Answer:
decreases, but frequency increases.
Explanation:
Wavelength and frequency are inversely proportional, meaning the higher the frequency, the shorter the wavelength, and the lower the frequency, the longer the wavelength.
The answer is Element.
Because they are found on the periodic table and they are represented by symbols.
Example: Oxygen; its symbol is O. And it is found in group 16 on the periodic table.
Answer:
To find the distance, use the formula for distance d = st, or distance equals speed times time.
Answer:
The astronaut will be propelled towards the shuttle at the rate of 0.4 m/s.
Explanation:
Given;
mass of the astronaut, m₁ = 95 kg
mass of the hammer thrown, m₂ = 2 kg
velocity of the hammer, v₂ = 19 m/s
let the recoil velocity of the shuttle = v₁
Apply the principle of conservation of linear momentum;
m₁v₁ = m₂v₂
v₁ = m₂v₂/m₁
v₁ = (2 x 19) / 95
v₁ = 0.4 m/s
Therefore, the astronaut will be propelled towards the shuttle at the rate of 0.4 m/s.
