The value of the constant K in the temperature equation is 32.

The given parameters:

  • F (C) = \frac{9}{5} C \ + K
  • 40⁰C corresponds to 104 ⁰F

The value of K for which the value of the temperature at 40 degrees Celsius corresponds to 104 degrees Fahrenheit is calculated as follows;

F(C) = \frac{9}{5} C \ + \ K \\\\104 = \frac{9}{5} (40) \ + \ K\\\\104 = 72 \ + \ K\\\\104 - 72 = K\\\\32 = K

Thus, the value of the constant K in the temperature equation is 32.

Answer:

Electric field at a distance of 1.45 cm will be 172.41\times 10^4N/C

Explanation:

We have given the distance d = 1.45 cm = 0.0145 m

And the potential difference V=2.5\times 10^4volt

There is a relation between potential difference and electric field

Electric field at a distance d due to a potential difference is given by

E=\frac{V}{d}, here E is electric field, V is potential difference and d is distance

So E=\frac{V}{d}=\frac{2.5\times 10^4}{0.0145}=172.41\times 10^4N/C

During a tennis volley, a ball that arrives at a player at 40 m/s is struck by the racquet and returned at 40 m/s. The other pla
Butoxors [25]

Answer:Racquet force is twice of Player force

Explanation:

Given

ball arrives at a speed of u=-40\ m/s

ball returned with speed of v=40\ m/s

average Force imparted by racquet on the ball is given by

F_{racquet}=\frac{m(v-u)}{\Delta t}

where m=mass\ of\ ball

\Delta t=time of contact of ball with racquet

F_{racquet}=\frac{m(40-(-40))}{\Delta t}

F_{racquet}=\frac{80m}{\Delta t}-----1

When it land on the player hand its final velocity becomes zero and time of contact is same as of racquet

F_{player}=\frac{m(0-40)}{\Delta t}

F_{player}=\frac{-40m}{\Delta t}-----2

From 1 and 2 we get

F_{racquet}=-2F_{player}

Hence the magnitude of Force by racquet is twice the Force by player
