If a load of 600 N is overcome by a simple machine using an effort of 400 N. Calculate the mechanical advantage.​

Answers

Answer:

‎ㅤ➙ Mechanical Advantage= 1.5

Solution:

Mechanical advantage allow to perform tasks much easier in terms of the force needed to apply, but must always obey the conservation of energy. Mechanical advantage is the measure of the ratio of output force to input force needed in a system, used to analysis the force in simple machines like livers and pulleys.

Mechanical advantage is given by:

[tex] \qquad\hookrightarrow\quad {\pmb{\sf{MA =\dfrac{Load}{effort} }} }[/tex]

We are provided with:

Load = 600 NEffort = 400 N

Therefore,

[tex] :\implies\quad \sf{MA = \dfrac{L}{E} }[/tex]

[tex] :\implies\quad \sf{ MA = \dfrac{6\cancel{00}}{4\cancel{00}}}[/tex]

[tex] :\implies\quad \sf{MA=\dfrac{6}{4} }[/tex]

[tex]: \implies\quad \sf{ MA =\dfrac{3}{2}}[/tex]

[tex]: \implies\quad\underline{\underline{\pmb{ \sf{ MA = 1.5}}}}[/tex]

‎ㅤ‎ㅤ‎ ‎ㅤ‎ㅤ‎~Hence, the mechanical advantage is 1.5

Question :-

If a Load of 600 N is overcome by a Simple Machine using an Effort of 400 N . Calculate the Mechanical Advantage .

Answer :-

Mechanical Advantage is 1.5 .

[tex] \rule {180pt} {2pt} [/tex]

Given :-

Load = 600 NEffort = 400 N

To Find :-

Mechanical Advantage = ?

Solution :-

As per the provided information in the given question, the Load is given 600 N . Effort is given as 400 N . And, we have been asked to calculate the Mechanical Advantage .

For calculating the Mechanical Advantage , we will use the Formula :-

[tex] \bigstar \: \: \boxed{ \sf{ \: Mechanical \: Advantage \: = \: \dfrac{Load}{Effort} \: }} [/tex]

Therefore , by Substituting the given values in the above Formula :-

[tex] \dag \: \: \sf{Mechanical \: Advantage \: = \: \dfrac{Load}{Effort} } \\ [/tex]

[tex] \longmapsto \: \: \sf{Mechanical \: Advantage \: = \: \dfrac{600}{400} } \\ [/tex]

[tex] \longmapsto \: \: \sf{Mechanical \: Advantage \: = \: \dfrac{6}{4} } \\ [/tex]

[tex] \longmapsto \: \: \sf{Mechanical \: Advantage \: = \: \dfrac{3}{2} } \\ [/tex]

[tex] \longmapsto \:\textbf{ \textsf{Mechanical Advantage = 1.5}} \\ [/tex]

Hence :-

Mechanical Advantage = 1.5 .

[tex] \underline {\rule {180pt} {4pt}} [/tex]

Answers

The store associated with the energy when a ball has 10 J of energy when it is 1 m above the floor is gravitational potential energy

What is gravitational potential energy?

Gravitational potential energy is the energy of a body by virtue of its position in the gravitational field.

From the question, If a tennis ball has 10 J of energy when it is 1 m above the floor, first, a work of 10 J was done against gravity to lift the tennis from the floor to a height of 1 m. At the height of 1 m, the work of 10 J is converted to the gravitational potential energy of the tennis ball which is stored in the ball.

Hence, The energy associated when a tennis ball has 10 J of energy and it is 1 m above the floor is gravitational potential energy.

How is thermal equilibrium reached? Question 3 options: When both objects have the same temperature When objects have the same mass When objects are both in the same state of matter (solid, liquid, or gas) When objects have different temperatures.

Answers

In the thermal equilibrium, the change in temperature is said to be zero in between the bodies. Thermal equilibrium is reached when both objects have the same temperature.

What is thermal equilibrium?

Thermal equilibrium is easily explained by the zeroth law of thermodynamics. If any two-body is at thermal equilibrium there is no change in the temperature of the body.

According to zeroth law if body A is in thermal equilibrium with body B and body B is in thermal equilibrium with C . So body A and C are also in thermal equilibrium.

In the thermal equilibrium, the net heat transfer is said to be zero in between the bodies.

Answers

Answer:

In short, a force applied to an object at rest causes it to accelerate in the direction of the force.

Explanation:

Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e. to change its velocity, at a constant rate.

Answer:

As the force acting upon an object is increased, the acceleration of the object is increased.

Explanation:

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.
