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

Physics
1 answer:
Sloan [31]1 year 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.

An engine absorbs 1.69 kJ from a hot reservoir at 277°C and expels 1.25 kJ to a cold reservoir at 27°C in each cycle.
Anna35 [415]

Answer

Given,

Energy absorbed, Q_H = 1.69\ kJ

Energy expels,Q_C =  1.25\ kJ

Temperature of cold reservoir, T = 27°C

a) Efficiency of engine

 \eta = \dfrac{Q_H - Q_C}{Q_H}\times 100

 \eta = \dfrac{1.69 - 1.25}{1.69}\times 100

\eta =26.03 %

b) Work done by the engine

 W = Q_H- Q_C

 W =1.69 - 1.25

 W = 0.44\ kJ

c) Power output

     t = 0.296 s

   P = \dfrac{W}{t}

   P = \dfrac{0.44}{0.296}

   P = 1.486\ kW

galben [10]

What Newton discovered is that  gravity extends throughout the universe.

<h3>What is gravity?</h3>

The term gravity refers to the force that acts on a body in the universe. It is gravity that makes an object to fall when it is thrown up. The force of gravity acts on every object in the universe and it extends through the universe.

Humans have always known about gravity when they fall from a height and when they threw things up. However, human did not know that gravity extends throughout the universe.

Thus, what Newton discovered is that  gravity extends throughout the universe.
