if g=9.8m/s, G=6.7*10-11Nm2kg-2,calculate the mass of earth, if the radius of the earth is approximately 64m
The formula for calculating weight is given by ( W = m \times g ), where ( W ) is weight, ( m ) is mass, and ( g ) is the acceleration due to gravity. On Earth, ( g ) is approximately ( 9.81 , \text{m/s}^2 ). This formula indicates that weight is the force exerted by gravity on an object’s mass.
The object's density = (its mass) divided by (its volume)
Based on what information? A commonly used formula is force = mass x acceleration.
The formula for calculating density is as follows: density = mass/volume. Simply put, if you divide an object's mass by its volume, you will find its density. Density is the mass of an object per unit volume.
The weight of an object can be calculated using the formula ( W = m \times g ), where ( W ) represents weight, ( m ) is the mass of the object, and ( g ) is the acceleration due to gravity (approximately ( 9.81 , \text{m/s}^2 ) on Earth). This formula indicates that weight is the product of an object's mass and the gravitational force acting on it.
The formula for calculating mass is mass = density x volume. This formula relates the mass of an object to its density (amount of matter in a given volume) and volume (amount of space an object occupies).
The formula is: Mass of NaCl = mass of chlorine x 100/60,334
The formula for calculating weight is given by ( W = m \times g ), where ( W ) is weight, ( m ) is mass, and ( g ) is the acceleration due to gravity. On Earth, ( g ) is approximately ( 9.81 , \text{m/s}^2 ). This formula indicates that weight is the force exerted by gravity on an object’s mass.
The formula for calculating the mass moment of inertia of a rectangle is I (1/12) m (a2 b2), where I is the mass moment of inertia, m is the mass of the rectangle, and a and b are the dimensions of the rectangle.
The formula for calculating the inertia of a hoop is I MR2, where I is the inertia, M is the mass of the hoop, and R is the radius of the hoop.
The formula for calculating kinetic energy (KE) is KE 1/2 mass velocity2.
The formula for calculating the linear mass density of a one-dimensional object is mass divided by length. It is represented as m/L, where is the linear mass density, m is the mass of the object, and L is the length of the object.
