A power supply A basic motor has a DC power source, in general. It supplies power for the motor or field coils armature. Field Magnet can be a permanent magnet or electromagnet The magnetic field tends to generate a torque on the spinning armature coil by virtue of Fleming's lefthand rule.
Answer:
810 kJ
Explanation:
Work done is equal to change in kinetic energy
W=∆KE
Change in kinetic energy is given by
∆KE=½m(v²-u²)
Where ∆KE is the change in kinetic energy, m is mass of the vehicle, v is final velocity while u is initial velocity.
Since the vehicle must come to rest, the final velocity is zero.
Substituting 1800 kg for m, 0 m/s for v and 30 m/s for u then
∆KE=½*1800(0²-30²)=-810, 000J
Converted into kJ
∆KE=-810 kJ
Therefore, work done is 810 kJ
In this problem, the goat is a noun and the "slow" is acting like a verb(supposed to be an adjective but whatever...)
<span>Only objects are able "to do verbs"; That's why nouns, proper nouns, etc. are able to carry out an action. Verbs, adjectives, adverbs, etc. can't carry out actions
</span>
Example:A slug can snail but a snail can't slug
A snail can twist but a twist can't snail
Jumping can't Run and therefore, Running can't jump.
