Kinetic energy = 0.5*M*V^2
Q7-
0.5*3*(2^2)= 6J
Q8a-
0.5*2*(2^2)= 4J
0.5*4*(3^2)=18J
the second ball has more kinetic energy.
Q8b-
at the max height, all the kinetic energy is converted to potential energy,
gravitational potential energy is = M*g*h
that theory would apply if you wanted to work out the maximum height achieved if the balls were thrown upward by rearranging. But, we are simply working out which ball will have more potential energy so:
First ball:
2kg*9.81(g)*10m = 196.2J
Second ball
4kg*9.81*10m= 392.4J
The second ball has more potential energy
Answer:
A wildfire is an unplanned fire that burns in a natural area such as a forest, grassland, or prairie. Wildfires are often caused by human activity or a natural phenomenon such as lightning, and they can happen at any time or anywhere. In 50% of wildfires recorded, it is not known how they started.
Answer:
The correct answer is - volume.
Explanation:
The volume is the measurement of the quantity of 3 D space that is enclosed by the matter that could be solid gas or liquid. The volume can be measure in the kg³, m³, cm³, l³ and other measurements.
Volume of the gas can measured as the place occupied by a particular matter. It is expressed in units like kilograms, centimeters, and litters.
Thus, the correct answer is - volume.
The one who developed the culturing technique to enrich for a certain population of microbial cells from a complex community based on a particular metabolic phenotype of interest is Martinus Beijerinck. The correct option is C.
<h3>What is culturing technique?</h3>
Culture methods involve collecting samples from the field and culturing them to detect the presence of microbes.
The number of microbial species and their influence on corrosion are estimated. Culture media for various microbes have been established.
Culturing is simply the process of growing microorganisms in special media in the laboratory. It entails the preparation of sterile medium, as well as the inoculation, incubation, and examination of microorganisms.
Martinus Beijerinck invented the technique for enriching a specific population of microbial cells from a complex community based on a specific metabolic phenotype of interest.
Thus, the correct option is C.
