Answer:

A force that pushes or pulls is known as Newton's third law of Motion.

Explanation:

Newton's Third Law of Motion. Newton's Third Law of Motion states that for each action, there's an equal and opposite reaction. What this suggests is that pushing on an object causes that object to keep off against you, the precise same amount, but within the other way.

A balloon of diameter 20.0 cm is filled with helium gas at 30°C at 1.00 atm. How
bogdanovich [222]

Answer:

N = 3.54 * 10²³ atoms

Explanation:

The formula to apply here is the idea gas law;

PV = nRT  where ;

P= pressure of the gas= 1.013 * 10⁵ Pa

V= volume of the gas = 4/3 * 3.14 *0.15³= 0.01414 m³

n= amount of a substance = ?

R= ideal gas constant= 8.314

T= temperature= 293 K

Applying the values to the formula;

PV = nRT

1.013 * 10⁵ * 0.01414 = n * 8.314*293

n= 1.013 * 10⁵ * 0.01414 / 8.314*293

n= 0.588 moles

1 mole = 6.022 * 10²⁷ atoms/ mole

0.588 moles = 0.588 * 6.022 * 10²⁷

N = 3.54 * 10²³ atoms

If you were in a canoe on a calm lake and you threw a heavy stone as far is you could out the canoe what would the canoe do
Bezzdna [24]

This is conservation of momentum. At the beginning the total momentum is zero. When you throw the stone you give the stone a positive momentum, which means you must have a negative momentum (when I say negative I mean in the opposite direction of the direction of the stone) so that the total momentum is still zero. You and the canoe will move in the opposite direction of which you threw the stone.

Given that the acceleration of gravity at the surface of Mars is0.38 of what it is one Earth, and that Mars' radius is 3400 km,d
evablogger [386]

Answer:

1.156\times 10^{24}\ kg

Explanation:

Given:

Gravity of Mars = 0.38 times the gravity at Earth

Gravity of Earth is, g_{Earth}=9.8\ m/s^2

Radius of Mars (R) = 3400 km

Mass of mars (M) = ?

We know that, the acceleration due to gravity  of a planet of mass 'M' and radius 'R' is given as:

g=\dfrac{GM}{R^2}

Now, as per question:

g_{Mars}=0.68g_{Earth}

Plug in 9.8 for g_{Earth} and solve for g_{Mars}. This gives,

g_{Mars}=0.68\times 9.8=6.67\ m/s^2

Now, plug in this value in the above equation and solve for 'M'. This gives,

6.67=\frac{6.67\times 10^{-11}M}{(3400\times 10^3)^2}\\\\1.156\times 10^{13}=10^{-11}M\\\\M=\frac{1.156\times 10^{13}}{10^{-11}}\\\\M=1.156\times 10^{24}\ kg

Therefore, the mass of Mars is 1.156\times 10^{24}\ kg.
