Well, since you provide no options, The effect of DDT on society can be characterized as dangerous / Hazardous
Even Though it is somehow effective to kill the mosquitoes, DDT is proven to cause cancers and potentially male infertility

hope this helps

The correct answer for above statement is:

both positive and negative .

Explanation:

DDT should be used "with caution" in fighting malaria,DDT (dichlorodiphenyltrichloroethane) was condemned in Britain in 1986 and prevented as a pesticide worldwide under the Stockholm Convention in 2001 after it was determined to be hazardous to wildlife and the environment.

The 15 environmental health specialists, who evaluated almost 500 health studies, decided that DDT "should be used with caution, only when needed, and when no other adequate, safe and affordable dilemmas are locally accessible.

What are the conditions required for a rigid body to be in translational equilibrium?

kolezko [41]

Answer:

Explanation:

The condition for translation equilibrium is that is that the net force acting on the body must be zero.

The sum all the external forces acting on the body in horizontal as well as vertical direction must be zero.

∑Fₓ=0 and ∑Fy=0

now if the above two condition are satisfied the rigid body is said to be in translational equilibrium.

God bless... hope this help to clear your doubt.

Four different resistors have various amounts of electric current flowing through them.

salantis [7]

Answer:

Order will be Forth resistor , first resistor, second resistor, third resistor

Explanation:

We have given four different resistance and current flowing through them

In first resistor resistance R = 4 ohm and current flowing i = 6 A

According to ohm's law voltage = current × resistance = 6×4 = 24 volt

In second resistor resistance R = 2 ohm and current i = 9 A

So voltage V = 9×2 = 18 volt

In third resistor resistance R = 2 ohm and current i = 3 A

So voltage V = 3×2 = 6 volt

In forth resistor resistance R = 8 ohm and current i = 8 A

So voltage V = 8×8 = 64 volt

So order of highest voltage to lowest voltage is 64,24,18,6

Forth resistor , first resistor, second resistor, third resistor

What causes the random, zig-zag movement (Brownian motion) of smoke particles suspended in air?

lidiya [134]

Answer:

It is caused by air molecules colliding with smoke particles

Explanation:

To start with, Brownian motion is the erratic or irregular movement of very small particles in a medium due to continuous bombardment by molecules that surround the medium.

Thus, smoke moves in a Zig-Zag manner (Brownian motion) due to continious air bombardment. If it were pollen grain suspended in water, the erratic movement (Brownian motion) of the grains is caused by bombardment from water molecules.
