Answer:

Figure 1: Downward arrow

Figure 2: Downward arrow

Figure 3: Upward arrow on the rod.

Explanation:

The initial force which is applied for a machine to begin work is known as an input force. Machines are designed such that input force increases so that output force increases. Mechanical advantage determines the quality of machine. It is the ratio of output force to the input force.

<u>In figure 1, input force is applied in downward direction so the lever lifts up the barrel at the other end. </u>

<u>In figure 2, input force is applied downwards so that rope is pulled down and at the other end, the load is lifted upwards. </u>

<u>In figure 3, Input force lifts is applied in upward direction to lift the rod which drives the wheel. </u>

What is the best inference for the speed of the car after 3 seconds
SVEN [57.7K]

Answer:

B. 17m/s

Explanation:

This question contains a graph that illustrates the relationship between the speed of a car over time. The graph shows that one can make an inference of the amount of time it takes for the car to cover a particular speed and vice versa.

In this case, after 3 seconds, the speed of the car will be 17 m/s. This inference was got by tracing the position of 3s in the x-axis to the value on the y-axis. Doing this, the best inference for the speed of the car after 3 seconds is 17m/s.

A neutral atom as the same number of protons and electrons.
ZanzabumX [31]

That is correct. Or so I believe. Either more or less than the other on the amount of protons and electrons, you can get either an unstable or a stable atom of an element.

In a controlled experiment why is it important to change just one variable parameter at a time
kiruha [24]
Think of it this way: If you test only one variable then you know that the difference in the experimental and control setup is that one independent variable. If you test more than one you will not know which one made the difference. Hope this helps :)
