The elements fluorine and chlorine can form minerals in the "halide"group
.
Halide refers to the group containing halogens. The halogens turn out to be less responsive as you go down the group. Fluorine, at the highest point of the group, is the most responsive or reactive halogen. It is to a great degree risky, causing serious synthetic consumes on contact with skin.
Halogens also act as bleaching agents.They will evacuate the shade of colors. Chlorine is utilized to bleach wood mash to influence white paper.
Answer:
I would say since it is still water the stream flow is 0km/h. Especially because he needs the same time upstream as He does down stream.
Answer:
The <u>HIGHER</u> value of coefficient of friction the greater the resistance to sliding
Explanation:
As we know that friction force is given by

so friction force is the product of friction coefficient and normal force.
So here we can say that if friction coefficient is higher then the friction force will be more as it is product of friction coefficient and normal force.
So correct answer will be given as
The <u>HIGHER</u> value of coefficient of friction the greater the resistance to sliding
Answer:
324.3Nm
Explanation:
The torque is given by the equation

in this case the vectors r and F are perpendicular between them, thus:

The forces acting on the mass are:
(1)
where T is the tension of the cable, M is the mass and a is the acceleration.
Furthermore, we have that the acceleration is:

By replacing in (1) we can obtain:

The force T produces the torque on the pulley, hence:

the answer is 324.4Nm
hope this helps!
