Answer:
The magnetic field strength required to hold anti-protons, moving at 5.70 ✕ 10⁷ m/s in a circular path of 3.20 m in radius is 0.186 T.
Explanation:
To solve the question we note that the magnetic force on a moving charge is given by
F = q·v·B
Where
q = Charge
v = Velocity of the charge =5.70 ✕ 10⁷ m/s
B = Magnetic field
Based on Newton's second law,
Force = Mass, m × Acceleration, a = m × a
Where:
a = Acceleration
m = Mass of anti-proton = Mass of proton = 1.6726219 × 10⁻²⁷ kg
We note that for circular motion, acceleration a is given by
.
Where:
r = Radius = 3.20 m
Therefore, for the circular motion, force, F =
Equating the magnetic force equation to the circular force equation, we have
= q·v·B So that, we find B by making the subject of the formula as follows
. Which gives
= 0.186 T
The magnetic field strength is
B = 0.186 T
Answer:
<em>The magnitude of the pulling force is 20.66% of the gravitational force acting on the box</em>
Explanation:
<u>Accelerated Motion</u>
The net force exerted on a body is the (vector) sum of all forces applied to the body. The net force can be decomposed in its rectangular components and the dynamics of the body can be studied in each direction x,y separately.
Let's start off by calculating the acceleration the worker gives to the box when pulling it. The distance traveled by the box initially at rest in a time t at an acceleration a is given by
Solving for a
Now we analyze the geometric of the forces applied to the box. Please refer to the free body diagram provided below.
The forces in the y-axis must be in equilibrium since no movement takes place there, thus, being g the acceleration of gravity:
There Ty is the vertical component of the tension of the rope, N is the normal force, and m is the mass of the box
The decomposition of T gives us
Solving the above equation for N
Now for the x-axis, there are two forces acting on the box, the x-component of the tension and the friction force Fr. Those forces are not equilibrated, thus acceleration is produced:
Recalling that
Replacing N from [1]
Operating
Solving for T
We don't know the value of m, thus we'll plug in the rest of the data
Dividing by the weight of the box m.g
Thus, the magnitude of the pulling force is 20.66% of the gravitational force acting on the box
<em>Mass of fuel has the airplane took on = 167.89 kg</em>
Density is a quantity derived from the mass and volume
density is the ratio of mass per unit volume
With the same mass, the volume of objects that have a high density will be smaller than objects with a smaller type of mass
The unit of density can be expressed in g / cm3 or kg / m3
- Density formula:
ρ = density
m = mass
v = volume
A common example is the water density of 1 gr / cm3
If we look at fuel capacity data such as Airbus which has a maximum capacity of 204, 5 liters then the mass of fuel it carries is
ρ = 0.821 gr / ml = 0.821 kg / l
- mass = ρ . V
mass = 0.821 kg / l . 204.5 liters
mass = 167.89 kg
So the mass of fuel carried by aircraft is 167.89 kg
