Response:
AB = 100 km; BC = 80 km; AC = 180 km
Time of arrival = 11:30
Reasoning:
1. Distance from A to B
(a) Duration of travel
Duration = 10:00 - 8:00 = 2.00 hours
(b) Distance
Distance = speed × time = 50 km/h × 2.00 h = 100 km
2. Distance from B to C
Distance = 80 km/h × 1 h = 80 km
3. Summary of Distances
AB = 100 km
BC = 80 km
AC = 180 km
4. Time of Arrival
Departure from A = 08:00
Travel duration to B = 2:00
Arrival at B = 10:00
Waiting time at B = 0:30
Departure from B = 10:30
Travel duration to C = 1:00
Arrival at C = 11:30
Response:
0.9 cm
Clarification:
The following illustrates the calculation of the combined rod's length increase:
As established
Length increase = expansion of aluminum rod + expansion of steel rod
= 0.9 cm
We simply summed the expansions of both the aluminum and steel rods to determine the overall increase in the joined rod's length, which must be factored in
The answer is
-Small f and large D.
The explanation:
-A car jack acts as a machine, defined as an apparatus that aids individuals in exerting force more easily.
-Hence, by applying a small force to the jack, the height at which the car is elevated increases.
Machines are essential for people to amplify their strength; without them, lifting a car would be impossible.
Employing leverage or hydraulic principles, machines enhance your exerted force.
Utilizing a greater lever allows for extensive movement with minimal force, resulting in the opposite side moving shorter distances with an increased force.
