Answer:

conservative

Explanation:

Nonconservative force is the force that depends on a path, however conservative does not depend on a path and it is not associated with the potential energy. When the work is done by an unconservative force, mechanical energy is added or removed. Friction is the best example for a non-conservative force. When these non-conservative forces are acting, the mechanical energy changes but these are not preserved.

hope this helped!

Answer: conservative

Explanation:

A conservative force is not path-dependent and does not change the overall mechanical energy of an object.

A conservative force is a force with the property that the total work done in moving a particle between two points is independent of the taken path, e.g. gravitational force or electric force.

A nonconservative force is one for which work depends on the path taken, e.g. frictional force.

Suppose that you travel to a planet that has 4 times the Earth's mass and 4 times the Earth's radius. Calculate how much more or

sweet [91]

Mass on the planet would be 4 times the mass on Earth.

Explanation: 

Given -

Let the mass of Earth = Me

Let the radius of Earth = Re

Mass of the planet, Mp = 4Me

Radius of the planet, Rp = 4Re

Weight on other planet, W = ?

Weight on planets is determined by the gravitational force

Gravitational force, F = GMm/r²

where, G = gravitational constant

M = Mass of the planet

m = our mass

r = radius of the planet

Gravitational force on Earth:

F = G X Me X ma/ Re² (ma = mass on earth)

Gravitational force on planet :

F = G X 4Me X mₓ/ (4Re)² (mx = mass on other planet)

Dividing both the equations, we get

mx = 4ma

Therefore, mass on the planet would be 4 times the mass on Earth.

The mass of 2 cm3 of gold is 38.6 grams. find the density of the gold. Could you please help me??

Alex Ar [27]

Density = mass/ volume (so here this is how you would solve the problem)

D = 38.6 g/ 2 cm3 (first step)

D= 19.3 g/cm3 ( Do math and then you would get this)

Hope this helps!! :)

A jet engine gets its thrust by taking in air, heating and compressing it, and

nadya68 [22]

Answer:

$F=ma=20\ Kg\ 400\ m/s^2=8,000\ Nw$

Explanation:

Thrust is known as a reaction force which appears when a system expels or accelerates mass in one specific direction. If we know the acceleration and the mass of the air expelled by the jet engine, we can compute the thrust .

The acceleration is calculated by using the dynamics formula

$\displaystyle a=\frac{v_f-v_o}{t}$

The values are

$v_f=500\ m/s,\ v_o=100\ m/s,\ t=1\ sec$

$\displaystyle a=\frac{500-100}{1}=400\ m/s^2$

The thrust is

$F=ma=20\ Kg\ 400\ m/s^2=8,000\ Nw$
