The graph below shows the average cost of monthly contract for four different cell phones in a European country from January to September in 2002. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words. Task 1 曲线图...
Steps to Use the Impulse-Momentum Theorem to Calculate the Average Force Step 1: Identify the mass, initial velocity, and final velocity of the object. Step 2: Calculate the change in momentum of the object using the formula {eq}\Delta p=m(vf-vi) {/eq} Step 3: Set...
Tip:When there are leftover variables in the formula, this means the acceleration is not constant over time. Be sure to include any units of measure in your answer to make it correct. References Ling, Sanny, & Moebs. Average and Instant. Acceleration. OpenStax University Physics. Retrieved f...
Steps for Calculating the Gravitational Force between Two Celestial Objects Step 1: Determine the known values such as the mass of the objects and the distance between them. Step 2: Determine what unknown value we are trying to find. Step 3: Determine which equations we will nee...
So, why is this flying and not just falling in a wacky costume? Read on to discover how physics, design and decades of experimentation have allowed wingsuit flyers to own the skies. Fall Slower and Farther The average skydiver plummets towards the surface of the Earth at a rate of 120 ...
to four-hour schedule, but you shouldn't stray more than a couple of hours outside that time frame. An average adult bladder can hold between one and two cups, and it typically takes nine to 10 hours to produce that much urine. If you hold your pee for longer than that, your ...
Probably one of the most famous, or infamous, siege weapons -- the catapult was used to cast projectiles into an enemy stronghold in an attempt to either weaken its defenses or break the will of those sheltered inside. From a physics point-of-view, the c
This problem needs the average impact force, so rearranging the equation gives: average impact force=change in kinetic energydistance traveled The distance traveled is the only remaining piece of information, and this is simply how far the object travels before coming to a stop. If it penetrates...
When they accelerate, the casing moves off immediately but the mass lags behind and the spring stretches with a force that corresponds to the acceleration. The distance the spring stretches (which is proportional to the stretching force) can be used to measure the force and the acceleration in ...
At the exit of the fan, let the velocity of the air be, uniformly, equal to uu. How can one calculate the average velocity vv across the window? If not calculate, how can one even model this system? What I've found so far: Bernoulli's principle tells us that in ...
