Physics
I need help on two problems :P 1. A spherical balloon is partially blown up and its surface area is measured. More air is added increasing the volume of the balloon. If the surface area of the balloon expands by a factor of 2.0 during this procedure, by what factor does the ra...

Submit pseudocode and a flowchart for the following programming exercise: Fat Gram Calculator Design a program that asks for the number of fat grams and calories in a food item. Validate the input as follows: - Make sure the number of fat grams and calories are not less than 0...

Watts is not a speed. England is to big, be more specific. There is no such thing as a "Ground Rate Ratio", trains can't go from England to France, and there was never a second train..

Oh and trains have nothing to do with airspeed..

Watts is not a speed. Wisconsin is not a city. There is no such thing a a ground-rate ratio. You can't go from England to France by train, and there was never a second train.

On your first day at work for an appliance manufacturer, you are told to figure out what to do to the period of rotation during a washer spin cycle to triple the centripetal acceleration. You impress your boss by answering immediately. Express in terms of T. Equation I believe...

howdy, just cant seem to get this question, can anyone express this question in words i can get?! thanks A sound wave of wavelength 0.8 m divides into two equal parts that recombine to interfere constructively, with the original difference between their path lengths being |r2|...

A rocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration 58.8m/s^2 . The acceleration period lasts for time 8.00s until the fuel is exhausted. After that, the rocket is in free fall. Find the maximum height y_max reached by th...

The acceleration of a bus is given by a_x(t)=At, where A= 1.21 is a constant. A)if the bus's velocity at time t_1= 1.14s is 5.03m/s, what is its velocity at time t_2= 2.04 ? B)if the bus's velocity at time t_1= 1.14s is 6.02m/s, what is its velocity at time t_2= 2.04 ?

Algebra 1a
I posted this early, I don't understand the answer, Two angles are complementary. The sum of the measure of the first angle and one-fourth the second angle is 87.75 degrees. Find the measures of the angles? What is the measure of the smaller angle? What is the measure of t...
