Answer:
newton's third law of motion
Explanation:
The model of balloon car is example of newton's third law of motion which says that to every action there is always and equal and opposite reaction. As the balloon is inflated and then release the nozzle, the rubber contacts and pushes the air forward out of the nozzle, the air pushes back on the rubber and propelling the balloon forward.
Answer: set of rules based on standards and guidelines.
Answer
a) Top speed of the roller coaster, v = 15 m/s
Maximum height reached by the roller coaster, h = ?
Using conservation of energy
b) Maximum height, H = 80 m
Top speed of the roller coaster, v = ?
Using conservation of energy
Answer:
a) No-Load Current will increase
b) The magnetising reactance will increase
c) The secondary voltage will decrease
Explanation:
a) when an air ap is made in the transformer core then more current is required for the magnetisation of core. Hence, no-load current will incraese.
b) with the air gap the magnetomotive force increases. As a result, the angle between the voltage and current increases. Consequently, power factor decreases. Power factor always decreases when the reactive behaviour of circuit incraeses. Hence, Magnetisation reactance will increase.
c) Secondary voltage decreases due to air gap. Therefore, it is said that with the air gap the efficiency of the transformer decreases.
Therefore, it is safe to say that as the mass of an object<span> increases so does </span>its <span>inertia. ... Mass and </span>velocity<span> are both directly proportional to the </span>momentum<span>. </span>If<span> you increase either mass or </span>velocity<span>, the </span>momentum<span> of the </span>object<span> increases proportionally. </span>If<span> you </span>double<span> the mass or </span>velocity<span> you </span>double<span> the </span>momentum<span>.</span>
