Physics is explicitly involved in studying <span>the motion of a spacecraft under gravitational influence. Thus the answer is C.
Physic focuses more on the measurement, gravity, distances, acceleration and motion. THough all the choices are sciences but the C. is the topic that physics is involved.</span>
Your answer would be
D. Gasoline-powered cars are better for past acceleration and traveling at high speeds.
I just took this quiz and can confirm this is the correct answer!
Hope this helps :)
Answer:
The system analysis phase of the SDLC includes four main activities: requirements modeling, data and process modeling, object modeling, and consideration of development strategies.
Explanation:
- SLDC is a Software Development Life Cycle. It is basically a process of designing, developing and testing high-quality software by a software developing industries.
- It has four processes as mentioned in the question which is a process for improving and refining the quality of software.
- SLDC is a methodology that is used by every software company to develop a fine and high-quality software.
Answer:
The velocity of Dan is 1.13 m/s.
Explanation:
Given that,
Initial velocity of skateboard and Dan = 2.00 m/s
Velocity of skateboard = 7.00 m/s
Mass of Dan m= 40.0 kg
Mass of skateboard M= 7.00 Kg
Suppose How fast is Dan going as his feet hit the ground?
We need to calculate the initial velocity of Dan
Using conservation of momentum
Put the value into the formula
Hence, The velocity of Dan is 1.13 m/s.
