It is because both of them are attracted towards earth where the heavier body gravity field influence is more in comparision to small. For eg; there are two magnet with less power in besides of huge power or magnetic influence then both of the less power magnet are attracted towards the huge one rather than attracting themselves.


Hope its helps u!

How do you know that waves sent from the sun to earth are not mechanical waves? Explain
Anna71 [15]
Mechanical waves require matter to travel medium. If there is no substance or matter to travel through, mechanical waves cannot propagate.

Since space is mostly vacuum, there is no medium for waves to travel through: waves sent by the sun (electromagnetic waves) are not mechanical waves

A man seeking to set a world record wants to tow a 101,000-kg airplane along a runway by pulling horizontally on a cable attache
NemiM [27]

Answer:

6.19 x 10^{-3} m/s^{2}

Explanation:

For this exercise we need to sum the forces on the y-axis and x-axis as follows:

∑F_{y} = N - mg = m.a_{y} = 0

From the exercise, we deduce there is no motion in y-axis, so:

N = mg

Then for x-axis we have:

∑F_{x} = H - f^{s} = m.a_{x} = 0

Now, from the exercise we deduce that we are looking for the greatest static friction which means to have the maximun static friction to start moving, so at this point the acceleration is zero, so we can find horizontal force (H), which then will act in the airplane to move it. Therefore we have:

H = f^{s} = f^{sma_{x} } = u_{s}N = u_{s}mg

H = (0.76)(84Kg)(9.8m/s^{2})

H = 625.63 N

Now we apply this force to the weight of the plane to find the greatest acceleration the mann can give to start moving the plane.

a = \frac{F}{m} = \frac{H}{m}

a = \frac{6325.63N}{101000Kg}

a = 6.19 x 10^{-3} m/s^{2}
