Barometers have long been used to predict the weather. Jay and Jeff were responsible for recording the class weather data each d

ay in March. One day, they noticed that there was a rapid change in the barometric pressure. The barometric pressure dropped down very, very quickly. What type of weather could Jay and Jeff expect soon? A) fog B) rain C) clearing D) drop in temperature

Answer:

B) rain

Explanation:

The barometer is a device that is used to measure atmospheric pressure and, consequently, the height at which someone rises, as well as to approximately predict atmospheric changes. Thus, a rising barometer indicates an increase in air pressure, whereas a falling barometer indicates a decrease in air pressure.

In environments with low atmospheric pressure and, therefore, heat, the heated air tends to rise and, when reaching higher altitudes, condenses, forms clouds and precipitates. In this situation, the barometric pressure drops very, very quickly, indicating that a rain is coming.

Answer:

Fx = 35.36 N

Fy = 35.36 N

Explanation:

From the question,

The X component of the force is

Fx = Fcos∅.................. Equation 1

Where Fx = X component of the force, F = Force, ∅ = Angle to the horizontal.

Give: F = 50 N, ∅ = 45°

Substitute into equation 1

Fx = 50(cos45°)

Fx = 50(0.7071)

Fx = 35.36 N

Similarly,

For Y component

Fy = Fsin∅

Where F y = Y component

Fy = 50(sin45°)

Fy = 50(0.7071)

Fy = 35.36 N

A car is driving at 50 kilometers per hour. how far, in meters, does it travel in 2 seconds?
AveGali [126]
<span>Sure, Just change the 2 sec. into hrs. Since 1 hour = 3600 sec. then you can divide 2/3600 = 1/1800 hrs. Distance in kilometers = (Speed in km/hr * time in hrs) = 50*(1/1800)*1000 in meters = 27.77 meters</span>

Weightlessness is experienced by an astronaut in space. This means that the astronaut's muscles have to be stronger to move his
just olya [345]
The answer is false. The speed of the astronaut cancels out the force of gravity, causing a 'stationary freefall'. While under these effects, it is not required for an astronaut to 'strengthen' his body.

what is the main difference between a substance going through a physical change and one going through a chemical ?
Ainat [17]

Answer: Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.

The near point of an eye is 110 cm. A corrective lens is to be used to allow this eye to focus clearly on objects 26.0 cm in fro
irga5000 [103]

Answer:

The focal length of the lens is 34.047 cm

The power of the needed corrective lens is 2.937 diopter.

Explanation:

Distance of the object from the lens,u = 26 cm

Distance of the image from the lens ,v= -110 cm

(Image is forming on the other side of the lens)

Since ,lens of the human eye is converging lens,convex lens.

Using a lens formula:

\frac{1}{f}=\frac{1}{u}+\frac{1}{v}

\frac{1}{f}=\frac{1}{26 cm}+\frac{1}{-110 cm}

f = 34.047 cm = 0.3404 m

Power of the lens = P

P=\frac{1}{f}=\frac{1}{0.34047 m}=2.937 diopter
