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
This problem illustrate an airplane which is decelerating, since it tells us about a braking force, this type of acceleration is opposite in direction or simply a "deceleration" of the aircraft. The given are mass m=3.55 x 10⁵ Kg. The net braking Force f=-4.05 x 10⁵ N or Newton. The formula for the force is equivalent to F=ma. therefore a=f/m or force divided by the mass. This braking force is acting in opposite direction therefore having a negative sign. The answer will be negative in sign reminding us that it is a form of "deceleration". The unit should be in m/s².
Answer:
= 729 Joules
Explanation:
Heat absorbed by a substance is given by the formula;
Q = m×c×ΔT
Where; Q is the heat absorbed
m is the mass of the substance
ΔT is the change in temperature;
The specific heat capacity of iron is 450 J/Kg/K
Therefore;
Heat absorbed = 0.06 kg × 27 × 450
= 729 Joules
When a liquid freezes:
• The particles still vibrate
• The particles move together into organised rows and columns into a fixed position
• And the density of the substance increases
The third option is the answer. low voltage and high current.
<span>From regional transmission, electricity distributed to our homes is in low voltage and high current.
Electricity from main power house is step up to higher voltage to reduce the losses of energy and then step down to lower voltage in regional transmission house.</span>
