Answer:
There is no short answer.
Explanation:
In theory, the gravitational pull between the planets depends on their total mass and the distance between them. The sun has a mass of
kg, Jupiter has a mass of
kg and Earth has a mass of
kg.
Earth is closer to Jupiter than it is to the sun. The other planets that are behind jupiter are gone so that means the sun's pulling force's effect on jupiter is increased drastically since there is no force the balance that and that means that jupiter is going to get closer to earth.
The new center of mass of the new solar system is roughly located between earth and the sun, closer to earth.
I hope this answer helps.
Answer:
16 kg
Explanation:
M - container
m - oil mass
by definition of density ,
relative density is the ratio of the density of a substance to the density of water.
relative density = density/ density of water
density of oil = 1.2*1000 kgm⁻³ = 1200 kgm⁻³
1 Litre =10⁻³ m³
oil volume = 80 *10⁻³ m³
mass of oil = density * volume
= 1200*80*10⁻³
= 96 kg
Mass of container + mass of oil =112
mass of container = 112 - 96
= 16 kg
The distance between Mars and the Sun in the scale model would be 1140 m
Explanation:
In this scale model, we have:
represents an actual distance of
![d_1 = 1.0\cdot 10^5 km](https://tex.z-dn.net/?f=d_1%20%3D%201.0%5Ccdot%2010%5E5%20km)
The actual distance between Mars and the Sun is 228 million km, therefore
![d_2=228\cdot 10^6 km](https://tex.z-dn.net/?f=d_2%3D228%5Ccdot%2010%5E6%20km)
On the scale model, this would corresponds to a distance of
.
Therefore, we can write the following proportion:
![\frac{x_1}{d_1}=\frac{x_2}{d_2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx_1%7D%7Bd_1%7D%3D%5Cfrac%7Bx_2%7D%7Bd_2%7D)
And solving for
, we find:
![x_2=\frac{x_1 d_2}{d_1}=\frac{(50)(228\cdot 10^6)}{1\cdot 10^5}=1.14\cdot 10^5 cm = 1140 m](https://tex.z-dn.net/?f=x_2%3D%5Cfrac%7Bx_1%20d_2%7D%7Bd_1%7D%3D%5Cfrac%7B%2850%29%28228%5Ccdot%2010%5E6%29%7D%7B1%5Ccdot%2010%5E5%7D%3D1.14%5Ccdot%2010%5E5%20cm%20%3D%201140%20m)

Answer
t = 367.77 s = 6.13 min
Explanation:
According to the law of conservation of energy:
![Heat\ Supplied\ By \ Heater = Heat\ Absorbed\ by\ Glass + Heat\ Absorbed\ by\ Water\\Pt = m_gC_g\Delta T_g + m_wC_w\Delta T_w\\](https://tex.z-dn.net/?f=Heat%5C%20Supplied%5C%20By%20%5C%20Heater%20%3D%20Heat%5C%20Absorbed%5C%20by%5C%20Glass%20%2B%20Heat%5C%20Absorbed%5C%20by%5C%20Water%5C%5CPt%20%3D%20m_gC_g%5CDelta%20T_g%20%2B%20m_wC_w%5CDelta%20T_w%5C%5C)
where,
P = Electric Power of Heater = 300 W
t = time required = ?
m_g = mass of glass = 300 g = 0.3 kg
m_w = mass of water = 250 g = 0.25 kg
C_g = speicific heat of glass = 840 J/kg.°C
C_w = specific heatof water = 4184 J/kg.°C
ΔT_g = ΔT_w = Change in Temperature of Glass and water = 100°C - 15°C
ΔT_g = ΔT_w = 85°C
Therefore,
![(300\ W)(t) = (0.3\ kg)(840\ J/kg.^oC)(85^oC)+(0.25\ kg)(4184\ J/kg.^oC)(85^oC)\\](https://tex.z-dn.net/?f=%28300%5C%20W%29%28t%29%20%3D%20%280.3%5C%20kg%29%28840%5C%20J%2Fkg.%5EoC%29%2885%5EoC%29%2B%280.25%5C%20kg%29%284184%5C%20J%2Fkg.%5EoC%29%2885%5EoC%29%5C%5C)
<u>t = 367.77 s = 6.13 min</u>
Answer:
a) U = 735 J
, b) U = 125.7 J
, c) U = 0 J
Explanation:
The gravitational power energy is
U = mg y - mg y₀
The last value is a constant, for simplicity we can make it zero, if the lowest point is at the origin of the coordinate system, which in this case we will place in the lowest part
a) Rope is horizontal
The height in this case is the same length of the rope
y = 2.10 m
w = mg = 350 N
U = 350 2.10
U = 735 J
b) when the angle is 34º
y = L - L cos 34
y = L (1- cos34)
y = 2.10 (1- cos 34)
y = 0.359 m
U = 350 0.359
U = 125.7 J
c) in this case this point coincides with the reference system
y = 0
U = 0 J
