You could be lying completley still on your bed, and all though it seems you are at rest, you are moving along with the earth around the sun and hence are motion. This is why 'being at rest' is more of a relative term. Hope this helps!
<span>speed = wavelength x frequency
speed = 0.4m X 10 Hz
speed = 4 m/s</span>
Answer:
noble gases are basically a group of gases that are similar in their chemical compounds, theres six of them : helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).

Answer:
Speed of another player, v₂ = 1.47 m/s
Explanation:
It is given that,
Mass of football player, m₁ = 88 kg
Speed of player, v₁ = 2 m/s
Mass of player of opposing team, m₂ = 120 kg
The players stick together and are at rest after the collision. It shows an example of inelastic collision. Using the conservation of linear momentum as :

V is the final velocity after collision. Here, V = 0 as both players comes to rest after collision.



So, the speed of another player is 1.47 m/s. Hence, this is the required solution.
Answer:
Explanation:
This question is regarding gravity under motion. Then we can use motion equation to find the final velocity .
Inertial velocity is zero when it's release from rest.
V = U+at
V = 0+ 9.8×3.63
V = 35.574 m/s
