a plastic ball has radius 12.0 cm and floats in water with 24.0 % of its volume submerged


A things drifts with half its volume under the surface area of the water. The weight of the displaced water is 2000 N. The density of water is 1000 kg/m3. A bowling round of mass 7.5 kg as well as size 18 cm rolls without slipping down a 10-m bowling lane with a constant speed 4.3 m/s.

a plastic ball has radius 12.0 cm and floats in water with 24.0 % of its volume submerged.

Spool A is connected to the ceiling by a thread, while spool B is not attached to the ceiling. An “X” is marked on the flooring straight underneath each spindle. Consider the thread to be massless.

You pull on a spring that is attached to a wall surface. You find that you should apply a 4-N pressure to stretch the spring by 2 centimeters from its un-stretched size. Just how much pressure must you relate to compress the spring by 2 centimeters from its unstretched length? D) Zero N E) You can not answer this question with the info given. C) The buoyant force initial boosts and afterwards remains constant. C) The resilient pressure coincides in both instances. C) The absolute pressure increases by Δp.

What is the minimum area of the floe that will simply sustain the bear in saltwater of thickness 1030 kg/m3? Determine the stress applied on the ground because of the weight of 79 kg person standing on one foot. if the bottom of the individual’s foot is 13 centimeters broad and also 28 centimeters long. A) The stress all over in the oil will boost by Δp.

85) 3 balls are relocating along a straight line having the immediate positions shown in the number. At that split second, find the location and speed of the center of mass of this system. What is the buoyant force on the coastline round in air? The density of the plastic is about 2 mm-negligible contrasted to the radius of the round. The illustration shows 2 transverse waves taking a trip on two strings. The direct thickness of each string coincides, and the weight of each block coincides.

C) The rate of the things is continuous. 3 masses A, B, and also C exist along the x-axis as shown. What is the internet gravitational force, size and direction, that acts on mass B?
