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:
139.6m/s
Explanation:
Calculate the tension first, T=m*g
mass(m): 1750kg, gravity(g): 9.8m/s^2
T= 1750*9.8
=17150N
Then calculate the wave speed using the equation v = √ (T/μ)
v= √(17150N)/(0.88kg/m)
=139.6m/s
<span>Option C. The sodium vapor lamp is a gas discharge lamp that uses sodium vapor for the production of light. It is an efficient lighting source that provides lumens per watt and produces bright yellow. It has a monochromatic light that makes its applications are reduced. It is used in street lighting, streets, highways, etc.</span>
