Earth 24 hours, 365 days, so c
GREYUIT [131]3 years ago
3 0

Answer: The correct answer is option (C).

Explanation:

Duration of 1 day on Earth  = 24 hours

Duration of 1 complete revolution of the Earth around the sun:

1 year = 31,536,000 seconds.

Duration of the day on the Saturn = 10 hours = 36,000 seconds

Duration of 1 complete revolution of the Saturn around the sun:

= 10 years = 315,360,000 seconds.

1 earth year = 365 days

1 hour = 60 minutes

1 minutes = 60 seconds

From the given information, we can conclude that duration of the rotation of the earth is longer than the duration of rotation of the Saturn.

Whereas the we can conclude that duration of the revolution of the earth is shorter than the duration of revolution of the Saturn.

Hence, the correct answer is option(C).

A 5.00-cm cube of magnesium has a mass of 217.501 g. What is the density of magnesiummetal?
Doss [256]

Answer:

d = 43.5 g/cm³

Explanation:

Given data:

Mass of magnesium cube = 217.501 g

Volume of magnesium cube = 5.00 cm³

Density of magnesium cube = ?

Solution:

Formula:

d = m/v

d = density

m = mass

v = volume

by putting values,

d = 217.501 g/ 5.00 cm³

d = 43.5 g/cm³

What is the oxidation number of chlorine in HClO4?
Elza [17]

CIO4-=-1

CI=4O=-1

O has a 2- oxidation change so

CI+4(-2)=-1

CI+(-8)=-1

CI=-1+8=7

So the oxidation number of chlorine is 7 in this case

Answer:

F = 30 N

Explanation:

Given data:

Mass of toy train = 1.5 kg

Acceleration of train = 20 m/s²

Amount of force acting on it = ?

Solution:

The net force on object is equal to the its mass multiply by its acceleration.

Formula:

F = ma

F = force

m = mass

a = acceleration

Now we will put the values in formula.

F = 1.5 kg × 20ms⁻²

F = 30 kg.ms⁻²

kg.ms⁻² = N

F = 30 N
