Answer:
D. Half as great
Explanation:
Since we know that the friction force between the surface of crate and ground is given as
so here we know that
= friction coefficient between two surfaces which depends on the effective contact area between two surfaces
= normal force due to the object
So when we turn the object on another side such that the surface area is half then the friction coefficient will become also half
So here the friction force will also reduce to half
so correct answer will be
D. Half as great
Density=mass/volume

Answer:
Product labels are important for explaining to consumers what they are buying. This can be a safety issue if customers have allergies or health concerns.
Explanation:
The equator is the closest part of out planet that is closest to the sun, which means that the continents closest to the equator will in turn be warmer.
Explanation:
Power is the product of current and voltage:
P = IV
And from Ohm's law, voltage is the product of current and resistance:
V = IR
So substituting this expression for V into the power equation:
P = I (IR)
P = I² R
