The net force on the box parallel to the plane is
∑ F[para] = mg sin(24°) = ma
where mg is the weight of the box, so mg sin(24°) is the magnitude of the component of its weight acting parallel to the surface, and a is the box's acceleration.
Solve for a :
g sin(24°) = a ≈ 3.99 m/s²
The box starts at rest, so after 7.0 s it attains a speed of
(3.99 m/s²) (7.0 s) ≈ 28 m/s
Answer:
The process of evaporative cooling helps the body is explained below in complete details.
Explanation:
Your body performs the application of the evaporative process when secreting. Sweat, which contains 90 percent water, commences evaporating. ... This appears in a cooling impression (described as evaporative cooling) that serves to sustain body temperature and cools the body down when it becomes too hot.
answer : p.d = 23.6 x 5.9 =139.14
Explanation:
p.d = I x r

Answer: 1.91 hours or 1 hour and 55 minutes
Procedure:
Average speed = distance / time
=> time = distance / average speed
=> distance = 1800 km / 940 km/h = 1.91 hours
0.91 hours * 60 min / hour = 54.9 min = 55 min
=> 1 hour and 55 min.
