Defintion: Weight. The gravitational force on a mass is its weight. We can write this in vector form, where w → is weight and m is mass, as. (6.5.1) w → = m g →. In scalar form, we can write. (6.5.2) w = m g. Since g = 9.80 m/s 2 on Earth, the weight of a 1.00-kg object on Earth is 9.80 N:

Key points The terms weight and mass are often wrongly used to describe the same thing. In science, weight and mass are very different. Weight versus mass The terms weight and mass are.

September 6, 2022 Uncategorized In tabular form, the difference between mass and weight is given. They have detailed comparisons of the mass and weight. Mass and weight are both used interchangeably, but they are not. Your weight changes from place to place, no matter where you go in the universe.

A block of mass 4 kg is pulled along a smooth inclined plane of inclination 30∘ with constant velocity 3 m/s as shown, power delivered by the force is ADVERTISEMENT Text Solution A 40 watt B 20 wall C 60 watt D 30 watt Answer The correct Answer is C Answer

NCERT Question 10 (Method 1) An object of mass 40 kg is raised to a height of 5 m above the ground. What is its potential energy? If the object is allowed to fall, find its kinetic energy when it is half-way down.At Height = 5 mMass of the object = 40 kgHeight of the object = 5 mAcceleration

First, you can calculate the molar mass of FeCl2 by adding the molar masses of Fe (55.845 g/mol) and 2 atoms of Cl (2 times (35.446 g/mol). This gives a molar mass of 126.737 g/mol. Since each mole is 126.737 grams, you multiply 3.5 mols by 126.737 grams, giving you 443.58 grams.

Chemistry 1 Answer Junaid Mirza Apr 23, 2018 0.1 L Explanation: Molar mass of NaOH = 40 g/mol Moles of NaOH = 0.40 g 40 g/mol = 0.01 mol Molarity = Moles of solute Volume of solution (in litres) 0.100 M = 0.01 mol V V = 0.01 mol 0.100 M = 0.1 L Answer link

Type your height and weight into the online BMI calculator from NIH. Your body is made up of water, fat, protein, carbohydrate and various vitamins and minerals. If you have too much fat — especially if a lot of it is at your waist — you're at higher risk for such health problems as high blood pressure, high blood cholesterol and diabetes.

The mass number (represented by the letter A) is defined as the total number of protons and neutrons in an atom. Consider the table below, which shows data from the first six elements of the periodic table. Consider the element helium. Its atomic number is 2, so it has two protons in its nucleus.
