Answer:
The correct answer is:
It asks about a cause-and-effect relationship between two variables (A)
Explanation:
Scientific investigations are aimed as developing a hypothesis and proving the validity or not of the hypothesis developed. In order for these hypotheses to be tested, experiments must be done, and the experiments are designed based on the identification of a cause-and-effect relationship existing between two variables to be tested, where the "cause" is varied to various degrees and the "effect" of the variation is recorded. Therefore, knowing the cause-and-effect relationship will guide the experimental design, which will be aimed at manipulating the causes to see how these manipulations affect the second variable.
Answer:
h = 200 m
Explanation:
The energy content of the chocolate is completely converted to the potential energy of the climber. Therefore:
where,
m = mass of climber = 50 kg
Energy of Chocolate = 100 KJ = 100000 J
g = acceleration due to gravity = 10 m/s²
h = height = ?
Therefore,
<u>h = 200 m</u>
Answer:
c. Synaptic transmission
Explanation:
To transmit impulses/electronic signals around the body, nerve cells transfer messages across the synapse and the movement of the chemicals from one cell to the other is known as either diffusion or synaptic transmission.
The correct answer is
(1) a 15-kg mass traveling at 5.0 m/s
<span>In fact, the inertia of an object depends only on its mass. The inertia gives a measure of "how hard is to put an object in motion", or "how hard is to stop an object in motion": the greater the mass, the larger the inertia of the object. In this problem, we have 4 objects, and the object with greatest mass is the first one (15 kg), therefore this is also the object with greatest inertia.</span>
Answer:
Explanation:
the lowest points of a transverse wave are called the troughs what is the wavelength of a wave traveling through a rope if the distance from one crest to the next is 1 meter a. 2 m
