The snapshot of light as the cart moves with constant velocity is represented by a graph with uniform displacement at each time interval.
The change in displacement with time is uniform at constant velocity. The displacement of the supplied moving item grows at the same pace.
The beginning velocity equals the ultimate velocity at constant velocity.
v₁ = v₂
The object's acceleration at constant velocity is zero since the velocity change with time is zero.
As a result, we may deduce that the graph with equal displacement at each time interval reflects a snapshot of light as the cart moves at a constant speed.
A moving object's displacement-time graph shows the distance traveled by a moving item as time passes. A vector quantity is displacement. The slope or gradient of this graph represents the velocity of the item. The displacement-time graph, also known as the position-time graph, describes an object's motion. In this graph, the displacement of the moving item is displayed on the y-axis as a dependent variable, while time is shown on the x-axis as an independent variable.

Answer:
<h3>The answer is 500 km </h3>
Explanation:
The distance covered by an object given it's velocity and time taken can be found by using the formula
<h3>distance = average velocity × time</h3>
From the question
average speed = 250 km/h
time = 2 hrs
We have
distance = 250 × 2
We have the final answer as
<h3>500 km</h3>

Answer:
5.3 hours
Explanation:
(3180 km) / (600 km/h) = 5.3 hours
the amount of heat need is 71060 Joules
ExplanationThe equation for the amount of heat needed to increase the temperature of water is as follows:
where E is the amount of heat
C is the specific heat capacity of water having a standard value of 4180 J/kg*K
T is the final ans initial temperature in kelvin
m is the mass
so
Step 1
given
a) convert the temperature into kelvin
now, replace in the formula
therefore, the amount of heat need is 71060 Joules
