If a 4kg Bird is pushed by the window with a force of 60 N how fast is the bird accelerate?

LiRa [457]

Force=60N
Mass=4kg

$\\ \ast\sf\hookrightarrow Force=Mass\times Acceleration$

$\\ \ast\sf\hookrightarrow Acceleration=\dfrac{Force}{Mass}$

$\\ \ast\sf\hookrightarrow Acceleration=\dfrac{60}{4}$

$\\ \ast\sf\hookrightarrow Acceleration=15m/s^2$

what will be the focal lenght of a combined lens made by contact of two lenses of power +3D and -2D.

4vir4ik [10]

P_1=+3D
P_2=-2D

$\\ \bull\tt\dashrightarrow P=P_1+P_2$

$\\ \bull\tt\dashrightarrow P=+3D-2D=+1D$

Now

$\\ \bull\tt\dashrightarrow f=\dfrac{1}{P}$

$\\ \bull\tt\dashrightarrow f=\dfrac{1}{1}$

$\\ \bull\tt\dashrightarrow f=1m$
