When the cart arrives at any place that's 1.0 meter higher than where it started, its potential energy will be
(9.8) · (its mass on kilograms) Joules .
Potential Energy is given by the formula mass x gravity x height. The starting height is irrelevant in its calculation. The potential energy depends on the mass of the object, gravity and the elevated height.
The potential energy of an object is calculated by the formula Potential Energy = mass x gravity x height. Whenever the height of an object increases, its potential energy will increase as well provided mass and the gravitational field (g) remain constant. Here, the starting height being 0.0 m is irrelevant to the calculation of potential energy at 1.0 m height. If the mass of the cart and the value of gravity (usually taken as 9.8 m/s2 on Earth's surface) are known, you can substitute those values into the formula to find the potential energy.
e.g. If the mass of the cart was 2 kg, the potential energy at a height of 1.0 m would be 2 kg x 9.8 m/s

x 1.0 m = 19.6 joules.

Explanation :
The resistance of the flashlight is 2.4 ohms
The current flowing in the circuit is 2.5 A
The Ohm's law gives the relation between the following quantities i.e.
Current
voltage
and resistance
Mathematically, Ohm's law can be written as :
V =I R
The voltage applied by the batteries is 6 volts.
Hence, this is the required solution.

i'm not getting more detailed than the other answer so yeah i just took the test
The slope of a position vs time graph represents the average velocity of the object. The velocity corresponds to the rate of change in the object's position over time. Further analysis reveals that the slope of a velocity vs. time graph signifies the object's acceleration.
In the context of physics, when analyzing a position versus time graph, the slope represents the object's average velocity. The slope is calculated as the rise over run. Rise is the change in position, or displacement, and run is the change in time. For example, Figure 3.9 shows the position (x(t)) versus time graph. The slopes of the tangent lines at specific times (0.25s, 0.5s, and 1s) indicate the object's velocity at the corresponding times. Therefore, the slope of a position vs time graph equals the velocity of the object.
Further analysis of a velocity versus time graph would then show that its slope represents the object's acceleration. This highlights the direct relationship between position, velocity, and acceleration in motion physics.

The density of the sample of gold whose mass is 38.6 grams and with a volume of 2 cm³ is 19300 kg/m
Density: This can be defined as the ratio of mass and velocity. The S.I unit of density is kg/m³.
The question above can be solved using the formula below
D = m/V.................... Equation 1
Where D = density of the sample of gold, m = mass of gold, V = volume of gold.
From the question,
Given: m = 38.6 g, = 0.0386 kg, V = 2 cm³ = 0.000002 m³
Substitute these values into equation 1
D = 0.0386/0.000002
D = 19300 kg/m³
Hence the density of the sample of gold is 19300 kg/m³

The sun creates energy through nuclear fusion. Kinetic energy creates heat and light.
The nuclear energy is the source of energy production on the sun, then this travels to the Earth in the form of Electromagnetic radiation and as it heats up the other bodies in solar system, it gets converted into the heat energy.
Explanation:
The sun is considered to be the ultimate source of energy for the whole solar system. The energy produced in the sun reaches all the other planets in the solar system. The sunlight is a very big source of energy for the Earth also.
The energy produced on the sun is due to the nuclear reaction due to the immense pressure and temperature. This nuclear energy from the sun travels to the other bodies in the solar system by means of the electromagnetic radiations.
The electromagnetic radiations from the sun carry the heat energy to the bodies and as they reach the target, the target is heated up due to the conversion of the energy from the sun into the heat energy.
Thus, The nuclear energy is the source of energy production on the sun, then this travels to the Earth in the form of Electromagnetic radiation and as it heats up the other bodies in solar system, it gets converted into the heat energy.
