That depends on the wavelength of the electromagnetic radiation.
-- If the waves are long, then we use them for radio, TV, and cellphones.
-- If the waves are shorter than that, then we use them for GPS in the car.
-- If the waves are shorter than that, then we use them to heat meatloaf
in the microwave oven.
-- If the waves are shorter than that, then they warm us and they
make our plants grow ... like the ones we eat.
-- If the waves are shorter than that, then our eyes use them to see with.
-- If the waves are shorter than that, then they tan our skin.
-- If the waves are shorter than that, then they can cause cancer on
our skin.
-- If the waves are shorter than that, then they can cause cancer and
other diseases in places inside our body.
Answer:
If you use the bicycle as a reference frame, your dog will appear to be moving backwards farther from you/your bicycle. Although the dog is sitting on one place, your bicycle is moving away from the dog
Explanation:
Answer:
Miller Indices are [2, 4, 3]
Solution:
As per the question:
Lattice Constant, C = 
Intercepts along the three axes:
Now,
Miller Indices gives the vector representation of the atomic plane orientation in the lattice and are found by taking the reciprocal of the intercepts.
Now, for the Miller Indices along the three axes:
a = 
b = 
c = 
To find the Miller indices, we divide a, b and c by reciprocal of lattice constant 'C' respectively:
a' = 
b' = 
c' = 
Answer:
Explanation:
95.0 km/hr = 26.39 m/s
65 km/hr = 18.06 m/s
Circumference of a tire is 0.9π m
77 revolutions is a distance of
77(0.9π) = 69.3π m
v² = u² + 2as
a = (v² - u²) / 2s
a = (18.06² - 26.39²) / (2(69.3π))
a = -0.85 m/s²
s = (v² - u²) / 2a
s = (0² - 26.39²) / 2(-0.85)
s = 409 m
