Answer:
190.3759 pounds
Explanation:
If the astronaut weighs 210 pounds when he is at a distance of 3978 miles from the Earth's center, then he will weigh
210 [3978 / (3978 + 200) ]² = 190.3759 pounds
at an altitude of 200 km.
Sunspot. Sunspots are temporary cooler areas on the Sun's surface caused by changes in its magnetic field.
Answer:
12.5J
Explanation:
Given parameters:
Mass of bucket = 1.7kg
Height = 75cm = 0.75m
Unknown;
Work done on the bucket by the person = ?
Solution:
To solve this problem, we use the work done equation;
Work done = force x distance = mgh
m is the mass
g is the acceleration due to gravity
h is the height
Now, insert parameters and solve ;
Work done = 1.7 x 9.8 x 0.75 = 12.5J
