The Winter...? I think...? Ya, it's the Winter. :)
A hiker walks 200 m west and then walks 100 m north, the
resulting magnitude is 223 m. The direction can be solve using trigo function
sin angle = opposite/ hypotenuse. Which is equal to 26.6 degree. So the
displacement and direction is 223 m 26.6 degree North of west.
Answer:
The velocity of a trip from City A to City B using the car is 50 miles per hour.
Explanation:
Given
200 mile trip by car takes 4 hours.
Distance between cities = 120 miles
Required:
What is the velocity of a trip from City A to City B?
To get the velocity of a trip from city A to B, we consider the parameter given for the car that travel 200 miles distance in 4 hours
Velocity = displacement ÷ time
Where displacement 200 miles
Time = 4 hours.
By substituton,
So, velocity= 200 miles ÷ 4 hours
Velocity = 50 miles ÷ hour
Velocity = 50 miles per hour
The velocity of a trip from City A to City B using the car is 50 miles per hour.
Answer:
They all work by the same basic principle: they fuse atoms in their cores to make heat and light. It's how a star works. ... That process of fusion releases heat and light. This process is called "stellar nucleosynthesis".
