Determine the minimum number of 120-volt, 20-ampere circuit breakers for a continuous load consisting of 63 feet of track lighting to be installed in a dress shop. Calculate the number of circuits to the larger whole number.

When electric power is transferred over a long distance then, line loss can be reduced by high voltage and low current. Thus, option A is correct.

The complete question is attached to the image below.

The electric circuit transfers the electric current then it is called electric power. The loss in the line over a larger distance is reduced by transferring AC instead of DC voltage.

The AC transmitted is of high voltage, and the power is low. The equation for current is given,

P = VI

The increase in the voltage causes the decrease in the current and in turn the resistance also reduces resulting in the loss of the power of the circuit to decrease.

Therefore, the loss is reduced by transferring high voltage and, low current AC.

In a basketball game, point guard A intends the speed as 47.76 ft/sec, and the launch angle will be 41.084°.

The projectile motion is given as the motion of the object in the curved path near the earth's surface. The throwing of the ball will follow the projectile motion.

The missing image is attached below.

The given game situation consists of:

Velocity of shooting guard (vs) = 12 ft/sec.

Distance from B to C (sc) = 20 ft

Final height to catch the ball, 7 ft

The total distance to cover from B to C = 60 ft

Time is taken to reach B to C = Distance/Speed

Time to reach B to C = 20ft/12ft/sec

Time to reach B to C = 1.667 sec.

The time taken to cover the horizontal distance:

Distance = Velocity * Time

60³ = v₀cosθ * distance/time

60³ =  v₀cosθ * 20/12

v₀cosθ  = 36 ft/sec

The vertical movement can be given where, g = 32.2 ft/sec²:

s = s₀ + v₀sinθ * time + 1/2 -g time²

7 = s + v₀sinθ * 20/12 - 1/2 32.2 ft/sec² * (20/12)²

v₀sinθ = 31.3875 ft/sec

[tex]\rm v_0 =\sqrt{v_0sin\theta^2\;+\;v_ocos\theta^2}[/tex]

Substituting the values:

v₀ = 47.76 ft/sec

The launch angle for the ball will be:

tanθ = v₀sinθ/v₀cosθ

tanθ = 31.3875/36

tanθ = 0.871

θ = 41.084°

Thus, the speed v₀ of the ball will be 47.76 ft/sec, and the launch angle will be 41.084°.

(a) If a kitten weighs 99 grams at birth, it is at 5.72 percentile of the weight distribution.

(b) For a kitten to be at 90th percentile, the minimum weight is 146.45 g.

In a normal distribution curve;

M - 2d = 125 g - 2(15g) = 95 g

M - d = 125 g - 15 g = 110 g

95 g is at 2% and 110 g is at 16%

(16% - 2%) = 14%

(110 - 95) = 15 g

14% / 15g = 0.93%/g

From 95 g to 99 g:

99 g - 95 g  = 4 g

4g x 0.93%/g = 3.72%

99 g will be at:

(2% + 3.72%) = 5.72%

Thus, if a kitten weighs 99 grams at birth, it is at 5.72 percentile of the weight distribution.

M + d = 125 + 15 = 140 g      (at 84%)

M + 2d = 125 + 2(15) = 155 g   ( at 98%)

155 g - 140 g = 15 g

14% / 15g = 0.93%/g

84% + x(0.93%/g) = 90%

84 + 0.93x = 90

0.93x = 6

x = 6.45 g

weight of a kitten in 90th percentile = 140 g + 6.45 g  = 146.45 g

Thus, for a kitten to be at 90th percentile, the approximate weight is 146.45 g
