- Bryce, a mouse lover, keeps his four pet mice in a roomy cage, where they spend much of their spare time, when they're not sleeping or eating, joyfully scampering about on the cage's floor. Bryce tracks his mice's health diligently and just now recorded their masses as 0.02450.0245 kg, 0.01470.0147 kg, 0.02390.0239 kg, and 0.01230.0123 kg. At this very instant, the x‑ and y‑components of the mice's velocities are, respectively, (0.515 m/s,−0.719 m/s), (−0.857 m/s,−0.215 m/s), (0.395 m/s,0.963 m/s), and (−0.743 m/s,0.759 m/s). Calculate the x‑ and y‑components of Bryce's mice's total momentum, px and py.An irregular shaped object has a mass of 2.945 g and a density of 3.21 g/cm^ 3 What is the object's volume?The density of aluminum is 2.7 g/cm^3. How much mass is contained in a chunk of aluminum with a volume of 379mL?
- The "classical" radius of a neutron is about 0.79 fm (1 femtometer = 10-15 m). The mass of a neutron is 1.675×10-27 kg. Assuming the neutron is sphereical, calculate its density in kilometer per cubic meterThe radius of Jupiter is about 69.0 x 103 km. The radius of the Sun is about 68.0 x 104 km. How many Jupiter volumes would fit inside the suns volume ?Calculate the mass in kilograms of a 2.14 kg object when its velocity, relative to us, is each of the following values. (Notice the progression of these numbers toward the velocity of light, 3.00 × 108 m s-1.) velocity = 2.68 × 108 m s-1 m=______ kg
- One year on Mars is as long as 1.88 years on earth. How many seconds is a Martian year? Please give the correct answerYou're designing a mission with a special type of rocket, a nuclear thermal rocket (NTR). Since it uses a nuclear reactor to heat the propellant, it can achieve an exhaust velocity of vex = 5.65 km/s. The crew's habitat space, the rocket itself, the shadow shield to protect from radiation, and the instrument payload for scientific research all have a combined mass of 607 x 103 kg, and the propellant is 3,638 x 103 kg. What is the total delta-V of the rocket in km/s?If mass Q/mass A= 0.571 in AQ, what is mass Q/mass A= in A2Q3?
