2. Why do some clouds rain while others do not?
andreyandreev [35.5K]

Some clouds do not rain and others do because the clouds that do not rain do not have enough water in them. White clouds are ones that do not have enough water in them.

A device that transforms electrical energy to mechanical energy is a
yarga [219]

Answer:

Electric Motor

Explanation:

There are mainly two types of machines for inter-conversion between mechanical energy and electrical energy as under:

  1. Motor
  2. Generator

Motor is a device which converts electrical energy into a mechanical whereas generator does the exact opposite of motor.

There are 2 types of motors:

AC Motor - Converts alternating current into mechanical energy

DC Motor - Converts direct current into mechanical energy

Chris shoots an arrow up into the air. The height of the arrow is given by the function h(t) = - 16t2 + 64t + 23 where t is the
Ghella [55]

Completing the square gives the answer right away.

-16t^2+64t+23=-16(t^2-4t)+23=-16(t^2-4t+4-4)+23=-16((t-2)^2-4)+23

\implies h(t)=-16(t-2)^2+87

which indicates a maximum height of 87 when t=2.

When a new path of lesser resistance is made for an existing circuit a(n) _____________ circuit occurs.
Margaret [11]

When a new path of lesser resistance is made for an existing circuit a(n) short circuit occurs.

<h3>What is short circuit?</h3>

An electrical circuit short circuit is when two nodes that are supposed to be connected at different voltages make an improper connection. This leads to an electric current that can damage circuits, cause overheating, fire, or explosions, and is only constrained by the network's remaining nodes' equivalent Thevenin resistance. While short circuits are typically the result of a failure, they can occasionally be brought on purpose, such as when voltage-sensing crowbar circuit protectors are being installed.

An electrical connection that requires two nodes to have the same voltage is known as a short circuit in circuit analysis. Since there is no resistance and hence no voltage drop across the link in a "perfect" short circuit, there is no short circuit.
