Protons are positively charged and neutrons are neutral whereas electrons are negatively charged.
Answer:
0.69
Explanation:
Sum of the forces on the sled in the y direction:
∑F = ma
Fn - 52 N = 0
Fn = 52 N
Sum of the forces on the sled in the x direction:
∑F = ma
36 N - Fn μ = 0
Fn μ = 36 N
μ = 36 N / Fn
Substitute:
μ = 36 N / 52 N
μ = 0.69
<span>Density is a value for
mass, such as kg, divided by a value for volume, such as m3. Density is a
physical property of a substance that represents the mass of that substance per
unit volume. To find the mass of the substance, we need to multiply the volume occupied by the substance.
Mass = Density x Volume
Mass = 7.9 g/cm^3 (5.5 cm)^3
Mass = 43.45 g </span>
