Given :

A 50 kg boy stands on rough horizontal ground. The coefficient of static friction, us, is 0.68.

To Find :

The maximum static friction between the boy and the ground is _ N.

Solution :

We know maximum static friction is given by :

$F = \mu mg \\\\F= 0.68\times 50\times 9.8\\\\F = 333.2\ N$

Therefore, maximum static friction is 333.2 N.

Hence, this is the required solution.

If the mass of a material is 45 grams and the volume of the material is 8 cm^3, what would the density of the material be?

Svet_ta [14]

The density of the substance is the ratio of its mass over the space it occupies. In mathematical equation, this can be expressed as,

ρ = m / v

where ρ is density, m is mass, and v is volume.

Substituting the known values from the given,

ρ = (45 g) / (8 cm³)

ρ = 5.625 g/cm³

<em>ANSWER: 5.625 g/cm³</em>

An object of mass m has these three forces acting on it (there is no normal force, "no surface"). F1 = 1 N, F2 = 9 N, and F3 = 5

hammer [34]

Answer:

solved

Explanation:

a) F_net = (F2 - F3)i - F1 j

b) |Fnet| = sqrt( (F2 - F3)^2 + F1^2)

= sqrt( (9- 5)^2 + 1^2)

= 4.123 N

c) θ = tan^-1( (Fnet_y/Fnet_x)

= tan^-1( -1/(9-5) )

= -14.036°

Fred wants to summarize mitosis in the cell cycle. Which statement describes mitosis?

salantis [7]

The statement that most accurately describes mitosis simply is <span>that mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself</span>. This is the most basic textbook definition, that is summary, of what the mitosis is.
