Magnetic torquer
or torque rod are essentially sets of electromagnets that are laid out to create a
magnetic field that interfaces with an ambient magnetic field, so that the
counter-forces produced is a stronger magnetic force. In addition, its magnetic
field strength increases with the current due to the rod that has field lines
pointing in the same direction, closed together and nearly parallel with uniformly
spaced. This set up indicates that the field of a torque rod produced powerful
magnetic field than a torque coil.
Answer:
0.04225 Nm
Explanation:
N = Force applied = 5 N
= Coefficient of static friction = 0.65
d = Diameter of knob = 1.3 cm
r = Radius of knob =
Force is given by
When we multiply force and radius we get torque
Torque on thumb
Torque on forefinger
The total torque is given by
The most torque that exerted on the knob is 0.04225 Nm
Net force is 5000 - 1000 = 4000 N
F = ma
4000 = 200a
a = 20 m/s^2
Answer:
the direction of acceleration of the vehicle is the same direction of its velocity of car
s acceleration has the opposite direction to the car speed.
Explanation:
The initial acceleration of the car can be calculated with
v = v₀ + a t
a = (v-v₀) t
indicate that the initial velocity is zero (v₀ = 0 m / s)
a = v / t
a = 300 / t
the direction of acceleration of the vehicle is the same direction of its acceleration movement.
When the car collides with the wall, it exerts a force in the opposite direction that stops the vehicle, therefore this acceleration has the opposite direction to the car speed. But your module must be much larger since the distance traveled to stop is small
