The atomic number of the atom is 13. This means that its electronic configuration is (2 8 3) or in other words:
1<span>s2, </span>2<span>s2, </span>2<span>p6, </span>3<span>s2, </span>3<span>p<span>1
If three electrons are lost, then these electrons are removed from the outermost level.
In our case, electrons are removed from the third energy level (one electron is removed from the 3p orbital and two electrons are removed from the 3s orbital).</span></span>
Answer:
Option A
Explanation:
Velocity is expressed as distance covered per unit time, with respect to direction. Therefore, v=d/t
Given distance west as 60 km and time as 1.33 then velocity will be
V=60/1.33=45.112781954887 km/h
Rounded off as 45.11 km/h West
Velocity in East will also be given by substituting 40 km for d and 0.67 h for h hence
V=40/0.67=59.701492537313 km/h rounded off as 59.70 km/h East
Taking East as positive then West as negative, the sum of two velocities will be (59.70+-45.11)/2=7.295 km/h East
Approximately 10 km/h East since it is positive
Answer:
Explanation:
velocity of ball in train reference = v2
velocity of ball in earth reference = v1+v2
(a)
Kinetic energy is given by 
where m and v are the mass and velocity of object respectively.
Change in kinetic energy is given by subtracting initial kinetic energy from the final kinetic energy. In this case
Initial kinetic energy= 
Final kinetic energy= 
Change in kinetic energy=
(b)
Change in velocity in train reference will be
Initial kinetic energy=
Final kinetic energy= 
Change in kinetic energy=
(c)
Work done, W = change in kinetic energy=
(d)
Work done, W = change in kinetic energy=
Answer:
Sensory transduction
Explanation:
The term sensory transduction refers to the conversion process where the sensory energy is converted in order to change the potential of a membrane.
In other words, it can defined as the process of energy conversion such that stimulus can be transmitted or received by the sensory receptors and the nervous system may initiate with the sensory receptors.
Transduction takes in all of the five receptors of the body. Thus skin is also one of the receptors and hence conversion of heat energy into impulses takes place with the help of thermo-sensory neuron.
Answer:
a) 0,1613 Hz
b) 1,01342 rad/sec
c) 9.5422 m
d) 
Explanation:
In the Albert Michelson exhibit at Clark University, we know the period of oscillation of the chandelier is T = 6.2 seconds
The chandelier will be modeled as a simple pendulum
a) Since the frequency is the reciprocal of the period, we have
b) The angular frequency is computed as
c) The period of a simple pendulum is given by
Where L is its length and g is the local acceleration of gravity (assumed 9.8 
for this part)
We want to know the length of the pendulum, so we isolate L
d) While hanging out in J.J. Thompson’s House O’ Blues, the new period is 6.2+0.11=6.32 sec. Since the chandelier is the very same (same length), we can assume the gravity is slightly different. We use again the formula for T, but now we'll isolate g as follows
Which results
