Answer:
The pattern would spread out.
Explanation:
The fringe width is given by the relation
fringe width = λ L / D where λ is wavelength of light used, L is distance of wall from the source of light and D is slit separation.
If we increase λ , fringe width will increase and therefore pattern will spread out .
The correct choice would be
B) The Sun’s mass is much greater than Earth’s
The sun as we know has greatest mass in our solar system and lighter objects tends to orbit around the heavier objects. the mass of earth is very much smaller as compared to that of the sun. hence the earth orbits around the sun due to the force of gravitational attraction between the two objects.
Answer:
2m/s
Explanation:
The formula for acceleration can be found by [ a = f/m ]
We are given the force [ 100N ] and the mass [ 50g ].
We can use these values to solve for the acceleration.
a = 100/50
a = 2m/s
Best of Luck!
Answer:
k = 652 lb/ft
Explanation:
Given :
Weight of the collar = 1.6 lb
The upstretched length of the spring = 6 in
Speed = 16 ft/s
PA = 8 + 10
= 18 inch
Let the initial elongation be 
∴
= 18 - 6
= 12 inch = 1 foot

= 13.925 inch
Final elongation in the spring
inch = 0.66 feet
Applying the conservation of the mechanical energy between A and B is


![$\frac{1}{2}k[(1)^2-(0.66)^2]=\frac{1.6}{2}\times (16)^2-1.6 \times 32 \times \frac{5}{12}$](https://tex.z-dn.net/?f=%24%5Cfrac%7B1%7D%7B2%7Dk%5B%281%29%5E2-%280.66%29%5E2%5D%3D%5Cfrac%7B1.6%7D%7B2%7D%5Ctimes%20%2816%29%5E2-1.6%20%5Ctimes%2032%20%5Ctimes%20%5Cfrac%7B5%7D%7B12%7D%24)

Answer:
weight on Venus = 604.15 N
weight on Venus = 252.01 N
Explanation:
Given:
Weight on the earth , W = 150 lbs
now,
1 lbs = 4.45 N
thus,
W = 150 × 4.45 = 667.5 N
now, mass on the earth, m = 667.5/9.8 = 68.11 kg
now,
⇒ weight on Venus,
the acceleration due to gravity on venus = 8.87 m/s²
thus,
weight on Venus = mass × acceleration due to gravity on venus
or
weight on Venus = 68.11 × 8.87 = 604.15 N
⇒ weight on mars,
the acceleration due to gravity on mars = 3.70 m/s²
thus,
weight on Venus = mass × acceleration due to gravity on venus
or
weight on Venus = 68.11 × 3.70 = 252.01 N
