islas change in velocity is 30 m/s, and hazel has the same change in velocity. which best describes explains why they would have
2 answers:
Explanation:
Acceleration is defined as change in velocity with respect to change in time.
Mathematically, Acceleration = \frac{\Delta v}{\Delta t}[/tex]
where = change in velocity
= change in time
When Islas and Hazel both has change in velocity as 30 m/s but still their acceleration is different then it means that change in time for both of them is different.
Thus, they have different acceleration.

Answer:
B = 4.1*10^-3 T = 4.1mT
Explanation:
In order to calculate the strength of the magnetic field, you use the following formula for the magnetic flux trough a surface:
(1)
ФB: magnetic flux trough the circular surface = 6.80*10^-5 T.m^2
S: surface area of the circular plate = π.r^2
r: radius of the circular plate = 8.50cm = 0.085m
B: magnitude of the magnetic field = ?
α: angle between the direction of the magnetic field and the normal to the surface area of the circular plate = 43.0°
You solve the equation (1) for B, and replace the values of the other parameters:
The strength of the magntetic field is 4.1mT
