The weight of the rock will be lessened by the weight of the same volume of water. If the rock weighs less than that volume of water, it will float (as does pumice). Thus, if you had a rock that has a density (weight/volume) of 2 times the same volume of water, it would weigh one half of its dry weight when in water.
What else can I help you with?
According to Newton's laws a rock and a pebble will fall at the same?
No Because of massrate of acceleration, if they have the same outer shape (for friction) then they will reach the ground at the same time regardless of weight
Is the force of gravity greater less or equal in water than on land?
The force of earth's gravity on an object in water is the same as the force of gravity on it when it's on land. What's up with that? There is an extra force operating in water, and it's called buoyancy. An object put in water, like a rock, will displace an amount of water equal to its volume. The water pushes up on the object with a force equal to the effect of gravity on that volume of water that has been displaced by the object. That makes the object "lighter" when it's under water. The water's buoyancy is operating against the force of gravity. What happens when an object is placed in water and it's overall density is less than that of water? It does something amazing. It floats. Take a tennis ball. Hold it in the hand and drop it. It falls to the ground. Put that same tennis ball in a bucket of water. It floats. (It displaces its equivalent mass of water, though.) Has gravity taken the day off? Nope. Why doesn't gravity pull the ball to the bottom of the bucket? Buoyancy. Hey, since you've got that big bucket of water, get a big rock about the size of that tennis ball or so. Hold it in your hand. Heavy, right? Yeah. Now, holding the rock the same way, lower it into the bucket of water. You should be able to feel the difference in the amount of force required to hold the rock. It's "lighter" all of a sudden when it's under the water because of the effect of buoyancy. Buoyancy vs. gravity. An interesting matchup. Think we can book this into one of the big Vegas casinos and score a mega-buck pay-per-view contract?
How do you beat rock aris?
My Gravity Perseus sent Rock Aries flying so Gravity Perseus beats Rock Aries.But at the same time it broke Gravity Perseus a little but it still survived.
What is the weight of 1m3 volume of steel?
1m3 of steel is the same as the first answer 7840Kg.
What is a healthy weight for a 16 year old female 5'5 tall and does martial arts regularly?
The same weight for any athletic girl, around the same height. Use a health book, or google healthy wait scale on google.
What happens to to the volume of a container when a rock is added?
Placing a rock in a container does not alter the volume of the container, although it does occupy some of that volume.
What is the best way to measure water absorption capacity of rock?
Measure the rock and put it in water for an hour and check its weight, do it for another hour and so on until the weight stays the same
Why doesn't a bowl of water weigh more when you poke your finger into the water?
When you poke your finger into the water, you displace the water that your finger occupies, causing it to overflow out of the container. The weight of the water displaced is equal to the weight of your finger, so the overall weight of the bowl of water remains the same despite the displacement.
What do you do in order to measure the volume of a rock?
Irregular objects can be volumetrically measured with three simple tools; a scale, a container large enough to contain the entire object, and enough water to fill the container. If you fill the container with water and weigh it, fully submerge the object in the water and remove it, compare the final mass of the container and water to the container full of water, the difference between the two in grams is the same as the volume of the object in cubic centimeters.
A student weighs a container and then adds air When the student weighs the container again the weight will be?
Greater than before, since the added air increases the total weight of the container.
How big is a water tank?
About the same size as a water container.
Would water pressure be the same at the same depth in two containers that had very different shapes?
Yes, water pressure at the same depth is determined by the height of the water column, not the shape of the container. As long as the depth is the same in both containers, the water pressure will be equal.
If two immiscible liquids are joined in the same container one liquid will rise to the top of the container because of its?
molecular weight
If a rock and tank of water together weigh 100 pounds what will it weigh when the rock is in the tank?
When the rock is placed in the tank of water, the total weight will remain the same at 100 pounds. This is due to Archimedes' principle, which states that an object submerged in a fluid experiences a buoyant force equal to the weight of the fluid displaced by the object, thus offsetting the weight of the rock.
What will happen when cold air and warm are added to the same container?
when cold and warm air are added in the same container it causes water.
Why does a stone feel lighter when it was under water?
because the upthrust force of the water acting on the stone was pushing the stone upwards meaning it was acting against the downwards weight of the stone (its weight). This meant that the downwards force was decreased and therefore felt lighter :)
Is the volume of air inside a container still the same when some water is poured inside?
No, the water displaces the air if the container is open.
