They require that they be a closed circuit, the current must find its way from the power source through the resistance and back again.<span />

An engineer wishes to design a roller coaster so that
nataly862011 [7]

To prevent cars from falling, the radius at the top of the circle should be

small such cars inverted at the top remain attached during motion.

Correct response;

The radius of the coaster can be <u>C) 20 m</u>

<h3>Method by which the above option is selected</h3>

Mass of roller coaster car, m = 500 kg

Speed at the top of the circle, v = 20 m/s

Required:

The maximum radius of the circular path the roller coaster car.

Solution:

\displaystyle Centrifugal \ force, \, F_{c} = \mathbf{\frac{m \cdot v^2}{r}}

Where;

r = The radius of the circular path.

Weight of the roller coaster car = m·g = The centripetal force

Where;

g = Acceleration due to gravity = 9.81 m/s²

At equilibrium, we have;

Centrifugal force = Centripetal force

\displaystyle \frac{m \cdot v^2}{r}  = \mathbf{ m \cdot g}

Therefore;

\displaystyle r = \mathbf{ \frac{v^2}{g}}

Which gives;

\displaystyle r = \frac{20^2}{9.81} \approx 40.77

The maximum radius for safety of a roller coaster, r ≈ 40.77 meters

\displaystyle Range \ of \ radius \ of \ the \ circle = \frac{40.77}{4}  \leq Radius \ of \ circle \leq 40.77

Which gives;

Range of the radius of the circle = 10.2 ≤ Radius of circle ≤ 40.77

The correct option for safety considerations is therefore;

  • <u>C) 20 m</u>

<em>The possible question options are;</em>

<em>A) 5 m  B) 10 m  C) 20 m  D) 40 m  E) 80 m</em>

Answer:

6.7 × 10^{-2}

Explanation:

Initial P = Final P

(1.8 × 0) + (.0075 × 0) = (1.8 × x) + (.0075 × 16)

-.12 + 1.8x

x = .0067

A cat runs and jumps from one roof top to another which is 5 m away and 3 m below. Calculate the minimum horizontal speed with w
icang [17]
ThIs is the same type of problem
find out the time value
3 = 1/2*a*T^2
6/10 = t^2
t = 0.77 seconds
and the distance is given 5 m
thus speed ,= distance/time
speed = 5/0.77
= 6.45 m/s

Explain how the potential energy of two charged particles depends on the distance between the charged particles and on the magni
maks197457 [2]

Answer:

According to Coulomb's Law, the potential energy of two charged particles is directly proportional to the product of the two charges and inversely proportional to the distance between the charges

Explanation:

According to Coulomb's Law, the potential energy of two charged particles is directly proportional to the product of the two charges and inversely proportional to the distance between the charges.  Since the potential energy  of two charged particles is directly proportional to the product of the two charges, its magnitude increases as the charges of the particles increases. For like charges, the potential energy is positive(the product of the two alike charges must be positive) and since potential energy is inversely proportional to the distance between the charges therefore it decreases as the particles get farther apart . For opposite charges, the potential energy is negative(the product of the two opposite charges must be negative) and since potential energy is inversely proportional to the distance between the two charges, it becomes more negative as the particles get closer together.
