The net force needed to accelerate a 200 kg piano is 50N
According to Newton's law of motion, the formula for the net force is calculated as:
∑F = ma
Given the following parameters
Mass = 200kg
acceleration = 0.25m/s²
Substitute the given parameters into the formula
∑F = 200 * 0.25
∑F = 50N
Hence the net force needed to accelerate a 200 kg piano is 50N

Answer:
4N
Explanation:
Given parameters:
Weight of stone when immersed in water = 18N
Weight of water displaced = 4N
Unknown:
Weight of the stone in air = ?
Solution:
To solve this problem, we employ the Archimedes' principles.
It states that the upward buoyant force on a body is equal to the weight of the fluid displaced.
The weight of the water displaced is equal to the weight of the body.
So, the weight of the stone in air = 4N
