Answer:
104 times by 3.3
Explanation:
104 is the distance for 1 hour. So you need to multiply it by 3.3( because it's 3 hour and 30 minutes)
Answer:
Part a)
Part b)
Part c)
Part 4)
angular acceleration will be ZERO
Part 5)
Explanation:
Part a)
Moment of inertia of the system about left end of the rod is given as
So we have
Part b)
If force is applied to the mid point of the rod
so the torque on the rod is given as
now angular acceleration is given as
Part c)
position of center of mass of rod and sphere is given from the center of the sphere as
so moment of inertia about this position is given as
so we have
Part 4)
If force is applied parallel to the length of rod
then we have
so angular acceleration will be ZERO
Part 5)
moment of inertia about right edge of the sphere is given as
so we have
Cool down the Slowest
B. Seawater, because it heats up slower and gives away heat slower than sand.
Read the question wrong the first time
Answer:
Explanation:
The conversion factor on earth is 15200 / 200 = g
g = 78 but it certainly cannot be in m/sec^2. The question does not seem to be correct.
To continue, the mass on the moon is 200 kg. It would be the same on Mars or Jupiter or anywhere in the universe.
If g is 1/6 the value on the moon as on earth then
g_moon = 78 *(1/6)
g_moon = 13 and again, I cannot specify the units.
Answer: 1666J
Explanation:
Given that,
Mass of box (m) = 10kg
Total distance covered by box (h)
= (5m + 12m)
= 17m
work done on the box = ?
Work is done when force is applied on an object over a distance. Hence, the magnitude of work done on the box depends on its mass (m), distance covered (h), and acceleration due to gravity (g)
(g has a value of 9.8m/s²
i.e Work = mgh
Work = 10kg x 9.8m/s² x 17m
Work = 1666J
Thus, 1666 joules of work was done by the woman on the box.
