Answer:
2.3 ×
Explanation:
1 kg = 1000 g.
0.00023 kg x 1000 g = 0.23 grams
Answer:
10432.19076 m
Explanation:
= Wavelength = 660 nm
d = Diameter of pupils = 6 mm
s = Distance between lights = 1.4 m
L = Distance from observer
From Rayleigh's criteria we have
As is small
So, the equation becomes
The car is 10432.19076 m from me
Answer:
Explanation:
Given
Mass of object (m)=6 kg
falling height(h)=10 m
mass of water()=600 gm
temperature of water =15
specific heat of water
Let T be the Final Temperature of water
Here Object Potential Energy is converted into Heat energy which will be absorbed by water
Potential Energy(P.E.)
Heat supplied
T-16=0.234
This is not an efficient way of heating water as there is onlyincrease in temperature.
