Answer:
B = 5.59x10⁹ T
Explanation:
The magnetic force (F), on a the alpha particle with charge (q) that is moving at velocity (v) as the cross product of the velocity and magnetic field (B) is:
<u>We have:</u>
F = 1.4x10⁻³ N
v = 2.6x10⁶ m/s
θ = 37.0°
q = 2*p = 2*1.6x10⁻¹⁹ C
Hence, the strength of the magnetic field is:
Therefore, the strength of the magnetic field is 5.59x10⁹ T.

Obesity is primarily caused by a lack of physical activity or by unhealthy dietary habits. The positive energy balance underlying obesity is generally attributed to chronic excess energy intake or reduced physical activity.
A scalar quantity is one in which there is no direction given.
30 Lbs would be the answer, since there is no indicator of direction.
The work done by the rope on the box is equal to:
where F is the force applied by the rope, d the distance covered by the box and
is the angle between the direction of the force and of the displacement.
Using the data of the problem:
,
and
, we find the work:
