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.
Explanation :
In transverse waves the particles are oscillating perpendicular to the direction of propagation of waves.
The uppermost part of the wave is crests and the lowermost part is troughs.
Wavelength of a transverse wave is defined as the distance between two consecutive crests or troughs.
Amplitude is the maximum distance or displacement covered by a wave.
So, crest, amplitude, trough and wavelength identifies the parts of a transverse wave.
Answer:
Magnitude of the force on proton = F = 3.84 × 10^-14 N
Explanation:
Charge on proton = q = 1.60 × 10^-19 C
Velocity of proton = V = 4.0 × 10^4 m/s
Magnetic field = B = 0.20 T
Angle between V and B = θ = 60
where,
F = magnetic force ( N )
B = magnetic field strength ( T )
q = charge of object ( C )
v = speed of object ( m/s )
θ = angle between velocity and direction of the magnetic field
Solution:
Answer:
40m approximately
Explanation:
Given
Force =377N
Mass =86.5kg
Velocity =13.2m/s
Required
Radius of the track
The expression for the centripetal force acting on the cyclist is
F=mv²/r
Make r subject of the formula
r= mv²/F
Substitute
r=86.5*13.2²/377
r= 15,071.76/377
r=39.97
r=40m approximately
The outlaw that was <span>executed by hanging "in the spring of '25" is identified as the HIGHWAYMAN.
This is one of the characters in the song, "American Remains", sang by The Highwaymen. The group consisted of </span><span>Johnny Cash, Waylon Jennings, Willie Nelson and Kris Kristofferson. Other characters in the song were a sailor, a dam builder, and a pilot of a starship.
</span>
This is the first stanza of the song:
"I was a highwayman. Along the coach roads I did ride
<span>With sword and pistol by my side </span>
<span>Many a young maid lost her baubles to my trade </span>
<span>Many a soldier shed his lifeblood on my blade </span>
<span>The b*stards hung me in the spring of twenty-five </span>
<span>But I am still alive."</span>
