A person's weight will be greater on Jupiter than on earth
Artist 52 [7]3 years ago
4 0

Answer:  A person’s <u>Mass</u> will be the same on Jupiter and Earth. A person’s <u>Weight</u> will be greater on Jupiter than on Earth.

Explanation:

Amount of matter contained in a body is known as mass (m). It is measured in grams or kilo-grams.

Weight is the force of gravity acting on an object. It is the product of the mass and acceleration due to gravity. It is measured in Newtons (N).

W = m g

Acceleration due to gravity varies with strength of gravity of different planets. Because, Jupiter’s strength of gravity is greater than Earth’s strength of gravity, the person would have greater weight on Jupiter than on Earth but same mass. Mass is constant everywhere.

How much energy is required to take 500g of ice at -40 degrees to water at room temperature (22 degrees Celsius)? Show work pls
Minchanka [31]

Answer: Given that:

Mass (m) = 20 g = 0.02 Kg,

temperature (T₁) = -10°C = -10+273 = 263 K

temperature (T₂) = 10°C = 10+273 = 283 K

Specific heat of water (Cp) = 4.187 KJ/Kg k

We know that Heat transfer (Q) = m. Cp.( T₂ - T₁)

                                                   = 0.02 × 4.187 × (283-263)

                                                Q = 1.67 KJ

Heat transferred is 1.67 KJ

Three charged particles are placed at each of three corners of an equilateral triangle whose sides are of length 3.3 cm . Two of
sweet [91]

Answer:

1.44\times 10^{-3} N

Explanation:

We are given that three charged particle are placed at each corner  of equilateral triangle.

q_1=-8.2 nC,q_2=-16.4 nC,q_3=8.0nC

q_1=-8.2\times 10^{-9} C

q_2=-16.4\times 10^{-9} C

q_3=8.0\times 10^{-9} C

Side of equilateral triangle =3.3 cm=\frac{3.3}{100}=0.033m

We know that each angle of equilateral angle=60^{\circ}

Net force=F =\sum\frac{kQq }{d^2}

Where k=9\times 10^9 Nm^2/C^2

If we bisect the angle at q_3 then we have 30 degrees from there to either charge.

Direction of vertical force  due to charge q_1 and q_2

Therefore, force will be added

Vertical  force=9\times 10^9\times q_3(q_1+q_2)\frac{cos30}{(0.033)^2})

Vertical net force=9\times 10^9\times 8\times 10^{-9}(-8.2-16.4)\times 10^{-9}\times 10^6\times\frac{\sqrt3}{2\times 1089}

Vertical  force =9\times 8(-24.6)\times 10^{-9}\times 10^6\times 1.732\times \frac{1}{2178}

Vertical  force=-1.41\times 10^{-3}N (towards q_1}

Horizontal component are opposite in direction then will b subtracted

Horizontal force=9\times 10^9\times 8\times 10^{-9}(-8.2+16.4) \times 10^{-9}\times \frac{sin30}{(0.033)^2}

Horizontal force=0.27\times 10^-3} N(towards q_2

Net electric force acting on particle 3 due to particle =\sqrt{F^2_x+F^2_y}

Net force=\sqrt{(-1.41\times 10^{-3})^2+(0.27\times 10^{-3})^2}

Net force=1.44\times 10^{-3} N

In a Broadway performance, an 83.0-kg actor swings from a R = 3.90-m-long cable that is horizontal when he starts. At the bottom
Veseljchak [2.6K]

Answer:

h = 2.821\,m

Explanation:

The speed of the actor before the collision is found by means of the Principle of Energy Conservation:

(83\,kg)\cdot(9.807\,\frac{m}{s})\cdot (3.90\,m) = \frac{1}{2}\cdot (83\,kg)\cdot v^{2}

v = \sqrt{2\cdot (9.807\,\frac{m}{s^{2}} )\cdot (3.90\,m)}

v \approx 8.746\,\frac{m}{s}

The speed after the inelastic collision is obtained by using the Principle of Momentum Conservation:

(83\,kg)\cdot (8.746\,\frac{m}{s} )+(55\,kg)\cdot (0\,\frac{m}{s} ) = (83\,kg + 55\,kg)\cdot v

v = 5.260\,\frac{m}{s}

Lastly, the maximum height is determined by using the Principle of Energy Conservation again:

\frac{1}{2}\cdot (138\,kg)\cdot (5.260\,\frac{m}{s} )^{2} = (138\,kg)\cdot (9.807\,\frac{m}{s^{2}} )\cdot h

h = \frac{(5.260\,\frac{m}{s} )^{2}}{9.807\,\frac{m}{s^{2}} }

h = 2.821\,m

Why do windows have two panes of glass separated by a layer of air
Soloha48 [4]

Air is a poor conductor of heat.  The air trapped between the two panes is a pretty good <em>insulator</em>.  It does a lot to prevent heat from flowing through the windows ... keeping heat IN during the Winter, and OUT during the Summer.

g what are the bands of electromagneitc radiation and how are they related to energy frequency and wavelength
ch4aika [34]

Answer:

The details of bands is given in explanation.

Explanation:

The electromagnetic waves are differentiated into different bands based upon their wavelengths and frequencies. The names of different bands are as follows:

1. Radio Waves

2. Micro Waves

3. Infra-red

4. Visible light

5. Ultra Violet

6. X-rays

7. Gamma Rays

<u>The frequency of every region or rays increases from 1 through 7</u>. The <u>energy of rays also increase from 1 through 7</u>. Since, the wave length is inversely related to energy and frequency, thus the <u>wavelength of rays decrease from 1 through 7</u>.

A detailed information of the bands is provided in the picture attached.
