This time particle A starts from rest and accelerates to the right at 65.5 cm/s

FrozenT [24]

Answer:

t = 4 s

Explanation:

As we know that the particle A starts from Rest with constant acceleration

So the distance moved by the particle in given time "t"

$d = v_i t + \frac{1}{2}at^2$

$d = 0 + \frac{1}{2}(65.5)t^2$

$d_1 = 32.75 t^2 cm$

Now we know that B moves with constant speed so in the same time B will move to another distance

$d_2 = 44 \times t$

now we know that B is already 349 cm down the track

so if A and B will meet after time "t"

then in that case

$d_1 = 349 + d_2$

$32.75 t^2 = 349 + 44 t$

on solving above kinematics equation we have

$t = 4 s$

An Arrow (0.5 kg) travels with velocity 60 m/s to the right when it pierces an apple (1 kg) which is initially at rest. After th

Rom4ik [11]

Answer:

Velocity after collision will be 20 m/sec

Explanation:

We have given mass of arrow $m_1=0.5kg$

Mass of arrow $v_1=60m/sec$

Mass of apple $m_2=1kg$

Apple is at rest so velocity of apple $v_2=0m/sec$

According to conservation of momentum

Momentum before collision is equal to momentum after collision

$m_1v_1+m_2v_2=(m_1+m_2)v$

$0.5\times 60+1\times 0=(0.5+1)v$

$1.5v=30$

v = 20 m/sec

A thermosensory neuron in the skin converts heat energy to nerve impulses via a conversion called

Sav [38]

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.
