Answer:

V_{average}=  2.471  yards/s

Explanation:

We can calculate the average velocity thus:

V_{average} = \frac{D_{1}+D_{2} }{t_{1}+t_{2}}

Where

              D_{1} : First 25 yards

              t_{1}: Time to travel  D_{1}

              D_{2} : Seconds 25 yards

              t_{2}: Time to travel  D_{2}

Thus

V_{average} = \frac{25 + 25}{10.01 + 10.22}

V_{average}=  2.471  yards/s

FIRST ANSWER GET'S BRAINLIEST!!!!
Nuetrik [128]

Answer:

Earth's water is always in movement, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. Water is always changing states between liquid, vapor, and ice, with these processes happening in the blink of an eye and over millions of years.

Hope this helped!! :))

How many turns are in its secondary coil, if its input voltage is 120 V and the primary coil has 210 turns
Tasya [4]

Complete Question

How many turns are in its secondary coil, if its input voltage is 120 V and the primary coil has 210 turns.

The output from the secondary coil is  12 V

Answer:

The value  is  N_s  =  21 \  turns

Explanation:

From the equation we are told that

   The input voltage is  V_{in}  = 120 \ V

   The number of turns of the primary coil is N_p =  210 \  turn

    The output from the secondary is V_o =  12V

From the transformer equation

   \frac{N_p}{V_{in}}  =\frac{N_s}{V_o}

Here N_s is the number of turns in the secondary coil

=> N_s  =  \frac{N_p}{V_{in}}  *  V_s

=>N_s  =  \frac{210}{120}  *  12

=>N_s  =  21 \  turns
