Answer:
Explanation:
1. The beam emitted travels along a straight path and it is divergent in nature. It has its radius increasing progressively as the distance away from the source of light increases.
2. It would be observed that the region where the bulb is positioned has denser light beam. This gets fainter towards the edges of the beam and away from the bulb.
Answer:
25116 J
Explanation:
Q = m × c × ΔT
c = 4.186 J/g°C
M=200 g
So,
Q = 200 × 4.186 × (40-10)
=200 × 4.186 × 30
=25116 J
Answer:
The statement is false.
Explanation:
Passive transport moves molecules from one side of the membrane to the other with the energy of the chemical gradient (or concentration gradient). Otherwise, active transport uses the hydrolyzation of ATP to gain energy in order to move molecules across the membrane without taking into account the gradient.
