Which best describes the protection efforts for coral reefs?

Which best describes the protection efforts for coral reefs? Answer. Answer: Minimize use of fertilizers. Can the coral reefs be saved? Active and targeted restoration by creating new ways to outplants many corals at once and other interventions will reduce the decline of coral populations and support coral reef ecosystems in changing environmental conditions. Monitoring, […]

Will the next force be equal to zero?

Will the next force be equal to zero? The net force is the vector sum of all the forces acting on an object. When an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero. A vector can only have zero magnitude if all of its […]

What are the components of centripetal force?

What are the components of centripetal force? As a bucket of water is tied to a string and spun in a circle, the tension force acting upon the bucket provides the centripetal force required for circular motion. As the moon orbits the Earth, the force of gravity acting upon the moon provides the centripetal force […]

Why magnesium ion has a charge of 2+?

Why magnesium ion has a charge of 2+? Explanation: Magnesium is under group 2 that also has a valence electron of 2. To achieve stability and to follow the octet rule, these 2 electrons in the outer shell will be removed making this atom into an ion with a 2+ charge. Why is the charge […]

What makes water drinkable?

What makes water drinkable? Filtration – The clear water on top passes through filters composed of sand, gravel and charcoal to remove dissolved particles such as dust, parasites, bacteria, viruses and chemicals. Disinfection – Chlorine or chloramine is added to kill parasites, bacteria, viruses and germs. How do you sanitize water? Boil water, if you […]

What is needed to stop a moving object?

What is needed to stop a moving object? The force stopping the object’s motion might be an obvious one – the ground! Friction is a force that slows or stops motion. Friction is the resistance to motion created by two objects rubbing against each other (the sled and the snow, for instance). Even air causes […]
