Answer:
Acceleration
When we cross multiply, distance will be equal to acceleration multiply by time
Distance = acceleration x time
Distance = 9.8 x 3
= 29.4 m/s
Wending your way through this question and the list of choices
is like running through a corn-maze on a moonless night with
your eyes closed.
Work = (force) x (distance)
Keeping with the units used In the question ...
Work = (90 pounds) x (4 feet) = 360 foot-pounds .
If you want the work expressed in joules, then you need to convert
pounds and feet to newtons and meters.
(90 pounds) x (4.448 newtons/pound) = 400.32 Newtons
(4 feet) x (1 meter / 3.28084 feet) = 1.219 meters
Work = (force) x (distance)
= (400.32 newtons) x (1.219 meters) = 488.1 joules .
They are formed when a metal loses electrons and when a nonmetal gains those lost electrons.
Answer:
pulse = force * time
force = mg = 0.1kg * 10 = 1 N
time = 0.5
pulse = 0.5 f.s
