1 An astronaut has a mass of 65kg on Earth, where the gravitational field strength is 10N/kg.(a) Calculate the astronaut's weight on Earth.weight on Earth =...[2](b) Complete the following sentence.The astronaut's weight on Earth is the force.between the astronaut and-[1](c)The...
Calculating Earth's Mass Assume that Earth is one of the masses (M1) and a 1-kg sphere is the other (M2). The force between them is 9.8 kg x m/s2— we can calculate this force by dropping the 1-kilogram sphere and measuring the acceleration that the Earth's gravitational field appli...
- G is the gravitational constant, approximately 6.674×10−11N m2/kg2,- m1 is the mass of the first object (Sun),- m2 is the mass of the second object (Earth),- r is the distance between the centers of the two objects. 1. Identify the values: - Mass of the Sun, m1=2×10...
如图所示是同一个宇航员在地球和月球上的称重比较,下列针对图文信息的说法不正确的是Earth Moon Mass=60 kg Mass=60 kg Weight=588 N Weight=98 N A. m地=m月,因为质量不随物体的位置改变而改变 B. m地=m月,因为质量是物体的属性 C. G地>G月,因为重力与物体的位置有关 D. G地>G月,因为宇航员的...
9 (a) A satellite orbits the Earth of mass M in a circular path of radius r.(i) Show that the period T of the satellite is given by the expression T^2=(4π^2)/(GM)r^3 [3](ii) A satellite is orbiting the Earth above the equator with a period of 28 hours. The mass of ...
A 1.0kg mass weighs 9.8n on Earth's surface, and the radius of the Earth is roughly 6.4x10^6m. What is the mass of the Earth and the average density of Earth? An object weighs 10 N on Earth. What will be its weight on a planet whose mass is 1/2 that of the Earth and whose...
Your mass on the earth and the moon are identical. Your weight on the moon is about one-sixth of your weight on the earth. Rest Mass To be more precise about mass, we need to mention the concept of rest mass, also known as intrinsic mass. It is actually an object's rest mass that...
- G is the gravitational constant (6.67×10−11Nm2/kg2),- m1 is the mass of the Earth (6×1024kg),- m2 is the mass of the Moon (7.4×1022kg),- r is the distance between the Earth and the Moon. Step 1: Write down the formula for potential energy U=−G⋅m1⋅m2r Step...
Calculate the average force exerted by the Sun on the Earth. View Solution Q4 The mass of the earth is 6×1024 Kg. The distance between the earth and the sun is 1.5×1011 m. If the gravitational force between the two is 3.5×102 N, What is the mass of the sun ? View Solu...
Answer to: Calculate the force of gravity on a 2 kg mass at Earth's surface. The mass of Earth is 6 * 10 ^{24} kg, and its radius is 6.4 * 10 ^6...
