Radar detectors use radio waves to measure the speed of moving

Chemistry
1 answer:
bagirrra123 [75]2 years ago
6 0

Answer:

1.7x10^8 Hz

Explanation:

Frequency could be explained as the number of occurrences of a repeating event at a time

Given:

wavelength = 1.8 meters

The frequency f of the waves can be calculated using f = c / λ

Where c (m/s) is the speed of the wave

λ (m) is the wavelength

Speed c= 3*10^8 m/s

Frequency f= 3*10^8 /1.8

Frequency= 1.7x10^8 Hz

Therefore,the frequency of waves from a radar detector is 1.7x10^8 Hz

Calculate the volume of the gas, in liters, if 1.35 mol
Alina [70]

Answer:

22.8 L

Explanation:

Step 1: Given data

  • Moles of the gas (n): 1.35 mol
  • Pressure of the gas (P): 1.30 atm
  • Temperature (T): -6°C
  • Ideal gas constant (R): 0.0821 atm.L/mol.K

Step 2: Convert "T" to Kelvin

We will use the following expression.

K = °C + 273.15 = -6 + 273.15 = 267 K

Step 3: Calculate the volume of the gas

We will use the ideal gas equation.

P × V = n × R × T

V = n × R × T / P

V = 1.35 mol × (0.0821 atm.L/mol.K) × 267 K / 1.30 atm

V = 22.8 L

If you change your workout from a
Westkost [7]
Answer:

HIIT workouts are anaerobic, and cardiovascular endurance workouts are usually aerobic, depending on how much you work out. If you changed speed and switched to a different workout immediately after what you did before, your heart rate would increase, and you would experience pain on the side of your abdominal. It can be because your body isn’t used to the change in speed and endurance.

What is the measurement 1042 L rounded off to two signicant digits ?
SOVA2 [1]
This is a really hard question. Because if you change it to 1,000 then that's only one. If you add the decimal so it's 1,000. , then that's 4 if you change it to 1,040, that's 3. So you can not change that to 2 significant digits.

nadya68 [22]

Answer:

photosynthesis

Explanation:

The process by which land plants produce their own food using sunlight and carbon dioxide is known as photosynthesis (Figure 1). While carbon dioxide is absorbed by the leaves, the sunlight is captured by a chemical molecule in the plant, called chlorophyll (Chl).
