I feel like it’s Boyle’s Law, correct me if I’m wrong .
Answer:
Manuel function can be used when we move it. Oscillate function automatically moves on its own. The pulse function mimics the pulse of a heart rate and can only be used by pushing the button.

<u>Answer:</u> The average kinetic energy of helium atoms is 
<u>Explanation:</u>
To calculate the average kinetic energy of the atom, we use the equation:
where,
K = average kinetic energy = ?
k = Boltzmann constant = 
T = temperature = 
Putting values in above equation, we get:
Hence, the average kinetic energy of helium atoms is
1.41 × 10³⁰ MeV
As we know, E=mc², where E is energy, m is mass and c is the speed of light(i.e. 3×10⁸ m/s).
Given mass = 2.5 kgs
∴ E = (2.5)×(3×10⁸)² J = 22.5×10¹⁶ J
As our answer is in joules so we have to convert it into mega electron volt(MeV)
1 J = 6.242 × 10¹² MeV
⇒ 22.5×10¹⁶ J = 22.5×10¹⁶ × (6.242 × 10¹²) MeV
⇒1.41 × 10³⁰ MeV

The displacement is the distance from the beginning point to the ending point. The time was just to throw you off. If he walks 30m due west, and then 5m due east, his displacement would be 30-5=25m to the west.
