I think b, if the spaceship is outerspace lol.
The cost of using 14,400 watts hour would be $43.2.
<h3>What is Energy ?</h3>
Energy is defined as the capacity to do work.
It is given in the question that
A 1600 watts electric oven is used for 9 hours
Power * Time
power = 1600 watts
Time = 9 hours
Total energy consumed = 1600 watts * 9 hours
= 14,400 watts hour
energy is measured in Kilowatts hour
= 14,440 watts hour
14,440/1000 kwh
= 14.4 kwh
It is given that the cost per unit of energy is $3.00 per kwh
Therefore , the cost of using 14,400 watts hour would be 14.4 * 3
= $43.2
The function of Voltmeter and Ammeter is to measure Voltage and Current respectively.

Answer:
Explanation is given below.
Explanation:
The cold pack is applied on the injured part of body only the place where the type of injury is Sprain, swelling, or any other internal small injury. This is applied to lower the flow of blood in that particular area which reduces the further inflammation of that area.
For the applied pack the direction of the flow of the heat will be towards the cold pack which will absorb the heat of the injured part as the heat always flows from higher temperature to the lower temperature.
This method of treatment of an injury is the instant way of treating an injury which prevents further problem to the injury by reducing the blood flow to the site and cooling the affected area.
In some kind of a 0.800 m ba(oh)2 solution, each individual ion has a concentration of 1.81M.
<h3>What are the 5 most common electrolytes?</h3>
Together with magnesium, calcite, phosphate, and bicarbonates, salt, potassium, & chloride are the important electrolytes. We obtain electrolytes from our diet and drinks. Unbalanced amounts of these electrolytes might result in either low or high levels.
<h3>Briefing:</h3>
In a solution of Ba(OH)2 at a concentration of 0750 M, Ba2+ is the predominant ion. = 0.800M and OH⁻ = 1.50 M.
The dissociation equation is:
Ba(OH)²(s)=Ba²+aq+2OH-aq
Using the Ba(OH)2 mole ratio: Ba₂⁺which is 1: 1 the concentration of Ba² is = 0.750M
By utilising Ba(OH)2's mole ratio: which is 1:2 the concentration of
OH=0.800*2/1
=1.81M
Individual ion concentration is therefore ba(oh)2 = 0.800M & = 1.81M.

Answer:
The primary type of energy change which occurs by turning on the phone will be the conversion of the stored chemical energy of the battery into electrical energy. The chemical energy is also converted into light energy, sound energy and heat energy. With the passage of time, the energy will be changed back into the chemical energy when we will charge the phone again.
