Answer:

181.89 N

Explanation:

The force necessary to start the create moving = frictional force.

F = μR................... Equation 1

Where F = Force necessary to start the create moving, μ = coefficient of static friction. R = normal reaction.

But,

R = mg ........................ Equation 2

Where m = mass of the crate, g = acceleration due to gravity of the plate.

Substitute equation 2 into equation 1

F = μmg...................... Equation 3

Given: m = 32 kg, μ = 0.58, g = 9.8 m/s²

Substitute into equation 3

F = 32(9.8)(0.58)

F = 181.89 N

What is the scientific method
Alex_Xolod [135]
The scientific method is an empirical tool that can be used to study phenomenon by asking questions, conducting experiments, and making observations to prove or disprove hypotheses. The scientific method has been used as a baseline tool in hard and social sciences to conduct experiments and to make conclusions about phenomenon in our natural world.

small plastic container, called the coolant reservoir, catches the radiator fluid that overflowswhen the automobile engine becom
Ilia_Sergeevich [38]

Answer:

0.53 quart

Explanation:

The volume expansion of the coolant is gotten from ΔV = VγΔθ where ΔV   = change in volume of the coolant, V = initial volume of coolant = 15 quart, γ = coefficient of volume expansion of coolant = 410 × 10⁻⁶ /°C and Δθ = temperature change = θ₂ - θ₁ where θ₁ = initial temperature of coolant = 6 °C and θ₂ = final temperature of coolant = 92 °C. So, Δθ = θ₂ - θ₁ = 92 °C - 6 °C = 86 °C

Since, ΔV = VγΔθ

substituting the values of the variables into the equation, we have

ΔV = VγΔθ

ΔV = 15 × 410 × 10⁻⁶ /°C × 86 °C

ΔV = 528900 × 10⁻⁶ quart

ΔV = 0.528900 quart

ΔV ≅ 0.53 quart

Since the change in volume of the coolant equals the spill over volume, thus the overflow from the radiator will spill into the reservoir when the coolant reaches its operating temperature of 92 °C is 0.53 quart.
