Which of these labels can be used for speed. Hint: There are 3.

Answer:

An excess of positive (or negative) charge causes the leaves to diverge

Bringing a neutral rod in the vicinity of the electroscope will cause some of the positive charge to leave the leaves (making the electrically neutral rod negative at the tip) causing the leaves to converge.

Answer:

11.3 g/cm^3

Explanation:

density = mass/volume

volume of rectangular prism = length * width * height

volume = (4.50 cm)(5.20 cm)(6.00 cm) = 140.4 cm^3

mass = 1587 g

density = (1587 g)/(140.4 cm^3)

density = 11.3 g/cm^3

I'll do coal. and maybe a little more.

Explanation:

Coal What is it?

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen.

Coal How we obtain it:

Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.

Coal Pros:

Coal is plentiful in many places and it is easy to access through mining, so people rely on it to produce energy. Coal is easy to store. Once it is mined it can be safely stored with no hazard of fire or explosion like there is with gas or oil. It is relatively easy and inexpensive to convert coal into energy.

Coal Cons:

Coal is nonrenewable.  Coal contains the most CO2 per BTU, the largest contributor to global warming.  Severe environmental, social, and health, and safety impacts of coal mining.  The devastation of the environment around coal mines is heavy.  High cost of transporting coal to centralized power plants. Coal is really dirty and not good.

Solar What is it?

Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.

Solar How we obtain it:

Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage.

Solar Pros:

It's clean energy. Solar power is pollution-free and causes no greenhouse gases to be emitted after installation.  It has reduced dependence on foreign oil and fossil fuels.  It is renewable clean power that is available every day of the year, even cloudy days produce some power.  It gives a return on investment unlike paying for utility bills.

Solar Cons:

Solar doesn't work at night. Solar panels are not attractive. You can't install a home solar system yourself. My roof isn't right for solar. Solar hurts the environment. Not all solar panels are high quality.

Answer:

Approximately [tex]10\; \rm m \cdot s^{-1}[/tex] at [tex]5.6^\circ[/tex] below the horizon.

(Assumption: air resistance on the ball is negligible; [tex]g = 9.81\; \rm m \cdot s^{-2}[/tex].)

Explanation:

Assume that the air resistance on the ball is negligible. The horizontal component of the velocity of the ball would stay the same at [tex]10\; \rm m \cdot s^{-1}[/tex] until the ball reaches the ground.

On the other hand, the vertical component of the ball would increase (downwards) at a rate of [tex]g = 9.81\; \rm m\cdot s^{-2}[/tex] (where [tex]g[/tex] is the acceleration due to gravity.) In [tex]0.1\; \rm s[/tex], the vertical component of the velocity of this ball would have increased by [tex]9.81\; \rm m \cdot s^{-2} \times 0.10\; \rm s = 0.981\; \rm m \cdot s^{-1}[/tex].

However, right after the ball rolled off the edge of the table, the vertical component of the velocity of this ball was [tex]0\; \rm m\cdot s^{-1}[/tex]. Hence, [tex]0.10\; \rm s[/tex] after the ball rolled off the table, the vertical component of the velocity of this ball would be [tex]0\; \rm m \cdot s^{-1} + 0.981\; \rm m\cdot s^{-1} = 0.981\; \rm m \cdot s^{-1}[/tex].

Calculate the magnitude of the velocity of this ball. Let [tex]v_{x}[/tex] and [tex]v_{y}[/tex] and denote the horizontal and vertical component of the velocity of this ball, respectively. The magnitude of the velocity of this ball would be [tex]\displaystyle \sqrt{{v_x}^{2} + {v_y}^{2}}[/tex].

At [tex]0.10\; \rm s[/tex] after the ball rolled off the table, [tex]v_x = 10\; \rm m \cdot s^{-1}[/tex] while [tex]v_y = 0.981\; \rm m \cdot s^{-1}[/tex]. Calculate the magnitude of the velocity of the ball at this moment:

[tex]\begin{aligned} \| v \| &= \sqrt{{v_x}^{2} + {v_y}^{2}} \\ &= \sqrt{\left(10\; \rm m \cdot s^{-1}\right)^{2} + \left(0.981\; \rm m \cdot s^{-1}\right)^{2}} \\ &\approx 10.0\; \rm m\cdot s^{-1}\end{aligned}[/tex].

Calculate the angle between the horizon and the velocity of the ball (a vector) at that moment. Let [tex]\theta[/tex] denote that angle.

[tex]\displaystyle \tan \theta = \frac{\text{rise}}{\text{run}}[/tex].

For the vector representing the velocity of this ball:

[tex]\displaystyle \tan \theta = \frac{0.981\; \rm m \cdot s^{-1}}{10\; \rm m \cdot s^{-1}} = 0.0981[/tex].

Calculate the size of this angle:

[tex]\theta = \arctan 0.0981 \approx 5.62^\circ[/tex].

Notice that the vertical component of the velocity of this ball at that moment points downwards (towards the ground.) Hence, the corresponding velocity should point below the horizon.

The Ferrari with less momentum will stop first.

The given parameters:

The momentum of each vehicle is calculated as follows;

P1 = m1v1 = 4535924 x 4.47 = 20,275,580.28 kgm/s

P2 = m2v2 = 1474.175 x 111.76 = 164,753.8 kgm/s

[tex]Ft = mv\\\\t = \frac{mv}{F}[/tex]

When the same force is applied, the object will less momentum will stop first.

Since the vehicle less momentum will stop first, thus we can conclude that the Ferrari with less momentum will stop first.

Answer:

1 watt is the same as the transfer of 1 joules per second.

1 watt is the same as the transfer of energy at a rate of 1 joule per second.

A watt is a unit of power, representing the amount of energy transferred or converted per unit of time. Specifically, 1 watt is equivalent to 1 joule of energy being transferred every second. It is a common metric used to measure the rate of energy flow or work done in various systems. For example, a 100-watt light bulb converts electrical energy into light and heat at a rate of 100 joules per second. Understanding power in terms of watts helps us quantify and compare the efficiency and performance of different devices and processes.

The answer is "0.047".

Explanation:

Given value:

[tex]\to t_{\frac{1}{2}}= 0.4406\\\\\to V=0.9375 V_{max}[/tex]

Calculating the capacitance:

[tex]\to V=V_{max} (1-e^{\frac{-t}{Rc}})[/tex]

In this, the t = time, which is taken to calculates its maximum voltage.

[tex]\to 0.9375 V_{max} = V_{max}(1-e^{- \frac{t}{103\times(165.279\times10^{-6})}})\\\\\to e^{- \frac{t}{103\times(165.279\times10^{-6})}}= 0.0625\\\\\to - \frac{t}{103\times(165.279\times10^{-6})} = \ln(0.0625)\\\\\to -t= 0.01702\times(-2.77258) \\\\ \to -t = -0.04719 \\\\ \to t= 0.04719 \approx 0.047 \ s[/tex]
