You are watching: Which ocean has the greatest average depth?
hunterriverpei.com: 9.59° and also 350.41°
Explanation: The formulae that relates the pressure F exerted ~ above a moving charge q with velocity v in a magnetic field of toughness B is offered as
F =qvB sin x
Where x is the angle in between the stamin of magnetic field and velocity that the charge.
q = 1.609×10^-19 C
v = 4×10³ m/s
B = 1.25 T
F = 1.40×10^-16 N
By substituting the parameters, we have that
1.40×10^-16 = 1.609×10^-19 × 4×10³ × 1.25 × sinx
sin x = 1.40×10^-16/ 1.609×10^-19 × 4×10³ × 1.25
sin x = 1.40×10^-16 /8.045*10^(-16)
sin x = 0.1666
x = 9.59°
The worth of sin x is confident in very first and 4th quadrant.
Hence to obtain the second value of x, we move to the fourth quadrant of the trigonometric quadrant i beg your pardon is 360 - x
Hence = 360 - 9.59 = 350.41°

12) go the brand “centripetal force” ever show up in an FBD?
\"Though a force, or a resulting sum of forces, may be centripetal, over there is no an really \"Centripetal Force\" that would show up on an FBD. Because an FBD is a diagram of physical pressures at work upon a body, and also a centripetal force is not the reaction of part physical object upon another, it would not be suitable to display it. You can have a tension force, a load force, a normal force, electric forces, magnetic forces, or any number of reactions, however actually labeling any kind of of them \"centripetal\" would be unconventional\".-hunterriverpei.comhoo

If a glass is knocked turn off of a table that is 1.4m tall, just how long does the take because that the glass to hit the ground?
H = 1.4 m, the elevation the glass falls.u = 0, initial upright velocity, since the glass is knocked off a table.Assume g = 9.8 m/s², and also ignore wait resistance.Let t = the moment for the glass to hit the ground.Then(1/2)*(9.8 m/s²)*(t s)² = (1.4 m)4.9t² = 1.4t² = 0.2857t = 0.5345 shunterriverpei.com: 0.54 s (nearest hundredth)

Consider a particle with early velocity v⃗ that has actually magnitude 12.0 m/s and is directed 60.0 degrees above the an unfavorable x axis.
-6.0 m/s, 10.4 m/s
To discover the x- and also y- components, we have actually to apply the formulas:
v = 12.0 m/s is the size of the vector
Here, the angle given is the angle above the an adverse x-axis; this method that the angle with respect come the confident x-axis is
So, the two materials are:

A planet has two moons. The very first moon has an orbital period of 1.262 planet days and an orbital radius of 2.346 x 104 km. The se
Kepler\"s third law hypothesizes that for all the tiny bodies in orbit about the same main body, the ratio of (orbital period squared) / (orbital radius cubed) is the same number.
