Answer:
13.12°
Explanation:
Parameters given:
Magnetic field strength, B = 0.350 T
Current in the wire, I = 3.5 A
Force per unit length, F/L = 0.278 N/m
The force on a wire due to the presence of a magnetic field is given as:
F = I*L*B*sinФ
where Ф = angle between the magnetic field and current
The force per unit length, F/L, will be:
F/L = I*B*sinФ
0.278 = 3.5 * 0.35 * sinФ
=> sinФ =
sinФ = 0.227
Ф =
Ф = 13.12°
The angle between the magnetic field and the current is 13.12°.

Firstly, to find speed you need to remember the speed formula:
Speed = Distance ÷ Time
You can do it by doing 2800 ÷ 2 but that gives m/h (metres per hour)
So to convert hours into seconds, you multiply 2 by 7200 (amount of second in 2 hours:
2 * 7200 = 14400 seconds
Now we can do distance ÷ time by plugging the values in:
2800 ÷ 14400 = ≈0.194
<h3>So the average speed is 0.194m/s (metres per second) </h3><h3 /><h2>Hope this helps!</h2>
Answer:
Explanation:
No, not any of these substance will float in Methanol , simply because Methanol has a density of 0.79 g, if you put any substance that weighs more than 0.79 g, it will sink, it all depends on the weight if it is more or less than methanol
2: D=m/v
D=135/50 = 2.7 g/cm³ ( Aluminum)
D=M/V
if two objects has the same mass but one has larger volume, then te one with larger volume has less density
example : 2 objects
mass of both=350
volume of the first one=500 and the other 750
D1=M1/V1 = 350/500 =0.7
D2 = M2/V2 = 350/750 = 0.4666
D1 is larger than D2( with larger volume )
Since there are 3 links in the spring, the angel θ for
equilibrium of the spring is the angle where there are no nte motion of the
spring. It can be easily be solve by jus diving 360 by the number of links.
360/3 = 120 degree is the angle of equilibrium
Answer:
α= 15.4[rad/s^2], 500 [rev/min]
Explanation:
La aceleración angular constante esta definida por la siguiente ecuación:
Para poder llegar a las 2000 [revoluciones /min] estando en 1500 [rev/min], la cuchilla tuvo que incrementar su numero de revoluciones a 500 [rev/min]. Mientras aceleraba.
