Contact is 'touching'. If a person 'touches' something skins cells, sweat and DNA are left behind. This confirms that a person was present.
Answer:
|q1|/|q2| = 1/7
Explanation:
Particle 1 experiences a force F1 due to the magnetic field, B:
F1 = |q1|*v1*B
Particle 2 experiences a force F2 due to the magnetic field, B:
F2 = |q2|*v2*B
We're given that:
v1 = 7v2
Also, the force experience by both particles are equal:
F1 = F2
=> |q1|*v1*B = |q2|*v2*B
|q1|/|q2| = v2/v1
=> |q1|/|q2| = v2/7v2
=> |q1|/|q2| = 1/7
Answer:
1.20Nm
Explanation:
Given data
Force= 53.5N
Perpendicular distance= 2.25cm= 2.25/100= 0.0225m
The expression for the torque is given as
Torque= Force* Perpendicular distance
Torque= 53.5*0.0225
Torque= 1.20Nm
Hence the toque produced is 1.20Nm
