10 mph i jus got it right on the test
Answer:

Explanation:
As we projected the balloon at speed vo at an angle of 29 degree
so the two component of velocity is given as


now we know that in x direction we have



in y direction we have



now we have

To solve this problem we will use the heat transfer equations, to determine the amount of heat added to the body. Subsequently, through the energy ratio given by Plank, we will calculate the energy of each of the photons. The relationship between total energy and unit energy will allow us to determine the number of photons
The mass of water in the soup is 477g
The change in temperate is

Use the following equation to calculate the heat required to raise the temperature:

Here,
m = Mass
c = Specific Heat


The wavelength of the ration used for heating is 
The number of photons required is the rate between the total energy and the energy of each proton, then

This energy of the photon is given by the Planck's equation which say:

Here,
h = Plank's Constant
c = Velocity of light
Wavelength
Replacing,


Now replacing we have,


Therefore the number of photons required for heating is 
the one with the big mustard-colored stripe across it is the correct choice.
Answer:
The laws of liquid pressure are
(i) Pressure inside the liquid increases with the depth from the free surface of the liquid.
(ii) Pressure is same at all points on a horizontal plane, in case of stationary liquid.
(iii) Pressure is same in all directions about a point inside the liquid.
(iv) Pressure at same depth is different in different liquids. It increases with the increase in the density of the liquid.
(v) A liquid will always seek its own level.
A Fluid is any liquid or gas or generally any material that cannot sustain a tangential, or shearing, force when at rest.
