Answer:
Force acts vertically downward
Explanation:
Solution:-
The force is downward. The field lines point from the north pole to the south pole, or left to right. We will apply the use of right-hand rule. Your fingers point in the direction of the current (away from you). Curl them in the direction of the field (to the right). Your thumb points in the direction of the force(downward).
B. because the heavier an object the stronger the gravitational pull is
Answer:
displacement vector is -16i
Explanation:
Given data:
Displacement relative to entry of tunnel is 20 m
Distance from entry of tunnel at which she notice about camera missing is 6 m
swim distance is 10 m
total distance from entry of tunnel after she swin back is 20+ 6 = 26 m
After covering 10 m to find a camera she will be at 26 -10 = 16 m
If direction out from tunnel is taken as positive then her displacement vector with respect to entry of tunnel is - 16i
where i is unit positive vector.
Answer:
Explanation:
For critical angle C the relation is
SinC = 1 / μ where μ is refractive index of denser medium with respect to rarer medium .
In case of A , refractive index of denser medium with respect to rarer medium .is equal to 1.33 / 1 = 1.33
In case of B , refractive index of denser medium with respect to rarer medium .is equal to 2.42 / 1 = 2.42
In case of C , refractive index of denser medium with respect to rarer medium .is equal to 2.42 / 1.33 = 1.82
In case of D , refractive index of denser medium with respect to rarer medium .is equal to 1.50 / 1.33 = 1.127
In case of D , refractive index is lowest , critical angle will be highest .
In case of B , refractive index of denser medium with respect to rarer medium .is highest so critical angle will be lowest.
Ranking from largest to smallest
D > A >C >B .
The velocity is changing.
