Gravity exerts a downwards force on all fluids.
The reason that any given part of the fluid stays still is that the upthrust around it is exactly equal to its weight at all times.
When an object DISP
A 320-g mass and a 400-g mass are attached to the two ends of a string that goes over a pulley
with a radius of 8.70 cm. Because of friction, the pulley does not begin to rotate. What is the
magnitude
Find the length of the spiraling polar curver = 3e^(4theta)
From 0 to2pi.-I will give you a preliminary argument first, which is that 3 e^(4 θ) becomes so large for θ = 2π, and does so much of its gr
I had an airplane lab, where we made our own paper airplanes and what not. We had to throw them several times, while adding paperclips for every 3 trials. Now my question is, as my mass increased, my
What mass of ethyl alcohol will give up 33,000 J of energy as it cools from 27°C to -3°C?
a. 2.41x109kgb. 0.566kgc. 1.92�109kgd. 0.453kg-You cant do this unless you are told the specific heat capacity
the time it takes to make 10 revolutions is ..
the answer is 5.6 seconds. i dont know how to get to the answer
please write step by step
thanks-10 revolutions is also 20π radians.
You can treat this
can someone please please help me with these phyiscs questions?
first, what resistance must be placed in parallel with a 155 resistor to make the equivalent resistance 115 ohms?
secondly, the resist
1. a car moves at 20ms-1 straight east, the driver is wearing his safety belt. the front end crumples by 1.55m.( the car and the driver therefore continue moving forward for 1.55m before they come to
Sound is transmitted through solids, liquids and gases as the vibration is passed from a molecule to its neighbors. Which of the heat transfer methods is this most similar to?
a. radiationb. conductio
On earth, the acceleration due to gravity is 9.8 m/s^2-9.8 m/s^2 * 4 seconds = 39.2 m/s.
You can look at the units of measurement to see what you have to do to solve this:
The unit for acceleration
Hello, I REALLY dont know how to solve this question and Id really like some help! Here is the question :
A locomotive pulls 2 wagons of the same mass. Show that the force of tension between the loco
I need a little help its a confusing question-Light refracts because when it goes from a less dense to a more dense medium its velocity slows down. So, consider a beam of light entering a block of gla
Many cooking pots have hard plastic or wooden handles. What is the reason for this?
a. The handles are made from a good conductor of heat so that the heat is drawn away from the pan to protect your ha
There are two branches of physics, Quantum Mechanics and Relativity .... I say two branches because the are not compatible with each other ...String theory is supposed to be able to combine the two br
Hi, im doing physics right now and I was wondering why a person is safe from lightning inside a car that has a metal body?
Thank you soo much! :) -Some people think that its because cars have rubber
