Answer:

1) Has a rocky, metallic composition -Both

2) Experiences retrograde rotation, spinning clockwise as viewed from above- Venus

3)Experiences the greenhouse effect, which warms the planet - Both

4) Is the densest planet in the solar system - Earth

5) Is located an ideal distance from the Sun, allowing it to support life -Earth

6) Is one of the brightest objects in the night sky, sometimes mistaken for a star-Venus

Explanation:

Venus and Earth are terrestrial planets. They have rocky surface. Venus is characterized by a very thick atmosphere which traps the sun light and makes it the hottest planet of the solar system. Greenhouse effect warms both the planets.

Earth is the only planet on which life exists. It is located at ideal distance from the Sun which helps to maintain sustainable conditions -temperature to support life on it. Venus is known as morning and evening star as it is the brightest objects.

Earth is the densest planet of the solar system having density 5.51 g/cm³. Venus experiences retrograde rotation due to the tilt of its axis (177.3°). Due to this tilt it appears to rotate in opposite direction than other planets.

1). both

2). Venus

3). Venus catastrophically; Earth too but much less.

4). Earth

5). Earth

6). Venus (It would be pretty hard for US to mistake Earth for a star.)

A school bus moves slower and slower. Using what you have learned about forces, explain why the bus moves slower and slower.
Levart [38]

Answer:

I don't exactly know what you learned but it could be because of more friction or the bus was running out of gas.

If an electron is accelerated from rest through a potential difference of 9.9 kV, what is its resulting speed
beks73 [17]

Answer:

v = 5.9 x 10⁷ m/s

Explanation:

The kinetic energy of the electron in terms of potential difference is given as:

K.E = eV--------------- equation (1)

where,

e = charge on electron = 1.6 x 10⁻¹⁹ C

V = Potential Difference = 9.9 KV = 9900 Volts

The kinetic energy in general is given as:

K.E = \frac{1}{2}mv^{2}\\--------- equation (2)

where,

m = mass of electron = 9.1 x 10⁻³¹ kg

v = speed of electron = ?

Therefore, comparing equation (1) and equation (2), we get:

\\\frac{1}{2}mv^{2} = eV\\\\\frac{1}{2}(9.1\ x\ 10^{-31}\ kg)v^{2} = (1.6\ x\ 10^{-19}\ C)(9900\ volts)\\\\v = \sqrt{34.81\ x\ 10^{14}} \\

<u>v = 5.9 x 10⁷ m/s</u>

Raul dug a hole in his yard to repair a water pipe. It took him 2 seconds to apply a force of 50 Newtons to push the shovel 0.25
Sergeu [11.5K]

Answer:

Option B. 6.25 J/S

Explanation:

Data obtained from the question include:

t (time) = 2secs

F (force) = 50N

d (distance) = 0.25m

P (power) =?

The power can be obtained by using the formula P = workdone/time.

P = workdone / time

P = (50 x 0.25)/ 2

P = 6.25J/s

2 objects have a total momentum of 400kg m/s, they collide. Object A’s mass is5kg &amp; object B’s mass is 11kg. After the colli
ss7ja [257]

Answer:

Explanation:

We shall apply law of conservation of momentum .

Momentum before collision = momentum after collision .

Momentum before collision = 400 kg m/s

Momentum after collision = 5  x v + 11 x 15

where v is velocity of A after the collision .

5  x v + 11 x 15 = 400

5 v = 400 - 165

5v = 235

v = 47 m /s .
