The big bang theory refers to a theoretical concept that explains the creation of our universe. It postulates that the universe started with a giant explosion that created all matter and propelled it outwards in all directions. It is the existence of cosmic background radiation that supports the big bang theory within cosmology.
Answer:
4 P
Explanation:
V = IR
when they are in series R = 2 r
when they are in parallel R = 1/2 r
so current will increase by a factor of 4 when they are in parallel
and power used will also increase by a factor of 4 to 4 P
Power = IV when I now becomes 4 I power becomes 4 P
Answer:
mass = 0.44 Kg
Explanation:
given,
Calories contain in the strawberry yogurt = 255 calories
1 Calorie = 4186 J
latent heat of vaporization = 2.42 x 10⁶ J/Kg
mass of perspiration = ?
Energy = 255 calories
Energy = 255 x 4186
= 1067430 J
Energy = mass x latent heat of vaporization
mass = 0.44 Kg
Answer: 3.21 N
For weight, we will multiply by 
Hence, the rock would weigh 3.21 N.
It is considered a substance because it has a uniform and definite composition.
