Force = mass x acceleration

f=ma

since on earth a=g =9.81 m/s²

therefore

f= 784 N = m x 9.81

m = 784/9.81 = 79.918 kg

What is the weight of the astronaut on earth What is the weight of the astronaut on the moon?

The weight of an astronaut on Earth is determined by their mass multiplied by the gravitational acceleration of Earth, which is approximately 9.81 m/s². For example, if an astronaut has a mass of 80 kg, their weight on Earth would be about 784 Newtons (N). On the Moon, the gravitational acceleration is about 1.62 m/s², so the same astronaut would weigh approximately 129.6 N on the Moon. Thus, the astronaut's weight decreases significantly when on the Moon due to the lower gravitational pull.


What would a 70 pound weigh on the moon?

Depends on the dog! A great dane would still be heavy even on the Moon, while a "minpin" would be even lighter than here on Earth.Because of the Moon's smaller size and lower density, the force of gravity is about 1/6th that of Earth.


How many monsters and aliens have been on Dr. Who?

I really do not suggest counting. There have been 224 stories and 784 individual episodes aired. There is a different monster or alien in most of these stories - though there are exceptions such as Daleks and Cybermen which star in many. Regardless, there must be over 100 - probably over 150 - so DON'T COUNT... You will regret it...

Tobias has a weight of 784 N What is his mass?

To find Tobias's mass, we use the formula: weight = mass x gravity. Given that the weight is 784 N and assuming gravity is approximately 9.81 m/s^2, we can rearrange the formula to find mass: mass = weight / gravity. Therefore, Tobias's mass is approximately 80 kg.


Weight can be described as what?

Weight is a force acting on a smaller mass due to a gravitational interaction with a larger mass. The weight of an 80 kg human on a 5.974*10^24 kg planet with a radius of 6378 km (this is earth) is equal to 784 Newtons (or 176 lbs).

How much does 80 kg weight?

On earth it is 784 newtons or 176 lbs.


Why does an object on the moon weigh less than it does on earth even though its mass does not change?

Your mass is a measure of how much matter you're made up out of. That does not change if you go to the moon (or elsewhere). Your weight is the product of your mass AND the mass of the planet (body) you're standing on ---- divided by the distance between the two --- and the moon masses much less than the Earth. Another way of putting this is your weight is your mass multiplied by the gravitational pull, so Weight = Mass x Gravitational Pull Now, considering that the gravity of an object depends on its mass, and as said before, the Earth's mass is far greater than the moon's, the gravitation pull of the Earth (Equal to roughly 9.8 N/kg) is greater than that of the moon (Roughly 1.6 N/kg) So say someone's mass is 80kg, their weight (on Earth would be) Weight = 80 x 9.8 This means their weight is 784 Newtons on Earth, where as on the moon their would weigh Weight = 80 x 1.6 And they would weigh 128N. Hope this helps.
