What is a disadvantage associated with many renewable or alternative energy sources

1 answer:

5 0

Its pretty expensive and can't be replaced immediately and some source like nuclear energy produces nuclear waste which produce radioisotope that is harmful for all living beings

Assume the first dot for animal A represents t = 0. At which time does animal B overtake animal A?

Maslowich

The time in which the animal B overtake animal A according to the motion map is at 2 seconds.

<h3>What is a Motion map?</h3>

This is referred to as one-dimensional plots built off of a position line and depicts velocity and acceleration.

The time in which Animal B is ahead of animal A is at 2 seconds which therefore makes it the most appropriate choice.

Damm [24]

Answer:

Distance = 4.4 [m]

Explanation:

This problem can be easily solved using a static analysis of forces acting on the ladder, taking into account the respective distances. For easy understanding, a free body diagram should be made.

We perform a sum of force on the X-axis equal to zero, to find that the force exerted by the wall is equal to the friction force on the floor.

Then we perform a summation of forces on the Y axis, to determine that the normal force exerted by the floor is equal to the weight of the ladder.

We know that the friction force is equal to the product of normal force by the coefficient of friction.

In this way, by relating the friction force to the equations deduced above we can find the force exerted by the wall.

Then we make a summation of moments around the base point of the ladder, the equation realized can be seen in the attached image.

In the last analysis we can find the relationship between the horizontal and vertical distance of the ladder, with respect to the wall and the floor.

Then with the complementary analysis of the Pythagorean theorem we can find another additional equation.

The result of the greater distance is 4.4 [m]
