Answer from: shimohsen

Tension, T = 74.82 N

Explanation:

It is given that,

Angle between the suitcase and horizontal, $\theta=36^{\circ}$

Work done, W = 908 J (let)

Distance covered, d = 15 m (let)

We know that the work done by an object is given by the formula as :

$W=Fd\ cos\theta$

here, F = T

$W=Td\ cos\theta$

$T=\dfrac{W}{d\ cos\theta}$

$T=\dfrac{908}{15\times cos(36)}$

T = 74.82 N

So, the tension in the strap is 74.82 N. Hence, this is the required solution.

74.79N

Explanation:

The question is incomplete. Here is the complete question.

" A traveler pulls on a suitcase straps at an angle 36° above the horizontal. If 908J of work are done by the strap while moving the suitcase a a horizontal distance of 15m, what is the tension in the strap?"

Work is said to be done if an applied force cause an object to move through a distance.

Work done = Force F × perpendicular distance d

Since the strap is pulled at ana angle above the horizontal,

Work done = F ×d cos(theta)

Given workdone = 908Joules

d = 15m

theta = 36°

908 = F × 15cos36°

F = 908/15cos36°

F = 908/12.14

F = 74.79N

The tension in the strap = 74.79N

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by mathematical calculations before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of uranus led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
