Answer:

Seven

Explanation:

The rules for significant digits are:

Non-zero digits are always significant.
Zeros between significant digits are also significant.
Trailing zeros are significant only after a decimal point.

Here, the 2, 4, 9, and 2 are significant because they are non-zero digits.

The first two 0s are significant because they are between significant digits.

The last 0 is significant because it is a trailing zero after a decimal point.

Therefore, all seven digits are significant.

A typical white dwarf is __________. A typical white dwarf is __________. about the same size and mass as the Sun but much hotte

Ulleksa [173]

Answer:

A typical white dwarf is about as massive as the Sun, yet only slightly bigger than the Earth.

Explanation:

A typical white dwarf is about as massive as the Sun, yet only slightly bigger than the Earth.

White dwarfs are one of the densest elements in the universe, surpassed only by neutron stars and black holes. They can be considered as medium mass stars that fuses hydrogen into helium

Given the word equation below:

gulaghasi [49]

Answer:

Sodium and water

Explanation:

We are given with the word equation :

sodium + water + sodium hydroxide + hydrogen

It is required to find that the reactants of the above equation.

In terms of chemical formula we can write it as :

$Na+H_2O\rightarrow NaOH+H_2$

Reactant of a chemical equation are the elements that are present on its LHS. These are the components of which the equation is composed of. So, the reactants of the given equation are sodium and water.

A rock from Mars experiences a 263% increase in its weight once it arrives on Earth. What accounts for this increase in weight?

leva [86]

The mass of Mars is smaller than that the mass of Earth, therefore the acceleration of gravity on Mars is much less than that the acceleration of gravity of the Earth.

The weight of an object is directly proportional to the magnitude of the gravitational acceleration of the planet where it is.

In this case, the gravitational acceleration in Mars is 3.711 m/s² and that of the planet Earth is 9.807 m/s².

The acceleration of gravity on Earth is 2.63 times greater than that the acceleration of gravity on Mars. This explains that the same object weighs 263% more on earth

Two electrically opposite charges are separated by a fixed distance. Which action will provide the greatest increase in the forc

Alex73 [517]

Explanation:

The electric force between charges is given by the formula as follows :

$F=\dfrac{kq_1q_2}{r^2}$

k is electrostatic constant

r is distance between charges

Here, charges are equal and opposite. So,

$F=\dfrac{kq^2}{r^2}$

It is clear the force is inversely proportional to the distance between charges and directly proportional to the product of charges. So, greatest force will be providing by :

Increasing the magnitude of charges
Decreasing the distance between charges.
