When the core runs out of hydrogen to fuse, then it starts fusing the helium. This happens because a star cannot create more hydrogen.
Answer:
Product, 
P = 639619.091888
Explanation:
In this case, we need to find the product of two numbers. These are as follows :


On doing calculation, we get the product of two numbers as :


P = 639619.091888
In scientific notation the product of two number is given by :

Hence, this is the required solution.
Answer:
Heat is transferred from the fire through the wire by conduction.
Explanation:
Answer:
E=1824.81 V/m
Explanation:
Given that
Voltage difference = 5 V
Distance ,D= 3 mm
θ = 24°
As we know that electric filed given as

Given that D is 24° with respect to the perpendicular to the electrodes.So we have to take cos component of D.
d= D cosθ
d= 3 cos24°
d = 2.74 mm
So


E=1824.81 V/m
