Answer:
705.6 m
Explanation:
time, t = 12 sends
initial velocity, u = 0
Acceleration due to gravity, g = - 9.8 m/s^2
As the object is falling freely so the initial velocity is zero.
Let the distance traveled by the body is h in time t = 12 s.
Use second equation of motion
Ad the distance is downwards so take it as negative
So,
h = 705.6 m
Thus, the distance traveled in 12 second is 705.6 m
Answer:
44 ohm, 145 ohm
Explanation:
R = 44 ohm, L = 2.2 mH = 2.2 x 10^-3 H
At f = 60 Hz
XL = 2 π f L = 2 x 3.14 x 60 x 2.2 x 10^-3 = 0.82896 ohm
Impedance,
Z = 44 ohm
At f = 10 kHz = 10000 Hz
XL = 2 π f L = 2 x 3.14 x 10000 x 2.2 x 10^-3 = 138.16 ohm
Impedance,
Z =1 45 ohm
Answer is D..by applying formula W=Fs ..10×2 = 20
If both particles have the SAME electrical charge, then they repel.
If they have DIFFERENT electrical charge, then they attract.
Protons have + charge .
Electrons have - charge .
So two protons (A) or two electrons (D) push apart.
One proton and one electron (C) pull together.
The blue line with triangles are a cold front. The red line with half circles are a warm front. The black H is high pressure. The black L is low pressure. The black dot is overcast skies. Finally the white circle with a line down and 4 lines off of that line is 40-knot wind
idk and dont understand
