Answer
given,
height of counter = 1.20 m
horizontal distance from base = 1.6 m
a) velocity of mug = ?
using equation of motion
t = 0.495 s
speed of the mug
s_x = v x t
1.6 = v x 0.495
v = 3.23 m/s
b) final velocity of mug in y direction
again using equation of motion
v² = u² + 2 a s
v²= 0 + 2 x 9.8 x 1.2
v = √23.52
v_y = 4.85 m/s
now, direction
Answer:
26 m southwards.
Explanation:
From a North, East, South, West coordinate plane, moving northwards implies positive distance. While moving southwards implies negative distance.
Thus;
It moves 16 meters northward; d = 16 m
It now moves 22 meters southward; d = -22 m
It moves 12 meters northward; d = 12 m
It moves 32 meters southward; d = -32 m
Thus, total magnitude = 16 - 22 + 12 - 32 = -26 m
Thus, the object travels 26 m southwards.
Answer:
when a person is not breathing
Explanation:
The electrocardiogram shows the cardiac action of the heart as a means of the sinusoidal waves. However, the waves have a different structure as they show the pumping phase, breathing and the resting phase of the heart. The waves continues to be displayed as long as there is systolic and diastolic pressure in the heart muscles. When there is no action, such as the cessation of brain activity, action ceases.
Circulation system. Blood to working muscles.
Skeleton supports movement and gives leverage
Breathing system. Need more O2 when muscles are working.
