Scalar is a quantity such as mass or length that is completely determined by its own magnitude and has no direction. Therefore, your answer is Speed.
Answer:
we know,
Power=work done\time taken
=10\2
=5 watt
An incandescent bulb produces light that comes from the heating of a filament. A compact fluorescent bulb produces light when a substance is hit by electromagnetic radiation. Compact fluorescent bulbs are more efficient than incandescent bulbs.
The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic processes. Therefore, a system with lower heat emissions would be more efficient.
The second law of thermodynamics states that the total entropy of an isolated system (the thermal energy per unit temperature that is unavailable for doing useful work) can never decrease. In our context, it means that the system with the least amount of losses would be more efficient. As a conclusion the fluorescent bulb would be more efficient.
"You may use the text book, class notes, current event articles and previous assessments as resources. You may not, however, receive help from any other person in completing the examination" is TRUE.
<u>Answer:</u> Option A
<u>Explanation:</u>
It become time taking on searching everything by own and specially without guidance or presence of an individuals support. But that process also train one in selecting resources wisely rather than going in quantity and attractiveness, one start choosing simple and quality based.
Many resources also become reason of failure, because it create complexity and eat more time, with less efficiency. But composed and limited material always leads to good qualification and shows independence of achievement.
Explanation:
A projectile motion may be defined as that form of a motion that is experienced by an object or a particle which is projected near the surface of the Earth and the particle moves along the curved path subjected to gravity force only.
Thus a projectile motion is always acted upon by a constant acceleration due to gravity in the down ward direction.
In the context, Quinn shoots two particle x and y from his sling shot and he observes that both his projectiles travels in a parabola curve in the air. Both the object x and y touches the ground a distance apart from him which is known as the range and it depends upon the velocity of the projectile. Both the projectile reaches a maximum height and then drop on the ground in a parabola shape.
