Answer: 100N
Explanation: Given parameters:
Mass of the bowling ball = 20kg
Acceleration = 5m/s²
Unknown:
Amount of force applied = ?
Solution:
To solve this problem, we apply newton's second law of motion.
Force = mass x acceleration
Now insert the parameters and solve;
Force = 20 x 5 = 100N
The main relationship between emerging scientific ideas and open-mindedness is that for many new ideas to be accepted a population has to have an open mind, otherwise the new ideas are rejected without thought.
15. swell
16. swell
17. shrink
Salt = more density causing swelling
freshwater = shrink
i hope i am right on this!! let me know! thank you
Answer:
a. halophilic
Explanation:
Halophilic microorganisms have an absolute requirement for high salt concentration (NaCl concentration). These microbes grow well under the conditions of higher salt concentration but do not survive the lower salt concentrations. For example, the halobacteria are the archaeans that depend on high NaCl concentrations for growth and do not survive at a concentration below about 1.5 M NaCl.
According to the observations, the bacterium could not grow in the tube having a NaCl concentration of 0.5% but exhibits maximum growth under higher NaCl concentrations (15%). This means that the observed bacterium is a halophile or halophilic microbe.
Answer:
Pulmonary circulation refers to the circulation of blood in which deoxygenated blood is pumped from the heart to the lungs and oxygenated blood is returned to back to the heart. Pulmonary circulation only occurs between the heart and the lungs.
Systemic circulation refers to the circulation of blood in which oxygenated blood is pumped from the heart to the body and deoxygenated blood is returned back to the heart. Systemic circulation occurs between the heart and the entire body
