Answer:

It reveals that light is a wave

Explanation:

Diffraction is the property of a wave in which there is a bending of the wave about the corners of an obstacle or aperture into the geometrical shadow of the obstacle or aperture.

This simply implies that a wave bends or spreads out when it passes through openings. Since the light diffracts through small slits and diffraction has been shown to occur in water waves and sound waves, this property of diffraction can only be characteristic of a wave and thus, this evidence reveals that light is a wave.

A manometer containing oil (rho = 850 kg/m3) is attached to a tank filled with air. If the oil-level difference between the two
White raven [17]

Answer:

P_{abs}=107172.35Pa\\  P_{abs}=107.172kPa

Explanation:

Given data

P_{a}=98kPa\\ p_{oil}=850kg/m^{3}\\  h=110cm=1.10m

To find absolute pressure of air in the tank.We must find the pressure athe parallel point from the right tube

So

P_{abs}=P_{a}+hp_{oil}g\\P_{abs}=98000Pa+(1.10m*850kg/m^{3}*9.81 )\\P_{abs}=107172.35Pa\\  P_{abs}=107.172kPa

A compact car, mass 664 kg, is moving at 19 km/h toward the east. What is the car's momentum in kg x m/s?
Natasha2012 [34]

Answer:

3504.4 kgm/s

Explanation:

First, convert km/hr to m/s:

19 km/hr x 1000m/1km x 1/60min x 1/60s = 5.28 m/s

p = mv

p = (664 kg)(5.28 m/s) = 3504.4 kgm/s

What are 2 things Lithium, Beryllium, and Boron, have in common?
ivann1987 [24]

Answer:

larger atomic radii because they are on the far left, the s-block, of the periodic table. -The ionic radii increase as you go down groups on the periodic table. -Lithium and Beryllium are not examples of this trend because they are both in 2s.

A horse pulls on a carriage. By Newton's third law, the carriage pulls back on the horse with equal force. Why do the action and
Andrews [41]

Answer:

By Newton's third law the cart must then exert an equal and opposite force on the horse. ... If it doesn't accelerate, and it started it rest, it must remain at rest (by the definition of acceleration), and therefore no matter how hard the horse pulls, it can never move the cart
