A blinking light of constant period is situated on a lab cart. Which diagram best represents a photograph of light, taken every
Karo-lina-s [1.5K]

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.

PLS HELP BEING TIMED!!!
Elodia [21]

Answer:

K_{i}+U_{g,i} = K_{f}+U_{g,f}

Explanation:

A closed system is a system where exists energy interactions with surroundings, but not mass interactions. If we neglect any energy interactions from boundary work, heat, electricity, magnetism and nuclear phenomena and assume that process occurs at steady state and all effects from non-conservative forces can be neglected, then the equation of energy conservation is reduce to this form:

\Delta K +\Delta U_{g} = 0 (1)

Where:

\Delta K - Change in kinetic energy of the system, measured in joules.

\Delta U_{g} - Change in gravitational potential energy of the system, measured in joules.

If we know that \Delta K=K_{i}-K_{f} and \Delta U_{g} = U_{g,i}-U_{g,f}, then we get the following equation:

K_{i}+U_{g,i} = K_{f}+U_{g,f} (2)

Where i and f stands for initial and final states of each energy component.

Hence, the right answer is K_{i}+U_{g,i} = K_{f}+U_{g,f}

If earth did not rotate how would air at the equator move?
Dmitry_Shevchenko [17]
Heat rises, and it is warmer at the equator, so I think warm air would rise at the equator and move towards the cooler poles.
