Having minor homework questions or simply want to make sure your homework answers are correct? Then use our free service to get quick answers to your homework questions in mathematics, physics, programming, economics, chemistry and biology. We already have a database of multiple homework questions and answers you can look through . If you can’t find the solutions to your homework problems, then post your homework questions and find a well-formulated answer from a professional within a very short timeframe.
Please save your time and DO NOT send us your full assignments or not precise, well stated questions in mathematics, physics, programming, economics, chemistry or biology as they will be ignored. In this section we can answer only your short questions of qualitative, primary theoretical nature (for FREE!). Use filters to display the questions to a particular subject or section. By entering your e-mail in the box "Search" you can browse the questions posted exclusively by you. Do not worry if you cannot find your question in the list after it has been submitted; every question is being checked by a moderator and appears in the list only after its approval.
A block of mass m = 2.00 kg is released from rest at h = 0.800 m from the surface of a table, at the top of a θ = 30.0° incline as shown below. The frictionless incline is fixed on a table of height H = 2.00 m.
(a) Determine the acceleration of the block as it slides down the incline.
(b) What is the velocity of the block as it leaves the incline?
(c) How far from the table will the block hit the floor?
(d) How much time has elapsed between when the block is released and when it hits the floor?
a bat flying in a cave emits a sound and receives it echo .2 s later. How far away is the cave wall? Assume the speed of sound to be 340 m/s. Answer in units of m.
1 kg of ice at -4°C was placed in a Styrofoam icebox of dimensions 60 cm x 30 cm x 30 cm and wall thickness 3 cm. Calculate how long it will take before the ice melts if the outside temperature is 30°C.
[ Lf(ice)= 335 kJ/kg; Cwater =4190 Jkg-1°C-1 ; k (Styrofoam) = 0.01 J.s-1 .m-1 . °C-1 ; Cice 2.09 Kj/(kg. °C).
