Answer:
a) 
V.m , into the page
b) 
V, counterclockwise
Explanation:
a) 
At t = 2.90, I = 3.62 + 1.49 * (2.90)^2 = 16.15 A
V.m
Direction is into the page.
b) 
Direction is counterclockwise.
Answer:
Microwaves, like other forms of electromagnetic radiation, can propagate through space (i.e. they don't require a medium like air or water to travel through).
Explanation:
<span>The initial momentum is 5 kg m/s and the final momentum is 10 kg m/s
'cause P = m*v, when we increase either m or v, P also increases by the same expression,
P = 5 * 2 = 10
So, option D is your answer!!
Hope this helps!

Answer:
11.8 m/s
Explanation:
At the top of the hill, there are two forces on the car: weight force pulling down (towards the center of the circle), and normal force pushing up (away from the center of the circle).
Sum of forces in the centripetal direction:
∑F = ma
mg − N = m v²/r
At the maximum speed, the normal force is 0.
mg = m v²/r
g = v²/r
v = √(gr)
v = √(9.8 m/s² × 14.2 m)
v = 11.8 m/s
Answer:
Inward
Explanation:
As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle. This would mean that the force is always directed perpendicular to the direction that the object is being displaced. hope this helps :)
