Answer:
assembled
Explanation: because it was last weekend it was in the past so the past tense of assembled must be used
Since a typical smelt has 1.04 ppm of PCB is great lakes. So
the amount of PCB in a smelt in great leak can be calculated by multiplying the
mass of smelt by the pcbs present in a smelt
225 g * ( 1.04/100000) = 2.34 x10^-4 g pcbs
Answer:
A.
Explanation:
The speed or celerity of deep-water waves increases with increasing water depth.
With increase in depth, the pressure inside the increases as p=ρgh.
And with this increase in pressure force associated with waves increase because force is directly proportional to the pressure. Now greater the force greater will be accleration and greater velocity is obtained.
Answer: No change in mass
Explanation:
Beta-emission: In this process, a neutron gets converted into a proton and an electron. The electron is referred to as a beta-particle. The beta particle released carries a charge of -1 unit and has negligible mass.
General representation of an element is given as:
Z= Atomic number
A = mass number
X = chemical symbol of element
Answer:
option (D)
Explanation:
your distance from the plane mirror = 2.4 m
According to the property of the plane mirror, the distance between the object and the mirror is equal to the distance between the image and the mirror.
So, the distance between you and your image is two times the distance between you and mirror.
the distance between you and your image = 2 x 2.4 = 4.8 m
