Calculating the Density of Wax

2024-02-07 15:36:23

The density of the wax can be calculated by using the following formula: density = mass / volume. In this case, we know that the mass of the wax is 4.9 grams. To find the volume, we can subtract the weight of the wax and the bolt in air (98 mN) from the weight in water (78.4 mN). This gives us a weight difference of 19.6 mN. Now, using the density formula, we can plug in the known values and solve for the volume. The result will be in cubic meters, so we can convert it to cubic centimeters by multiplying by 1000000. Finally, dividing the mass by the volume will give us the density of the wax in grams per cubic centimeter. This is your solution.

Determining Pressure of Two Objects on a Table

2024-01-11 14:43:16

In order to determine whether the two objects are exerting the same pressure on the table, we need to first understand what pressure is. Pressure is defined as the force per unit area. Therefore, in order for the pressure to be the same, the two objects need to have the same force and the same area of contact with the table.

Looking at the figure on the left, we can see that both objects have the same weight and are placed at the same distance from the edge of the table. This means that the two objects have the same force acting downwards. However, their contact areas with the table are different. The object on the left has a smaller contact area with the table compared to the object on the right. This means that the object on the left is exerting a larger pressure on the table compared to the one on the right.

Therefore, the objects do not exert the same pressure on the table. To evenly distribute the pressure, the objects should be placed at the same distance from the edge of the table and have the same contact area with the table. This can be achieved by placing the objects side by side instead of one on top of the other.

Determining the weight of a body on a support

The weight of a body on a support is determined by several factors, including the mass of the body, the gravitational force acting on the body, and the reaction force from the support.

The mass of the body refers to the amount of matter contained within the body. This is a constant value and does not change with the type of support the body is on.

The gravitational force is the force exerted on the body by the Earth's gravitational pull. This force is dependent on the mass of the body and the acceleration due to gravity, and is represented by the equation F = mg, where m is the mass of the body and g is the acceleration due to gravity.

The reaction force from the support is the force that the support exerts on the body in order to keep it in equilibrium. This force is equal in magnitude but opposite in direction to the gravitational force acting on the body, and is represented by the equation F_support = -mg.

Therefore, the weight of a body on a support is determined by the magnitude of the gravitational force acting on the body and is equal to the mass of the body multiplied by the acceleration due to gravity. In other words, the weight of a body on a support is directly proportional to the mass of the body.
