Answer:
the mass of the reactants must equal the mass of product
Answer:
Explanation:
mass of the crate = 5 kg
Force on crate = 0.22 N
now the speed of the crate after t = 10 s
Now the time taken by the crate to reach the orchestra pit
now we know that
According to the United Nations, there are <em>54 </em>countries in Africa today (late 2018).
You can solve this by using Newton's First Law or Newton's Second Law.
1) Newton's First Law or Inertia Law states that in the abscense of a net force acting over an object, this will not chage its state of movement, i.e it will remain at rest (if it is no moving) or with uniform movement (if the object is moving).
2) Newton's Second Law: Net force = mass * acceleration => acceleration = net force / mass = 0 / mass = 0.
Zero accelerations means rest or uniform movement.
First Law is implicit in Second Law.
