Vector quantity is defined by direction as well as magnitude both
so now lets discuss all option
1) distance = it is total path length between two points so there is no direction needed in it so it is scalar
2) Speed = it is ratio of total distance covered and total time, so it also do not require any direction.
<em>3)velocity = it is ratio of displacement and time, and displacement is always given with direction so velocity is a vector quantity</em>
4) time = time is the measurement of the interval of two events and we do not require any direction in it so its a scalar quantity.
Technically friction is acting on the car because it is still rubbing against the street and gravity is pulling the car down preventing it from floating??? lol
Answer:
The power to maintain constant temperature is 18.56kW
Explanation:
Given
Required
Determine the power to maintain constant temperature
The power to maintain a constant temperature is the difference between heat loss and gain
i.e.
This gives:
Convert Btu/h to kW
So:
<em>Hence;</em>
<em>The power to maintain constant temperature is 18.56kW</em>
Answer:
aerodynamics
Explanation:
if an object like a car is going 200 mph at max speed and then the car gets aerodynamic or smoothed to the point that air can get by the car it could end up going another 20 mph faster
