Answer:
500 N
Explanation:
Natural bouyency will keep the diver in the same place, no matter what the mass of gfs. This means if the diver is displacing with a weight of 500 N, the upthrust will also be 500 N.
Answer:
Average force exerted on car = 250,000 N or 250 KN
Explanation:
Given:
Initial speed u = 20 m/s
Final speed v = 0 m/s
Total distance covered = 1.2 m
Find:
Average force exerted on car
Computation:
v² = u² + 2as
0² = 20² + 2(a)(1.2)
a = -166.67 m/s² or 166.67 m/s²
Average force exerted on car = Ma
Average force exerted on car = (1,500)(166.67)
Average force exerted on car = 250,000 N or 250 KN
Weight = (mass) x (gravity)
From this simple formula for weight, you can see that
an object's weight is directly proportional to the acceleration
of gravity in the place where the object is located.
If the object weighs 350 N on Earth and 134 N on Mars, then
we can write
(9.8 m/s²) / 350 = (Mars gravity) / 134
Multiply each side by 134:
Mars gravity = (134/350) x (9.8 m/s²)
Mars gravity = 3.75 m/s²
(The official, accepted value is 3.71 m/s² .)
