Answer: This is because water has a higher Specific Heat Capacity than air.
Explanation:
The specific heat capacity of an object measures how much heat will be required to change its temperature.
Water has a higher specific heat capacity than air, so the temperature of the water will remain fairly constant even though the air surrounding the water is experience temperature changes.
Since air has a lower Specific Heat Capacity than water, heat from the sun will readily heat it up in comparison to water.
Answer:
longer wavelength and lower frequency
shorter wavelength and greater frequency
Explanation:
f = v/l
l = wavelength
v = speed of wave
f = frequency
Answer:
The first diffraction maximum fringe will be at approximately 2.7 meters from the central maximum.
Explanation:
We can describe single slit diffraction phenomenon with the equation:
(1)
with θ the angular position of the minimum of order m respect the central maximum, a the slit width and λ the wavelength of the incident light. Because the distances between the first minima and the central maximum (
) are small compared to the distance between the screen and the slit (x), we can approximate 
, using this on (1):
solving for y
Note that 
is the distance between a minimum and the central maximum but we need the position of a maximum not a minimum, here we can use the fact that a maximum is approximately between two minima, so the first diffraction maximum fringe is between the minima of order 1 and 2, so we should find 
, 
add them and divide by two:
Answer:
3.67 m
Explanation:
A physical quantity is said to be vector quantity if it need a magnitude as well as direction for complete explanation.
It makes an angle 23.5 degree from positive X axis.
So, it's component along X axis is given by
bx = B Cos theta
bx = 4 × Cos 23.5
bx = 3.67 m
