Answer:
20
Explanation:
The acceleration in this problem is 20
Acceleration is defined as the rate of change of velocity with time. When a force is exerted on a body and the net force is greater than zero, it begins to accelerate.
- A golf ball often accelerate from rest when being hit.
- Its initial velocity in this instance is usually zero.
- As it is hit, the acceleration increases to a point where it begins to tend towards zero is momentum decreases.
- From the given problem, the mass of the ball is 0.2kg and the acceleration is 20m/s²
Answer:
171 moles of sodium chloride
Explanation:
Number of moles = mass/molar mass
Molar mass of sodium chloride = 58.5 g/mol
mass of sodium chloride = 10 Kg or 10,000 g
Now, to obtain the number of moles of sodium chloride;
Number of moles = 10,000 g/58.5 g/mol
Number of moles = 171 moles of sodium chloride
Cloned material have the same genetic make up because they are formed after one egg cell is fertilized but spilts to form embryos.
