A children's roller coaster is released from the top of a track. If its maximum speed at ground level is 3 m/s, find the height
san4es73 [151]

Answer:

h = 0.46 m

Explanation:

According to the law of conservation of energy:

Potential Energy Lost by Roller Coaster = Kinetic Energy Gained by Roller Coaster

mgh = \frac{1}{2}mv^2\\\\2gh = v^2\\\\h = \frac{v^2}{2g}

where,

h = height = ?

v = speed at bottom = 3 m/s

g = acceleration due to gravity = 9.81 m/s²

Therefore,

h = \frac{(3\ m/s)^2}{(2)(9.81\ m/s^2)}

<u>h = 0.46 m</u>

The erg is a unit of work in units of centimeters (cm), grams (g), and seconds (s), and 1 erg=1 g⋅cm^2/s^2 . Recall that the SI
OverLord2011 [107]

For the given problem, the amount of work done expressed in ergs is 3200 ergs.

Answer: Option A

<u>Explanation: </u>

The work done on an objects are the force acting on it to move the object to a particular distance. So, work done on the object will be directly proportional to the force acting on it and the displacement.

Here, the force acting on the object is given as 0.010 N and the displacement of the object is 0.032 m. So, the work done on the object is

          \text { Work done }=\text { Force } \times \text { displacement }

          \text { Work done }=0.010 \mathrm{N} \times 0.032 \mathrm{m}=0.00032 \mathrm{Nm}

It is known that 1 N=1 \mathrm{kg} \mathrm{ms}^{-2}

So, the work done can be expressed in k g m s^{-2} as,

         \text { Work done }=0.00032 \mathrm{kgm}^{2} \mathrm{s}^{-2}

It is known that 1 \mathrm{erg}=1 \mathrm{g} \mathrm{cm}^{2} / \mathrm{s}^{2}, so the conversion of units from Nm to erg will be done as follows:

\text { Work done }=0.00032 \mathrm{kgm}^{2} \mathrm{s}^{-2} \times \frac{1000 \mathrm{g}}{1 \mathrm{kg}} \times \frac{100 * 100 \mathrm{cm}^{2}}{m^{2}}=3200 \mathrm{g} \mathrm{cm}^{2} \mathrm{s}^{-2}

Thus, work done in ergs is 3200 ergs.

A student sees a newspaper ad for an apartment that has 1730 square feet (ft2) of floor space. How many square meters of area ar
SVETLANKA909090 [29]

The correct answer for this question is 160.89 m².

The square footage of a newspaper ad for an apartment is = 1730ft²

We know that one square foot equals 0.093 square meters.

We can determine the area in square meters using the above conversion.

Total square meters = 0.093×1730ft² (or) 1730÷10.7 

                                    = 160.89 m²

If the angle of incidence of light falling on a plane mirror is 30°, what will be the angle of reflection?.
nekit [7.7K]

The angle of reflection made when the angle of incidence of light falling on a plane mirror is 30 degrees is 30 degrees (made with a surface normal to the mirror surface.) The reflected ray will make an angle of (90- 30=) 60 degrees with the mirror surface.

It is referred to as light reflection when a light ray hits a polished or smooth surface and bounces back. The incident light rays hit the surface and are reflected off of it. The beam that returns is referred to as the reflected ray.

The angle of reflection and the angle of incidence, are the angles formed by these light rays when they reflect back or fall on a surface, respectively.
