Answer:
"Low pressure system"
Explanation:
The area you are describing is known as a "low-pressure system" in meteorology. In a low-pressure system, the atmospheric pressure at the surface is lower than the pressure in the surrounding areas. This difference in pressure causes air from the surrounding areas to flow into the low-pressure region, creating a circulation pattern. As the air rises within the low-pressure system, it cools and can lead to the formation of clouds and precipitation. Low-pressure systems are often associated with stormy weather and can bring rain, snow, or other forms of precipitation, depending on the temperature and moisture content of the air.
Answer:
15.7m/s
Explanation:
To solve this problem, we use the right motion equation.
Here, we have been given the height through which the ball drops;
Height of drop = 14.5m - 1.9m = 12.6m
The right motion equation is;
V² = U² + 2gh
V is the final velocity
U is the initial velocity = 0
g is the acceleration due to gravity = 9.8m/s²
h is the height
Now insert the parameters and solve;
V² = 0² + 2 x 9.8 x 12.6
V² = 246.96
V = √246.96 = 15.7m/s
Answer:
Glacial Striations
Explanation:
Glacier is an erosion agent that transports and deposits sediments.
Due to the weight and gradual flow of a glacier, it carves along parts of the mass beneath it, these parts are known as sediments, this movement causes marks to appear on the land beneath it. These marks are called Glacial Striations.
b. fresh water
c. air
d. cast iron
2. A wave has a wavelength of 10 mm and a frequency of 5 hertz. What is its speed?
a. 50 mm/s
b. 50 hertz/s
c. 2 mm/s
d. 0.50 mm/s
3. How does reflection differ from refraction and diffraction?
a. Reflection is the only process in which the wave does not continue moving forward.
b. Reflection is the only process that involves a change in the wave.
c. Reflection affects all types of mechanical waves, but refraction and diffraction do not.
Answer : 1. cast iron
2. 50 mm/s
3. Reflection is the only process in which the wave does not continue moving forward.
Explanation :
1. The speed of sound is greatest in solid. So, the speed of the sound is fastest in cast iron. It is approximately equal to 4600 m/s.
2. Wavelength, λ = 10 mm
Frequency, υ = 5 Hz
Speed = wavelength × frequency
Speed = 10 mm × 5 s⁻¹
Speed, s = 50 mm/s
3. The bouncing back of light is called the reflection of light. In this process, the wave does not continue moving forward.
1- CAST IRON
2- 50 mm/s
3- Reflection is the only process in which the wave does not continue moving forward.
B. The farthest point in the Moon's orbit to Earth
C. The closest point in Earth's orbit of the Sun
D. The Sun's orbit that is closest to the Moon
Answer:
A. The closest point in the Moon's orbit to Earth
Explanation:
The perigee is defined as the closest point in the orbit of an object (such as a satellite) from the centre of the Earth. In this case, the Earth's satellite is the Moon, so the perigee is defined as the closest point in the Moon's orbit to Earth. so option A is the correct one.
Let's see instead the names of the other options:
B. The farthest point in the Moon's orbit to Earth --> this point is called apogee
C. The closest point in Earth's orbit of the Sun --> this point is called perihelion
D. The Sun's orbit that is closest to the Moon --> this point has no specific name
