The car mas more mass than a bicycle. Newton's second law states force equals mass times acceleration.
Answer:
F=5.7×10⁻⁶
Explanation:
Not knowing a formula outright, I decided to follow the units of some relationships I did know. Radiation pressure is defined as force per area and also intensity divided by velocity (the speed of light here of course). Breaking intensity down into power per area and isolating force gave me the relationship F=(Power/Velocity),where power is given and the velocity is a constant.
My work is in the attachment, where I double checked the units too, comment with any questions.
The correct answer is C. Velocity is a vector and requires a direction.
Explanation:
In physics both speed and velocity are used to study the motion of a body; however, they are slightly different. In the case of speed, this describes the rate of change in position based on distance and time, because of this, speed is based on a magnitude or quantity. On the other hand, velocity is a vector because it does not only includes a change of position but the direction of motion usually based on a specific location reference.
Considering this, it can be concluded the difference between speed and velocity is that "velocity is a vector and requires a direction" because velocity includes both the distance and time (speed) along with the direction while speed focuses only on time and distance.
cardiovascular fitness: 3, 4, 7
flexibility: 1, 5
muscular fitness: 2, 6
The energy content is decreased and so is the particle speed.
