The distance mirror M2 must be moved so that one wavelength has produced one more new maxima than the other wavelength is;
L = 57.88 mm
We are given;
Wavelength 1; λ₁ = 589 nm = 589 × 10⁻⁹ m
Wavelength 2; λ₂ = 589.6 nm = 589.6 × 10⁻⁹ m
We are told that L₁ = L₂. Thus, we will adopt L.
Formula for the number of bright fringe shift is;
m = 2L/λ
Thus;
For Wavelength 1;
m₁ = 2L/(589 × 10⁻⁹)
For wavelength 2;
m₂ = 2L/(589.6)
Now, we are told that one wavelength must have produced one more new maxima than the other wavelength. Thus;
m₁ - m₂ = 2
Plugging in the values of m₁ and m₂ gives;
(2L/589) - (2L/589.6) = 2
divide through by 2 to get;
L[(1/589) - (1/589.6)] = 1
L(1.728 × 10⁻⁶) = 1
L = 1/(1.728 × 10⁻⁶)
L = 578790.67 nm
L = 57.88 mm

an electric field is 16 n/c northwest. that makes it a
a) magnitude
b)direction
c)vector
d)scalar
16 n/c to the northwest lies an electric field. hence it qualifies as a direction. Thus, the correct response is (b). It is assumed that the field's direction corresponds to the direction in which a positive test charge should experience force.
With a positive point charge, the electric field radiates outward, whereas with a point charge that's negative, it radiates in.
How big and which way is the electric field pointing?
A positive point charge is pointed directly away by the electric field, while a negative point charge is pointed directly inside the opposite direction. When you go away again from point charge, the power of the electrical field diminishes as 1 / r 2 1/r21, slash, r, square.

HOPE IT HELPS YOU!!For a horizontally projectile object if the initial velocity doubled, the Vertical displacement (angle y) will be :
Answer:
Unchanged
Explanation:
horizontal projection always has initial vertical velocity equal to zero.
gravity works pretty much the same at any point on earth and will accelerate any falling object at the same rate traveling the same vertical distance in the same time. Neglecting air resistance of course.
By the way, Δy is read "delta y" not "angle y" which would be "∠ y"
delta represents a change in something, in this case the y coordinate.
Which force, in real life, will have the least effect on a bowling ball rolling down a lane toward bowling pins?
A) magnetism
B) air resistance
C) gravity
D) friction
Answer:
Its Friction
Explanation:
the pins are not floating and they are not a magnet and not involved with air
The force, in real life, that will have the least effect on a bowling ball rolling down a lane toward bowling pins is magnetism. The correct option is A.
What is magnetism?Magnetism is basically the force which indeed magnets exert when they attract or even repel one another. The movement of electric charges resulting in magnetism.
Every substance is composed of tiny units referred to as atoms. Each atom contains electrons, which are charged particles.
To increase stability, the pins themselves have a low center of gravity. Because they are spherical in shape, they can roll and strike other pins in a variety of directions.
The force acting on the bowling ball is friction and air resistance. The friction force is equal to the friction coefficient multiplied by the normal force, and thus mass times acceleration.
Thus, the correct option is A.

Hi there!
We know that the acceleration due to gravity is given by:
[tex]g = \frac{Gm_o}{r^2}[/tex]
We can plug in the given values assuming that the above equation represents the earth's gravitational acceleration:
[tex]g_{planet} = \frac{G(2m)}{(3r)^2} = \frac{2}{9}(\frac{Gm}{r})[/tex]
Since the acceleration due to gravity of this other planet is 2/9th of the acceleration due to gravity on earth, the weight:
W = mg, will also be 2/9ths of that of earth. The correct answer is C.

A ball is dropped from a height of 10m. At the same time, another ball is thrown
vertically upwards at an initial speed of 10m/sec. How high above the ground will the two balls
collide?
5.1 m
Explanation:
Let's set the ground as our reference point. Let's also call the dropped ball to be ball #1 and its height above the ground at any time t is given by
[tex]y_1 = 10 - \frac{1}{2}gt^2[/tex] (1)
where 10 represents its initial height or displacement of 10 m above the ground. At the same time, the displacement of the second ball with respect to the ground [tex]y_2,[/tex] is given by
[tex]y_2 = v_0t - \frac{1}{2}gt^2[/tex] (2)
At the instant the two balls collide, they will have the same displacement, therefore
[tex]y_1 = y_2 \Rightarrow 10 - \frac{1}{2}gt^2 = v_0t - \frac{1}{2}gt^2[/tex]
or
[tex]v_0t = 10\:\text{m}[/tex]
Solving for t, we get
[tex]t = \dfrac{10\:\text{m}}{v_0} = \dfrac{10\:\text{m}}{10\:\text{m/s}} = 1\:\text{s}[/tex]
We can use either Eqn(1) or Eqn(2) to hind the height where they collide. Let's use Eqn(1):
[tex]y_1 = 10\:\text{m} - \frac{1}{2}(9.8\:\text{m/s}^2)(1\:\text{s})^2[/tex]
[tex]\:\:\:\:\:\:\:= 5.1\:\text{m}[/tex]

Which of Newton’s Laws of motion help explain the following scenario?
A paddle wheel boat pushes on the water and the water pushes back causing the boat to move
Answer:
Newton #3
Explanation:
For every action there is an equal and opposite reaction.
A different group is worried that the motion detector will not
effectively track the falling object, so they decide to roll a round
object down a ramp instead of dropping it. They measure the initial
height to calculate gravitational potential energy, use the motion
detector to track the final velocity, and calculate the kinetic energy of
the object at the end.
Despite all their careful measurements, it appears that energy is not
conserved! The object is not moving as fast at the bottom as the
initial gravitational potential would have led them to predict. Which
of the following suggestions is possible? Select all that apply.
The energy is not conserved because:
1. Energy may still be leaving the system through friction.
2. There could be measurement error that account for the missing energy
Given that a different group roll a round object down a ramp instead of dropping it. They measure the initial height to calculate gravitational potential energy, use the motion detector to track the final velocity, and calculate the kinetic energy of the object at the end.
Despite all their careful measurements, it appears that energy is not
conserved because
1. Energy may still be leaving the system through friction. In which the energy lost will be converted to thermal energy
2. There could be measurement error that account for the missing energy. The may occur due to systematic error or parallax error
The object is not moving as fast at the bottom as the initial gravitational potential would have led them to predict. This is not as a result of rotational energy. There is nothing like rotational energy.
