Answer:c
Explanation:
The buoyancy force on toy depends upon the volume of toy under pool water.
According to Archimedes principle buoyant force on a floating body depends upon the weight of displaced liquid by object.
Buoyancy force is given by
where =density of fluid
V=volume of object under water
g=acceleration due to gravity
Answer:
Positive.
Explanation:
As a consequence of the photoelectric effect, electrons that will get hit by sufficiently energetic photons will abandon the metal surfaces exposed to bright sunlight. This decreases the negative charge of the surface, thus causing it to develop a positive net charge.
Is going to the west, because momentum is mass in motion so its motion is going to the direction of the netforce. Hope it helps
Answer:
Explanation:
Isaac Newton argued that the geometric nature of reflection and refraction of light could only be explained if light were made of particles, referred to as corpuscles, because waves do not tend to travel in straight lines.
The actions that would decrease the width of the central bright are decrease in the wavelength of the light and Increase in the width of the slit.
<h3>Wavelength of the light</h3>
The wavelength of the light is determined using the following formulas;
where;
- λ is wavelength
- d is width of the slit
- D is the distance of the screen
- y is distance between the central bright fringe and dark fringe
<h3>Actions that would decrease the width of the central bright</h3>
y = (λD) / (d)
- Decrease in the wavelength of the light
- Increase in the width of the slit
Thus, the actions that would decrease the width of the central bright are decrease in the wavelength of the light and Increase in the width of the slit.
