I got you gurl so if your looking for speed kts speed =distance +time and when you do all your steps correctly its speed=320 m/s....... Hope this helped
Given that,
Current = 4 A
Sides of triangle = 50.0 cm, 120 cm and 130 cm
Magnetic field = 75.0 mT
Distance = 130 cm
We need to calculate the angle α
Using cosine law




We need to calculate the angle β
Using cosine law




We need to calculate the force on 130 cm side
Using formula of force



We need to calculate the force on 120 cm side
Using formula of force


The direction of force is out of page.
We need to calculate the force on 50 cm side
Using formula of force


The direction of force is into page.
Hence, The magnitude of the magnetic force on each of the three sides of the loop are 0 N, 0.1385 N and 0.1385 N.
Answer:
v=v0 - gt
Explanation:
The equation for velocity is
v=v0 - gt
where v0=14m/s, g=10m/s^2.
in 1 second:
v=14-10=4m/s
it is positive so direction is upwards
in 2 seconds:
v=14-20=-6m/s
it is negative so direction is downwards
Answer:
The units (km/h) tell you how to do this! 200km/3h = 66.66666666…. BUT technically you only have ONE significant digit: 3 so 66.666… rounded to ONE digit is 70km/h but that is probably not important in this intro class so V = 66.67 or 67 km/h
