Answer:
77.08 C
Explanation:
= mass of the water = 500 g = 0.5 kg
= specific heat of water = 4186 J/(kg °C)
= Rate of change of temperature = 3 °C /min = (3/60 ) °C /s = 0.05 °C /s
= thermal conductivity of glass = 0.84
= Area of the element = 0.090 m²
= thickness of the element = 1.5 mm = 0.0015 m
= Temperature inside = 75 °C
= Temperature outside = ?
Using conservation of energy
Heat gained by water = Heat transferred through glass
three charged particals are located at the corners of an equil triangle shown in the figure showing let (q 2.20 Uc) and L 0.650

Answer</h2>
The <u>inter or intramolecular bonding forces</u> affect the physical properties of the metals and nonmetals.
<h2>
Explanation</h2>
The bonding forces of the element in the periodic table get varied within the periods and groups. In the groups, more shells increase the shielding effects and in the periods, the repulsion among the electrons increases. These factors affect the behaviour of an atom during the process of making bonding or reactions. These are the reasons which make the most of the metals in the solid form and nonmetals in the liquid or gas forms.
Is there a list to chose from? but if theres not it would probably be some kind of plant
During the operation of fan we know that it is working on the electricity
So here when we connect the fan with electricity it uses the electrical energy and convert that energy into mechanical energy of fan
Fan uses this electrical energy to rotate the blades of fan and then it gives the high speed air to us
So here correct answer must be
B.
motion energy
