I assume that in this item, we are asked to solve for the force exerted during the heartbeat. Force is the product of the mass and acceleration. To solve for the acceleration in this item, we divide the velocity by time.
a = 1 m/s / 0.2 s = 5 m/s²
Then, we multiply this by the mass (in kg)
F = (80 g / 1000 g/kg) x (5 m/s²)
= 0.4 kg m/s² = 0.4 J
Therefore, every hearbeat will take 0.4 J of force.
When evacuating victims and personnel currently facing danger to their lives, an establishment should have a safe evacuation routes. The evacuation route should be placed in the Exclusion Zone which means that it is a large site with obstructions and not safe until the safety area is reached. Another would be developing the Contamination Reduction Zone which is designed for individuals that are facing chemical dangers. Decontamination while inside the building is inadvised but would be applied in the arrival to the said zone. An access to potential routes should be available. Obstructions like locks, blocked doors are inadvisable. Routes should be free from items that are not needed within the area. Also, multiple routes that are separated from each other is recommended for evacuating numerous amount of people at the same time or when fire blocks one, there would be another choice available.
Answer:
d. Character displacement
Explanation:
Character displacement is the phenomenon in which the similar species living in the same geographical region with similar niches differentiate in order to reduce their niche overlap and avoid competitive exculsion. Just like in this case of two- spot and three -spot avenger beetles as their timmings for hunting is different where their ranges overlap. So it's the good example of character displacement,
This scientific law is called as Law of conservation of energy.
Sun is the primary source of energy .Energy once produced by the sun is then utilized by the organisms at various tropic levels. The energy is transferred from one organism to another. Energy is neither created nor destroyed. This is called as law of conservation of energy. Plants uses sunlight and make food and the energy is then transferred to organisms eating it. When the organism dies the energy is released into the environment. This cycle continues and the the law of conservation of energy is maintained.
Organs, cells with the same function make up tissue and tissue makes up the organ
