Answer:
λ = 5.85 x 10⁻⁷ m = 585 nm
f = 5.13 x 10¹⁴ Hz
Explanation:
We will use Young's Double Slit Experiment's Formula here:
where,
λ = wavelength = ?
Y = Fringe Spacing = 6.5 cm = 0.065 m
d = slit separation = 0.048 mm = 4.8 x 10⁻⁵ m
L = screen distance = 5 m
Therefore,
<u>λ = 5.85 x 10⁻⁷ m = 585 nm</u>
Now, the frequency can be given as:
where,
f = frequency = ?
c = speed of light = 3 x 10⁸ m/s
Therefore,
<u>f = 5.13 x 10¹⁴ Hz</u>
The correct answer for this question is "Two-car length rule." While driving, the principle that you should be used to keep the appropriate distance between your vehicle and the vehicle in front of you is to follow the <span>Two-car length rule. This rule is to be followed for safety.</span>
d. both a and b
Explanation:
Seismic waves are both transverse and compressional or longitudinal waves.
A seismic wave is an elastic wave that causes a sudden disturbance in earth materials.
- Seismic waves are both longitudinal and transverse waves.
- There are two main types of seismic waves which are the surface and body waves.
- The surface waves runs on the earth surface. These are the rayleigh and love waves.
- The surface waves causes damages on the earth surface as they are both longitudinal and transverse.
- Body waves moves within the earth surface. They are p-waves and s-waves.
- P-waves are longitudinal or compressional waves that propagates within the earth surface.
- S-waves are transverse waves that moves perpendicularly to their direction of propagation.

Answer:
Magnetic force, F = 0.262 N
Explanation:
It is given that,
Magnetic field of an electromagnet, B = 0.52 T
Length of the wire, 
Current in the straight wire, i = 10.5 A
Let F is the magnitude of force is exerted on the wire. The magnetic force acting on an object of length l is given by :
F = 0.262 N
So, the magnitude of force is exerted on the wire is 0.262 N.
It would do exactly what a rock or a frisbee does when you toss it.
After the engines cut off, it couldn't get any more energy from
anywhere, and after that, as it pushed air aside to get through,
and had air molecules scraping against it, those would slowly
rob kinetic energy from it. Sooner or later it would run out of
kinetic energy, start falling, and it would eventually make either
a big 'SPLOOSH' or else a big 'CRUNCH', depending on exactly
where it returned to Earth's surface.
