When a substance has a density that is less than the density of water, it floats. A wooden sphere has a radius of 4 centimeters and a mass of 250 grams. Will the wooden sphere float? Use the fact that the density of water is 1 gram per cubic centimeter. Round answers to the nearest hundredth. A. The density of the wooden sphere is 0.93 grams per cubic centimeter, which is less than the density of water, so it will float. B. The density of the wooden sphere is 1.24 grams per cubic centimeter, which is greater than the density of water, so it will not float. C. The density of the wooden sphere is 0.93 grams per cubic centimeter, which is less than the density of water, so it will not float. D. The density of the wooden sphere is 1.24 grams per cubic centimeter, which is greater than the density of water, so it will float.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
