Answer:

here we can say that acceleration of the satellite is same as the gravitational field due to Earth at that location

Explanation:

As we know that gravitational field is defined as the force experienced by the satellite per unit of mass

so we will have

E = \frac{F}{m}

now in order to find the acceleration of the satellite we know by Newton's II law

F = ma

so we will have

a = \frac{F}{m}

so here we can say that acceleration of the satellite is same as the gravitational field due to Earth at that location

Answer:

The gravitational field and the acceleration point in the same direction.

The magnitudes of the acceleration and the gravitational field strength are equal.

These are the two answers

Which is true regarding diffusion and osmosis? Question 3 options:
Scilla [17]

Answer:

Option (A)

Explanation:

Diffusion is defined as the transfer of particles such as ions or molecules from a higher concentration region to a lower concentration region.

Osmosis is a special type of diffusion in which the solvents such as water are allowed to move from a region of higher to a lower concentration through a layer of a semi-permeable membrane. This is an energy-independent process and occurs along the concentration gradient.

Thus, the correct answer is option (A) that is true for both osmosis and diffusion.

A 100 Newton force applied to a machine lifts a 400 N object. What is the actual mechanical advantage of
uranmaximum [27]

Answer:

m = 4

Explanation:

It is given that,

A 100 Newton force applied to a machine lifts a 400 N object.  

We need to find the mechanical advantage of  this machine.

The mechanical advantage of a machine is given by the ratio of output force to the input force.

Here, output force is 400 N and input force is 100 N

So, mechanical advantage becomes :

m=\dfrac{400}{100}\\\\m=4

So, the mechanical advantage of this machine is 4.

We cab calculate work because we know the force and distance.what else would we need to know to calculate power
san4es73 [151]

We would need to know how long it took to do the work.

Power = (work) / (time).

Air resistance is a nonconservative force. It always opposes the motion of an object. An airplane flies from New York to Atlanta
gulaghasi [49]

Answer:

c. is negative

Explanation:

When the magnitude of force is multiplied with the force vector's projection along the direction of the vector of displacement which is negative as it is a resistive force we get the work done.

As the wind is acting in opposite direction of the force which is being applied by the plane the work done will be negative. Also, the net work will be the sum of many smaller negative quantities.

Hence, the answer here is negative.
