectors are perpendicular

Explanation:

Acceleration will be directed towards the center for uniform circular motion. Consequently, velocity of the object increases hence acceleration. The direction of velocity is tangent to its circular motion, therefore, tangential velocity vector is perpendicular to centripetal acceleration vector. Therefore, comparing the direction of the object, the vectors are perpendicular to each other.

lisov135 [29]

Cosmology physics is used to describe the interaction of matter and energy from the beginning of the cosmic singularity to the Planck time.

Astronomy's field of cosmology examines the beginnings and development of the universe, from the Big Bang through the present and into the future. The current cosmology model for the development of the universe is the Big Bang theory, which relies on the validity of general relativity. There is a singularity there as well.

According to the Big Bang theory, the cosmos was once compressed into an infinitely small point 13.77 billion years ago. Prior to $10^{-43}$ seconds after the Big Bang, during the Planck Era, gravity, nuclear strong, nuclear weak, and electromagnetic forces are thought to have been merged into a single "super" force.
