Since this is a distance/time graph, the speed at any time is the slope
of the part of the graph that's directly over that time on the x-axis.
At time t1 = 2.0 s
That's in the middle of the first segment of the graph,
that extends from zero to 3 seconds.
Its slope is 7/3 . v1 = 7/3 m/s .
At time t2 = 4.0 s
That's in the middle of the horizontal part of the graph
that runs from 3 to 6 seconds.
Its slope is zero.
v2 = zero .
At time t3 = 13 s.
That's in the middle of the part of the graph that's sloping down,
between 11 and 16 seconds.
Its slope is -3/5 . v3 = -0.6 m/s .
Answer:
After one half of the battery's useful life.
Explanation:
Batteries of the emergency locator transmitter (ELT) must be replaced or recharged after one half of the battery's useful life because if it is exposed to the high temperature for a long period of time such as the air plane parked in the sun will result in the deterioration of battery which may makes the transmitter out of order before the expiry date of the battery. So it will be safe to do that after the use of one half of the battery's life.
Answer:
The maximum load that this person is able to lift is 34.3 N
Explanation:
Applying the balancing torque, the expression is equal:
F₁L₁ = F₂L₂
Where
g = 9.8 m/s² = gravity
L₁ = 0.8 m
F₂ = 527 N
L₂ = 6 - 0.8 = 5.2 m
Replacing and clearing the mass m:
The maximum load that this person is able to lift is:
F = m * g = 3.5 * 9.8 = 34.3 N
Answer:
If the scale is 1 : x, then divide the actual distance by x to calculate the map distance.
