Answer:

Height above a surface

Explanation:

Gravitational potential energy is the energy which an object possesses due to its position above a surface.

It is also the amount of work a force has to do in order to bring an object from a particular position to a point of reference.

It is given mathematically as:

P. E. = m*g*h

where m = mass of the body

g = acceleration due to gravity

h = height above a surface

m*g represents the weight of the object.

Hence, Gravitational potential energy is the product of an object's weight and its height above a surface/reference point.

A minimum temperature thermometer in a standard weather instrument shelter measures an overnight low temperature of 36 degrees F
Rudiy27

Answer:

Explanation:

Even though the minimum temperature is more than the freezing point, Frost was observed on the ground because the ground will cool rapidly as cool air tends to move towards the ground, the temperature of the ground is lower than the atmosphere a few feet above it.

As the thermometer is kept some feet above the ground so ground temperature may be lower than the minimum recorded temperature.

For each of the situations described below, the object considered is undergoing some changes. Among the possible changes you sho
velikii [3]

Answer: a. (Q), (T), (E)

              b. (Q), (T), (E), (W)

Explanation: <u>Thermal</u> <u>Energy</u> and Temperature are closely related: when the temperature rises causing atoms or molecules to move, thermal energy is produced. Thermal energy is the energy within the system.

<u>Mechanical</u> <u>Work</u> is the amount of energy transferred due to an applied force.

<u>Chemical</u> <u>Energy</u> is the energy contained in the bonds of chemical structures of the molecules released when a chemical reaction happens.

Given the explanations, let's analyse the situations:

a. For an ice cube to be melting, it has to be absorbing heat, which means its thermal energy is changing and, consequently, so does its temperature;

b. First, the gas inside the cylinder reaches a thermal equilibrium, which means its thermal energy and temperature changed. Since there were  exchange of heat to reach the equilibrium, the gas absorbed or gave off heat. After the equilibrium, when the piston starts to be moved, the energy of the pressure is transferred to the gas, so mechanical work had been done.

A jetliner rolls down the runway with constant acceleration from rest, it reaches its take off speed of 250 km/h in 1 min. What
nlexa [21]

Answer:

Acceleration, a=14970.05\ km/h^2

Explanation:

Given that,

Initially, the jetliner is at rest, u = 0

Final speed of the jetliner, v = 250 km/h

Time taken, t = 1 min = 0.0167 h

We need to find the acceleration of the jetliner. The mathematical expression for the acceleration is given by :

a=\dfrac{v-u}{t}

a=\dfrac{250}{0.0167}

a=14970.05\ km/h^2

So, the acceleration of the jetliner is 14970.05\ km/h^2. Hence, this is the required solution.
