Answer:
I'm not taking physics right now but I would love too.
Explanation:
T = 2,548
What is tension?
Tension occurs due to the direction of pull on the object and along the length of the given rope.
It's S.I. unit is Newton
Tension formula can be represented as
T = mg + ma
T = 200 (9.8 + 1.3 m/s²)
T = 200 (12.74)
T = 2,548

We first calculate for the volume of each of the figure by dividing all together the dimensions of the rectangular prism.
Volume = (10 ft)(3 ft)(3 ft) = 90 ft³
Then, multiply the volume of each prism by 10 to get the total amount of cement that needs to be poured.
Total volume = (90 ft³)(10) = 900 ft³
In order to accelerate the dragster at a speed
, its engine must do a work equal to the increase in kinetic energy of the dragster. Since it starts from rest, the initial kinetic energy is zero, so the work done by the engine to accelerate the dragster to 100 m/s is
however, we must take into account also the fact that there is a frictional force doing work against the dragster, and the work done by the frictional force is:
and the sign is negative because the frictional force acts against the direction of motion of the dragster.
This means that the total work done by the dragster engine is equal to the work done to accelerate the dragster plus the energy lost because of the frictional force, which is
:
So, the power delivered by the engine is the total work divided by the time, t=7.30 s:
And since 1 horsepower is equal to 746 W, we can rewrite the power as
spiral galaxy
It's called a spiral galaxy because if you could view it from the top or bottom, it would look like a spinning pinwheel.
