Answer: chicken hope this helps!
Explanation:
Answer:
W = 506.75 N
Explanation:
tension = 2300 N
Rider is towed at a constant speed means there no net force acting on the rider.
hence taking all the horizontal force and vertical force in consideration.
net horizontal force:
F cos 30° - T cos 19° = 0
F cos 30° = 2300 × cos 19°
F = 2511.12 N
net vertical force:
F sin 30° - T sin 19°- W = 0
W = F sin 30° - T sin 19°
W = 2511.12 sin 30° - 2300 sin 19°
W = 506.75 N
Using the precise speed of light in a vacuum (
), and your given distance of
, we can convert and cancel units to find the answer. The distance in m, using
, is
. Next, for the speed of light, we convert from s to min, using
, so we divide the speed of light by 60. Finally, dividing the distance between the Sun and Venus by the speed of light in km per min, we find that it is
6.405 min.
When gasoline burns in a car engine, some of the chemical energy in the gasoline is converted into heat. The heat is converted into mechanical energy. The mechanical energy moves the car or vehicle.
Hi there!
We can use the following equation for a simple pendulum:
T = Period (4.89 s)
L = length (? m)
g = acceleration due to gravity (9.8 m/s²)
Rearrange the equation to solve for L.
