Answer:
0.00225 N/m
Explanation:
Parameters given:
Current in first wire, I(1) = 15A
Current in second wire, I(2) = 15A
Distance between two wires, R = 1cm = 0.01m
The force per unit length between two current carrying wires is:
F/L = μ₀I(1)I(2)/2πR
μ₀ = 4π * 10^(-7) Tm/A
F/L = [4π * 10^(-7) * 15 * 15] / (2π * 0.01)
F/L = 2.25 * 10^(-3) N/m or 0.00225 * 10^(-3) N/m
Answer: True.

You would be able to visualize the basketballs height going up and when it sinks down into the hoop.
A. A control group is given the experimental treatment.
Answer:
(d) 2.93 x 10⁻³ N
Explanation:
Given;
current in the wire, I = 11.4 A
angle of inclination, θ = 11.4⁰
magnetic field on the wire, B = 11. 4 x 10⁻³
length of the wire, L = 11.4 cm = 0.114 m
The magnitude of magnetic force on the wire is given by;
F = BILsinθ
F = (11.4 x 10⁻³)(11.4)(0.114)(sin 11.4°)
F = 0.00293 N
F = 2.93 x 10⁻³ N
Therefore, the correct option is "D"
A) A service winner; the opponent cannot return the serve
B) A tennis stroke made across the body with the back of the hand facing the direction of the stroke
C) Exercising to increase stamina; mostly associated with aerobic activities and cardiovascular health
D) When the ball does not land in the service box
E) Is the absolute range of movement in a joint or series of joints and muscles
F) A stroke done to the right-front of the body (for right-handers), with the racket in a normal position (palm of hand facing opponent)
G) When the service hits the net and lands in a let is played and the server gets another ball
H) A sequence of shots within a point
I) Position facing the net. Used to begin most tennis strokes
J) The way the game begins. Governed by a specific set of rules
K) A tennis stroke that creates a backspin on the ball
L) To exert force on an object using muscles
M) A tennis stroke made across the body with the back of the hand facing the direction of the stroke
