Answer: In vision, the ventral stream controls identification of an object, and the dorsal stream controls action toward the object.
Explanation: The ventral stream is associated with object recognition and form representation.
Dorsal stream a pathway that carries visual information from the primary visual cortex to the parietal lobe.
Hope it helps :)
Answer:
10.8 N
Explanation:
The question requires the force between them, hence, we only need the magnitude of the force without considering what direction it's acting.
Parameters given:
Q1 = 15 * 10^(-6) C
Q2 = 10 * 10^(-6) C
The diagram explains better.
The electrostatic force BETWEEN Q1 and Q2 is:
F = (k * Q1 * Q2)/r²
Using Pythagoras theorem:
r² = 0.25² + 0.25² = 0.0625 + 0.0625
r² = 0.125
=> F = [9 * 10^9 * 15 * 10^(-6) * 10 * 10^(-6)]/0.125
F = 1.35/0.125
F = 10.8 N
Explanation:
Incident light makes an electron oscillate. The electrons emit light or absorb the light, collide with other electrons, thereby converting light energy to more internal energy. and convert it to heat.
Light wave of a given frequency is incident on a material with electrons having the same vibrational frequencies, then electrons absorb the energy of the light wave and transform it into vibrational motion.
Answer:
290
Explanation:
Average acceleration is the change in velocity over change in time.
First, find the velocity by taking the derivative of position.
v(t) = dx/dt
v(t) = 38t + 21t²
At t = 3 and t = 9:
v(3) = 303
v(9) = 2043
So the average acceleration is:
a = Δv / Δt
a = (2043 − 303) / (9 − 3)
a = 290
Use appropriate units.
