Answer:
Y = 0.0254 m = 25.4 mm
Explanation:
The formula for the fringe spacing in Young's Double-slit experiment is given by the following formula:

where,
Y = fringe spacing = 0.0176 m
λ = wavelength = 425 nm = 4.25 x 10⁻⁷ m
L = Distance between screen and slits
d = slit separation
Therefore,

Now, for:
λ = 614 nm = 6.14 x 10⁻⁷ m

<u>Y = 0.0254 m = 25.4 mm</u>
Answer:

Explanation:
they are a bunch of things functioning together
Answer:
Newton's First Law of Motion.
Explanation:
Newton's first law of motion states that an object continues to stay in its state of rest, or of uniform motion, until acted upon by an external force.
So in the case of the golf ball here, the ball stays in its state of rest, on the tee, until the golf club hits it, i.e. , applies an external force on it.
Hence we can say that Newton's First Law of Motion is the principle which is most suitable for explaining this phenomenon.
Answer:
2.43J
Explanation:
Given parameters:
Mass of the arrow = 0.155kg
Velocity = 31.4m /s
Unknown:
Kinetic energy when it leaves the bow = ?
Solution:
The kinetic energy of a body is the energy in motion of the body;
it can be derived using the expression below:
K.E =
m v²
m is the mass
v is the velocity
Solve for K.E;
K.E =
x 0.155 x 31.4 = 2.43J
Explanation:
It is given that,
The period of the carrier wave, T = 0.01 s
Let f and
are frequency and the wavelength of the wave respectively. The relationship between the time period and the frequency is given by :


f = 100 Hz
The wavelength of a wave is given by :



So, the frequency and wavelength of the carrier wave are 100 Hz and
respectively. Hence, the correct option is (c).
