Oh, dude, it's like this - the weight of an object is the force of gravity acting on it, which is 39.2 N in this case. Mass, on the other hand, is a measure of how much matter is in an object. So, to find the mass, you just divide the weight by the acceleration due to gravity (9.8 m/s^2), and voilà, you get the mass of the object, which is around 4 kg. Easy peasy, right?
392 56 x 7 = 392
To find 0.7 of 392, you multiply 392 by 0.7. This calculation gives you 274.4. Therefore, 0.7 of 392 is 274.4.
√392 ~= 19.799
Yes. 19.7989 is the square root of 392. But 392 is not a perfect square.
The LCM is 392.
The weight of an object is the force exerted on it due to gravity. On Earth, the weight of an object can be calculated by multiplying its mass by the acceleration due to gravity (9.8 m/s^2). Therefore, an object with a mass of 40 kg would weigh approximately 392 N on Earth.
There are six factor pairs: 392 = 1 x 392 392 = 2 x 196 392 = 4 x 98 392 = 7 x 56 392 = 8 x 49 392 = 14 x 28
392 56 x 7 = 392
To find 0.7 of 392, you multiply 392 by 0.7. This calculation gives you 274.4. Therefore, 0.7 of 392 is 274.4.
What planet are you on? I don't mean to be a wise-ass, but weight depends upon the acceleration of gravity, which is different on different planets, whereas mass is the same no matter where you are. On the surface of the Earth, the acceleration due to gravity is 9.8 m/s2, so a 40-kg mass will weigh 40 x 9.8 = 392 newtons.
√392 = ~19.8

392^3 = 60,236,288.
Yes. 19.7989 is the square root of 392. But 392 is not a perfect square.
The LCM is 392.
If the mass of the barrel is 40 kilograms and the barrel is presently on earth, then it weighs 392 newtons (88.2 pounds). What you do with it, what dizzying gyrations you subject it to, or what other objects happen to be nearby, have no effect on its weight.
