21N
Explanation:
Given parameters:
Mass of wagon = 14kg
Acceleration = 1.5m/s²
Unknown:
Net force on wagon = ?
Solution:
Force is a pull or push on a body that causes a body to change its state. It is expressed as:
Force = mass x acceleration
Force on wagon = 14 x 1.5 = 21N

That is a really good question, cheese is stretchy when it is hot is because when you heat it up, it liquefies which makes it stretch. it doesn't stretch when it is cold because it is a solid and solids usually do not stretch.
The frequency of a wave is the number of waves that passes through a point in a certain time. The less waves that pass in a period of time the lower the frequency of the wave. The more waves that pass in a period of time the higher the frequency of the wave. When measuring wave length the time period used is usually one second.
Answer:
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
