A roller coaster moves 200 ft horizontally, then rises 135 ft at an angle of 30.0° above the horizontal. Next, it travels 135 f

t at an angle of 40.0° below the horizontal. Use graphical techniques to find the roller coaster's displacement from its starting point at the end of this movement.

Answer:

171 ft

Explanation:

The distance to be calculated is AB

AB = AC + BC

AC;  Cos 60 = AC ÷ 135

AC = 135 cos 60 = 67.5 ft

BC; Cos 40 = BC ÷ 135

BC = 135 cos 40 = 103.416 ft

AB = 67.5 + 103.416 = 170.9159998210 ft

Distance between starting point to end point = 171 ft

How much equal charge should be placed on the earth and the moon so that the electrical repulsion balances the gravitational for
kumpel [21]

As we know that electrostatic force between two charges is given as

F = \frac{kq_1q_2}{r^2}

here we know that electrostatic repulsion force is balanced by the gravitational force between them

so here force of attraction due to gravitation is given as

F_g = 1.98 \times 10^{20} N

here we can assume that both will have equal charge of magnitude "q"

now we have

1.98 \times 10^{20} = \frac{kq^2}{r^2}

1.98 \times 10^{20} = \frac{(9\times 10^9)(q^2)}{(3.84 \times 10^8)^2}

1.98 \times 10^{20} = (6.10 \times 10^{-8}) q^2

now we have

q = 5.7 \times 10^{13} C

A nuclear fission power plant has an actual efficiency of 32%. If 0.18 MW of power are produced by the nuclear fission, how much
7nadin3 [17]

Answer:

 P₀ = 5.76 x 10⁻² MW

Explanation:

given,

efficiency of the power plant = 32%

Power produced by the nuclear fission = 0.18 MW

the power plant output = ?

using formula of efficiency

\eta = \dfrac{P_0}{P}

where P is the power produced in the power plant

          P₀ is the power output of the power plant

\eta = \dfrac{P_0}{P}

0.32 = \dfrac{P_0}{0.18}

 P₀ = 0.18 x 0.32

 P₀ =  0.0576 MW

 P₀ = 5.76 x 10⁻² MW

Power plant output is equal to  P₀ = 5.76 x 10⁻² MW

Type the correct answer in the box. Spell all words correctly.
Fantom [35]

Rodney is working to identify a perpetrator. He knows that his friend, Jude, believes the victim's spouse is guilty. Hence, Rodney should avoid  having unconscious bias.

Explanation:

The immediate context here is that, Rodney is in search of a perpetrator. He had beliefs on Jude, i.e. his friend. Jude further believes and knows about who the real culprit it. So there is no point for Rodney to undertake bias. He should avoid bias.  The right context suggests that the victim is Innocent, but his spouse is the real culprit.

Rodney kind needs to consider this. To talk of formal terms, bias can be unconscious bias, or conformity bias etc. Before taking any discussion, we should think over everything. and we should avoid unconscious bias". Rodney should avoid unconscious bias.
