You can use 10 when you only need a rough answer. Use 9.8 when you want your
answer to be more accurate, and if you want it still more accurate, then look up a
more accurate number for the acceleraiton of gravity. (9.8 is a rounded figure.)
The mass of an object can be calculated using the formula: mass = weight/gravity. In this case, if the weight is 98 N and gravity is approximately 9.81 m/s^2 on Earth, the mass would be approximately 10 kg.
The velocity of an object in free fall after 10 seconds is approximately 98 m/s. This value is the acceleration due to gravity (9.8 m/s^2) multiplied by the time in seconds.
Near Earth's surface, it would weigh about 98 newton.Weight = mass x gravity And, close to Earth, the gravitational field ("gravity") is about 9.8 newton/kilogram.
The weight of the ball is the force exerted on it due to gravity. Using the formula weight = mass x acceleration due to gravity, the weight of a 10 kilogram ball with an acceleration due to gravity of 9.8 m/s^2 is 98 Newtons.
9.8 meters/second2 x 10 seconds = 98 meters/second.

Force = mass X gravity therefore, 10 X 9.8 = 98 N ==================== -- Assuming that this is all happening near the earth, the 10 kg mass weighs 98 newtons. That means the force of gravity on it is 98 newtons, pointing straight down. -- Since it's just hanging there motionless and not accelerating either up or down, the net vertical force on it must be zero. -- The only other force on it besides gravity is the tension in the rope. -- In order for all the vertical forces on it to add up to zero, the tension in the rope must be exactly equal and opposite to the force of gravity ... 98 newtons pointing straight up.
what is the value of a Winchester carbine 1912 that is 98 years old
98 x 10 = 980
9.8
The weight of the ball is the force exerted on it due to gravity. Using the formula weight = mass x acceleration due to gravity, the weight of a 10 kilogram ball with an acceleration due to gravity of 9.8 m/s^2 is 98 Newtons.
It is 7(10+4) = 98
10 times 98 of anything is 980 of them.
The postage from the US for an ordinary first class letter of 1 ounce or less is 98 cents You can buy a 98-cent stamps or use any combination of stamps whose total value is 98 cents of more. 2 forever stamps plus a 10-cent stamp would work.
