A parcel of air is being forced up the windward side of a 7,000-foot-high mountain. The parcel has a temperature of 91.0°F at 0

feet in elevation. If the LCL is located at 5,000 feet, what is the temperature of this parcel of air at 1,000 feet?

Answer:

Temperature of parcel at 1000 ft is 85.5°F

Explanation:

Temperature of parcel at 0 ft =T₁ = 91.0°F

Dry adiabatic rate = 5.5°F/100 ft

Temperature of parcel at H₂ (1000 ft) = T₂ =?

Height of LCL = 5000 ft

As (1000<5000), so using the formula for parcel below or at the LCL i.e.

                        T_{2}=T_{1}-\Delta T

                        \Delta T =H_{2}\times DAR

                        \Delta T=1000(\frac{5.5}{1000})

                        \Delta T= 5.5^{o}

                        T_{2}=91.0-5.5

                        T_{2}=85.5^{o}F

When a boat is placed in liquid, two forces act on the boat. Gravity pulls the boat down with a force equal to the weight of the
wel

Answer:

the fraction of submerged volume is equal to the ratio of the densities of the body between the density of the fluid.

Explanation:

This is a fluid mechanics problem, where as the boat is in equilibrium with the pushing force we can write Newton's second law

                  B- W = 0

                  B = W

           

the thrust force is equal to the weight of the liquid that is dislodged

                  B = ρ g V

we substitute

             ρ g V = m g

             V = m /ρ_fluid          1

we can write the mass of the pot as a function of its density

             ρ_body = m / V_body

            m = ρ_body  V_body

             V_fluid / V_body = ρ_body / ρ _fluid         2

Equations 1 and 2 are similar, although 2 is easier to analyze, the fraction of submerged volume is equal to the ratio of the densities of the body between the density of the fluid.

The effect appears the pot as if it had a lower apparent weight

if the Horse and Rider have a combined mass of 572 kg what force would be required to accelerate them 5 kph per second
Vlad [161]

Answer:

   Force required to accelerate = 794.44 N

Explanation:

 Force required = Mass of horse x Acceleration of horse

 Mass of horse and rider, m=   572 kg

 Acceleration of horse and rider, a = 5 kph per second

                                      =\frac{5*1000}{60*60} =1.39 m/s^2

  Force required = ma

                             = 572 x 1.39 = 794.44 N

  Force required to accelerate = 794.44 N

The acceleration due to gravity on the moon is about 1/6 of the acceleration due to gravity on the earth. A net force F acts hor
uysha [10]

Answer:

c.a_m

Explanation:

We are given that

Acceleration due to gravity on the moon=a_m

Acceleration due to gravity on the earth=a_e

g_m=\frac{1}{6}g_e

Net force due to am on an object on moon=F_{net}=ma_m

There is no friction and no drag force and there is no gravity involved

Then, the force acting on an object on earth=F=ma_e

F=F_{net}(given)

ma_m=ma_e

a_e=a_m

Hence, option c is true.

How does reflection differ from refraction and diffraction?
shtirl [24]

Answer: Reflection is the only process in which the wave does not continue moving forward.

Explanation:

Reflection is a process in which the direction of the wave changes when it is exposed to a bounce off barrier. Refraction can be defined as the change in the direction of the wave when the wave passes through one medium to another. Diffraction is a process in which the direction of the wave changes when the wave passes through a particular opening near the barrier.

What happens when a light ray is parallel to the principal axis ?
Phantasy [73]

Answer:

Any incident ray traveling parallel to the principal axis of a converging lens will refract through the lens and travel through the focal point on the opposite side of the lens. ... These rays of light will refract when they enter the lens and refract when they leave the lens.

Hope this helps...
