Answer:
The particle's velocity is 212.15 m/s.
Explanation:
Given that,
Charge of particle, 
The magnitude of electric field, E = 1270 N/C
The magnitude of magnetic field, B = 1.28 T
Net force, 
We need to find the magnitude of the particle's velocity. the net force acting on the particle is given by Lorentz force as :

So, the particle's velocity is 212.15 m/s.
B = 0.018 T Ans,
Since, it is moving in a circular path, thus, centripetal force will act on it i.e.
F =

where, m is the mass of the object, v is the velocity and r is the radius of circular path.
And, since a positive charge is moving, it will create magnetic force which is equal to F = qvB
where q is the charge, v is the velocity of the particle and B is the magnetic field.
Now, the two forces will be equal,
i.e.

= qvB
⇒

= qB
⇒B =

<span>putting the values, we get,
</span>
use q = 1.6 * 10^ -19
⇒ B = 0.018 T
Answer:
False
Explanation:
The Concentration of Acid or Base is the ph of the solution.
Answer:
w = 1.976 rpm
Explanation:
For simulate the gravity we will use the centripetal aceleration
, so:

where w is the angular aceleration and r the radius.
We know by the question that:
r = 60.5m
= 2.6m/s2
So, Replacing the data, and solving for w, we get:

W = 0.207 rad/s
Finally we change the angular velocity from rad/s to rpm as:
W = 0.207 rad/s = 0.207*60/(2
)= 1.976 rpm
