The formula for average speed is,
S= Total Distance Covered / Total Time Taken
In the given problem,
The total distance covered is 162 miles.
Since only the times are given, we have to determine how many hours did the car traveled from 7:30am to 10:30am.
To get the number of hours: First, subtract the hours, then the minutes. Hours: 10-7=3
Minutes: 30-30=0
Therefore,
S = 162miles/3hrs
S = 54miles/hr
The average speed of the car is 54miles/hr.
Answer:
The speed is the same as long as the reflection is regular.
Explanation:
This is because in regular reflection, the angle of incidence is equal to the angle of reflection in accordance with the second law of reflection.
Since speed of light depends on the angle of the light ray it makes with the reflecting surface, the speed is the same
Answer:
Bile helps in the digestion of fats
answer:
yes
explanation:
At a separation of the surface of Earth (r=6400km) gravity wants pull the test mass closer and closer. ... So the work done by gravity is NEGATIVE. The gravitational potential energy is negative because us trying to do the opposite of what gravity wants needs positive energy.
