The pesticide DDT was first made by a chemical company in 1939 and became widely used worldwide. Evidence that DDT builds up in

animal tissues and may cause health problems such as cancer and damage to organs, as detailed in Rachel Carson’s book Silent Spring, resulted in DDT being banned in the US in 1972. How do you suppose science and society were affected by the ban of DDT?

It worked

DDT or Dichlorodiphenyltrichloroethane is a kind of pesticide that's colorless and tasteless in form. It has been a known pesticide used for agricultural purposes in the US.It was banned because of its known effects and impact to both humans and other living organisms. A book published by Rachel Carson entitled "Silent Spring" exposed the truth that DDT can cause cancer to humans and is an agricultural threat to wildlife, particularly birds like the bald eagle and the peregrine falcon who were almost near-extinction before the said pesticide was banned.

A wave is propagating from left to right in a medium. The particles in the medium are also vibrating from left to right. What ki
Anna71 [15]
Based on the direction of propagation compared to direction of vibration, waves are classified into:
1- Transverse waves: The direction of propagation of the wave is perpendicular to the direction of vibration of the medium particles.
2- Longitudinal waves: The direction of propagation of the wave is the same as the direction of vibration of the medium particles.

For the question we have here, since the direction of the wave is the same as the direction of vibration of particles, therefore, this wave is a longitudinal wave

How much heat Q1 is transferred by 25.0 g of water onto the skin? To compare this to the result in the previous part, continue t
hodyreva [135]

Answer:

The heat transferred  from water to skin  is 6913.5 J.

Explanation:

Given that,

Weight of water = 25.0 g

Suppose that water and steam, initially at 100°C, are cooled down to skin temperature, 34°C, when they come in contact with your skin. Assume that the steam condenses extremely fast. We will further assume a constant specific heat capacity c=4190 J/(kg°K) for both liquid water and steam.

We need to calculate the heat transferred  from water to skin

Using formula for stream

Q=mc\Delta T

Put the value into the formula

Q=25\times10^{-3}\times4190\times(373-307)

Q=6913.5\ J

Hence, The heat transferred  from water to skin  is 6913.5 J.

Jin walked 4 km on a straight path to get to the sandwich shop. He traveled 30° south of east.
Molodets [167]

Answer: -2 km

Explanation:

If we imagine Jin's movement to be the hypothenuse of a right triangle, then the southern component of Jin's movement corresponds to the side of the triangle opposite to the angle of 30 degrees. Therefore, the magnitude of this southern component is given by

However, the angle of 30 degrees is south of east: this means that the direction of this southern component is south, and since we generally take north as positive direction, we must add a negative sign, so the correct answer is

-2 km
