The image below shows a model of the atom which subatomic particle does the arrow in the image below identify ?

The correct answer to the question is : C) Thermal energy.

EXPLANATION:

Before coming into any conclusion, first we have to understand thermal energy and conduction.

The thermal energy of a body is the sum total of kinetic energy and potential energy of all of its molecules or atoms.

Whenever a body at high temperature is connected to a body at low temperature, the thermal energy will flow from body at high temperature to a body at low temperature. The part of thermal energy which is transferred due to temperature difference is called heat flow. This process is called conduction where there will be no actual transport of atoms or molecules from one body to another body.

As per the question, Javior touches the hut mug of tea. The mug surface is at high temperature as compared to Javior hand. Hence, heat flow be from mug surface to hand of Javior.

Hence, the correct answer to the question is thermal energy.

Answer: 20 minutes

Explanation:

Given the following :

Average speed of train = 120km/hr

Distance = 40km.

The time take by the train moving at an average speed of 120km/hr to cover a distance of 40km due is ;

Recall:

Speed = distance / time

Therefore,

Time taken = distance covered / speed

Time taken = 40km / 120km/hr

Time taken = 1/ 3 hr

Therefore, 1/3 rd of an hour equals

1/3 × 60 = 20 minutes.

Time taken) 20 minutes

Time taken by tain to cover distance is 20 minutes as:

Distance= 40 km

Speed= 120 km/h

Time= distance/speed

= 40/120

= 1/3 hour

= 20 min

or  =0.33 hrs

Answer:

The sentence that describes the movement of matter and energy in the water cycle is:

C. Energy from sunlight warms the ocean surface and causes water to evaporate.

Explanation:

In the water cycle, energy from sunlight plays a crucial role in causing water to evaporate from the ocean surface. This evaporation process occurs when the sun's energy heats up the water, increasing its temperature. As a result, the water molecules gain enough energy to break free from the liquid state and transform into water vapor, which rises into the atmosphere. This step represents the movement of both matter (water) and energy (sunlight) in the water cycle.

Answer:

The answer to your question is: v = 121.46 m/s

Explanation:

Data

h = 30 m

vo = ?

dx = 300 m

Formula

t =

speed = distance / time

Process

t= 2.47 s

speed = 300 / 2.47

speed = v = 121.46 m/s

Answer:

15.7m/s

Explanation:

To solve this problem, we use the right motion equation.

 Here, we have been given the height through which the ball drops;

 Height of drop = 14.5m - 1.9m  = 12.6m

The right motion equation is;

      V²  = U² + 2gh

V is the final velocity

U is the initial velocity  = 0

g is the acceleration due to gravity  = 9.8m/s²

h is the height

  Now insert the parameters and solve;

       V² = 0² + 2 x 9.8 x 12.6

      V²  = 246.96

       V = √246.96  = 15.7m/s
