Answer:
Thalamus
Explanation:
Thalamus is a mass of gray matter located just above the brain stem, between the cerebral cortex and the midbrain. It plays a role in pain sensation, attention and alertness. It consists of four parts: the hypothalamus, the epythalamus, the ventral thalamus and the dorsal thalamus.
It (Thalamus) serves as the major relay station for most sensory impulses that reach the primary sensory areas of the cerebral cortex from the spinal cord and brain stem.
Answer:
Speed in kilometer/hour = 6 kilometer / hour
Explanation:
Given;
Time taken to cover distance = 15 minute = 15 /60 = 0.25 hour
Distance of school = 1.5 kilometer
Find:
Speed in kilometer/hour
Computation:
Speed in kilometer/hour = Distance / Time
Speed in kilometer/hour = Distance of school / Time taken to cover distance
Speed in kilometer/hour = 1.5 / 0.25
Speed in kilometer/hour = 6 kilometer / hour

You would need to connect a potential difference across a resistor in parallel
Answer:
141
Explanation:
The atomic number (Z) corresponds to the number of protons:
Z = p
while the mass number (A) corresponds to the number of protons+neutrons:
A = p + n
So the number of neutrons in a nucleus is equal to the difference between mass number and atomic number:
n = A - Z
For the initial nucleus of Uranium, Z = 92 and A = 235, so the initial number of neutrons is
n = 235 - 92 = 143
An alpha particle carries 2 protons and 2 neutrons: so, when the isotope of Uranium emits an alpha particle, it loses 2 neutrons. Therefore, the number of neutrons after the decay will be
n = 143 - 2 = 141
