Explanation:
Assuming constant density, the pressure at a depth h is:
P = Patm + ρgh
3 (1.013×10⁵ Pa) = 1.013×10⁵ Pa + (1025 kg/m³) (9.81 m/s²) h
h = 20.1 m
Two things that aren't involved in speed: -- the straight-line distance between the start- and end- points. -- the direction from start-point to end-point.
The proton will be moving if it is to follow a circular path with radius 2cm in magnetic field of 0.7T is 1.34 x 10⁷ m/s.
<h3>What is magnetic field?</h3>
It is the region of space where a charge experiences the magnetic force when it enters the field.
While moving in the circular path, centripetal force is equal to the magnetic force.
Fm = Fc
q x v x B = m x v² / r
v= qBr /m
where mass of proton m =1.67262 × 10−27 kg, charge of proton q =1.6 x 10⁻¹⁹ C and magnetic field B =0.7T.
Then, velocity is
v = 1.6 x 10⁻¹⁹ x 0.7 x 0.02 / 1.67262 × 10⁻²⁷
v = 1.34 x 10⁷ m/s.
Thus, the proton will be moving if it is to follow a circular path with radius 2cm in magnetic field of 0.7T is 1.34 x 10⁷ m/s.

Hope this helps
If u hit oobleck hard it is a solid and when you pick it up and let it fall of your hand it turns into a liquid
