Radda [10]3 years ago

Answer:

Explanation:

Given parameters:

Distance covered  = 16m

Time  = 6s

Initial velocity  = 0m/s

Unknown:

Magnitude of the acceleration of the runner = ?

Solution:

To solve this problem, we have to apply the right motion equation which is given below;

     S  = ut + \frac{1}{2}  at²  

S is the distance

u is the initial velocity

t is the time taken

a is the acceleration

 Now, insert the parameters and solve for acceleration;

      16  = (0 x 6) + \frac{1}{2} x a x 6²

     16  = 18a

     a  = \frac{16}{18}   = 0.89m/s²

A 500-watt vacuum cleaner is plugged into a 120-volt outlet and used for 30 minutes. How much current runs through the vacuum?
Ymorist [56]

     Power  =  (voltage) x (current)

       500 W  =  (120 v) x (current)

     Current  =  (500 w) / (120 v)  =  4-1/6 amperes .

Power and current are both rates.
Power is the rate of using energy ... joules per second.
Current is the rate of flowing charge ... coulombs per second.
Neither quantity depends on how long you keep it up.
They're both going on continuously while the vacuum is running.
