1. If a block of aluminum measures 4.0 cm x 5.0 cm x 2.0 cm is completely submerged in a tank of water, what volume of water does it displace?
2. What is the mass of the displaced water?
3. What is the weight of the displaced water?
4. How large of a buoyant force acts on the block?
5. The mass of the aluminum block is 108 g. Determine its density.
6. If you release the metal block, will it sink, or will it float to the surface? Explain your reasoning.
7. If the block was submerged in ethyl alcohol instead, would the tension in the string be bigger or smaller?
(With solution if it's okay with you, thank you so much)
If the density of a bar of gold is 19.3 g/cm3 and you cut it into 5 pieces, what is the density of each piece of gold
ψ=squar 2/L sin (nPie x/2) find the value of x
Ellen made an egg safety device that has a mass of 125 g. Her homework was to drop the device at a certain height of 1.0 meter, 1.5 meters and 2.0 meters. Calculate the net force of the impact during the collision.
Determine the force of gravitational attraction between the earth (m=5.98×10²⁴kg) and a 45 kg physics student if the student is in a private jet together with his family at 6750 feet above earth's surface. This would place the student a distance of 7.39×10⁶m from earth's center
Calculate the period of a simple pendulum if the length is 12 inches.
A 3.5 kg model car travels down a ramp that is 2.3 m tall. At the top of the ramp, it is
moving with an initial speed of 3.4 m/s. At the bottom of the ramp is a 5,0 cm flat
surface that has a spring on the end of it, with a spring constant of 75.0 N/m.
What is the speed of the car just as it hits the spring? The ramp has a coefficieht
of friction of 0.12.
