Why it is difficult to lift a large stone on the surface of the earth but easy to lift a smaller one?
Large stone has more mass compare to a small one. And mass is directly proportional to weight where 'g' is constant for every object on earth. As a result larger stone has more weight than that of smaller. That's why it is difficult to lift larger stone on the surface of the earth but easier to lift a smaller one.
Does a star whose mass is spread through a large volume has a high density?
The density will not be as large as one with the same mass which is spread over a smaller volume.
How many electrons does it take to equal the mass of one neutron?
One neutron is approximately equal in mass to one proton. Since an electron is much smaller in mass compared to a neutron or a proton, it would take a large number of electrons to equal the mass of one neutron.
Material moves in one large mass?
A lot of different things move in one large mass. One common example is a glacier, a large mass of ice that moves as one unit.
Which is the smaller mass?
If the units are the same, that will be the one with the smaller number of units.
What has a higher density a small pure gold ring or a large pure gold ring?
The smaller pure gold ring will have a higher density than the larger one due to its smaller volume and higher mass. Density is a ratio of mass to volume, so as the volume decreases and the mass remains constant, the density increases.
Why is a vehicle with wheels that have a large diameter more likely to roll over than a vehicle with wheels that have a smaller diameter?
The larger the wheels have a higher center of mass than a smaller one. The higher the center of mass, the smaller the tilt needed to cause the wheel's center of mass to move outside its base and cause the wheel to roll over.
Why is it easer to change the motion of n objectwith a large mass than an object with a smaller mass?
It is easier to change the motion of an object with a smaller mass because it has less inertia, which is the tendency of an object to resist changes in its motion. Objects with larger mass have more inertia and resist changes in motion more strongly. This means it takes more force to change the motion of an object with a larger mass compared to one with a smaller mass.
What is a natural narrow water region which separates a large land mass from a smaller one?
A strait, or straits, eg, the Straits of Gibraltar, the Bass Strait.
How many kilograms of mass can one kilogram of helium lift?
About 0,85
How does a hydraulic lift work?
A hydraulic lift works by having pressure travel through a tube into another. One tube is smaller forcing air into the larger one in order to push and raise the lift.
can a person lift somebody taller than them?
It depends on how much mass the taller person has. Normally, a persons whos mass is one-third the person they are carrying can lift it with enough effort
