Answer:

False.

Explanation:

The hypothesis can be defined as the explanations or suppositions that are acceptable in order to prove some natural phenomena by the help of experimental procedure.

And you can use your data which is gather from the experiment and formulate a new hypothesis.

A hypothesis is the data which is not depend on the experimental data, it can be say that it is just a not dependent hypothesis.

This is false. Your hypothesis, or prediction, is just that: a prediction. Saying its a failure will result in bias.

The coefficient of static friction between a book and the level surface it slides on is 0.65. If the mass of the book is 0.2 kg,

just olya [345]

Answer: 1.274 N minimum force required to slide the book across the surface

Explanation:

Mass of the book = m = 0.2 kg

Normal force acting on the book,N = mg

Coefficient of friction = $mu_s$ = 0.65

Minimum force required to slide the book across the surface= F

$F=\mu_s\times N$

$F=0.65\times 0.2 kg\times 9.8 m/s^2=1.274 N$

1.274 N minimum force required to slide the book across the surface

6A certain load and set of slings create a 20-degree angle between the load and each sling leg. Using a spreader for the same li

Otrada [13]

Solution:

The angle between the sling and the load is $20^{\circ}$

So the tension in each sling can be calculated as

$Sin \theta = Mg => T = \frac{Mg}{2Sin\theta}$

$Sin \theta=> \frac{Mg}{2Sin 20^{\circ}}$

Where

M is the mass of the load

The Horizontal reaction on the sling will be inward.

After using the spreader, the new angle between sling and load is $60^{\circ}$ , the tension in the sling will be

$T= \frac{Mg}{2 Sin 60^{\circ}}$ = $\frac{Mg}{2 Sin 20^{\circ}}$

The tension will be same as before in the sling move away through the spreader at an angle more than 90 degree the horizontal force will act opposite and will be outward
