Final answer:
The weight of the giant cactus is 16856 Newtons.
Step-by-step explanation:
Weight is the force exerted on an object due to gravity. The weight of an object can be calculated using the formula:
Weight = Mass x Acceleration due to Gravity
In this case, the mass of the giant cactus is given as 1720 kg. The acceleration due to gravity is approximately 9.8 m/s^2 on Earth.
Using the formula, we can calculate the weight:
Weight = 1720 kg x 9.8 m/s^2
Weight = 16856 N
Therefore, the weight of the giant cactus is 16856 Newtons.
