Answer 1

Answer:

Answer:

Applied Research: It is a research conducted to find solutions for specific problems in a particular field of studies. Example, health effects on food that are genetically modified.

Basic research: It is basic research on any field to have a clear understanding of something from the existing knowledge. Example, the study on evolution of the living organisms.

Control: To increase the reliability of the result the scientific experiments decrease the number of variables (depending factors) in the experiment.

Dependent variable: This is a variable that determines the outcome of the result of an experiment depending on the independent variables. For example, stress influence the heart rate. Heart rate is a dependent variable.

Empirical evidence: It is the collection of scientific facts directly or indirectly. These facts support the scientific nature of the research. For example, measuring temperature, water freezing at a particular temperature and pressure.

Hypothesis: It is an explanation or assumption of a phenomenon based on limited empirical evidence. This is the first step of the research.

Independent variable: This is a variable that the experimenter has control to change. For example, stress influence the heart rate. Stress is an independent variable.

Which factor MOST directly affects the flow of ocean currents?A)
differences in pressure
B)
differences in temperature
C)
Earth's revolution round the Sun
D)
the Moon's revolution round Earth

Answers

Answer:

Correct Answer is B (Differences in temperature)

Explanation:

One of the main cause of ocean current to occur is variation of temperature of different layer of oceanic water.Water which have high temprature is less dense and this Less density water float above the surface of high density water. When this less density water reached on the surface of ocean that time wind which blows on the surface water makes the water cool or in other words we can say that water released its heat to the surrounding environment. when water becomes cool it again shifted in downward direction and less density water will moves upward. In this way this process will continue and hence ocean current is created.

A toy car runs off the edge of a table that is 1.225m high .the car lands 0.400m from the base of the table .

Answers

Answer:

a) 0.5s

b) 2.45m/s

Explanation:

The toy car in figure 6-12 runs off the edge of a table that is 1.225m high. The car lands 0.400m from the base of a table.

a) How long did it take the car to fall?

b) How fast was the car going on the table?

don't now if this helps but let me now if it did

Final answer:

The question is about a physics concept called projectile motion. First, we calculate the time the toy car is in the air using the height of the table and gravity, and then we find the horizontal velocity of the car as it leaves the table.

Explanation:

The question is about a situation where a toy car runs off the edge of a table and lands on the floor. This situation is a classic problem in physics pertaining to projectile motion or the motion of an object thrown in the atmosphere. Here, the motion is two-dimensional, including both vertical (free fall) and horizontal (uniform) motion.

First, calculate how much time the car is in the air using the height of the table and the acceleration due to gravity (approx. 9.81 m/s²). Using the free fall equation, t = √(2h/g), where h is the height of the table and g is the gravity, we get t = √(2*1.225m/9.81 m/s²) = 0.5 seconds. This is the time it takes for the car to hit the floor.

Next, we find the horizontal velocity using the formula s = d/t, where s is speed, d is distance and t is time. So, s = 0.400m/0.5s = 0.8 m/s. This is the speed of the car as it leaves the table.

If a star's parallax angle is too small to measure, what can you conclude about the star's distance from the Earth?

Answers

Answer:

The star is too distant to be measured by parallax method. This happens when parallax angle is of the order of the least count of measuring system or less than that.
