Wavelength is defined as distance between two troughs or two crests !!
so in this wavelength is 4 metres !!
A region around a charged particle or object within which a force would be exerted on other charged particles or objects
Answer:
If an object has a fast velocity, the dots on a ticker tape diagram will be far apart.
Answer:
The mass of the object is 5.045 lbm.
Explanation:
Given;
kinetic energy of the object, K.E = 1558.71 ft.lbf
velocity of the object, V = 141 ft/s
The kinetic energy of the object is calculated as;


Therefore, the mass of the object is 5.045 lbm.
