A brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 780 N on him. The

stich3 [128]

Answer:

$f = 556.4 N$

Explanation:

Mass of the losing player with its all equipment is given as

M = 86 kg

Net force applied on him by another player is given as

F = 780 N

also we know that acceleration of the losing player is given as

$a = 2.6 m/s^2$

now by Newton's 2nd law we will have

$F - f = ma$

$780 - f = 86(2.6)$

$780 - f = 223.6$

$f = 556.4 N$

One circuit contains only an ac generator and a resistor, and the rms current in this circuit is IR. Another circuit contains on

snow_tiger [21]

Answer:

1/3 times.

Explanation:

Let V₀ be the peak voltage .

IR ( rms ) = ( V₀ / √2 R )

R is value of resistance

IC = ( V₀ ωC / √2 )

( 1 / ωC is reactance of capacitance in ac circuit )

$\frac{I_R}{I_C} =\frac{\frac{V_0}{\sqrt{2}R } }{\frac{V_0\omega C}{\sqrt{2} } }$

= $\frac{I_R}{I_C} = \frac{1}{\omega C R}$

When frequency is tripled angular frequency will also be tripled

hence the ratio $\frac{I_R}{I_C}$ becomes 1/3 times.
