<h3>I would say FALSE because you would want to try with new equipment so its not alsready worn out and best fits you. </h3><h3>Hope I helped, sorry if not tho</h3>
<span>jogs
north for exactly 5.0 min at an average speed of 8.0 km/h.
Convert velocity from km/h to km/min
V = 8.0 km/h * 1h/60min = 2/15 km/min
Distance = V*t = [2/15 km/min]*5min = 2/3 km
He continues
north at a speed of 12.0 km/h for the next 30.0 min.
Again convert km/h to km/min
V = 12.0 km/h * 1h/60min = 1/5 km/min
D = V*t = [1/5 km/min]*30min = 6 km
He then turns
around and jogs south at a speed of 15.0 km/h for 15.0 min.
Position before turning around
X = 2/3 km + 6 km = 20/3 km North
D = V*t = 15.0 km/h *(1/4 h) = 15/4 km
New position: 20/3 km North - 15/4 km South = 35/12 km North
Then he jogs
south for another 20.0 min at 8.0 km/h.
D = V*t = 8.0km/h * [1/3 h] = 8/3 km
New position 35/12 km North - 8/3 km South = 3/12 = 1/4 km North
Total distance jooged = 20/3 km + 15/4 + 8/3 km = 157/12 km = 13.08 km ≈ 13.1 km
He walks the rest of the way
home
He will have to walk 1/4 km = 0.25 km to get home after he finishes jogging

Answer:
I_total = L² (m + M / 3)
Explanation:
The moment of inertia is defined by
I = ∫ r² dm
It is appreciated that it is a scalar quantity, for which it is additive, in this case the system is formed by two bodies and the moment of inertia must be the sum of each moment of inertia with respect to the same axis of rotation.
The moment of inertia of a bar with respect to an axis that passes through ends is
I_bar = 1/3 M L²
The moment of inertia of a particle is
I_part = m x²
We have to assume the point where the particle sticks to the bar, suppose it sticks to the end
x = L
Total moment of inertia is the sum of these two moments of inertia
I_total = I_bar + I_particule
I_total = 1/3 M L² + m L²
I_total = L² (m + M / 3)
Water will boil faster at a higher elevation. Air pressure<span> affects the </span>temperature<span> at which </span>water boils quickly but cooking <span>times will take longer at higher </span>altitudes. This is due to a decrease in atmospheric pressure. An example would be putting an egg to boil. Water boils at lower temperature but the egg <span> involves heating a food to a certain temperature, so, cooking would take longer. </span>
Answer:
400 J
Explanation:
The efficiency of a machine is defined as
where
is the work output
is the work input
For this machine, we know the following
is the work in input
is the efficiency
Solving for the work output, we find
