Explain why Pluto has been re-categorized as a dwarf planet.

Physics
1 answer:
chubhunter [2.5K]3 years ago
7 0

Explanation:

According to International Astronomical union a planet must satisfy the following three conditions-

1. It should orbit around sun(parent star).

2. It should have enough gravity to maintain almost spherical shape.

3. It should have cleared its neighbourhood around its orbit.

Pluto does not fulfill the third criteria and hence it has been re-categorized as dwarf planet.

what is the momentum of a child and a wagon if the total mass of the child and wagon is 22kg and the velocity is 1.5m/s?
antoniya [11.8K]

Answer:

33 kg m/s

Explanation:

The momentum of an object is given by:

p=mv

where

m is the mass of the object

v is the velocity of the object

In this problem, the total mass of the child and the wagon is m =22 kg, while the velocity is v = 1.5 m/s, therefore the momentum is

p=mv=(22 kg)(1.5 m/s)=33 kg m/s

An inventor develops a stationary cycling device by which an individual, while pedaling, can convert all of the energy expended
Eddi Din [679]

Answer:

Emec = 94050 [J]

Explanation:

In order to solve this problem, we must understand that all thermal energy is converted into mechanical energy.

The thermal energy can be calculated by means of the following expression.

Q=m*C_{p}*(T_{final}-T_{initial})

where:

Q = heat [J]

Cp = specific heat of water = 4186 [J/kg*°C]

m = mass = 300 [g] = 0.3 [kg]

T_final = 95 [°C]

T_initial = 20 [°C]

Now we can calculate the heat, replacing the given values:

Q=0.3*4180*(95-20)\\Q= 94050[J]

Since all this energy must come from the mechanical energy delivered by the exercise bike, and no energy is lost during the process, the mechanical energy must be equal to the thermal energy.

Q=E_{mec}\\E_{mec}=94050[J]

Describe how a unique position of the sun , earth, and moon creates a lunar eclipse
Serggg [28]
A eclipse of the sun can only occur at a new moon when the moon passes between earth and sun. If the moons shadow happens to fall upon earths surface at a time, you'll see some portion of the suns disk covered or aka eclipsed by the moon.. I hope that helps
