A 1 kg water balloon falls downward and experiences a 4.9 N air resistance as it approaches the ground. What is the acceleration of the water balloon when it experiences this air resistance?
A 1.5 kg block is pulled across a horizontal surface that has a coefficient of kinetic friction of 0.60. What is the acceleration of the block?
5 A pendulum of mass 200 g is pulled horizontally sideways by 30 cm. The length of the pendulum string is in this position assume g = 9.8N/kg 50cm 30cm b Calculate the maximum velocity that the pendulum falls with from this position.
A sample of gas has a pressure of .87atm at 25 ˚C. What is its pressure when the temperature is increased to 50˚C?
Answer the question to the scenario below. What would you do if you were in this situation? Explain what you would do and why? Be detailed. You are trying to help a person who does not speak the same language that you do. How can you get their consent or figure out what is wrong? I notice that we have a wide variety of individuals in our class, give your personal input, not what you think I want to hear.
a given mass of a gas at - 73°C exerts pressure of 40 cm of mercury. what pressure will be exerted at 127 °C if the volume remains constant
The pilot of a plane measures an air velocity of 45.8 m/s south relative to the plane. An observer on the ground sees the plane pass overhead at a velocity of 40.3 m/s toward the north. What is the velocity of the wind that is affecting the plane relative to the observer?a) 5.6 m/s to the northb) 5.6 m/s to the southc) 45.8 m/s to the northd) 86.1 m/s to the south
