natita [175]

Question : 1

  • mass (m) = 1000 kg
  • velocity (v) = 5 m/s

=》

k.e =  \dfrac{1}{2}mv {}^{2}

=》

k.e =  \dfrac{1}{2}  \times 1000 \times (5) {}^{2}

=》

k.e = 500 \times 25

=》

k.e = 12500 \: joules

kinetic energy = 12500 joules

Question : 2

  • mass (m) = 10 kg
  • velocity (v) = 5 m/s

=》

k.e =  \dfrac{1}{2} mv {}^{2}

=》

k.e = \dfrac{1}{2}  \times 10 \times  ({5})^{2}

=》

k.e = 5 \times 25

=》

k.e = 125 \: joules

kinetic energy = 125 joules

Question : 3

  • mass = 100 kg
  • velocity = 5 m/s

=》

k.e =  \dfrac{1}{2} mv {}^{2}

=》

k.e =  \frac{1}{2}  \times 100 \times (5) {}^{2}

=》

k.e = 50 \times 25

=》

k.e = 1250 \: joules

kinetic energy = 1250 joules

Define neuron and nerve<br>cell​
san4es73 [151]

Answer: Hi!

A neuron is a basic working unit of the brain. Neurons are special cells designed to transfer information to other nerve, muscle, or gland cells. They are pretty cool - looking too! (A slightly irregular circular shape with branches reaching out from all sides.) A neuron is a nerve cell. Nerve cells are the way of communication in the nervous system.

Hope this helps!
