Answer:
1. The speed of infrared radiation is greater than radio wave radiation
2. The wavelength of infrared radiation is less than the radio wave radiation
Explanation:
Given:
The radio wave radiation N₁ is 3x10⁵ to 3x10⁷ Hz and the infrared radiation N₂ is 3x10¹¹ to 3x10¹⁴ Hz. The speed is:
1. The speed of infrared radiation is greater than radio wave radiation
2. The wavelength is:
λ = C/N
where more C, less λ
Then, the wavelength of infrared radiation is less than the radio wave radiation
Answer:
0.182 m/s
Explanation:
m1 = 30,000 kg, m2 = 110,000 kg, u1 = 0.85 m/s
let the velocity of loaded freight car is v
Use the conservation of momentum
m1 x u1 + m2 x 0 = (m1 + m2) x v
30,000 x 0.85 = (30,000 + 110,000) x v
v = 0.182 m/s
Always, whether we notice it or not. It's a law of nature.
The total distance traveled from home to the grocery store would be 8km.
Because both distances she traveled were in the same direction, north, both displacement and distance travel were equal.
If the student traveled in two different directions, such as north to the school and south to the grocery store, her distance traveled would be 8km but her displacement would only be 6km.
The formula for weight is always weight=mass X gravitational field strength.
We already know the mass is 75kg.
The gravitational field strength on the moon is 1.6N. To find out the weight, we can substitute these values in to the formula.
Weight=75 X 1.6
Weight= 120N
Weight is measured on Neutons as it is a force.
