Following directions in an experiment is crucial for accurately studying the effect of a variable, obtaining valid and repeatable results, and ensuring safety. It is integral to the scientific method, which involves making observations, forming a hypothesis, conducting an experiment, and analyzing results.
It's critical to follow all directions in an experiment correctly for several causes. First, experiments are a part of the scientific method, a process for investigating phenomena and acquiring new knowledge, or correcting and integrating existing knowledge. This method includes making observations, forming a hypothesis, conducting an experiment to test the hypothesis, and analyzing the results to reach a conclusion.
Second, correctly implementing the experimental procedure is necessary to measure the effect accurately and eliminate any lurking variables. It also involves control and experimental groups, which need to be treated differently only in the variable that's being tested. This way, any difference in results is attributed to that variable. Repeating the process under the same conditions confirms that your results were not accidental.
Finally, not following directions can lead to invalid results, incorrect conclusions, and even potential risks and hazards, particularly in certain fields such as chemistry or medicine. Therefore, meticulousness in adhering to instructions is essential for the reliability and safety of the experiment.

If Linh removes bulb 3,the bulbs which will remain lit are 1, 2 and 4.
The electric circuit provided with battery creating potential difference across resistance or capacitor or inductors.
When Linh removes the middle branch, the bulbs 1, 2 and 4 will be acting as resistor which are in series connection. The current flow will be same in all the resistors except 3.
Thus, If Linh removes bulb 3, the bulbs which will remain lit are 1, 2 and 4.

Explanation:
Just took the quiz :)
hydrogen atoms.
Explanation:
This is because unsaturated fatty acids have at least two double-bonded carbon atoms, so they cannot bond with the maximum number of hydrogen atoms.
Answer:
hydrogen atom
Explanation:
they have at least two double bonded carbon atoms,so they they can't bond with the maximum number of hydrogen atom

The ball's initial speed is calculated using the principles of projectile motion. First, the time it takes for the ball to hit the ground is found using the vertical distance and acceleration due to gravity. the initial speed to be approximately 7.9 m/s.
The problem describes a case of projectile motion, a common topic in physics. Since the ball is thrown horizontally, the initial vertical velocity of the ball is zero. We're given that the horizontal distance covered is 24.0 m and the vertical distance is 45.0 m.
Because the horizontal and vertical motions are independent, we can use the equations of motion to solve the problem. First, we have to find the time it takes for the ball to hit the ground. Using the equation of motion
"y = 0.5*g*t²",
where y = 45 m is the vertical distance, g = 9.8 m/s² is the acceleration due to gravity, and t is the time in seconds. Solving for t gives us the square root of (2*y/g), which is approximately 3.03 seconds.
Second, we use this time to find the initial speed of the ball. The horizontal distance covered x = 24.0 m is equal to the product of the time it's been travelling and its initial horizontal speed (v = x/t). Using the time from the previous step, we can find the initial speed to be approximately 7.9 m/s.
