The correct answer is option D, Most people believe that drinking milk can soothe heartburn.

Reason -

Pseudoscience is a science in which facts and belief are considered to be existing but  they lack any scientific logical backing.  

Here all the three options A, B and C have been proved and well established except the last one. It’s a general belief of people that drinking  milk  soothes out heartburn but no scientific investigation has yet accepted the fact.

A 17 kg box experiences an applied force of +175 N and a force of friction of -125 N. While experiencing these unbalanced forces
Flura [38]

Answer: (b)

Explanation:

Given

Mass of box m=17\ kg

Applied force F=175\ N

Friction force f=-125\ N

Box travels a distance of s=15\ m

time taken t=5.25\ s

Net unbalanced force F_{net}=175-125=50\ N

Work done by the unbalanced force

\Rightarrow W=F_{un}\cdot s\\\Rightarrow W=50\times 15\\\Rightarrow W=750\ N

Power developed by unbalanced force

\Rightarrow P=\dfrac{W}{t}\\\\\Rightarrow P=\dfrac{750}{5.25}\\\\\Rightarrow P=142.85\approx 1423\ W

Thus, option (b) is correct.

Calculate the power of a crane if it lifts a load of 2400N through a height of 10m in 15 seconds.Also express the power in horse
dem82 [27]

Answer:

<h2>2.08 hp</h2>

Explanation:

The power of the crane can be found by using the formula

p =  \frac{f \times d}{t}  \\

f is the Force

d is the distance

t is the time taken

From the question we have

p =  \frac{2400 \times 10}{15}  =  \frac{24000}{15}  \\

We have

power = 1600 W

But 1 W = 0.0013 hp

So 1600 = 2.08 hp

We have the final answer as

<h3>2.08 hp</h3>

Hope this helps you

an object is acted upon by a force of 22 Newtons to the right and 13 Newtons to the left what is the magnitude and direction of
frosja888 [35]

22N to the right and 13N to the left

Forces are in opposite directions so you subtract the bigger force from the smaller force

Magnitude of force= 22N -13N

= 9N

net force direction is to the right
