User: 5. What is the force of gravity on a dog in a space suit that's running around on the moon? The dog's body has a mass of 20 kilograms. Round to the neares
hundredth place.
O A. 32.67 N
O B. 196 N
O C. 1,176 N
O D. 2N

Weegy: The force of gravity on a dog in a spacesuit that's running around on the moon is 32.67 N. The dog's body has a mass of 20 kilograms.
Solution: F =ma; F = (20 kg)(1.625m/s ); F = 32.5 kg.m/s? or in SI units 32.67 N.
User: 6. The force of gravity acting on a child's mass on earth is 490 newtons. What's the child's mass?
O A. 50 kg
O B. 206 kg
O C. 800 kg
O D. 4,802 kg
Weegy: Force = mass *acceleration , Child's mass = f/a = 490/ 9.8 = 50kg.
User: 6. The force of gravity acting on a child's mass on earth is 490 newtons. What's the child's mass?
O A. 50 kg
O B. 206 kg
O C. 800 kg
O D. 4,802 kg
Weegy: Force = mass *acceleration , Child's mass = f/a = 490/ 9.8 = 50kg.
User: 7. If a man has a mass of 83 kilograms on earth, what will the force of gravity on his body be on the moon?
O A. 135.6 N
O B. 813 4 N
O C. 4.880.4 N
O D. 318.5 N
Weegy: If a man has a mass of 83 kilograms on Earth, the force of gravity on his body be on the moon 135.6N.
Solution:
Force = mass x acc; 83 x 9.8 / 6 = 813.4 / 6 = 135.6N.
User: 9. The direction of the centripetal force acting on a ball on a string being spun in a circle around a person is
O A. outward-seeking.
O B. perpendicular to the person.
O C. center-seeking.
O D. parallel to the person.
Weegy: The direction of the centripetal force acting on a ball on a string being spun in a circle around a person is center-seeking.
