The advantage of using a solar cooker is that it is Eco-friendly and the disadvantage is that it can be used only under certain conditions.
<h3><u>
Explanation:</u></h3>
A solar cooker is used for cooking food without having to use electricity or gas. Instead, the appliance uses heat from the sun to cook food. It is used widely in by people who travel in remote areas or go on trips. But the appliance has limitations of its own too.
ADVANTAGES
- Using it is friendly to the environment
- It can be easily assembled without expert assistance
- No compromise on the quality and taste of foo
DISADVANTAGES
- Requires sun to function and prepare food
- Cannot function in winters or monsoon when the sun isn't present
- Does not retain heat as efficiently and quickly as compared to other cooking appliances
Answer:
<h2>E) 52.5 cm</h2>
Explanation:
Step one:
given data
period T= 3 milliseconds= 0.003
velocity v= 175m/s
wave lenght λ=?
Step two:
we know that f=1/T
the expression relating period and wave lenght is
v=λ/T
λ=v*T
λ=175*0.002
λ=0.525m
to cm= 0.525*100
=52.5cm
The wavelength of the wave is E) 52.5 cm
Answer:
The current on the water layer = 1.64×10^-3A
Explanation:
Let's assume that the radius given for the string originates from the centre of the string. The equation for determining the current in the water layer is given by:
I = V × pi[(Rwater + Rstring)^2 - (Rstring)^2/ ( Resitivity × L)
I =[ 166×10^6 ×3.142[(0.519×10^-4) + (2.15×10^-3])^2 - ( 2.15×10^-3)^2] / ( 183 × 831)
I =[ 521572000(4.848×10^6)- 4.623×10^-6]/ 154566
I = 252.83 -(4.623×10^-6)/ 154566
I = 252.83/154566
I = 1.64× 10^-3A
