Answer:
g = 66.7 ms^-2 (3 s.f.)
Explanation:
Potential Energy -> PE
m -> mass
g -> acceleration due to gravity
h -> height
using the formula, PE = mgh
600 = 3 × g × 3
9g = 600
g = 600/9
g = 66.666
g = 66.7 ms^-2 (3 significant figures)

A student is measuring the lengths of caterpillars for an experiment. She measures 100 caterpillars using a ruler that measures to the nearest centimeter. Which statement describes a change that could help improve the results of her experiment? O A. Her measurements will be more precise if she measures an additional 100 caterpillars. O B. Her measurements will be more accurate if she measures an additional 100 caterpillars. O C. Her measurements will be more accurate if she uses a ruler that measures to the nearest millimeter. O D. Her measurements will be more precise if she uses a ruler that measures to the nearest millimeter Please help
Answer:
B and C
Explanation:
The student's measurement would be more accurate if she can measure an additional 100 caterpillars and be more precise if she uses a ruler that measures to the nearest millimeter.
Accuracy refers to the closeness of measurement or group of measurements to the true value while precision is the closeness of repeated measurements.
The accuracy of a measurement is increased by increasing the number of sample measurements. The more the sample measurements, the lesser the deviation of the mean from the true value.
The precision of a measurement is increased by being able to measure small differences. Hence, a ruler that measures to the nearest millimeter would be more precise than a ruler that can only measure in centimeter.
The correct option is B and C.

Why does cell division remain important to an adult organism even after it is fully developed?
Answer:
Cell division prevents cancers, and is something that in humans and in other adult organisms as well prevents old age.
There are many more complex mechanisms that contribute to old age and cancers, but if cell division slows down an organism reaches the end of its life.
Every set of cells has a limited amount of divisions it can do. literally every organism from the moment of conception is dying.
a skaterboarder is traveling 12 m/s down a hill. The skaterboarder cradshed and slid to a stop in 2.0 seconds. What was the rider's acceleration?
PLEASE!!!
The skateboarder is travelling with a initial velocity of 12 m/s and slid to stop in the next 2.0 seconds. The acceleration of the skateboarder will be -6 m/s².
What is Acceleration of an object?Acceleration of a body is the change in the velocity with respect to time. Acceleration depends upon factors such as time, initial velocity, final velocity, and distance travelled by the object.
In the given question, the skateboarder is travelling with a initial velocity (u) of 12 m/s
Time (t) after which he comes to a stop is 2.0 seconds
The skateboarder stops and comes to rest therefore, the final velocity (v) of the skateboarder will be zero
The acceleration (a) of the skateboarder can be calculated by the formula:
a = (v - u)/t
where, a = acceleration of the object
v = final velocity of the object
u = initial velocity of the object
t = time elapsed
a = (0 - 12)/2.0
a = -12/2.0
a = -6.0m/s²
Here, the acceleration is negative because the body comes to rest at the end after acceleration.

What is the primary source of energy for food chains in an ecosystem? decomposers producers consumers the sun
Answer: sun
Explanation:
3.1 The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water.
Answer:
I believe that the sun is the main source of energy .. it is a source of energy for plants that are eaten by animals other than eating meat. As for animals that eat meat, they feed on other animals .. I believe that the beginning of the chain is the sun

Life can exist under frozen surfaces in polar seas because…
Answer:
Life exit under frozen surfaces in polar seas because of the anomalous behavior of water.
Explanation:
Water behaves irregularly, which helps in preventing the total freezing of seas during winter.
Since water has its highest density at [tex]4^{o}[/tex]C, the surface of seas freezes while the lower regions or layers is in form of liquid. During winter, as the temperature decreases to [tex]4^{o}[/tex]C, the layer of water with highest density sinks to the bottom while those that are less dense floats to the top. Thus when the surface temperature is below [tex]0^{o}[/tex], the lower layers under the frozen surface are at temperature range between [tex]1^{o}[/tex]C to [tex]4^{o}[/tex]C
