What is the weight of a 60 kg astronaut on Earth?

Answer: a) Weight = Fg = mg = (60 kg)*(9.8 m/s2) = 588 N. b) Given that gravity on the Moon has approximately 1/6th of the strength of gravity on Earth, a man who weighs 60kg on Earth would weigh approximately 10kg on the Moon.

What is the weight of a book?

What is a free fall class 9?

Answer. When a body or object falls towards earth due to gravitational force of earth and without any other force acting on it. It is called free. fall.

What is the weight of an object that has a mass of 20 kg in Newton?

= 20 × 1.6 = 32 N.

What will be the weight of a man on earth if his mass is 20 kg?

On the earth the weight of the body having mass 20kg will be 198N. (proved below).

What is velocity Science Grade 7?

Velocity defines the direction of the movement of the body or the object. Speed is primarily a scalar quantity. Velocity is essentially a vector quantity. It is the rate of change of distance.

What is force of gravity Class 8?

Answer: Gravitational force is the attractive force exerted by the earth on all the objects in the universe. Example of gravitational force is when a ball is thrown upwards, it falls back on the ground because of gravitational force.

What is the weight of a 40 kg object?

Answer and Explanation: Hence, the weight of the 40 kg mass is 392 N.

How can I calculate weight?

Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.

What is the weight of 65 kg person on Earth?

1) Determine the weight of a person’s mass is 65 kg, consider gravity on earth as 9.8 m/s2. Answer: In order to determine the weight of the person in the earth we only have to apply the previous formula. Where m = 65 kg and g = 9.8 m/s2. w = 637 Nw.

What is the weight of a 60 kg boy on the surface of Earth take g 10 m s2?

Weight = Fg = mg = (60 kg)*(9.8 m/s2) = 588 N.

What is the weight of paper?

The thicker the paper stock is, the higher the weight is going to be. These weights can be between 20 to 140 pounds, depending on the type of material the paper’s made from. A nice bond paper has weights between 20 and 80, while card stock, which is heavier, ranges between 50 and 140 pounds.

What do school books weigh?

Textbooks, at an average, weigh anywhere between two to six pounds (with books increasing by weight the higher the grade).

How heavy is a 500 page book?

With a size of 7 by 10 inches, a 500- page hardcover book weighs approximately 2 pounds, 10 ounces.

How heavy is 1kg example?

A small box of 100 paper clips weighs around 100 grams therefore 10 boxes would weigh 1000 grams which is equal to 1 kilogram. 1 regular-sized paper clip weighs 1 gram so you would need 1000 of them to equal 1 kilogram.

What is the weight of a 1 kg mass on the earth?

= 1 kg x 9.8m/s2=9.8 N.

What is the weight of an object of mass 1kg?

In other words, an object with a mass of 1.0 kilogram weighs approximately 9.81 newtons on the surface of the Earth, which is its mass multiplied by the gravitational field strength.

What is work class 9?

Work (W) Work is defined as a force acting upon an object to cause a displacement. It is expressed as the product of force and displacement in the direction of force. W=F x s.

What is buoyancy Class 9 short answer?

Buoyancy is the tendency of an object to float in a fluid. All liquids and gases in the presence of gravity exert an upward force known as the buoyant force on any object immersed in them. Buoyancy results from the differences in pressure acting on opposite sides of an object immersed in a static fluid.

What is acceleration due to gravity Class 7?

The acceleration of freely falling bodies due the force of attraction of the other body is called Acceleration due to gravity. It is a constant quantity for a given attracting body at a given place. Like for earth on or near its surface, the average value of acceleration due to gravity is 9.8 m/s2.

What is the weight of a body whose mass is 20kg ?( Take G 10ms 2?

Answer. Weight is equal to the mass of the object multiplied by the gravitational field strength. Gravitational field strength on Earth is nearly 10 ms-2 so the object would weigh 200 Newtons.
