In mechanics, the normal force<span> is the component, perpendicular to the surface (surface being a plane) of contact, of the contact </span>force<span> exerted on an object . We calculate as follows:
</span>∑F along x = 0 = F - Fn
<span>
Fn = F = mg = 7.52(9.81) = 73.77 N <------OPTION B</span>
Answer:
Explanation:
acceleration is the time rate of change of velocity
a = (51 - 20) / 3 = 10⅓ mi/hr/s
which should probably be converted to standard units.
10⅓ mi/hr/s(5280 ft/mi) / 3600 s/hr) = 15.15555... ≈ 15.2 ft/s²
which is roughly half the acceleration of gravity.
Answer:
Option (D), lunar eclipse
Explanation:
When the moon comes between the earth and sun, the lunar eclipse occurs, so D is the lunar eclipse. It is full moon day.
C is the position when there is new moon day and it is solar eclipse.
So, option (D) is correct.
True. The answers to the blanks are slow down, decrease, and contract (in the given order). Molecules move faster when warmer so, because it was cold the molecules in the air slowed down which lessened the kinetic energy and the overall volume of the tires to seem less nd more contracted.
