Answer:
mixtures that appear to be the same throughout are homogenous mixtures
Answer:
Explanation:
We can use the following kinematics equation to find the height of the chairlift above the snow:
.
First, let's convert 72 km/h to m/s:
Since the ski starts with an initial vertical velocity of zero, we have . We can now substitute and solve for how high the chairlift is above the snow:
.
Answer:
H=(0,0,2.39)A/m
Explanation:
Ampere's Law for a current filament:
H*(2*pi*R)=I ⇒ H=I/(2*pi*R)
in this case R=y=1; because the current is in the axis x
H=I/(2*pi)=15/(2*pi) A/m=2.39A/m; magnitude
the vector:
to find the direction of the magnetic force H, we uses the right hand rule
H=(0,0,2.39)A/m
I believe the answer is b I’m not sure though
