What two vertical forces act on a falling leaf?(1 point)

Physics
1 answer:
Sloan [31]2 years ago
5 0

Option C. Weight, Friction are the vertical forces that act on the leaf falling.

<h3>What are vertical forces?</h3>

These are forces that act in the vertical plane, which is perpendicular to the ground. There are at least two vertical forces acting. Gravitational force is provided by the earth and always acts downwards.

The weight, W (force) acting on the leaf is as a result of the product of the mass(m) of the leaf and the acceleration due to gravity (g).

Mathematically; W = mg

Friction in the form of air resistance also try to stop or reduce this acceleration due to gravity (g) on the falling leaf and it acts upwards.

In conclusion, Weight and Friction (air resistance) are the two vertical forces acting on a falling leaf.

To model time-variant data, one must create a new entity in an m:n relationship with the original entity.
Ksenya-84 [330]

To model time-variant data, one must create a new entity in an m:n relationship with the original entity, is a False statement.

  • Like the majority of software engineering initiatives, the ER process begins with gathering user requirements. What information must be retained, what questions must be answered, and what business rules must be implemented (For instance, if the manager column in the DEPARTMENT table is the only column, we have simply committed to having one manager for each department.)
  • The end result of the E-R modeling procedure is an E-R diagram that can be roughly mechanically transformed into a set of tables. Tables will represent both entities and relationships; entity tables frequently have a single primary key, but the primary key for relationship tables nearly invariably involves numerous characteristics.

A box is moving along the x-axis and its position varies in time according to the expression:
Colt1911 [192]

Answer:

38.4 m/s

Explanation:

a) at t = 3.2s. x = 6 * 3.2^2 = 61.44 m

b) at t = 3.2 + Δt. x = 6*(3.2 + \Delta t)^2

c) As Δt approaches 0. We can find the velocity by the ratio of Δx/Δt

v = \frac{\Delta x}{\Delta t} = \frac{x_2 - x_1}{\Delta t}

v = \frac{6*(3.2 + \Delta t)^2 - 61.44}{\Delta t}

v = \frac{6(3.2^2 + 6.4\Delta t + \Delta t^2) - 61.44}{\Delta t}

v = \frac{61.44 + 38.4\Delta t + \Delta t^2 - 61.44}{\Delta t}

v = \frac{\Delta t(38.4 + \Delta t)}{\Delta t}

v = 38.4 + \Delta t

As Δt approaches 0, v = 38.4 + 0 = 38.4 m/s
