If a net force of 120N gives an object an acceleration of 1.5 m s s what is the mass of the object?
Force is equal to the acceleration times mass. So, 120 N = 1.5 ((m/s)/s) times mass. So, the mass is 80 kg.
What force is necessary to accelerate a 70 kg object at rate of 4.2 m s?
Force (in newtons) is equal to the mass of the object (in kilograms) multiplied by the acceleration of the object (in meters per second per second).F = maF = 0.04 x 20F = 0.8 newtons
Does an object has the same weight regardless of its location on earth?
A 120 gram object, on the Moon, would weigh about one sixth of its Earth weight of 120 "grams weight" or "grams force". Its weight would be about 19.87 grams force on the surface of the Moon. Be careful: grams force is different from grams. 120 gram-force units is about 0.2646 pounds (1.177 newtons), which is a force from gravity, not a mass. On the surface of the Earth, a 120 gram object weighs 120 gram-force units. ================================ Observe ... A perfect example of the problems we predicted if people didn't learn the difference between mass and weight. And there you go. Read it and weep. There is NO SUCH THING as a "gram force". It's an invention, wrapped in smoke, signifying nothing, and accomplishing nothing but advanced obfuscation. The "amount of matter" in an object is its mass. It's measured in grams or kilograms, and no matter where the object is or where it goes, its mass doesn't change. The gravitational force between that object and another one ... such as the Earth, or the moon, or another planet ... depends on the mass of both objects, and on the distance between them. The forces can be expressed in newtons, pounds, stones, or other things like that. But grams are NOT a force. If you try to use grams as a force, then as soon as you leave the Earth, you're stuck. If you go to other places, then your kilogram doesn't "weigh" a kilogram anymore, and you have to make up an ugly tool like a "gram-force" to get yourself out of the jam you're in. The answer to the question is: -- A 120-gram object weighs 1.18 newtons on Earth, and 0.195 newton on the Moon. -- In "customary" units, a 120-gram object weighs 4.23 ounces on Earth, and 0.7 ounce on the Moon. -- It has 120 grams of mass everywhere. But it doesn't "weigh" 120 grams anywhere, because "gram" is not a weight, or a force of any kind.
What is the mass of a sample of a substance with a volume of 120 ml and a density of 0.75 gm?
160 grams
What is the mass no of selenium?
663.7 is the melting point of selenium.. and its true,, i promise ,, mmmwhhahahaah
What force is required to accelerate a body with a mass of 15 kilograms at an 8 meters per secound?
Since you don't tell us anything about friction or any other forces in the body's environment, we have to assume that there aren't any, and answer the question for that case. Any force, no matter how small, will accelerate any body, no matter how big. The greater the force is, the greater the acceleration will be. To find out exactly what the acceleration is, simply divide the force by the mass.
If a net force of 120N gives an object an acceleration of 1.5 m s s what is the mass of the object?
Force is equal to the acceleration times mass. So, 120 N = 1.5 ((m/s)/s) times mass. So, the mass is 80 kg.
If an object on the moon has a mass of 120 kg what is the force of gravity acting on the object on the moon?
The gravity near the Moon's surface is about 1.62 meters per second square; that's equivalent to 1.62 newton/kilogram. In other words, you need to multiply the mass by this number.
If a person weighs 120 kg on earth then what will he weigh on the moon?
kg (kilogram) is a measure of mass, not of weight. If a person has a mass of 120 kg on Earth, he will also have a mass of 120 kg on the Moon. His weight will change, his mass won't change.Mass is measured in kilograms and weight is measured in newtons..In daily life we use to say that this person having weight 120 kg but that is not correct .But in scientific language we must say that person is having a mass of 120 kg and his weightwould be calculated according to gravity of earth that is 9.8m/sec .Weight is actually the force ...so weight would beforce = acceleration * massweight = gravity * massweight =9.8 * 120=1176 newton(On earth)Gravity on moon is 1/6 of earth i.e. 9.8/6=1.64m/secAnd on moon also the mass would be 120 kg and the weight would beforce = acceleration * massweight = gravity * massweight = 1.64 * 120=196.8 newton (On Moon)As you can see the weight(force) on earth is 1176 newtonfor person having mass 120 kg and the weight(force) on moon is 196.8 newton.As the force on man on earth is 1176 newton so he would feel much more heavier.And the force on man on moon is 196.8 newton so he would feel lighter there.So the person having mass 120 kg will have more weight(force) on earth than on moon.Dont get confuse between mass and weight ...if you are 55 kg ...in daily use word we say our weight is 55 kg but that is not weight instead it's your mass and your weight is (55*9.8=539 newton) means you have mass 55 kg and weight 539 newton...if you still get problem do mail mevivianpeter2@gmail.comI m ready to help you
What is the power if a force of 500 Newton moves a mass 1000 meters in 120 seconds?
Power = Force x displacement/time = 500 x 1000 / 120 = 4166.67 W
What force is necessary to accelerate a 70 kg object at rate of 4.2 m s?
Force (in newtons) is equal to the mass of the object (in kilograms) multiplied by the acceleration of the object (in meters per second per second).F = maF = 0.04 x 20F = 0.8 newtons
If Aashma Poudel does 150 joules of work lifting a 120-newton backpack. How high did she lift the backpack?
D=1.250m.
When a baseball player hits a 120 gram baseball with a force of 200 newtons what is the acceleration of the ball?
f=ma so a=f/m a=200 newtons / 120 grams a= 1.6667 newtons/grams
If an object has a mass of 120 g on earth then on the moon it would have a mass of what?
The object would have the same mass as mass remains constant everywhere. On the other hand if it was weight it would change as weight = mass multiplied with gravitational force.
What is the mass of 120 ml of water?
The mass of 120 mL of water is 120 g.
What is the acceleration of the 25 kg crate which is pulled by a rope along a frictionless surface at an angle of 30 degrees above the horizontal if the tension on the rope is 120 N?
the force acting down the slope = sin 30 * 25 (kg) = 0.5 * 25 = 12.5 kg = (12.5 * 9.806 ) 122.575 newtons = resultant force of (122.575-120 ) 2.575 newtons downhill giving downhill acceleration of (using f=ma) 0.103 (m/s)/s
