Answer:
fossil fuels are natural and limited, nuclear is man made and more toxic
Explanation:
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.
The answer would be:
C. An unbalanced force has acted on the vehicle.
The presence of an unbalanced force will accelerate an object, the second law of motion dictates this (Although not explicitly). Lets knock out the rest of the choices.
If a balance force acted on the vehicle, then the vehicle would be at rest. The mass of the vehicle did not change (Unless it falls apart, which I doubt). The direction of the vehicle does not change and it will only do so if another force and a stronger one at that will counteract the current net force acting on the vehicle.
Hope you got your answer here, although you did not ask for an explanation, maybe this will help you figure some of the other questions you have on your own.
Speed = 11000 m/s = 11km/s
D = 380000 km,
t = D/s = 380000 km/ 11km/s
t = 34 545.45 seconds.
The direction of the angular velocity of the single wheel is the clockwise direction
<h3>Angular velocity</h3>
The angular velocity is the number of revolutions per second of the single wheel. It is given by ω = v/r where
- v = linear speed of the wheel and
- r = radius of the wheel.
<h3>Direction of the angular velocity of the single wheel</h3>
Since the wheels moves forward and the velocity of the wheel is always tangential to the wheel causing it to move forward, its angular velocity is in the clockwise direction
So, the direction of the angular velocity of the single wheel is the clockwise direction
