77julia77 [94]

Answer:

air mass

Explanation:

These are known as the air mass. However, the air mass results in sever storms at times. The storms are known as tornadoes. The storms are also very powerful as they can cause the distraction of everything in their path.In addition, the large sections result in the different types of air masses. These air masses are known as:

  • polar
  • tropical
  • continental and
  • maritime.

Using your knowledge of momentum explain why cars are designed to have crumple zones?
Molodets [167]

Answer: I think cars are designed to have crumble zone because lets say you're going 60-70 mph and you hit a brick wall that cant move, it would be a very hard jolt causing the beings inside to get thrown forward, but if it has a crumble zone it would slow the the jolt from is slowing down in the hit.

A wave has a wavelength of 4. 9 m and a velocity of 9. 8 m/s. The medium through which this wave is traveling is then heated so
tatiyna

The wavelength of a wave is obtained by taking the ratio of wave speed and frequency.

The wavelength of the heated wave is 9.8 m. Hence, option (b) is correct.

What is frequency of a wave?

The number of oscillations completed by a wave in one second is known as the frequency of a wave. It is expressed as the ratio of the velocity of the wave to its wavelength.

Given data-

The wavelength of the wave is, \lambda = 4.9 \;\rm m.

The velocity of the wave is, v = 9.8 m/s.

The mathematical expression for the frequency of the wave is,

f = \dfrac{v}{\lambda}

Solving as,

f = \dfrac{9.9}{4.9}\\\\f =2 \;\rm Hz

Now, with constant frequency and the double magnitude of velocity (v' = 2 × 9.8 = 19.6 m/s). The wavelength of the heated wave is calculated as,

f = \dfrac{v'}{\lambda'}

here,

\lambda' is the wavelength of the heated wave.

Solving as,

2 = \dfrac{19.6}{\lambda'}\\\\\lambda' = \dfrac{19.6}{2}\\\\\lambda' = 9.8 \;\rm m

Thus, we can conclude that the wavelength of the heated wave is 9.8 m. Hence, option (b) is correct.

The radar system of a navy cruiser transmits at a wavelength of 1.4 cm, from a circular antenna with a diameter of 2.7 m. At a r
Goshia [24]

Answer:

Distance will be 49.34 m

Explanation:

We have given wavelength \lambda =1.4cm =0.014m

Diameter of the antenna d = 2.7 m

Range L = 7.8 km = 7800 m

We have to find the smallest distance hat two speedboats can be from each other and still be resolved as two separate objects D

We know that distance is given by D=\frac{L1.22\lambda }{d}=\frac{7800\times 1.22\times 0.014}{2.7}=49.3422m

So distance D will be 49.34 m
