If the particle's velocity were perpendicular to the magnetic field, the magnetic force would be given by:
F = qvB
F is the magnetic force, q is the charge, v is the velocity, and B is the magnetic field strength.
Given values:
F = 0.320N
q = 7.3×10⁻⁶C
v = 4×10⁵m/s
Plug in the values and solve for B:
0.320 = (7.3×10⁻⁶)(4×10⁵)B
B = 0.110T
The magnetic force depends on the cross product between the particle's velocity vector v and the magnetic field vector B. If v and B are parallel then the cross product is 0. v points in the +x direction, therefore B must point in either the +x or -x direction.
Answer:
Explanation:
angular acceleration α = 5 rad /s ²
θ = 1/2 α t² , θ is angle of rotation , t is time .
= .5 x 5 x 4²
= 40 rad .
θ = l / r , θ is angle formed , l is length unwound , r is radius o wheel .
l = θ x r
= 40 x .1
= 4 m .
Answer:
In mitosis, the products are identical to the parent cell, while in meiosis the products are different from the parent cell.
Explanation:
Mitosis replicates DNA at the beginning of the process, so it's always the same, but Meiosis uses a special process called crossing over which causes two chromosomes to swap information, which means that the DNA has changed.
Answer:
- your body moving forwards when sudden brakes/force is applied e.g. sudden braking in a car
- feeling a backwards force when something moves quickly from rest e.g a bus
- when you stir a cup of tea, it continues to swirl for a short period of time even though you have stopped
- when shaking a tree, it's leaves or fruit fall down
- satellites which move due to the inertia of motion
