- We know, acceleration is the change of velocity by time.
 - Velocity is the speed of an object which also indicates the direction.
 - Hence, acceleration is both dependant upon the speed as well as the direction.
 - So, if an object is moving at a constant speed in a changing direction, the acceleration will also change. It will not be zero.
 - An example is that of uniform circular motion.
 
Answer:
if an object is moving at a constant speed in a changing direction, the acceleration of the object will not be zero.
 
        
             
        
        
        
Answer:
Explanation:
Using the atomic mass of pluonium atoms (244 g/mol), you can calculate the number of atoms in 47.0 g. Then, knowing that each plutonium atom has 96 protons, you calculate the number of protons in the 47.0 g sample. Finally, using the positive charge of one proton, you calculate the total positive charge in the 47.0 g of plutonium.
<u>1. Number of atoms of plutonium in 47.0 g</u>
- Number of moles = mass / atomic mass = 47.0 g / 244 = 0.1926 moles
 
- Number of atoms = number of moles × 6.022 × 10²³ atoms/mol 
 
- Number of atoms = 0.1926 mol × 6.022 × 10²³ atoms/mol = 1.15998×10²³ atoms
 
<u>2. Number of protons</u>
- Number of protons = 1.15998×10²³ atoms × 96 protons/atom = 1.11385×10²⁵ protons
 
<u>3. Charge</u>
<u />
- Charge = charge of one proton × number of protons
 
- Charge = 1.602×10⁻¹⁹ C/proton × 1.11385×10²⁵ protons = 1.78×10⁶C
 
 
        
             
        
        
        
Behavior has at least six dimensions, which are: frequency, duration, latency, topography, locus, and force. Since the coach is recording how long it takes, the track coach is recording the duration behavior because duration is a synonym for time. Duration is your answer.
        
             
        
        
        
Elliptical, because the shape of the galaxy isn’t like the others. It is unique to its own and doesn’t have another to compare to
