B) increasing
C) decreasing
D) negative
The horizontal component of the velocity remains constant in a trajectory course.
Answer: A
Explanation:
The trajectory path is formed due to the gravitational pull acting on the object thrown from some point either upward or downward.
As it is known that the velocity is divided into horizontal and vertical component, the vertical component of the velocity of the object thrown will be mainly influenced by the gravitational pull as it acting in vertical direction only.
So the vertical component of the object following a trajectory path will be changing at a rate of 9.8 m/s2 which is the acceleration due to gravity.
On the other hand, the horizontal component of the velocity will remain constant in order to maintain the law of conservation of energy.
im not 100 percent sure but i think its a
Answer:
Explanation:
The gravitational field strength at a point is the gravitational force exerted per unit mass placed at that point. This means that the gravitational field strength, g {\displaystyle g} is equal to the force experienced by a mass of 1 kg in that gravitational field.
Power is defined in physics as the quantity of energy transported or transformed per unit of time. To calculate power, divide the amount of energy transferred by time.
Power is defined in physics as the quantity of energy transported or transformed per unit of time. The watt is the unit of power in the International System of Units, equivalent to one joule per second. Power is also referred to as activity in ancient writings. A scalar quantity is a power.
The formula for power is given as the ratio of energy transferred to the time taken.
Its SI unit is Watt, while the SI units for energy and time are seconds. Therefore, we can write,
Power = Energy transfer / Time taken
Joule = Watt / Second
Hence, To calculate power, divide the amount of energy transferred by time.

Your answer should be Cold Blooded Animals. Cold blooded animals don't have control over their own body temperature like humans or mammals do, most times cold blooded animals are reptiles, amphibians, etc. so they have to lay on rocks or someplace in the sunlight to warm up and have to go to water or shady areas to cool off. Hope this helps! =^-^=
