<span>Momentum equals Mass x Velocity
Mass equals 0.1kg
Velocity equals 5m/s
So the momentum has to = 0.1 x 5 = 0.5kgm/s
I hope this helped

Boiling point and acc motivation
Prior to determining the
experimental design, a scientist typically forms a hypothesis. The answer is
letter B. this is to prepare the scientist, the possible outcome of their
research before the experimental design whether they are wrong or not.
Explanation:
A light bulb changes electrical energy into <em>heat energy and light energy .</em>
To solve this problem we will apply the concepts related to the Doppler Effect, defined as the change in apparent frequency of a wave produced by the relative movement of the source with respect to its observer. Mathematically it can be written as

Here,
= Frequency of the source
= Speed of the sound
= Speed of source
Now the velocity we have that


Then replacing our values,


Therefore the frequency of the observer is 1047.86Hz
