Answer:
Fossil fuels take millions of years to replenish
Horn
Explanation:
Glaciers are powerful erosion forces as the occur. Erosion is the removal of products of weathering on the earth surface. Some of the feature of glacier erosion are:
- Glacial horns
- striations
- cirques
- glacial horns
- arêtes
- U-shaped valley e.t.c
Glaciers erode when they expand or slowly move during period of lower temperatures.
Glacier horns forms when glaciers eroded the sides of a peak leaving a sharp pointed structure behind.

Answer:
D. Opening the front door in winter to filter and clean warm ai
Explanation:
All of the following are examples of ways to improve energy efficiency of heating systems, except _______.
A. Closing off rooms that aren’t in use.
B. Frequently cleaning the furnace filter.
C. Fixing cracks in the walls and floor.
D. Opening the front door in winter to filter and clean warm air
for an heating systems it is better to keep the front door shut so that all the heat energy does not escape outside.
when heat energy is within a closed system ,it can still be utilized to keep the inhabitants warm otherwise there will be an exchange with the cold from winter fall outside the air, and the heating system's efficiency will be reduced
Answer:
7.2 V
Explanation:
The three batteries are connected in series to the terminals of the phone: it means that they are connected along the same branch, so the current flowing through them is the same.
This also means that the potential difference across the phone will be equal to the sum of the voltages provided by each battery.
Here, the voltage provided by each battery is
V = 2.4 V
So, the overall voltage will be
V = 2.4 V + 2.4 V + 2.4 V = 7.2 V
Answer:
3.75 hours
Explanation:
By 
where v is the velocity (or speed in this case)
d is the distance travelled
t is the time taken
Therefore it takes 3.75 hours for the bus to travel 150 km and 40 km/hr.
