A. True
if cold air is replacing warm air it is a cold front and vice versa.

Answer:

The Answer is B) False

Explanation:

The key word there is overtakes.

A weather front is a boundary separating two masses of air of different densities, and is the principal cause of meteorological phenomena outside the tropics.

Air masses create weather as they are moved by winds around the globe. Fronts develop at the boundary where two air masses with different temperatures—and, usually, different humidities—come into contact with each other or in <u>essence collide</u>.

The term <em>front</em> was suggested the creator of the word because the <u>collision </u>of two air masses reminded them of a battlefront during a military operation.

So air masses collide NOT overtake each other in order to form a front.

Cheers!

An object is 30 cm in front of a converging lens with a focal length of 10 cm. Use ray tracing to determine the location of the
poizon [28]

Answer:

Inverted

Real

Explanation:

u = Object distance =  30 cm

v = Image distance

f = Focal length = 10 cm

Lens Equation

\frac{1}{f}=\frac{1}{u}+\frac{1}{v}\\\Rightarrow \frac{1}{f}-\frac{1}{u}=\frac{1}{v}\\\Rightarrow \frac{1}{v}=\frac{1}{10}-\frac{1}{30}\\\Rightarrow \frac{1}{v}=\frac{1}{15}\\\Rightarrow v=15\ cm

As, the image distance is positive the image is real and forms on the other side of the lens

m=-\frac{v}{u}\\\Rightarrow m=-\frac{-15}{30}\\\Rightarrow m=-0.5

As, the magnification is negative the image is inverted

The frequency of the George Washington Bridge is 2.05 Hz. What is its period?
Zina [86]

Answer: 0.5 seconds

Explanation:

Given that:

Frequency of the George Washington Bridge F = 2.05 Hz

Period T = ?

Recall that frequency is the number of cycles a wave can complete in one second. Hence, frequency is the inverse of period.

i.e F = 1/T

2.05Hz = 1/T

T = 1/2.05Hz

T = 0.488 seconds (Rounded to the nearest tenth as 0.5seconds)

Thus, the period of the George Washington Bridge is 0.5 seconds

It requires a force of 100 N to stretch a spring of negligible mass by a distance of 0.1 m. If the spring instead stretches a di
Mariana [72]

by the formula of spring force we know that

F = kx

here we know that

F = 100 N

x = 0.1 m

now we will have

100 = k \times 0.1

k = 1000 N/m

now by similar way if the stretch in spring is 0.25 m

force is given by

F = kx

F = 1000 \times 0.25

F = 250 N

so it will require F = 250 N force

You drive 14.00 km in a straight line in a direction 41° east of north. Find the distance you would have to drive straight east
Anastasy [175]

Answer:

9.1848 km straight east and 10.5659 km straight north

Explanation:

To find these distances, you just have to find the components of this displacement. The inclination in relation to north is 41 degrees, so to find the north component, you need to multiply 14 km by the cossine of 41 degrees, which is 0.7547.

So, the north component is 14 * 0.7547 = 10.5659 km

To find the east component, you multiply 14 by the sine of 41 degrees, which is 0.6561:

14 * 0.6561 = 9.1848 km

You would need to drive 9.1848 km straight east and then 10.5659 km straight north to arrive at the same point.
