Answer:0.5m/s^2
Explanation:
Force=10N mass=20kg acceleration=?
Acceleration=force/mass
Acceleration=10/20
Acceleration=0.5m/s^2
Start by facing East. Your first displacement is the vector
<em>d</em>₁ = (225 m) <em>i</em>
Turning 90º to the left makes you face North, and walking 350 m in this direction gives the second displacement,
<em>d</em>₂ = (350 m) <em>j</em>
Turning 30º to the right would have you making an angle of 60º North of East, so that walking 125 m gives the third displacement,
<em>d</em>₃ = (125 m) (cos(60º) <em>i</em> + sin(60º) <em>j</em> )
<em>d</em>₃ ≈ (62.5 m) <em>i</em> + (108.25 m) <em>j</em>
The net displacement is
<em>d</em> = <em>d</em>₁ + <em>d</em>₂ + <em>d</em>₃
<em>d</em> ≈ (287.5 m) <em>i</em> + (458.25 m) <em>j</em>
and its magnitude is
|| <em>d</em> || = √[ (287.5 m)² + (458.25 m)² ] ≈ 540.973 m ≈ 541 m
Answer:
(a) The spacing of the fringes will remain unchanged if there is a change in the width of the slits but no change in the centers' distance.
(b) However, if the slits are made to be broader, wave interference will create less contrast. There will be a reduction in the intensity of the bright fringes.
Explanation:
The equation for the double slit experiment is shown below:
mλ = dsinθ
Thus: (a) The spacing of the fringes will remain unchanged if there is a change in the width of the slits but no change in the centers' distance.
(b) However, if the slits are made to be broader, wave interference will create less contrast. There will be a reduction in the intensity of the bright fringes.
I think that the answer is color.
The answer is
D. turn into white dwarfs
