<u>Answer</u>

= 100 miles per hour.

<u>Explanation</u>

Velocity is the rate of change of displacement.

Velocity = Distance /time taken

              = 500/5

              = 100 mile per hour.

A resistor is connected to a 36v power supply. An ammeter measures a current of 2.0 A going through it. Determine the resistance
m_a_m_a [10]

R = 18 ohms

Explanation:

Given:

V = 36 volts

I = 2.0 A

R = ?

Use Ohm's law to solve for the resistance:

V = IR

or

R = V/I

= (36 volts)/(2.0 A)

= 18 ohms

Describes the first law of thermodynamics
Sergio039 [100]

Answer:

Thermodynamics is usually defined as a branch of physics that deals with the study of the heat and various form of energy, and their interaction between the.

The first law says that heat appears as energy, and it cannot be produced and also cannot be demolished. It can only change from one form to another. This signifies that the total amount of energy present in the universe remains constant.

This first law can be mathematically represented as:

ΔU = Q - W

where ΔU = Changes occurring in the internal energy

              Q = amount of heat added to the system

              W = Amount of work done by the system

Calculate the ph of the solution that results following addition of 24 ml of 1.0 mnaoh to 60 ml of 1.0 mnh4cl.
Lostsunrise [7]

The pH of the solution is 0.37.

<h3>What is the pH of the solution?</h3>

We can write the equation of the reaction as;

NH4Cl (aq) + NaOH (aq) ------- > NH3 (aq) + H2O (l) + NaCl (aq)

Number of moles of NaOH= 24/1000 * 1 = 0.024 moles

Number of moles of NH4Cl= 60/1000 * 1  = 0.060 moles

Given that the reaction is 1:1, the limiting reactant is NaOH

Number of moles of NH4Cl left over = 0.060 - 0.024 = 0.036 moles

Concentration of left  over NH4Cl = 0.036 moles/(24 + 60)/1000

= 0.43 moles

pH = -log(0.43)

pH = 0.37

if u connect 3 resistors, having values 2ohm, 3ohm, 5ohm in parallel, will the value of total resistance of will be 2ohm or grea
Tju [1.3M]
<span>If u want only WHether the total resistance is less than 2 or less than 5 or more than 5 ohms:  there is a Simple way.

When you connect resistances in parallel, resultant resistance is always smaller than all of them. So it is less than 2 ohms</span>.

What is the definition of elastic limit in hookes law?
notsponge [240]
Within the elastic limit of a solid material, the deformation (strain) produced by a force (stress) of any kind is proportional to the force. If the elastic limit is not exceeded, the material returns to it original shape and size after the force is removed, other it remains deformed or stretched.
