A metal block when fully immersed in a liquid of density 4kg/litre loses 15 kg.The same object when fully immersed in an unknown liquid loses 27kg.Calculate the density of the unknown liquid.-Just Cro
Frequency of sound waves can be measured DIRECTLY, given that it is easy to make a circuit or computer that can process frequencies on the order of a few hundred Hertz.
For any electromagnetic wave
Consider a rock that is thrown off a bridge of height 58 m at an angle θ = 23° with respect to the horizontal. If the initial speed the rock is thrown is 13 m/s, find the following quantities.

this was the experiment we did in class http://earthphysicsteaching.homestead.co…
if you scroll down you will see a nice simple diagram,
in the diagram it says Water Level (Resonant Surface)

A spelunker is surveying a cave. She follows a passage 160 m straight west, then 230 m in a direction 45 degrees east of south, and then 280 m at 30 degrees east of north. After a fourth unmeasured di
I have a few physics questions, could you please show me how you get the answer and show me what equation you use? Thank you sooo much in advance!Free- fall equations(no friction)

For example if I am asked to convert 58 miles/sec into km/hour how do i go about it? I already know how to convert between single units.. but am lost when it comes to double units-Revised version!

A hockey puck is sliding down an inclined plane with angle θ = 10.0° as shown in the figure below. If the puck is moving with a constant speed, what is the coefficient of kinetic friction between the
Please explain your reasoning-Look carefully at this equation. what does x^1/2 equal? Its the square root of x! so for any value at x^1/2, y will always = the square root of the x value. for instance
can someone explain to me how to do the problem below please? Thanks!
Starting from the front door of your ranch house, you walk 60.0 m due east to your windmill, and the you turn around and slowly w
A 200-g ball thrown vertically up with an initial speed of 20 m/s reaches a maximum height of 18 m.

I calculated it to be ~58357J (whole number) since m = 420kg and v=60/3.6 = 16.67m/s
k.e. = (1/2)mv² = (1/2)*420*(16.67)² = 58357J
but the answer says 3500J which means I am completely off. what am
Consider an experiment where a stopper is attached to a string which is also attached to a hanging mass at the other end. The radius of circular motion is constant (for the time-being), and the stoppe
