This is true. There is a downward force on the table that stabilizes the rock to stay there.
Since the factory will be producing 100,000 kilograms of cement, using the relation 1000 kg of cement = 900 kg of CO2, then the factory will be emitting 90,000 kg of CO2 at the same time. To counteract the emission, a tree can remove 6 kg of CO2 per day. Dividing 90,000 kg by 6 kg to know the number of trees, we need 15000 trees to counter the emission. Since 1 acre of land holds 200 trees, we need 75 acres of land to hold the 15000 trees.
The type of force that Koi is demonstrating in this position would be: <span>static friction
</span><span>static friction is a type of force that created when a stationary object is placed on the surface where it's resting. It also defined the amount of force you need to overcome before you could move the object</span>
