Explanation:
Given data the power input to the refrigerator is 450 W
The COP of refrigerator is 1.5
Temperature 

mass of watermelon =10 kg
specific heat =4.2 KJ/kg°C
The amount of heat removed from 5 watermelon

We know that 

W=0.675 KW
so time required to cool the watermelon is
Answer:
A) 209.12 GPa
B) 105.41 GPa
Explanation:
We are given;
Modulus of elasticity of the metal; E_m = 67 GPa
Modulus of elasticity of the oxide; E_f = 390 GPa
Composition of oxide particles; V_f = 44% = 0.44
A) Formula for upper bound modulus of elasticity is given as;
E = E_m(1 - V_f) + (E_f × V_f)
Plugging in the relevant values gives;
E = (67(1 - 0.44)) + (390 × 0.44)
E = 209.12 GPa
B) Formula for upper bound modulus of elasticity is given as;
E = 1/[(V_f/E_f) + (1 - V_f)/E_m]
Plugging in the relevant values;
E = 1/((0.44/390) + ((1 - 0.44)/67))
E = 105.41 GPa
Answer:
f(5)
Explanation:
Function notation is a precise way of giving information about a function without need for a lengthy written explanation. The most common function notation is f (x) which is interpreted as "f of x".
For the year 2005,
t = 2005 -2000
= 5
Using the function notation to represent the cost (in dollars) of a new Accord in 2005 is f(5)
Answer:
A Bipolar Junction Transistor, or BJT, is a solid-state device in which the current flow between two terminals (the collector and the emitter) is controlled by the amount of current that flows through a third terminal (the base).
The main basic function of a BJT is to amplify current it will allow BJTs are used as amplifiers or switches to produce wide applicability in electronic equipment include mobile phones, industrial control, television, and radio transmitters. There are two different types of BJTs are available, they are NPN and PNP.
